Introduction

In this article I'll run you through the steps of ramping up the voltage on your X800 (Pro/Pro VIVO/XT/XT PE). As always, the familar warning of "This will void the warranty" and "We take no responsibility of any kind should you damage your video card" applies before we start. Remember to take your time and don't over do it. You should seriously consider replacing the stock HSF if you plan to crank high on the overclock . Check out our GPU Heat Sink Fan Reviews here (http://www.techpowerup.com/reviews). Also, should you have any questions or information you wish to share, please post them here (http://forums.techpowerup.com/showthread.php?t=663).

Before you Begin

I'd like to make clear a important side note before you begin. In regards to "How hot is too hot?", I see and receive this question a lot. First I want to post ATI's official X800 GPU temp specs.


<table><tr><td>Thermal Parameter Value</td><td>temperature</td></tr>
<tr><td>Maximum recommended ASIC case (or center of die backside for flip chip)</td>
<td>105°C</td></tr>
<tr><td>Absolute maximum rated junction temperature: TJmax</td><td>125°C</td></tr>
<tr><td>Minimum ambient operating temperature</td><td>0°C</td></tr></table>


Some interesting numbers to say the least. Having posted the info which should provide you with a base to which to compare your temps too, ie 80°C and even 90°C is still within specs. But having said that I'd like to share some words of wisdom from one named ViperJohn (http://imageevent.com/marginjohn/viperjohn)

ATI says 95°C is okay but it may not run clean either. I had an ASUS XT-PE that ran at 80C stone stock in the 3DM01se Nature torture loop. While they say it is okay there is a catch to running hot.
For every 10°C you increase a discrete parts (memory chips, cores, Mosfets, IC's, etc) average operating temperature you cut its lifespan in 1/2 what ever that given lifespan may be. Conversely for every 10°C you lower the average operating temperature you double the parts lifespan. It doesn't take a rocket scientist to conclude that a card that runs 60C will have an average life span that is 4 times longer than if the same card runs 80°C.

The above is the reason that a properly modded card can have a longer lifespan that the same card will stock.

John

So before you put the juice to that piece of hardware keep those words in the back of your mind.

Since most people prefer the pencil method, I'll start with that vmod first and come back to the resistor vmod.

Tools and Supplies

Digital Multimeter (a must have to complete mod safely)
Electrical Tape (get the color that matches your PCB)
2b Pencil (works the best, found one at Staples in Drafting Department)


I like to use Alcohol (99% Isopropyl Alcohol) and a Qtip to clean the graphite off the resistor. If I've brought the resistance down to low, I'll dab the dry end on the resistor a couple of times and recheck the Ohm reading. If it doesn't bring it back up to where I want it, I'll wet the other side of the Qtip with Alcohol to clean and restart.

Getting Started
Before we get down to work, lets run through the multimeter to make sure we're on the same page. You'll be using two different settings. One to check the voltage before and after we make our changes. The second to check the resistance in Ohms of the resistors we're using our 2b pencil on to safely lower their resistance to raise the voltage. To check the voltage for the VCore and VMem starting measurements set the multimeter to DCV 20v and to check Ohm resistance you'll set the meter to Ohms 2k or 20k depending on the resistor we're working with.

I'd like to note that you don't need to do all of the next steps if you're not doing all of the vmods. Try the VCore vmod first then move on to the next one if you feel you need to.

So grab a pencil and paper (should already have a pencil) we're going to write down our starting voltages. Starting with Image 1 locate the green arrow pointing to the capacitor in the top right hand corner labeled C60. Now with the system running and the side cover off visually inspect the area to first locate the capacitor and making sure there isn't anything in the way. Set your meter to DCV 20 V before placing the black lead of your meter on the screw holding in the video card, this is ground. Important when touching card with a meter lead that you don't accidently ground something out. Carefully place the red lead on the top side of capacitor C60 (you're upsidedown from the pic facing the card). Your meter should be reading around 1.39v, cards vary from manufacture to manufacture. Write that VCore number down for future reference. There is not a measure point for the IGPU Vmod that I'm aware of at this time.

For the time being lets move on to the VDD (VMem) measure point. Again in Image 1 locate the green arrow pointing to our measure point, over to the left of the card labeled C213. A closer view in Image 3, it's the top capacitor in the top right hand corner. With the same steps we used in the previous measure point. Place the black lead on ground carefully placing the red lead on left side of C213 (you're upsidedown from the pic facing the card). Your meter should be reading around 2.00v. Write that VMem number down for future reference.

Next measurement we'll check before we start the mod will be VDDQ. Find the measure point in Image 1, green arrow pointing to capacitor C215. Right below the VDD capacitor, closer view in Image 3. Once more with the same steps as before place the black lead on ground carefully placing the red lead on the left side of C215 (you're upsidedown from the pic facing the card). Your meter should be reading around 2.08v. Write your VDDQ number down for, you guessed it, future reference.

Pencil Time

Time to shut down the system and take out the card, your work area should be static free. Yes, at this point you should be reading from a printed document. Basically what we are trying to do is use our 2b pencil to reduce resistance on the selected resistor. You'll need to measure the resistance in Ohms first, by placing the black lead on one side and the red lead on the other side of the resistor, write it down it's our starting Ohm reading. Then gently run your pencil along the side of the resistor from one end to the other. Do a couple swipes then check again with the meter. Using the number you've written down subtract the new reading. For example if your starting Ohm reading is .418k and your new ohm reading is .400k obviously it's a 18k ohm drop in resistance. If you go by the rule of 15k Ohms equals roughly .04 V to .06 Volts. Add the .04 V - .06 V to the reading that you saved for future reference, for example the VCore reading of 1.39 V your voltage should now be around 1.43 V - 1.45 V. A 10k variable resistor will give you around .04 Volts so again that's around 15 Ohms you need to reduce your resistor.
Keep in mind that if you want your card to last awhile don't get greedy.

VCore Vmod

Using Image 2 as our guide locate the the resistor R1597 that is under the pencil labeled VGPU. This is the resistor you will use the 2b pencil on following the steps we went through above. Set your multimeter to 20k Ohms. A VCore voltage of 1.45v to 1.50v should work well. After you have reduced the resistance place the card back in and power up. Check your VCore voltage again to verify the amount of voltage you're now running at. Test the card for artifacts and lockups. If all is well, use a piece of electrical tape and cover the resistor you modded. Review the max voltages we suggested for cooling needs.

GPU Over Current Protection Vmod

This mod is only needed if you are applying a high VCore vmod. This mod raises the limit that you can obtain with the VCore vmod. In Image 2we use a 20k Ohm reduction in resistance for OCP vmod, which is applied to resistor R1596. Since there isn't a measure point, remove the card and set your meter to 200k. Check the resistance on the resistor R1596 which should be around 40k Ohms. As \\mAr did lower the resistance by 20k Ohms. This one is in a tight spot so you may want to try to pencil the top of the resistor to make it easier.

VDD (VMem) Vmod

In Image 3 locate the VDD labeled pencil above the resistor R311. This is the resistor you will use the 2b pencil on following the steps we went through above. Set your multimeter to 20k Ohms. A 20k variable resistor which will give you around .08v Volts, you'll need to reduce the resistance around 30 Ohms. A VMem voltage of 2.08 V to 2.12 V will work fine. After you reduce the resistance place the card back in and power up. Check your VMem voltage to verify the amount of voltage you're running your memory at. As we did in the VCore vmod, test the card for artifacts and lockups. If you're loving life, tape that bad boy up.

VDDQ Vmod

This one will be a little tough given the resistor is in a tight spot. Looking at Image 3 the pencil labeled VDDQ above resistor R256, this is the one you'll need to pencil mod to increase VDDQ voltage. Set your meter to 2k Ohms this time. With the info of a 20k variable resistor giving .08 Volts we'll need to reduce resistance around 30 Ohms. A VDDQ voltage of 2.16 V to 2.18 V will help with both VCore and VMem. Check the voltage to verify the amount of voltage you're running at. Test for artifacts and lockups. Use the tape to keep the graphite in place.

My 2 Cents

Before I go into using soldered VR vmods I wanted to finish the pencil vmod section with my 2 cents worth. I tried to write the pencil vmod with newbies or first time modders in mind. The pencil mod can be applied easily and be effective if you take your time. Don't get caught up in seeing someone else's speed and think you can do it too. Not all cards oc the same and along with cooling methods can determine your final outcome. The forums (http://forums.techpowerup.com) here at techPowerUp! are filled with people who will not hesitate to help by answering a question. Even still if it all seems like too much you can always send your video card to ViperJohn (http://imageevent.com/marginjohn/viperjohn) who does quality voltmodding work.

[page=Variable Resistors]
Using Variable Resistors

This section I decided will be brief due to time restraints and less descriptive. Understanding the same warnings as posted previously in the begining of the article. You should read the "Introduction" and "Before you Begin" sections.

There are several VR How-Tos on the web. Each one has a different tweak, it's one of those more than one way to skin a cat deals. But we'll just do the basic VR to resistor solder.

http://www.techpowerup.com/articles/101/images/x800_small.jpg (http://www.techpowerup.com/articles/101/images/x800.jpg)

Image 6

Tools and Supplies

To do these mods you should aready have soldering skills and should be using a low wattage iron. I also assumed that you would be using a magnifying glass and until now didn't think to mention it.


Digital Multimeter (have to have one)
Glue Gun (to set VR in place)
Variable Resistors: 1x 10k Ohm, 1x 250k Ohm, 2x 20k Ohm


Take note at the top of the page for the Max Safe Voltages for different cooling.

Next read the "Getting Started" section to get your default voltage. This can be important to get an idea of where your voltage will be when you crank up the card. You can still use the same table as the pencil mod. What I mean by that is if the default Ohm reading of the VGPU is at 420 and you add the 10k VR, then given that a 10k VR will give you around .04v which in turn equals 15 Ohms then after adding the VR your new Ohm reading should be around 405 Ohms.

VR VGPU

Locating the resistor R1597 in Image 5 you will use the 10k VR. Set the VR to 10k or as close to 10k as it will go using your mulitimeter. Check the resistance on R1597 to compare after you solder the VR. You can either solder the VR to the resistor directly or you can use wires. After soldering the VR on check the resistance. Remember a 10k VR should give you around 15 Ohms. Test your card and verify the voltage.

VR IGPU Over Current Protection Vmod

Locate resistor R1596 in Image 5 and set your VR to 250k. Check the resistance on the resistor to compare after you solder the VR on. Again after soldering the VR on check the resistance. Like with the pencil mod you want to drop the resistence around 20k Ohms.

VR VDD (VMem) Vmod

Using Image 6 we will solder a 20k VR to the pins 5 & 7 of the VDD chip. Set the resistor to 20k and check the resistance before then after. Test your card and verify the voltage.

VR VDDQ Vmod

Same as the VDD vmod but on a different ISL6522CB chip below the VDD locate the VDDQ in Image 6. Just like the VDD set the VR to 20k and check the resistance before then after. Test your card and verify the voltage.

[page=Conclusion]
Conclusion

Remember to check and recheck before you place the card in and turn it on. By checking the resistence before and after can help deterrmine if you've made a mistake. Some may have you vmod and then test by placing the card in and powering it up. You don't drive blind, so don't mod blind.

Unlike the Pencil Vmod using the VR takes good soldering skills. I can contest to that and even though my soldering is rusty I still managed to do a few until I had slipped on my own card. Needless to say accidents do happen. So please take your time and be careful. But above all be safe.

[hugobossy]

it seems like u found out i am always here to look for updates:p
lol

[Urlyin]

are you following me okay? Hugo

[hugobossy]

so far so good:)
but where is the resistor for vmem??? :confused:

[Urlyin]

R311 in pic3 second row down from pin5 (vdd) ... just couldn't wait :D

[hugobossy]

the one with "108" ??? hard to read

my pencil is ready~~ my gpu is 590 now, i want my vmem to b 590 too~~ :D

[Urlyin]

that's the one ... go easy if you're using a stock HSF and you should do the VDDQ which is R256 in line like the VDD R311 under pin 5 second row...

[hugobossy]

mine is HIS iceq x800xt, which comes with silencer4
it should be alright:P

[Urlyin]

Hugo you can measure the VDDQ from the backside. Next to the resistor R256 looking from the top of your card down to the capacitor C110 next to R256 on the left side. It's the backside of the cap so all you see is two silver dots. Measure from the bottom dot to get your VDDQ voltage...

[hugobossy]

weird, after i modded vdd and vddq, my card cannot run stable at 590/530, where it used to be without artifacts.....
anyway, i will try to pencil mod again this afternoon
goin to sleep now~~ it's 4:46am in NZ
btw, thx alot Urlyin:)

[Urlyin]

Did you go to high ? do the vmem first, just go up to 2.08 and test the card... my memory didn't really take off until I did the VDDQ ...

[W1zzard]

images updated

[Urlyin]

images updated

I'd assumed that was the same as the VDD. If I recall the voltage didn't change when I penciled R256. I'll have to double check that one. I was able to verify voltage change on the backside of C110(right next to R256) which is one of the Caps John said to check on the front side.... Thanks for changing the pic though :)

[W1zzard]

i'm pretty sure the measurement points are right ... i measured them .. both have a different voltage

[Urlyin]

I stand corrected ... that measure point does indeed work... better than reaching down to the bottom of the board... checked it before and after VDDQ mod... voltage changes :)

[hugobossy]

wat about overcurrent mod???
is that important???
wat does it do???

[Urlyin]

Hugo did you correct your problem with the VDD and VDDQ vmod? The board has a limit for vcore voltage, once you reach it the card will shutdown. The over-current allows you to go past the limit. Which I wouldn't recommend ...

[hugobossy]

my card is running fine with 572/572 now
awesome~
thx alot:)

[Turdhat]

I am a wuss ! I want to do this so bad but I am very afraid of frying it ! I could send it to viper john I guess. I want 550/575 stable.

[Quazi]

I just want to post these to let someone who can tell me if I have taken it to far. Start voltages on the vmem was 2.09. And on the vddq it was 2.02. Then I took the card out and check the ohms reading. For the vmem resistor it read 993, and on the vddq resistor it read 767. Now these were allot more touchy when it came to the graphite than the vcore resistor was. It was hard to get them down by 30k ohms. I got close with both of them, then I would either add a little graphite, or try to take some away then it would be way off. Anyway on the vmem, I went from 993 to 962. This up my voltage for the vmem from 2.09v to 2.17. On the vddq, I went from 767 to 739. This up my voltage on the vddq from 2.02v to 2.08. Are these numbers within reason. I can now get all 600MHz out of my memory chips. I haven't checked how far the core will go now. I've been running it at 540MHz. Please let me know if these numbers are reasonable. Thanks!

[Urlyin]

Quazi... everywhere I've seen the default of 20k on both the vmem and vddq. Looks like you stayed within 8 volts... the only thing you need to watch for with the vddq and vmem is that your memory chips don't get to hot. Your not using stock HFS not sure if you have passive heat sinks on the memory but you should be okay ....

[cmberry20]

I'm still a little unsure about the pencil line 'adding' process.
Do you make a line/trace on the resistor (top) from end to end.
Or at the side? or do you make a trace on the PCD between the two ends & avoid the res totally.

How about a little video?

Along the side... starting at the soldered end to soldered end. Gently run the 2b pencil along the side of the resistor... Does that help?

[cmberry20]

Yeah.......I think... :rolleyes:
So you rub the side of the resitor with the tip of the pencil, kinda like shading in?

[Urlyin]

Shading in would be too extreme ....just sharpen your 2b pencil, run it back and forth on a piece of paper to take the sharp point down a little. Looking at pic3 in the begining of this thread. Which you should read the article if you haven't yet. Look at one of the resistors that are black with a number on it. Place your 2b pencil at the silver end (soldered) at one end, gently run it across the side of the resistor to the other silver end. It doesn't take much to reduce the resistance. A couple of swipes should do it... Are you using a multimeter?

[cmberry20]

Yeah, I've got all the kit.
Just want to me sure what I'm doing before I kill my $500 graphics card. :rolleyes:

I actually dont have bad clock speeds at the moment:
570 core & 590 mem.
Core is water cooled & only hits 34c under load. :D

[Urlyin]

Not bad clocks at all to say the least... you might just try to bump the vcore a little take it for a test run .... with those clocks your card should be performing well :)

657 core :eek: ... flippin screaming... Kids don' try this at home ... What's the GPU temp(cooling used?)? So what is it scoring on 3dmark05? Did you do both with pencil? Excellent core speed :D

I see the cooling in your sig ...

[//mAr]

i have only good watercooling at the moment, cauz i sold my phase change unit... i've done both mods with pencil ... later i have done the solder mod.
3dmark05 with 657 is 7,078. Soon i will do a TEC on the Card.
Right now my Card does 610mhz on Core without any mods... i love this card ;)
my temp is 39°C full load

[Urlyin]

I see you added another pic for overcurrent... good. Do you have a pic that covers a little farther down the board for pic3? Wanted to show the VDDQ pencil location. I have the Sapphire Pro VIVO with a blue PCB which goes nice with the blue Zalman HP. But mine never did well overclocking right from the start. I had the core up to 590 but backed it back down.
I'l try to start the VR section once I get settled in my new home and get back to normal...

[W1zzard]

how far down do you need?

[Urlyin]

Cut from the vmod VDDQ section

In the bottom left hand side you will see a hole with a dark ring around it. To the left of that hole there is a resistor in the middle of two sets of silver dots. The resistor is labeled R256, this is the one you'll need to pencil mod to increase VDDQ voltage.

I should just say to the bottom of the board is pretty much where it's at ...

Thanks :)

thank u, i hope wizzard i'll make a pic ...

did u try the vddq pencil mod?

wizzard told me also about a vdd pencil mod, but i won't try it, cauz my card is a really god one and i'm not going to kill my x800 xt pe.

[Urlyin]

Yep, W1zzard has it covered... Yes I did do the VDD and VDDQ with the pencil. Actually have done about three so far, mine, my brothers and a friends. Just the VDD didn't do much, until I did the VDDQ. Its' the core that gives you the most benefit. Which it appears your card is rockin. I only went about .08v volts on each... need to brush up my soldering skills and do the VR mods ... still in a sea of boxes though, hate moving :mad:

the one with "108" ??? hard to read

my pencil is ready~~ my gpu is 590 now, i want my vmem to b 590 too~~ :D

if u really mean vmem :eek: then im going to have to advise against u putting 590V thru ur memory!
;)

[ati.bob]

Whoa.. :eek:.. 590 Volts thru your memory chips?!? That's definately something new.. :D Gotta try it myself.. :D :D Just joking.. :D

[Urlyin]

if u really mean vmem :eek: then im going to have to advise against u putting 590V thru ur memory!
;)

If you read back and understand that he means his core and memory speed not volts... doesn't 590 volts sound tad bit high?

[ati.bob]

It's not tad bit high.. it's way high.. :D The normal voltage that came out of the wall socket are 110/240v only.. :D

[Urlyin]

It's not tad bit high.. it's way high.. :D The normal voltage that came out of the wall socket are 110/240v only.. :D

Gollu... I see you posted that your X800 is having problems. Did you get that resolved?

[GoLLuM4444]

Gollu... I see you posted that your X800 is having problems. Did you get that resolved?
nope :(
I may have to send it back to connect3d. (How) can i re-disable 4 pipes?

[Urlyin]

nope :(
I may have to send it back to connect3d. (How) can i re-disable 4 pipes?
Did you backup your orginal BIOS? If so just use the flashrom and empty BIOS, with the orginal BIOS. Download it here (http://www.techpowerup.com/articles/overclocking/vidcard/100). You'll need a pci video card to be able to flash the X800. Use the -i with flashrom and it will tell you which port the X800 is on... good luck

Hi, above all things excuse my english... im just a little french guys...

I have 2-3 questions...
Maybe there is the answer some share, but I did not find anything on this subject.
With what is used the IGPU ?
And the vddq does not bring anything to me... it is normal ?

In all the case, thanks to you, my XT EP hold the 675/675 with vgpu at 1.73v, vdd at 2.34v and vddq (even if I do not know has what that is useful) at 2.22v

bye

The IGPU is the overvolt protection. Which is used when you go to high on the GPU voltage the card will shutdown. The VDDQ is voltage throughout the board, used in conjuction wth the VDD. I hope you are using some good cooling, those are some extreme settings. I'd say at 675/675 your card is screeming... With the voltage for the Vdd at 2.34v are you using heatsinks on those flames? Your english is fine :)

[ElectriZ]

at the moment the gpu is watercooled and le ram has just ram freezer (reveltec)
in my futur configuration, le mem will be watercooled too.

thanks for your answer you're very nice :)

[Urlyin]

Np ... ElectriZ. You and //mAr definantly have me jealous... The water block seems to be the way to go... any benchmarks you can show us?

Still a good score :) His overall system maybe faster. He's running a AMD64 3500 which is on a 939 board I believe and is a fairly fast system... so if you're running a Intel P4 with a 3.2 or less than he's running faster than you...

[ElectriZ]

click on the picture you'll see a screen of CPU-Z ...
P4C 2.8@3851 mhz exacly ;)

[Urlyin]

Excellent oc for a 2.8 Northwood... I see you're pumping 1.9v to that CPU :eek: Water cooled I assume as well :) ... Still //mAr gets that stock .... Very good rig ElectriZ :D ... did you do the pencil vmod on your X800 or VR?

[ElectriZ]

the cpu is watercooled offcourse :D
I only do the pencil mod.

[Urlyin]

Did you read the steps to do the pencil vmod from this thread? If so was it easy to follow?

[ElectriZ]

yes i use this thread.
It was easy in spite of my approximate English. But I did not see how to check the tension of the iGPU. And which are the maximum value has to apply to the iGPu and vDDQ ?

[Urlyin]

Well it's it a work in progress and I'm only able to get on for short periods of time. I don't think there is a way to check the voltage for the IGPU. On the first page W1zzard lists some of the limitations at the very begining. Most of the article is written for moderation and beginners to slightly push their X800pros cards to maintain XT speeds or to increase the oc of their XT. Generally you caution against to much of an increase, most still use stock or after market air coolers which keeps them from ocing to the extreme.. I won't mention any names //mAr :)

[ElectriZ]

ok ;)
No idea about the vDDQ max ?

[Urlyin]

I don't want to quote a number that I'm not 100% sure of ... So maybe W1zzard, //mAr and possibly ViperJohn can give a max for the VDDQ?

[syl]

Absolute max voltage for VDD and VDDQ as quoted in Samsung Spec (http://www.samsung.com/Products/Semiconductor/GraphicsMemory/GDDR3SDRAM/256Mbit/K4J55323QF/ds_k4j55323qf_rev13.pdf) is 2.5V.

[ElectriZ]

thx ;)

[syl]

EZ...does not mean you should run it 24/7 at this max voltage as recommended operating voltage is only 2.0+/-0.1V.

BTW, great clocks and nice 3DMark :)

[ElectriZ]

Dont worry ;)
that just for the bench :D

[Urlyin]

Absolute max voltage for VDD and VDDQ as quoted in Samsung Spec (http://www.samsung.com/Products/Semiconductor/GraphicsMemory/GDDR3SDRAM/256Mbit/K4J55323QF/ds_k4j55323qf_rev13.pdf) is 2.5V.

Thanks Syl :) ... another note from the specs is it states the maximum clock frequency up to 700mhz

I would also believe it requires very good cooling...

[ElectriZ]

So i dont understand why i have artifacts at 680mhz for the mem :confused:
Maybe because i only set 2.34v to the vDD ?!?

[Urlyin]

Not sure why you're getting them... it could need a little more juice.. but I'd be very careful going much higher... Someone correct me if I'm wrong but I was under the belief that the VDD was not suppose to be higher than the VDDQ, but if the max is the same then does it still matter?
you're pushing that card to the extreme :D

[ElectriZ]

ho ho ... so maybe because my vDD is 2.34v and vDDQ 2.22v...

I d'like to by the first of nokytech :D
but the first one has a A64 o/c to 3ghz ... this will be difficult with my "little" 3851 p4...

[Urlyin]

EZ ... I forgot to mention that it could be in the BIOS as well... some BIOS have more aggressive timings than others... may help push you up some... The 526/573 ATI BIOS is said to have less agressive timings... just a thought :) I found that just VDD vmod didn't help much with the mem oc but once I did the VDDQ as well the memory oced much higher...

[ElectriZ]

You right, I'll try to flash the bios with better timings and lowering frequencies ;)

[ElectriZ]

Do you know where i can find any information about the timings config...
Because there are a lot of timings :eek:

[Urlyin]

Well not off hand... ATItool has memory settings but there is a warning with that... you can use it to test different CAS and latency timings...

Did you mention TechPowerup on the Nokytech forum?

[ElectriZ]

I'll try tht tonight or tomorrow

yes I even made a topic with a translation of the explanations

[Urlyin]

There are a couple of BIOS editors this one (http://www.softpedia.com/public/cat/12/1/12-1-40.shtml) recommended by Wazzledoozle which can let you view the different BIOS memory timings to get a better match for your card.. let us know what you find out ... :)

A quote from W1zzard ... "the next version fixes the timings editor + i added individual data files for r300,350,360,420 and rv350,360,370,380,410

in reply to dominik's email: i'm pretty confident you cant damage up your card by playing with the timings .. not 100% sure .. thats why the disclaimer is there."

The other editor is Rabit 1.5 Bios Editor ....

[ElectriZ]

I have rabit (the 1.6 hotfix)
above flash the bios i'll test with atitool

[syl]

Thanks Syl :) ... another note from the specs is it states the maximum clock frequency up to 700mhz

I would also believe it requires very good cooling...

NP ;) Please note the maximum frequency of 700mhz specified is in reference to the GC-14 (14ns) version. Maximum frequency for the GC-16 (16ns) memory used in most VIVO's, XT's and all XTPE's is rated at 600mhz.

[Urlyin]

I stand corrected :rolleyes: thanks again Syl... was trying to brush through it before I ran out the door to vote and off to work ... :)

yes i seen that ...

you're pushing that card to the extreme :D
I'm confused as well...
According to Samsung: "Under all conditions, VDDQ must be less than or equal to VDD"

However, W1zzard and other experts have stated that VDDQ should measure higher than VDD on the X800's - and this is indeed the case on my MSI Pro VIVO. This would also mean ATI's reference design has the Samsung memory running out-of-spec :confused: :confused: :confused:

My conclusion was you wouldn't want you memory running at a higher voltage than what you were trying to push through the board... but by default before vmod my VDD was 2.00v and the VDDQ was 2.08v, so I concluded that what I had read and what the meter said was correct... hmmm

[Urlyin]

yes i seen that ...
my GC is at 680mhz at the moment :D
You know EZ with a core speed of 680mhz you should be able to take the top X800 spot on the Doom3 benchmark here (http://www.doom3benchmarks.com/) :D

[ElectriZ]

hummmm :D
i think tomorrow i'll setup doom 3...

edit : 681/681 = 7030 3dmark03 :D
re-edit : 684/681 = 7033 :(
i think that's the max for my little sapphire

[Mussels]

as urylin has instructed me via PM, i pencil modded my card.
i have the ATI silencer 4, and dont want to solder, so its impossible for me to measure voltages.

VGPU went down by 30 ohms, and gained me from 534/555 to 567/567.
card doesnt go above 60C load. (although my case has good airflow)

VDD and VDDQ i lowered both 24 ohms. ZERO change in OC potential. i did and redid this repeatadly, and never one change.

since the samsung and the ATI specs seem to differ, could someone with the resistor mod please tell us which way works best? higher VDD or higher VDDQ? and at what resistance you are running at?

after adding an OCZ enhanced power lead, i got more OC too... all the way from 567/567 to 571/571... what the hell, im sure for stock cards without volt mods it'd do better.

OHM readings for my card, pre and post mod are following.

VGPU -> reduced 30 ohms (lost the paper with numbers... dammit)
IGPU unchanged.

VDD 937 ohms -> 913 Ohms
VDDQ 760 Ohms -> 736 ohms


oh and for the n00bs to this (as i am) please make sure to keep the black end of your multimeter to the one end... i use the bottom.
if you swap the leads over, you will get a different reading, and mess the mod right up....

Mussels if you lowered VDD and VDDQ equally then it should be fine. But not being able to check the voltage change does hamper you a bit. That verifies you are doing the right resistor. I also did those several times to verify that they were correct. I was able to reach 600mhz on mem after the vmod and barely 573 before. I raised my VDD to 2.15 from 2.00 and the VDDQ was 2.08 to 2.22. I don't have my starting ohm numbers in front of me. But before you started you said you only wanted to stablilize it at XT speeds. Well that is what you have an then some... still a decent oc. Enjoy the new speed :D

[Urlyin]

Hey EZ... I see on Nokytech that Nalioutz has a 3.4 running at 4.1 and his X800 is at 609/582 but he is only scoring 5810 on 3dmark05 :confused: I'm getting higher than that with a 3.0e at 3.8 w/ x800 550/580 ... I was just curious ...

[Goldlocke]

Will the IGPU mod help with the decrease of VGPU under load?
My VGPU set to 1,80V @ idle drops to ~ 1,69V under load.
When VGPU is set to 1,70V it stays there under load!
So I guess, OCP limits VGPU output under load, right?

So solder a 250kOhm VR on each side of R1596 will help?

thx!

[ElectriZ]

Its because its a w800 pro and he dont active the 4 pipelines...

[Urlyin]

That would explain it :)

[ElectriZ]

;)

[Goldlocke]

Will the OCP mod remove the drop of VGPU under load? see my post above.

If not, why is that drop? From 1,83V to 1,73V under load.
thx! :)

[Urlyin]

If not, why is that drop? From 1,83V to 1,73V under load.
thx! :)
The OCP is for over current protection which would shut the card down. As for the power drop you may need to turn the VDDQ in the BIOS up or your power supply my not be up to snuff ...

That's an extreme number to push through .... no stock air cooling there

Sorry I see this was your original post... I don't believe that the IGPU (OCP) will aid your droop. Try to make sure nothing else is on the power lead that's plugged into the Video card. If you can take as much load off the PSU as you can to test if tha'ts the issue. The BIOS VDDQ may help a little but, don't think it'll solve it. The VDDQ vmod is for the memory buffers and a little push there may help... I'm assuming you did the VR vmod on the GPU... could it be the type of varible resistor you used?

[Goldlocke]

As to the PSU. I use OCZ Powerstream 520 with the dedicated coated Powerline to the vidcard.
It could be the VR type - yes. At the moment I use a cheap one. I'll try a cermet type tomorrow.

What VDDQ do you mean with "bios VDDQ". I did VGPU mod, OCP mod, VDDR and VDDQ mod yet.

[Urlyin]

In most MOBO BIOS(CMOS) settings they have AGP VDDQ voltage. I can set mine on my ASUS P4P800-E from 1.50v to 1.80v... used mostly to stablize overclocking of the CPU. It is said that higher voltage on the AGP VDDQ can shorten the life of your video card, but in your case I don't think that'll be an issue... it may help, what MOBO do you have ?

[ElectriZ]

The Vagp setting of the mobo is not used with the the card like x800...
the have an other power source ... the molex.
Change the vagp will not help for overclocking on x800.
That's help for smallest card like 9550, 9200, fx5200...

[Goldlocke]

I upped the 5V rail of my PSU to 5.5V. guess what?

Now the VGPU stays where it should be under load! :)
(upping the 12V rail didn't help).

[Urlyin]

Nice OCZ PSU :) ... good info to know ... I would have guessed 3v rail :rolleyes:

Goldlocke... what are the core\mem speeds?

Thanks EZ ... your right the Vagp doen't help much on the X800... not realizing the OCZ PSU had dials for votage rails. It was just a suggestion... :)

[Goldlocke]

Goldlocke... what are the core\mem speeds? 620/630 so far. my card is no good overclocker. :(

VGPU ... 1.83V
VDDR ... 2.20V
VDDQ ... 2.24V

[ElectriZ]

what the card do if you go over that frequencies ?
freeze or artifacts ?

[Urlyin]

Ez... was looking for you on the Doom3Benchmark ... :)

[richieroro]

Just wanted to make sure... for the Vdd pencil mod which one is R311 in pic 3? Is it the one with '153' or the one with '108'? From your description it sounds like the '108' but I've seen on VR-Zone (http://www.vrforums.com/showpost.php?p=517135&postcount=7) that it's the '153'... although there were many people on that thread that said it wouldn't work for them...

So which one is it exactly? Also, could you clarify one more thing... when you measure the resistance, do you measure the resistance across the resistor or against ground? Thanks!

In pic3 it's the one above the label r311 and yes it does look like 108. I measured from across the resistor, but I do believe you can do it both ways. I would also suggest you do the VDDQ with the VDD vmod. My memory didn't oc well till I did the VDDQ as well. Check W1zzards safe voltages with cooling used at the top of the first page.

I followed your guide and upped my VGPU to 1.55V, the VDD to 2.40V and the VDDQ to 2.40V as well. The problem is now, that I get some artefacts in 3DMark03 mainly in game 3 and 4 even if I lower the VDD-frequency to 540 MHz where I didn´t have any artefacts before the MOD. So what´s the problem now? Could it be, that 2.40V is too high and that that´s causing the artefacts?
I´m using the ATI-Silencer for my X800 Pro btw.

Nagybalfaz_b ... I would consider that you have gone a little to high for your card. If you followed the guide it says take your time, in other words don't go for the max right from the start. Take your VDD down to around 2.08v-2.10v and back down the VDDQ down to 2.16v-2.18. Verify that your card is working with those settings and work your way up.... take your time :D

You guys are insane.....isnt the x800xt fast enough? lol

anyways, i am inspired by all of your friendlyness and camraderie in squeezing the absolute most out of your top-dollar systems. keep up the good work!

does anyone know of a thread for modding 6800gts? i will be getting one soon, upgrading from my trusty tyan 9800pro. also getting a koolance and im gonna see how far my 2.6c will go, its at 3.2 on an SP-94 now. also, anyone know if the OCZ ram booster has issues with an IC7-MAX3? i have read about this board having inconsistent Vtt at Vcc higher than 2.8, but i dont know if the ram booster would affect this.

Thanks in advance for all your helpful advice!

[DiDiSeVEN]

Urlyin, thx! I did all mod's with Vr and they working great except the Vddq , I sold like the pic in the first page, but when I turn the Vr the voltage have no change, I'm reading 2.183v now. What's the problem?

[Urlyin]

What was the default reading before you added the VR? The 2.18 is already above the default of 2.08 which is what I've seen for the VDDQ ... The VDDQ is the soldered to the same pins as the VDD 5 and 7 ... a 20k VR should give you about .08 to .10 volts ... which looks like what you have at 2.18 ...

[DiDiSeVeN]

I did correct at the pins 5 and 7.And the default voltage was about 2.08v and now 2.18v. But my question is If i turn the screw of the Vr i don't more in increase of vddq like vdd and vgpu?

If I turn the screw of the VR I don't suppose to have more voltage in Vddq like Vdd and vgpu?

THX

[Urlyin]

Didi ... yes it should be adjustable. Some VR have more turns than others. What size is the VR a 20k? does it decrease? 2.18 is about all your going to get out of a 20k VR and is about the max your going to want to run the VDDQ at ... are you using the same legs as the others? it may be a bum VR or the screw is stripped...

[DiDiSeVeN]

Thx Urlyin, I changed my vr and now is everything allright! :D

Rad system Joe ... be a member and register. Thanks go to W1zzard ... and if you're going to mod the mem do the VDDQ as well ...

yes MANY thanks to W1zzard, but many thanks to YOU for writing it like it was the first time someone picked up a MM (which was basically my situation :o )

did ALL mods and raised my Vcore to 1.57. (JUST did it) and my GPU OC (for now) went from 615 to 645 :D
could probly still go higher but ill just enjoy THIS for a while.

and 7168 (http://service.futuremark.com/compare?3dm05=474819) in 05, 15,729 (http://service.futuremark.com/compare?2k3=3581174) in 03, and 37,372 (http://service.futuremark.com/compare?2k1=8365118) in 01 :D

85,000 in aQuaM? (hehe) try 96,000+ :eek:

Nice core on the card ... and the maze4 I'm sure has something to do with it... 7165 in 05 is crankin... looks like 85,000 is in reach with Aquamark as well .... nice job Joe :cool:

I've been following this forum for a while and I did the VR MOD on the VGPU, VDD and VDDQ. My card is a retail x800 xt pt by ati. I see you guys getting these crazy high 3dmarks in 05 yet with my card OC'd I hardly see any increase at all. I have a P4 2.4 running at 3.3 with a 276 FSB 1:1 with the memory, which I thought was pretty good. My core at 630 and mem at 590 I only get around 6300 3Dmarks which is what I was getting at 573/573 before the mods. What gives?! Also, my card is watercooled and maxes at about 38C, what would the be max safe voltage for the core? I have OCZ ramsinks on the ram and it does get pretty toasty, I have it at 2.15 and the VDDQ at 2.20. I can run the ram now at around 600 or 610 (I think) but have to test more. Something that is happening is I do a 3Dmark and in the forest benchmark the screen just goes blank and I have to restart my PC. I get no artifacts before that, it just dies. Is my voltage possibly suffering the droop as I've seen others post about? I also have the OCZ 520 PSU but I haven't cranked my 5V line up yet, it is about 5 right now though. Thanks for the help guys, this thread has helped me a ton!

Jigg it's a combination of things that results in those high scores... What's the Vcore at now?
If you read the article it does mention not to get caught up in what someone else is scoring ... good way to toast your card .... what are you running the memory at 1:1 or 5:4 ? What does it score in Sandra memtest ? CPU arthmatic ? Some of those synethedic benchmarks will help us tell where some of the bottle necks are ... it may not be the card but a 6300 isn't that bad ...

[Jiggaman2576]

I know I will never reach the speeds of these AMD 64 speed guys, that is until I get one for myself! My current memory is 276 FSB 1:1 with the CPU and I get a bandwidth of 6200 MB/s in Sisoft. My CPU performs like a 3.4 P4 according to Sisoft. The problem that I am trying to convay is, I have overclocked my video card quite high compared to stock, and my scores are EXACTLY the same as they were without any overclocking. I'm sure all of you are not overclocking your cards just because, and the reason I'm doing it was for better fps in games, which I am also not seeing. I play all my games at 16X12 with 16XAF and 2X-4X AA which I am sure would benifit from having an overclocked card, yet I dont see any of those kinds of gains. I am guessing that something in windows is holding me back, a bad registry setting or something. I've gone through a services tweak that I found on the web recently, and basically everything that is not required for my system to run is turned off, I have almost nothing running in the background while testing. Now here is one thing that I haven't tried yet but thought it shouldn't matter much anyway. I have a video capture card that is using the same IRQ as my X800, could this indeed be limiting the throughput of my system? I hardly use the capture card as I have switched to sat tv and dont have a tuner by my computer, now I just play xbox on it at lan parties and even that is few and far between. Other things I haven't tried would be going back to previous drivers. Also, my buddy of mine gets 150fps + looking at the sky in HL2, yes I know that's not a big deal because there isn't anything to render, but when I look at the sky with mine it caps it at 84 and will never go above it. Is this something wrong with the game or drivers or what?! Thanks again guys, and if I need to give you anymore info let me know.

Jigg ... is your buddy using the same settings as you, is he running close to the same setup? ... 1600x1200 16af 4xaa on Halflife2 is on the edge... I'd pull the other card and try to clean out the drivers with driverclean3 or something like it. I haven't tried the 4.12 cats yet but thought the 4.11 did well... 20mhz more isn't going to buy you much as far as FBS go... are you running a stock HSF on the video card? Use ATItool to max out the fan to 100% If you get lock ups it because the oc is to high ... we can work on it ... anyone else have any suggestions? I'm sure Jigg would welcome them ...

[Jiggaman2576]

The video card is watercooled, never goes about 40C and idles at about 29-30C. My buddy and I are indeed running the same cards with same settings, even the same bios. I did a driver clean lastnight, and we aren't talking 20 mhz, we are talking from stock to 630 which is 110 mhz on the core, and 20-30 on the memory. The other thing is he is running an AMD 2500+ not the 64 bit but the older ones. He is overclocked on that also, and both have watercooled CPU's. My FSB is about 56 mhz faster, and my memory bandwidth is about double what his is. My system in all respects is faster then his, and his beats mine in benches and in real world gaming. I also have a new problem which may have already been answered in this forum. I have my Core voltage at 1.7 not 1.75 as I had stated earlier. When I run 3dmark 05 or anything 3d for that matter, I can watch the voltage drop down to 1.64, and at a certain point it drops to 0, the monitor goes black, and I have to completely power off and then back on again for the card to come back. I'm assuming that the overvolting is the problem and I may have to tweak mine. I have the OCZ 520 powerstream and my 5V rail is at 5.24 according to mbm, I am going to raise it to 5.5 tonight and test again as I saw someone else did that and it fixed his problem. I just want to know, what else could it be? Also like to add, when I have the memory at 610 my benches, before it shuts down that is, seem to be a few fps higher then they were before, so my core was probably just choking for data from the memory as viper john had pointed out, so now I just have to get it so it doesn't shut down and I'll be happy. Oh yeah, ATI tool gets to 666 on the core before it freezes the system, would running at 645 or 650 be a safe bet below what atitool can reach? Thanks again Urlyin.

I'm trying to read your post at work and just kinda skip threw them ... but you're doing well on your own. First I have nothing but respect for ViperJohn and W1zzard. But you hit the nail on the head when you said 1.70 and it blacks out... you haven't done the IGPU mod or Overvoltage protection mod yet ? .... John has pointed out to me the importance of memory when OCing as well ... Don't base your oc on ATItool only... I thought ATITool would be lower than what I could actually run games at... so do a combination of benchmarks, I use Benchem All to run Frycry, 3dmark03, 3dmark01 one right after another twice on it bench. A good way to test the CPU oc as well... if you have a dialog open with ViperJohn continue to heed his advise ... busy guy... But the 20mhz came from the 570/570 to 600mhz you stated so again I must not have read the post entirely ... But as you know every card oc's differently and I'm looking at the oc Joe Camel has and his GPU is at 1.57v and his is hitting 645mhz or more. I was hitting 600mhz at 1.50v ... Before you crank up the juice on the PSU, you might want to try dropping the volts on the GPU from 1.70 to 1.60 - 1.65 ... at those volts you should still be able to hit 640mhz on the core.

Anytime Jigg ... hope this is helping you work things out :D

Edit ... you have the Overvolt protection and need to tweak it ... what size VR did you use?

[Jiggaman2576]

I didn't do the overvolt protection as I thought that wouldn't kick in until like 1.8 or so. I can have it added though, and what size VR would I need? I used the recommended sizes that were in the guide at the beginning of this thread and they have worked wonderfully. I'll take the core voltage down to 1.65 tonight. Also, is it a big deal to see it go from 1.7V down to 1.64 while benchmarking? I'm guessing that is normal but maybe I just am having some droop from my molex connector. I did not use the supplied VGA from the OCZ PSU mainly because I dont know if I can get it to reach, maybe that would be another thing for me to try tonight if I can get it to reach. I should post a picture or 2 of my system, it's a server minicube with all the drives and PSU on one side and all the watercooling and boards and stuff on the other, so cable lengths can be a bit of a problem sometimes for me. I'll try to post back some results tonight or tomorrow if I can.

PS: If you want to talk to me directly my AIM SN is the same as the name I have been using on this thread.

I hear different numbers on where the OCP kicks in. But your card is displaying those symptoms. The VR shown by W1zzard is a 250k VR. I know one member says he upped the 5v rail but I shot off an email to ViperJohn and he mentioned that lowering the 5v rail has helped in the droop that you are seeing in some cases. He mentions that a normal loaded Vcore droop is anywhere from .010 to .030 volts. So you're dropping .03 below normal droops given that's for default voltage settings. He explains the principals and basically the card tries to compensate and limits the current to the GPU.

[Joe Camel]

these are the words that "guided" me to the Vcore i stopped @ :cool: :



...ViperJohn.... Since then I have developed a Vcore Droop mod as well to keep the cards active
droop circuit from turning into an active current limiter when the core loads up with Vcore over
about 1.580 volts at the desktop.


ive been in contact with him for few months now (till i could get my hands on a "reasonably" priced card)

i DO plan on having him hard mod this card, but just HAD to try this out :rolleyes:

He tells you like it is and them some ... Great Guy who has probably helped a many a modder... I can speak from experience... I should be getting a card back from him shortly... to bad he doesn't make case badges ... hehe ... he does know his ATI cards... not afraid to say he makes me look like a rookie... W1zzard is another one to get to know ... both willing to help :D

[Joe Camel]

so do pencil mods degrade? (no, i havent moved/removed the electrical tape i placed over the mod points)

since benching @ those WONDERFUL speeds, i now can not even run a screen saver @ > 660/600... :(


658/585 is about where i can bench now... :confused:

Hi everybody :)

Personally, I have never done any hard-mods before, though I have done the Pro VIVO @ XT PE, and I am running speeds of 540/580 artifacs-free (I can bench at 620 on mem, but with artifacs) Anything above these speeds, there is artifacts, and the machine freezes... Because I have, as mentioned, never done a hard-mod, I wondered if it was possible if anyone could perhaps take some pictures while actually doing it, and even better, filming it... I have all the equiptment needed, I think. I am a bit cunfused regarding the guide though, what on earth is a VR? and what is it good for? do I have do have them?

I am from Norway, so I am not too familiar with all of the expressions and such, please excuse my bad english too :)

The VR (Varible resistor or trim pot) section isn't complete yet... if you need to ask what a VR is then you may want to contact someone who can mod the card for you, there is a name in the article. You can try the pencil mod...

[adt]

Well, its not really possible for me to send my card to anyone, but if the VR stuff has nothing to do with the pencil mod, then it doesn't really matter :) How about the voltages with the pencil mod, will I be able to give the core 1,7 volts?

It does matter and it would be hard to get the card to 1.7 with the pencil mod ... the pencil mod is okay for low to medium overvolt but not 1.7v ....

[adt]

OK, then I guess I did understand the instructions... And because I don't even have a general idea when it comes to electronics, I think the pencil mod is more than enough for me... But will it make any difference, and is it easy to remove all traces If I regret I ever did the mod?

No, you do not need to do either...

[rlhc17]

do u think that it is better to do some vddq mod to stablize both Vcore & Vmemory voltage ?

:confused:

[Urlyin]

:confused:

You really only need to do the VDDQ if you are doing VDD ....

[Rammsteiner]

Hello,
Im new to this site, I was watching the mods whole the time lol. And after long thinking I decided to do it. Got my Vcore upto 1,45, VDD 2,12 and VDDQ 2,22(maybe the VDDQ should be a little lower?).

I screwed my case open, build a stupid frame of LEGO(its finally good for something lmao) and laid two fans in it. With a pretty 'hot' room(20/25 degrees), case open, and these two fans it wont go over the 65 degrees at 540MHz. I did the Pipelines mod(with BIOS, have a ViVo) so I know I dont should expect much more from core, its running also at 555Mhz, but the problem now is the memory....

As you guys can see some lines above, the Volts are pretty 'normal'(ok, can go higher lol), the degrees are pretty low but I just cant get my memory without artifacts at 600Mhz...!?

Should i do the IGPU and higher the VGPU? Or sometihing else? Right now its pretty cold in my room(10 degrees), window open, case open, all fans busy, my memory isnt getting much hotter than 20 degrees... What do you guys think to do? Ill do a 'mod project' in a few months, so watercooling will be there too probably, but my card is already pretty good cooled...

Thx in advance

[Urlyin]

Ram,

Lower the VDDQ to around 2.18v and raise the VDD to 2.15v. Sometimes it's just the card... do you have ramsinks on the mem? You can take the Vcore up a tad to 1.48v to 1.50v until you get some other cooling options...

[Rammsteiner]

Hello, thx for your reply.

I dont have any RAMsinks on the memory yet. Ive ordered with a friend of mine two Zalman VF700Cu's(he one, I one). But hes sick at the moment(as ussual, lots of tests onm school lmao). But anyway, Ill go to him soon to get the cooler. I heard much positve things about it.

Nut hte memory isnt anyway getting hotter than 20/25 degrees at the moment(as said before, its kinda cold in my room). But Ill try to upper the VDD and lower the VDDQ... OMG, I really hate it when you added just a bit too much graphite... lol

Thx, Ill post the results

Bob

PS: Im dutch, so please dont care about my English lol

[Rammsteiner]

Hello,

I did what you said, but didnt matter... I even added 2,2V's to the VDD!!!(and VDDQ 2,22V, I think VDDQ is something the same as IGPU is for the VGPU?). Well, anyway, after getting set up, thinking to just give it the full 2,45V's(what needs active + passive I read, but I always never listen when it isnt working lol) I took the other way, a for me smarter way...

Normal, didnt maater how much VDD and VDDQ, my memory at 600Mhz began artifacting within a minute(if I wa slucky, normally after 10 seconds). So the smarter way was to get the VDD and VDDQ mods away, to yel to them and added(what you said) 1,52V's to my Vcore... And guess what!?!?!? Its running the core on stock and the mem on 600Mhz already without artifacting for 10 minutes... :confused:

So, Im reall confused about this... Why is the VDD and VDDQ mod needed then!? And can someone give me a reason why the VDD and VDDQ mods didnt worked and the Vcore was enough???

But anyway, thx for your help :D

Ram ... every card OCs differently some the core ocs well but not the memory or visa versa. The VDD is for the memory and VDDQ is for the voltage to the memory Buffers. If you just did the .08v to the mem and the .08v to the VDDQ it should have put you around 2.08v for the mem and 2.16v for VDDQ. It's worked for me on several cards some up 600mhz and one or so it didn't help. Some cards like it some don't and in your case you said it wouldn't before the mod at stock then after the mod it worked stock is that correct? Did you change the BIOS? in some of the BIOS the memory has a less aggressive memory timing which may have been what happened to you. In any case some of it is trail and error to find what works best for your card. Remember to take your time and don't over do it... you can get an nice oc even with the pencil mod ... :D

NOOOO...

I dont know what happened, but my screen was gone out, I thought, strange, maybe the IGPU? When I was in my case I smelled the smell of PCB :mad: :( ... Man, this is bad... It wouldnt start up anymore with the VGA in it. So I thought(maybe too late) after two hours, maybe Ive to lay it in the freezer. It was in the freezer for 10/11 hours. I made it dry(iof condence) and set it in the PC again, but still nothing. Ive a EP-8KDA3+ motherboard with a P80P statusLED(postcodes). I only dont kmnow what BIOS i have, but the LED says 25 when Im starting up with the VGA. When I 'studied' the card a bit I noticed some 'burn' spots on a place I was kinda surprised, by the MOLEX connector!?!?!? It was kinda smelly with the VGPU transistor, but I couldnt see anything strange(I know how a 'burned' transistor looks like, destroyed a 10Ohm transistor on school with 12V's lol). But anyway, the burnspots are around the MOLEX connector...

1. What does the transistors have to deal with the MOLEX connector?
2. What actually did happened?
3. Is it my fault that my car dis destroyed now or is it destroyed by the PSU?(Ive the Antec True Control 550Watt, I didnt modded my PSU by making it more V's, onmly with the controller, but that isnt really a mod/dangerous or whatever)...

So what do Ive to do now? Is my card really destroyed now?(which i dont hope because my parents dont allow me to buy a new one :( ). And as asked before, was it myfault or is it something else? And what should I do now?(what should you do if it happened?). If it was a transistor I dont think its a very big problem because a friend of my is good with soldering, so he can set another transistor on it, but the burnspots were by the MOLEX connector...)

Please help me out!

Thx in advance,

Is it possible to perform this pencil mod on a ASUS X/800 XT PCI-E card?

I have looked extensivley for the R1597 resistor but my card has the R1598, 1596, and 1590, among many others too. I can't seem to locate the right resistor as this ASUS card is a bit different than stock
'made by ATi" exact cards. (ASUS did their own thing I guess)

If someone could just tell me all the resistors I need and a gerneral idea of where they might be it would really help me.

Stock the card does 564 core, and 540 ram. I want 610 core, 600 ram.

Thx for anyone's help. Sorry about not registering yet, have not got around to it but plan on it.

Ok I found where it is but it is not like in the pictures. Bassically (sure there is a technical term for it) all that is in the spot of the R1597 cap. is 2 metal squares, sparated about a half mm apart. Still taking up the same space. I tried to pencil these in but it did not work. I also found the other connectos and the ram mataches fine. I am gona give it another go later tommarow but it would be nice if someone knew that mabbe the R1597 is not what i need to fill in, its instead the R1592 or something.

O I got the volt meter but am not sure where to test for voltages on this card...again not the same as the guide on page 1. This would help too.

O and sorry about the double post it would not let me EDIT b/c I am not a registered user or something like that. (some enter username thing)

hi every one i have a x800pro watercooled buy waterchill and have a gpu temp of around 28-34 degees, underload running at 550 . i want to do this mod i will be doing it pencil way. can anyone tell me what kind of gpu speed i may go to.....also has any that live in uk found the resistors needed to do the job... have tryed lots of shops <eg> maplins......
many many thanks to all you boys who figger this s++t out......ohh sorry im using ray adams tray tools....thanks

Hi urylin i did the pencil mod on my msi x800xt pe i did the vgpu mod and the vddq mod, i did,nt do the vdd mod because i,ve no cooling on my memory i have a coolviva cooler with heat pipe i upped my core from 1.39 to 1.51 and my vddq from 2.08 to 2.16 and i can now oc my core to 575mhz before the mod i could only go to 526mhz but when i run any benchmarks i see no improvement in score over the lower clock speed.I,ve run 3d mark 01,03 and 05 with no improvement in any of them,any help would be greatley appreciated.Thanks in advance.

[dixsey]

Did you go to high ? do the vmem first, just go up to 2.08 and test the card... my memory didn't really take off until I did the VDDQ ...
Hi urylin i,m a newbie to all this but i followed your instructions above for the vmods on my x800xt,excellent stuff i was able to do the vcore,vddq and the mem vmod and they all worked but i,m still only able to clock my core to 550mhz and mem to 570mhz(from default of 520/560) my voltages are as follow,s, core from 1.39v to 1.51v, mem from 2.00v to 2.11v and vddq from 2.08v to 2.15v i also installed a coolermaster coolviva vga cooler to my card, are these clocks about right for the new voltages i,m running with,also the benchmark score,s have,nt improved that much.Any help would be much appreciated thanks in advance.

Dixsey.. each card will react deferrently to a rise in voltage. Some take off and some just so so. What type of system is it running on, it could be that is the bottleneck.

Hey Urlyin, Ive a new card :D , and that one also enables 16 pipelines. But now Ive a strang eproblem here. I did the mod again(only Vcore) from 419Ohm to 394Ohm, so thats pretty good. My core went from 475Mhz to 550Mhz(with the 16 pipelines). Its AROUND 1,48V. Ive also the new Zalman cooler(VF700Cu with RAM heat sinks). So should I try some higher voltages like 1,55V to 1,6V? But the problem is that I see some strange blue things(looks like artifacts) in the sky with the first test in 3DMark2001se. I first thought it was maybe a bug, but I ran 3DMark2005FE and the first test had them also... My memory was running at 600Mhz, and I had for an hour(after that I just stoppped) NO artifacts, but in the 3DMarks I have. When I lower the MHz for the memory to 560Mhz its doing allright. But what should I do now? doing also the VDDQ and VDD mod? I would like to do as less as possible mods on my VGA to prevent it from frying again lmao. Is the VDDQ mod needed?

Thx in advance

Good to hear Ramm :D ... I'd go with what you have right now and just play. Remember you weren't really sure what killed the last one. We didn't totally rule out the PSU, take it slow. Run the card to make sure the new one is fine ...

Dixsey... isn't that 3.06 running at 800mhz? If so the PC2700 mem is slowing you down some... and if you're runniing mixed sizes it'll cause issues as well, run either 2@256 or 2@512, unless of course you're running the mem at 5:4 instead of 1:1 ... try to bump up to 1.56v -1.58v on the VGPU and game from there to see where your at ...

Though I want to do some Vmods soon lol, I want to try 600/600, do you know what Voltages I probably need for that? Thx in advance

No its only running at 533mhz not sure what you mean about the ram but i,ve 2x512mb in slot 1 and 3 and 2x256mb in slot 2 and 4, i,ll raise the voltage on the vgpu, thanks.

Could someone pleeaaase answer that 3DMark question of a few posts back? Thx, I really want to know what with that because my memory HAVE to run at least 600Mhz guaranteed!? Its both sides 1,6ns... I dont get it, Ill also rise my Vcore to 1,6V I think.... Ive a Zalman VF700Cu, that would work fine lolol

[Rammsteiner]

? OK, Im getting so frickin mad!? I did the mods, my Vcore to 1,55V, its running fine between 550 and 560Mhz, better OC than my previous card :D Thats fine. BUT I WANT AT LEAST MY MEMORY AT 600MHz! VDD is like 2,06V and VDDQ 2,19V. But something is strange going on here. I ran Atitool 1,5 hours(this time the 23.0 because I thought that the 24.1 beta has a little bug, sorry for that, but it hasnt one. Great job W1zzard :D )!!! at 550/600. NO ERRORS! I want to bench it still shows me the same bluey thingies in the sky. I thought maybe its because the new drivers. So I thougt maybe the drivers are already patched, so I download....I discover that I didnt have the new drivers :confused: ... well, peeps make faults so I reinstalled every thing thats dealing with Ati. So a clean new driver setup. Everything ok. I start up 3DMark2001se again and still those mf blue things... :mad: . WHATS GOING ON HERE!? Should I just say f-u to the 3DMarks and ignore it? I noticed the bluey things are exactly the same in both 3DMark2001se and 3DMark2005FE... Thats pretty strange... As I already said Ive some monster cooling on the card, so thats not the problem here... Im so afrait to mess up my card again so I hoped that the Vcore was enough, but I NEED TO DO THE MODS WHOLE THE TIME CAUSE I THINK IT's GETTING TOO LESS V's, but its not because Atitool ran fine without errors... Or are there some great STRANGE bugs in 3DMark? Ill try to lower my CPU OC because that one isnt very stable(few games and SuperPI 32M, it crashes already after 2 minutes in Prime95 :cool: lol). Any help is appreciated, thx in advance

hi my card is watercooled and should take a good clock...
the ram has some heat sinks on them will this let me give the ram a better clock.....
many thanks gee...

[Rammsteiner]

OKay, its not because of my OC, and it also looks like the bluey things only appear at the same places... Could be my monitor(hopefully, OTOH, in 3DMark2001SE I can also see some textures or so :confused: . Are th 16 pipelines maybe broken? I dont think so because it looks like to happen when I raise the mem mhz above 560-570... I have now VDD 1,12V and VDDQ 1,19V... I dont get it? Is my memeory broken or so? This is so weird :mad: I WANT HIGHER OCs! my previous card also didnt likes it to run higher than 570, but that one showed artifacts in Atitool, this one isnt...

Ramm.. you need to slow down bud... it may be that the cards memory doesn't oc well. Try 2.15 for the VDD and try to keep the VDDQ around .03v -.05v above the VDD 2.18v -2.20v . Did you say that you changed the stock HSF? Make sure it seated well and you did a good paste job...

Hello Urlyin,

I did also noticed the memory isnt that great lol. But its more or less running 580/590Mhz. But I discovered a strange thing. I highered the core more and more to run sync with the memory, but after every 10Mhz closer my 3DMark2001se lowered? Now I made some calculations, and it looks like(well, for me, maybe some others would like to try it to confess it?) when the core/mem ratio is 0,9(so the core is lower than the memory) the card runs the best. I ran 560/580, that one was slower than 540/590. And maybe Im right, watch the difference between each card from Ati(the X8xx series). The Pro is 475/450, also more or less the slowest(ok, the non-pro is slower, but that one isnt counting here lol). than the XT has 500/500, so the memory made a step of 50Mhz here!, But the core only 25Mhz, so that should be much faster. XT PE is 520/560. memory made another jump af 60MHz, the core only 20. 850XT is 525/575. Memory made a jump of 15Mhz, core only 5MHz. 850XT PE is 540/590, memory made a jump of 15, this time the core did too. It looks like to me that a ratio AROUND 0,9 is the best performance? Why should Ati take these speeds anyway if Im false? So please try it :D

Ill higher the VDD to 1,16V, the VDDQ will be like this(1,19V) or 1,2V. My core is running now 16 pipelines. But Ive a little question, when I reduce the resistance of a resistor(no matter what, VDD, VDDQ or VGPU), are there ANY other chips/things that are getting hotter except for the GPU, and memery?(so I know where Ive to watch for :D ;) ). If so Ill try to get 1,65Vcore(and I think my new cooler is installed almost perfectly, I almost destroyed my screwdriwer because I turned it too hard lol). The cor eis only getting 50C under full load, so thats ok I guess?), but anyway, 1,65V should make it possible to run around 580MHz stable. Than I want my memory to run at 0,9 ratio, so that should be 650Mhz :eek: :rolleyes: ...
