Post Pics of your X8?0 Vmods

[Urlyin]

We've seen some really nice pics posted by some members of their vmods on X8?0 cards.
So I created this thread to have a vmod collection for those who wish to post pics. A link will be added in the X800 / Non Pro / XL / X850 Vmod Article... link (http://www.techpowerup.com/articles/overclocking/voltmods/112)

I modded my X800XL from Club3D in the best way I could.

On the first pic you see the voltmod mounted on the card

http://www.xs4all.nl/~eikelman/temp/atix800xl/6mounted.jpg

And on the second pic you see the modification to the mod which made the mod switchable while working.

ViperJohn Modded Asus X850-XT

Bios 113-A47401-101 dated 11/08/04 Shows up as X850-XT PE with stock clocks 540/590

Vcore = 1.680 @ Windows Desktop
Vcore = 1.660 @ Loaded Max Droop
Vdd = 2.300
Vddq = 2.250

Not much to actually see on this card. Mod is also 100% reversable. It has a Custom Danger Den WB w/extender, Temp Sensor directly on GPU w/Front Panel LCD Readout. John's NTSB with his Watercooling KIT (Ram heatsinks with Active Coolers).

Last benchmark produced 7287 (http://service.futuremark.com/compare?3dm05=890019) 3DMark05. Just got the card so Im still tweaking.

[wtf8269]

And of course Morlak takes the cake. :p He doesn't have any cool stickers though!

[Morlak]

Yeah even the stickers that were on the card (P/N, S/N, etc) were heated off by John and placed in a plastic bag. I have pics of the card so if we decide to go back to the stock form in case of a RMA or something we can put the stickers back in the right place. John does that so the card can be returned to stock, and he doesn't muck the stickers up. Very thoughtful and professional. I guess I could take a pic of my sticker bag. Wanna see that? just kidding. nobody wants to see that Im sure.

True, True. Hey go to my pics page, see the heatsinks on the X850? Homemade using mr. hacksaw. not exactly soldering iron type mod but hey... I have always liked the way John's cards looked, and wanted one; Big deal.

BTW the mods that everyone has presented here look really awesome. Takes a lot of guts to take a soldering iron to a $$$ card. Hats off to everyone.

Thanks for posting your pics guys and I asked Morlak to post his pic of the ViperJohn modded card ... regardless if the person modded it himself or not doesn't matter to me .... I do think you all did excellent jobs on your cards and each reflex your ingenuity, skill. I'm only after a collection to share with everyone ...... my last card went out to ViperJohn and I too like his work .... wait until you see his new ViperFang WB and WB/TEC versions .... anyways everyone is welcome to post their pics, all I ask is you just post your pics and be proud ... :D .... hey Sik ... can you slide me a sticker Bro :cool:

Hi !

First post here ! :rockout:

**sorry my poor english...**

I got a Sapphire X800GTO² and I plan to vmod my card. It will be aircooled with an ATI Silencer 5 Rev.2. What mod do I need to perform ? Do I need the 4 vmod (IGPU, VGPU, VDD, VDDQ) ?

Thanks !

ok I vmodded my card

what voltage are safe on air ? (VGPU, VDD & VDDQ)
I was thinking VGPU @ 1.5v, VDD @ 2.3-2.4, VDDQ ?

Can't wait to receive better cooling to push my card :rockout:

It seems that the GTO2s have really nice cores! Maybe i try to get one and sell my X850XT. :D

What Vgpu for the 620MHz? I need 1,58V for that, surely stable for hours of gaming. ;)

Hi,

First, sorry for my poor english,

I'm new here and this Forum is really interessting.
As I'm also overclocking, I thought I could ask some questions about your expierences.

Well, I've a X800XT PE and already done a Voltmod@1.68Volt. Now the stable speed is 630Mhz.
Mem speed is 610Mhz (also voltmod @2,12V
But if the card is under load like in games or benchmarks the Voltage goes down to 1,58Volt.
Is this normal??More important; can I avoid this behavior of the card.
I've to say everything is cooled very well (GPU temp@load max. 40°C)

By the way. Does anyone know where exately are the Voltage-changer (oh I don't think that the name it called; hope
you will know what I mean, Sorry!) I think I've found them already but only to be sure.

How high you getting your card? Is 630 already the end?

Thanks everyone!!

Welcome Nightmare ... the vdroop is normal, I have a X800XTPE as well at 1.70v and the voltage will droop .05v - .08v as well, with 645/630 max stable speeds ... check out the card here (http://forums.techpowerup.com/showthread.php?t=3864) ... post some pics :rockout:

The vcore regulator is going into active current limiting mode and that is normal behavior for an x800 AGP card. If the regulator is running in spec, which yours is, the loaded Vcore will clamp at around 1.580 even though you are increasing the unloaded Vcore. There are mods to correct it but they are well beyond the skill and tools most user have.

With the correct mods you can also get the Vcore to boost when the card loads up instead of droop.

"This article is based on the previous voltmod article for the Radeon X800 Pro, X800 Pro VIVO, X800XT and X800XT PE AGP line and has been adapted to apply to the Radeon X800 Non-Pro, X800 XL and X850 PCI-Express line using PCB #A474."

This seems to specify PCI-Express for the x850, are the mods the same for an AGP card?

I just thought I better point this out, you havent plugged in two of the power supplies that the motherboard needs. There is a molex to the right of one of the pictures, and a floppy power supply to the left. I also forgot these when I got my ultra-d and so did my mate hwo bought the same board as me :laugh:

Sorry for being a bit of a noob.

But I presume volt modding is used to get higher stable clocks from your GFX cards? Like overclocking a CPU, although that easier to do obviously.

Will it reduce the chance of artifacts aswell?

Is there a program that tell me what voltages my card is currently running at?

If you want your Vmods to be effective you need much better GPU amd memory cooling t go with them.

Finding the max clean OC's on a GRX card is harder and much more time consuming than OC'ing a CPU. The latter is a cake walk in comparison.

First of all, sorry for my poor english, i'm spanish and i can't write english as well as i want.
Let's go:

I'm new here and I want to ask you some questions, i'm going to Vmod my Sapphire X850XT and i need to know if your article can be used with my card too, and what speeds could i get if i mod it.
Now i have the card with stock cooler (waiting my WC kit) and i have it flashed to PE, and it goes well, but i need more and more!!! What speeds could i get aprox without vmod? When i pass from 570 on core speed, with 590 on mems, my system hangs up, is it normal?

Help me plz!!! Thx guys!

The stock cooler is used to hide few things... ;)
With the special mods the card can run 3DMark05 at 750MHz (gpu) and 675MHz (memory) with tight latencies. Thats just aircooling...

Actually it isn´t :)
The power regulation of the card has completely been changed.
The card doesn´t any longer draw power from the motherboard, all power is supplied by the PCI-E power connector.

Also the gpu overvoltage protection (OVP) has been properly disabled, core transform voltages are fully adjustable, there is only a minor fluctuation in VGPU and VDDR voltages, etc...

Basically the trick is to enhance the cooling of power regulation cirquits and add few components to right places ;)

These mods gained over 100MHz for the gpu and 40MHz for the memory.

Very nice Stilt .. slick place for the VRs right in a perfect spot ... where the heat sinks come from you used ?

[infrared]

What are the components you put the sinks on? I've been looking with curiosity at them on my card. Mosfets or something?

I'm conisidering volt modding my card soon, but first i need to find a decent cooler for it. I'm gonna do a simple pencil mod first though, so i can see if it's really worth putting a VR mod in place. Oh, and whats the best way of getting the graphite off if i get too much on the resistors?

Great work everyone in here!

The heatsinks are the same that DFI uses in their NF4 Lanparty boards as mosfet coolers.
I got mine from the local electronic shop. They appear to be identical to the ones that DFI uses.

The big heatsinks are for the power choke coils.
After the mods I measured 115c degree surface temperature with my Fluke IR thermometer, during 3DMark05 run. If I would have disabled the card capability to idle, they would probably have melted off without the heatsinks.

With the heatsinks and 40mm Sunon Maglev fan flowing on them, the coils stay at 50c (max) under the load. Thats a bit less than stock card with default cooling.

[infrared]

oh cool, not bad :)

how did you stick them on? Double-sided tape or thermal grease + a small dab of superglue in the corners?

I used Artic Silver thermal adhesive.
I haven´t used that old TIM + superglue trick since... err.. for a long time ;)
Thermal adhesive allows the heatsink to get a better contact unlike when using superglue and TIM.
Syanoacrylate isn´t that good heatconductor :)

Never use a Silver or metal bearing thermal adhesive or compound on memory chips. They are capacitive (not conductive) and if any squeeze out gets under a chip you can end up in the land of hurt real fast. Use only AS Alumina Thermal Epoxy or Alumina/Ceramique compounds.

Viper:

I don´t use any heatsinks on the memory chips.
I know that even Arctic Silver claims that their "Silver" series products aren´t conductive, they actually are (a bit). These products can instantly kill the card if the stuff makes it way to those bga solderballs or legs of ic.

I only have heatsinks on the choke coils and gpu power cirquit components.
I also use a slice of tape to protect the legs of IC from getting shorted by the glue.
When the glue has settled, I can rip the tape off.

Thanks for the warning thou :toast:

I only have heatsinks on the choke coils and gpu power cirquit components.
I also use a slice of tape to protect the legs of IC from getting shorted by the glue.
When the glue has settled, I can rip the tape off.

Thanks for the warning thou :toast:

Oh they are ever so slightly conductor but at the voltages we are talking about it is on the order of harmless stray leakage currents. They are capacitive though are that is what will screw the memory and cause the display to go corrupt if any get under the chips. The compounds are no problem as an Acetone spray cleaning will get wash the stuff out. If it is hardened epoxy you are hosed and are now the proud owner of an expensive paper weight.

A lot of prople over look those PS series inductors and they are usually the hottest running parts on the cards lol. While heatsinking the inductor itself doesn't do anything for it, it does keep a lot of the heat they produce from conducting through the PCB glass and heating everything else around them...like the closest memory chips.

Just finished the mods of GTO² T.S.A Edition (prototype).
This card is supposed to be used by customers, so I made the mods little different this time.
I didn´t use a resistor for GPU mods, but I used VIDs instead. The voltage can be adjusted via jumpers so the customers do not necessarily need a multimeter. They just have to install the jumpers correctly and they will know exactly how much voltage is fed to gpu. The gpu voltage can be adjusted between 0.00V - 2.00V, but the warranty is voided if 1.65V exceeded ;)

Since VDD & VDDQ voltage cannot be changed by VIDs I used variable resistors with safety features. The voltage can be adjusted up to 2.35V. There is another variable resistor added in cirquit (one for VDD & VDDQ) to make sure that the resistance doesn´t drop below certain point (that corresponds 2.35V).

I used some Microcool and Coolermaster heatsink for the power regulation components.
As usual, I attached them with Arctic Silver Adhesive.

For the gpu I added custom made 600g pure copper heatsink.
It can keep the gpu temperature under 50c in full load and 700MHz clocks.

I had to run some 3DMark05 with the last version of the "prototype" card.
The card is pretty much an average overclocker, but it is still doing pretty nice with quite weak fan. I selected 1.60V for the gpu, and 2.2V for the memory (VDD & VDDQ).
The memory will be doing much higher, once I install the heatsinks.

Sapphire X800GTO² T.S.A Edition: GPU 705MHz (1.60V), Memory 651MHz (2.2V).
Intel Pentium 4 670: 4505MHz (18x250) 1.38V
Asus P5WD2 Premium
Corsair 5400UL 1GB Kit: 375MHz 3-2-2-4-2 / 2.2V

Luck... Remember, Stilt goes through litterally hundreds of cards looking for those 'gems,' which he then refines even further by volt-modding and putting some kick-ass cooling on it!

Basically, if you only pick up one card to buy, it could be a good one or a bad one, some cards barely overclock at all, and some will get up to some awsome clocks. Some handle the voltage well, where as some others (of the same batch) might not.

Just like ViperJohn said, the resistor is not needed.
Just replace the excisting one with a small bridge or 0ohm resistor.
You can also use some conductive paint to short the resistor if you don´t want
to unsolder it.

[funkflix]

Ok, thx both, thought i must bring down the resitance ro 20k?! :)

Is there a another way to get over ~1.8V? ;)

[fire113]

hi guys

...just messured vdd and vddq :) both 2.10~2.11 V semms that I only have to do the Vgpu mod :)

Without any mod or biosflashing I can run 575/616 with ATItool but it tells me R430.It is a R480!!! I have seen it. I´ll do the Vmod next day´s.

cu fire113.

[ViperJohn]

Not needed?

I've never run the Vcore than high as it is typically well over the wall for 90% of the cores made even on phase change. A couple of my customers have run X850's at 1.850 loaded Vcore without issues though.

On R420 cards dynamic current limiting by ever widening the unloaded to loaded Vcore droop will keep the loaded Vcore under 1.60 anyway if the FAN5240 is operating within spec unless DCL is modded. That has nothing at all to do with the Igpu shutdown timer setpoint mod.

I'm on a maze4 acetal, and my temps on my gto2 @ 550/615 are 28c idle 32c load. I have a lot of headroom cuz of my nice temps. I want to get more of an OC on both core and mem.

I don't think u are from germany, or? So it will not help u to tell u the shops i bought the parts. ;)

The blues are two, just glued together and all VRs fixed with glue on the PCB.

[g0dM@n]

Thx for the prompt response. I will just try radioshack or something in the US I guess.

So you hotglued the VRs down? Also, none of you recommend the iGPU from what I see. I guess I'll just do the VDD, VDDQ (no clue what this really does anyways), and VGPU. I'm looking for 650/650 as my goal.

[funkflix]

So you hotglued the VRs down?

Yes, but no hotglue, it is with "superglue". ;)

U do not need the Igpu, if u not want to give more then 1,8V to the GPU. Do the Vgpu and Vdd + Vddq and u should reach 650MHz for the GPU, but not sure for the RAM, bcs. a lot of times, u get no gain from voltmodding it.

@ViperJohn

U can tell me the reading points for Vdd and Vddq on the card i modded? It is a different layout. I messured on the first resistor and got about 2,049V, but don't know if it is Vdd or Vddq. :)

Asus X850XT PE AGP
Used 2x20K 25 turn pots.
Used bridges (dont realy know what they are called) from my old IC7G (may it rest in peace, awesome card) for the VGPU VID adjustment.
Revoltec copper BGA coolers. (Realy bad quality sinks, but I took of the thermal tape and lapped them flat. Then glued them with Arctic Silver Addessive).
OCZ ramsinks (high quality sinks that are smaller then the revoltec counterpart. Used them under the waterblock tubing)
Made a block that fits between the GPU and Waterblock from a old Danger Den coldplate.(Had to, could not seat the waterblock. It touched the ramsinks)

So far I have only tweaked the VGPU, VDDQ and VDD pots at 20k.

3DMarkXX scores are low because of bad motheroard thats holding me back.(dont clock, cant run tight timings, basicaly sucks. =o( )

Had 7330 points in 3DMark05 with ic7G at fsb 275 MHz and graphx at 610/630 core/mem.

I dont agree. If Vmodding dont help. Then you probably work on the wrong V-line. Adjusting the right voltage always gives you some performance gain. Have you tried the VDDQ? That might be holding you back.

Adjusted my VDD and VDDQ to 2.2V. Now highest stable clocks are core 670, mem 666. Scary the number of the beast..... :twitch:

-> I might try putting some VR's on it<- ...jau thats the way I did it and I think it is THE BEST WAY to do any Vmod.
My GPU and Ram was watercooled! and I went up to ~1,68 V on GPU an on Vdd+Vddq ??? I think it was ~2,11 V but not really sure (toooooo loooong ago) maybe U should start with LOWER VOLTAGES to be on the "save side"

Why is it so ?...or do I have to do the VID Vmod ? works this VID-Vmod better then the Vmod with VR ?
Still have a X800Xl bios on it will the ramclock gain by changing to X850XT PE Bios???

With default ramclock´s I can go up to 697 on GPU :toast:

I think you need the VDD and VDDQ mods to run your mem higher. Testet my gpu with 1.65 V, managed to push it to 681 MHz error free. At VGPU 1.6V VDD 2.2V VDDQ 2.2V, I´m maxed out at 670 MHz gpu 670 Mhz mem. :toast:

As you can see from the pics, i made a nifty measuring point on each of the vmods by hot gluing a piece of soldier to the top of each resistor. This makes measureing the voltage easy!

The left resistor is for the vgpu as you can probably see, unfortunatly the mod isn't effective, and only increases temperatures, so that one's just sat their giving me the option to toast the card if i decide i want a new one! :D

The two on the right are vdd and vddq mods, i love those! Originally i had a max of 555mhz on the mem, now with 2.4v vdd and 2.05v vddq i can achive 610mhz :)

I'd like to thank urlyin for posting the vmods, very useful! Thanks ;)

[Urlyin]

Thanks for the pics Infrared ... nicely done and the measure points look good :toast: .... so you can increase vcore and voltage goes up but your clocks do not?

[infrared]

Nope :( I went all the way to 1.7v and still no stable increase in speed. Strange :ohwell:

Soldiering to those contact points was the most challenging soldiering i've ever done tho! :laugh: I sliped and connected all the nearby components together!! Took me ages to get the soldier off :D

The increase in speed on the memory definatly helped a lot though!

The X850XT PE seem to be to good for the old intel platform, S478. Installed some new Twinmos SP PC3500 with Hynix D43 chips on it. Run the computer with fsb 260 and slow latencys. Without changing any clocks on the graphx-card my 3DMark05 score jumped from 6800 to 7528 points. X850 still at gpu 660 and mem 660. With my old bh-5 I couldnt run higher than 210 with tight latencys on my ASUS mobo.

Please tell me what is the max temperature to your GPU and GPU ambient and memory!!

I can only tell you what the GPU and Ambient temperatures are because there isn't a temperature sensor in the memory chips.

Clock frequency Core: 555 / Memory: 1180
Stock voltages:
- VGPU: 1.41V
- VDD: 2.01V
- VDDQ: 2.08V

Temps GPU idle: 28ºC
Temps GPU stress: 37~40ºC
Temps Ambient idle: 27ºC
Temps Ambient stress: 35~37ºC


Clock frequency Core: 645 / Memory: 1224
The voltages that I used are:
- VGPU: 1.65V
- VDD: 2.18V
- VDDQ: 2.24V

Temps GPU idle: 30ºC
Temps GPU stress: 47~50ºC
Temps Ambient idle: 30ºC
Temps Ambient stress: 43~49ºC

Please note that the area around the Choke Coils (The area where the ambient temperature sensor is settled) is actively cooled by an 80mm. fan.
If I disable that fan, the Ambient temperature will rise to 60ºC+ !!!

and also why do it on a crappy ati card that is outdated and showing age compared to todays cards

[tazz0r]

I got a Foxconn X800XT flashed to XTPE

Stock:
vgpu: 1.42v @ 575
vdd: 2.01v @ 560
vddq: 2.01v

Mod:
vgpu: 1.54v @ 654
vdd: 2.45v @ 618
vddq: 2.25v

All pencil mods. I didnt brave the wiremods because im a wussy :rockout:

the card has got an AC on it atm, but just got a new watercooling kit, mainly for my CPU with an added 320w peltier for the sub zero temps, may do same with vgpu and add some more volts to it, see what I get.

with the AC the card peeks at about 60° when its cleaned out properly with an airline, but does get dusty.

Stock 3dm05 is around 5800-6000

with the mods and overclocks, card at 654/618, 7767 on 3dmark05.

Also need to update my sig. as i've got my opty higher too.

Also sorry for no post pics i'll get them asap just not got any batteries in cam :D

cheers

how do you guys learn how to do all this stuff

how do you guys learn how to do all this stuff


On forums like this, and from what other people have researched about things. Such as someone has found out which resistors on the X800 control the different coltages that flow through core and mem etc, then people have expanded on that and more and more people pass info on. For all different cards, cpus, and other computer hardware.

Its an endless circle :)

like the cpu and system memory, generally, if you add more voltage(and more cooling), you get to overclock further

why on "crappy" cards, well, so we can spend half the price for a card that, when modded, outperforms the better cards, sm3.0 be damned :P

Hi i'm looking into doing VGPU, VDD and VDDQ mods. I have Asus X850XT which is at 545/555. I'd like to find max for this card but have couple of questions. I have some spare sinks and want to now where to put them. There are no visible RAM chips so perhaps they can go on some of the other chips that are visible. Please explain exactly where they would be most useful - I have 8 sinks so please say all possible places they can go.

I measured VGPU, it's 1.42 stock. Think VDDQ is 2.08 and couldn't find VDD read point. The cooling on this card is an all encompassing thing, similar to this..

http://rgpsales.com/images/AS10RX850XT-H.jpg.

It keeps idle temps at about 36'c for 545/555. Anyhow, i'd like to know what you think max VGPU, VDD and VDDQ is safe for my card. Once I know what to aim for i'm gong to do the pencil mods and maybe VID mod. :twitch:

[Urlyin]

RAA ... read this article here (http://www.techpowerup.com/articles/overclocking/voltmods/112)

[RAA]

Yea I read it but thought maybe cause of this cooling I can run higher volts. It's nice heatsink on RAM and powerful fan. The way the whole cooling unit is screwed onto board means that other side where RAM chips are, are covered and compressed by the metal. So the chips get passive from heatsink and active cause fan is right next to it. I could maybe put some sinks on the other side where metal strip is..

For rest of copper sinks i'll use them on the chips pointed out in that guide but also is there any where else on the board that they would be useful.

From that thread i'll go for 1.45v VGPU, VDD has active and passive cooling so 2.45v ought to be ok? And VDDQ 2.16v - 2.18v .. see how I go with that.

Btw what's an acceptable idle and load temp?

If you're doing 2.45v, you should make sure you have air going to all chips...

As for voltmodding your GPU, you can go quite higher if you were to keep temps low. Have you thought about buying a better cooler? You may get your hands on a VF700CU for <$20 used. Those are awesome coolers for x800/850s.

Acceptable idle temp, or better yet ideal would be 30-45C. I would be comfortable with load temps up to 65C personally, but some people prefer lower.

I can tell you that even 80C is not unsafe, but definitely don't want to be loading that high for long periods of time. Most are satisfied in keeping the card [on air] under 60C. It's tough to keep it much cooler than 60C if you're aircooling on a voltmod. I had my card on watercooling with a maze4 and barely broke 40C.

[RAA]

Thnx.:)

Well I must test idle cause I have profiler that sets clocks way lower and fan lower too. I must test highest OC with 100% fans for real idle!

When you say air on chip, do you mean RAM chips or the three chips pointed out in the mods? The RAM chips are covered by a metal strip which forms part of the clamping mechanism for the cooling unit. This strip acts like a heat distribution I guess..

[EDIT] Course 2.45 you mean RAM chips, well I can't remove clamping mechanism without it falling off. So unless I get another cooling unit my current one will have to do. It has very nice big heatsink on other side, but to be on safe side I will go for 2.30v .. howz that sound? Maybe 2.4v if I stick sinks on everything and two case fans mounted on card..

In the guide it says 1.45v to 1.5v is ok. Currently i'm at 1.42v/1.43 so not much head room. I will be doing pencil mod except using new method of using nail polish and nail thinner with 2B pencil graphite powder. See here :rockout: http://www.ocforums.com/showpost.php?p=4436705&postcount=141 The ratios can be changed to give different levels of resistance, I got to loose a mere 15 Ohm for VGPU so going to require lower graphite ratio. This method is perfect for these mods.

Well, heres a pic of my temp setup. i havnt tested it out yet other than reading voltage. im not sure if i did something wrong or if im just being scared to turn the VR too much. I can only seem to get it to 1.45 and 1.46 no higher no lower. i turned it a good 6 turns both ways. i used a 15 turn 10k VR.

let me know what you guys think. thanks

Tony did you measure the resistence on the VR, before you soldered it up using a multimeter?

[Tonyklem]

yes, i adjusted it to 10k before i soldered it on. oh just to make sure. The 3rd leg of the VR wasnt changing when i turned the pot, so i assume i dont need that one, correct?

The problem is :

When tested with atitool cube it "blacks out" (like a tv set switched off) after a while at 459MHz core
where if not modded atitool cube would stall

x800XL's core respond very poorly to volt modding most of the time. There are occasional exceptions but they are very rare. You also have to start with a card that has an aux power connector or you will go absolutely no where fast.

The real problem was the process used to FAB the core. In order to keep costs lower ATI did not use a lowK process on the x800XL dies in FAB. The result of that is the cores have very high internal leakage currents to begin with. While increasing the Vcore does increase the OC potential of the core it also increases those leakage currents about 4 times faster than OC potential does and you end up getting very little OC increase from running higher Vcores. You also hit the Vcore wall where no amount of increased Vcore results in tangible OC increase very early.

On very high end air (about 46C loaded after modding and OC increases) with a lot more cooling ability than an Arctic Silencer has the average OC increase from higher Vcore was only about 15-18Mhz. Once in a while you would get a card that gave more but many gave even less.

[Urlyin]

I wasn't aware of the core FAB issues... but VJ makes a point in regards to the aux power...
also don't rely totally on ATITool, test the oc with some graphic intense games as well ...

Actually I should clarify a bit. Only the R430 cores were fabbed using a process that was not lowK. You have to check which core your card actually has as many x800XL's that were sold were actually rebagded x800Pro cards (PCB and all!) with R420 cores and they love Vcore!!! There were many build games played with the XL PCIe cards.

My card is similar with PowerColor X800XL (mine is Daytona)
but I have Samsung 519 K4J55323QF-GC16
which means 1.6 ns memory instead of 2.0ns for PowerColor

Article http://www.digit-life.com/articles2/video/r430-2.html
"What we see is the same R430, which was for some reason called X800 PRO from the very beginning, though its a sterling 16-pipe chip. Probably the company wanted to confuse users again (even before the final decision on X800 XL, X800 titles) and called such cards X800 PRO (to have them confused with the 12-pipe AGP counterpart)."

I do have an external power connector

Reference X800XL looks like this (without external power connector )

http://img160.imageshack.us/img160/2361/referencex800xlscanfront6lb.jpg

I have R430 (as you know it "has" 0.11 microns instead of R420 which "has" 0.13)

R420 looks like this :

I understand the issue with current leakage, that explains why the power regulator
ncp 5424 enters in current limitation.

I want however to resolve I gpu for ncp 5424 so to obtain the most of my card.

Please if you could "study" ncp5424 and tell me how to avoid current limitation ( I gpu )

Why R420 works at 85 C loaded

Hey,

The voltmods i've done are nothing special, identicle to the ones i did on my x800xl a while back, so i'll leave out the boring details on those.

With the R480 core running at 1.55v+, 630mhz+, there was a lot of current going through the vregs and powerchoke coils, so i managed to get my hands on an old NB cooler off a friend, cut that up, and epoxied them on... Then grabbled a 40mm fan and made some plastic air ducts to help improve the airflow through the sinks. It would probably be ok just to leave the fan off, but it still get's quite hot without the fan.

http://img.techpowerup.org/060526/Thumb7.jpg (http://img.techpowerup.org/060526/7.jpg)

If you look closely at the backplate screws on the silencer, you will see i've made some new plastic spacers. When i replaced the thermal pads on the back with Arctic ceramique, the screws wouldn't go down the posts far enough, plus the plastic spacers let me tighten the cooler more, compressing the thermal pads on the front memory.

Anyway... voltages:

GPU:
1.4v = 580mhz (stock volts)
1.48v = 610mhz
1.52v = 625mhz
1.55v = 645mhz

VDD/VDDQ
Stock = 630mhz
2.38/2.36 = 660mhz
2.45/2.43 = 675mhz (80mm fan blowing over backplate)

Managed 7640 in 3dmark05. Hopefully i can boost that score a bit with some half decent memroy.

EDIT:

My baby just managed 7748 in 3dmark05 with:

Hi, I have a couple questions concerning this mod. I am only intrested in doing the gpu volt mod. I want to try and see if it worth the effort. I have an x850 pro bios modded to an x850 xt pe. it runs 520/600 stock right now on aftermarket air cooling. I'm not looking for the insane clock speeds most of you are getting, but at least a 550 on the core. Can I just do the vpu mod for the core, and not do the memory mods if i just want to slightly increase the clock speed of the core?

Thanks, and im sorry if some of that didnt make sense, im a noob

[infrared]

Yeah, it's perfectly ok to only do the vgpu mod, but unless your cooler is up to it, don't exceed 1.5v, and try to keep the temps below 70c. You should get to 550mhz without problems.

As you can see from the pics, i made a nifty measuring point on each of the vmods by hot gluing a piece of soldier to the top of each resistor. This makes measureing the voltage easy!

The left resistor is for the vgpu as you can probably see, unfortunatly the mod isn't effective, and only increases temperatures, so that one's just sat their giving me the option to toast the card if i decide i want a new one! :D

The two on the right are vdd and vddq mods, i love those! Originally i had a max of 555mhz on the mem, now with 2.4v vdd and 2.05v vddq i can achive 610mhz :)

I'd like to thank urlyin for posting the vmods, very useful! Thanks ;)

You can always send him an email.

To be honest, at the prices the x800/850 cards are now, it's almost worth it to try the mods yourself... the cards cost only $100 ish now. :)

You can easily hit 8,000 in 3dmark05... I hit 7,800 without voltmods with a 3ghz dual-core AMD. You maybe even hit 9,000 if you go nuts with volts...

Im using an AGP system, no can do.

well here in the states, it was selling for like $120, and ppl sell em used for like $100... which is what i've posted mine for elsewhere.

i think ebay sells em cheap too.

X800XT AIW with zalman heatsink, and an air deflector made from the bottom of a plastic food container. It has an opening at the bottom for the zalman fan, and is held against the heatsink by four zip-ties. The purpose is the direct the airflow upward, as the exhaust is at the top of the case.

hi all
can someone explain me how to do the vid mode?
the pencil mod not working for my gigabyte x800xl
i want to give to the card 1.5V
can i do it with pencil too?
THX!

hi all!

I have Club3D x800rx(gt) 256MB/256bit PCIe r480(hardlocked:mad: )
'want to do vgpu mod, but i have to be sure 100% that it is like this: http://ceemic.pri.ee/hardware/x800gt4mod.jpg <-- am i right?:rolleyes:
R1597 is in "the right" place:D
and also vgpu measure point?

that is correct ...

[ceemic]

...but today one Estonian guy told, that the measure point is on C60:confused:
...and he used 22k wr in vgpu mod..22k ise safer to use?
def vgpu is ~1,4V; what would be the V range with 10k vr and with 20k vr???

[Urlyin]

Yes .. c60 is the correct measure point for the vcore .. here (http://www.techpowerup.com/articles/overclocking/voltmods/112).. have you read through this article?

[ceemic]

tnx, now I have;)
but what do you think: i want to do ONLY vgpu mod because i have killed 2 cards by vmem mod:mad:
should i do igpu mod also? what is the highest voltage allowed by opc or is that randomly different whit different cards?

:toast:

the igpu is not needed.. forget about it.. take your time and do a good job on the gpu

Oh they are ever so slightly conductor but at the voltages we are talking about it is on the order of harmless stray leakage currents. They are capacitive though are that is what will screw the memory and cause the display to go corrupt if any get under the chips. The compounds are no problem as an Acetone spray cleaning will get wash the stuff out. If it is hardened epoxy you are hosed and are now the proud owner of an expensive paper weight.

A lot of prople over look those PS series inductors and they are usually the hottest running parts on the cards lol. While heatsinking the inductor itself doesn't do anything for it, it does keep a lot of the heat they produce from conducting through the PCB glass and heating everything else around them...like the closest memory chips.

I know this is really late, but I was just reading along, and I have found something that will dissolve AS alumina epoxy, without harming the card. CRC brand Brakleen, which is a non-chlorinated brake parts cleaner, will liquify both AS and Alumina Epoxies. Found it out while trying to clean some off a heatsink I'd put a shim on. The shim came off. And yes, the epoxy had been mixed right. Sorry for the quick hyjack.

Interesting...I have used that very product for cleaning many things, many times and have never seen it dissolve hardened epoxies. It originanlly contained Perclorethylene (Dry cleaning Solvent) before it went non-chlorinated a few years back. Not sure what it is in the cans now.

I never use epoxies anymore so it is kinda a moot point these days I guess.

I'm still using them just for the purpose of extra cooling. I know thermal tape is easier to work with, but how well does it actually conduct? I've never seen it outperform a thermal epoxy, so I'll stick with what I know. In fact, I just put some larger heatsinks on my card's ram with some alumina, and dissolved 4 month old arctic silver epoxy with some brakleen. It doesn't dissolve the really thick stuff, if too much was applied, but the thin layer it takes care of with a little rubbing. So far I've not seen it damage any electronic component, either, so I feel it's as safe as pure rubbing or denatured alcohol.

Rubbing (Isopropyl) alky shouldn't be used for anything but a disinfectant. It contains water and it a poor cleaner. Denatured is okay but Lacquer Thinner is the best.

Thermal tape, commonly know as Frag tape, is absolute thermal crap. Very high end self adhesive thermal interface material (SA-TIM), when installed properly, can achieve thermal interfaces that perform with 1-2C of properly applied thermal epoxy. The problem with them is they cost a freaken fortune and you can't get them at the retail level in small quantities. The heatsink base flatness requirements and cleaning/install procedures are very strict and must be followed to the letter too. The bond strenght can be high enough to rip memory chips right off the card if mishandled or if you rush the heatsink uninstall in any way.

I haven't heard of the other tapes before. As for ripping pieces off a circuit board, yeah, been there. I killed an old motherboard because the epoxy broke one of the power mosfets. Turned out to be a discontinued item, and I couldn't find anything similar enough for very cheap. I've had a few mishaps with any heatsink bonding material. Lacquer thinner for cleaning? I prefer the smell of brakleen to that stuff, not to mention it tends to leave a bit of an oily residue behind. Besides, aren't some PCB's coated with lacquer?

It wasn't Lacquer Thinner if it left a residue. LQ contained on oil just like Acetone and dries clean. Actually LQ contains some acetone but it's not nearly as dangerous to the lungs as pure Acetone if you should inhale any fumes.

Lacquer hasn't been used on PCB's for many, many years due to air quality regulations. Rarely are consumer level PCB's coated with anything. I have seen one that was in years. It adds production cost needlessly to something with a relatively short lifespan due to rapid (<4-5 years) upgrade cycles. Commercial/Industrial PCB's, when seal coated, use conformal coat (getting rarer) or epoxy these days but it make repair a bitch on PCB's that can have very long service lives in the field. It is often a rough service environment option.

I might be thinking of paint thinner instead, unless that is the same. Stuff stinks, and if it burns, it smells like kerosene.

Yep Paint Thinner for thinning oil based paint. It is not the same LT at all.

Awesome, maybe I'll try using some. At the very least it'll be less volatile, and hopefully less noxious smelling than the brakleen. I'll check and see if it'll dissolve the epoxy, too. Normally, I wouldn't think anything would, aside from intense heat. Oh, and while you've been responding, do you know where I could find the info on modding my blue AGP x800GTO? My board looks different than the blue one in the tutorial, and nothing like the reb PCB, either. Neither of those boards have the rialto bridge (mine does). I'd first like to check my gpu voltage, and I know my vdd and vddq are both .09 volts low (1.99), although that doesn't change under load or when idle. If you have any pictures, tutorials, I'd much appreciate it.

Hello,
I'm kinda of new to these forums and i am not sure if its the right one but anyway, i have a sapphire x800gto not gto2 and i would like to volt mod it. It's already changed to 16 pipes and also overclocked a bit From stock 400/495 i went up to 550/570 but in the atitool test for artifacts after 1 min or so i am getting a lot of them. If i leave it like that there is no problem in games at all. I know it's the memory causing it because if i lower it to 500 no artifacts in atitool. So a bit of a volt mod would be nice, more volts higher clocks, but i need some instruction on where to sold and what resistance etc. Type of card: SAPPHIRE X800GTO AGP, 256/256, R480, memory samsung 2.0 ns. I have included some photo of the card as well, any questions - just ask. Any help will be apreciated. (srry poor english) thanks

What cooling are you currently using on the card? If you plan to voltmod it, i would definatly recommend putting a decent cooler on it first, otherwise the card will overheat with the extra voltage, and actually clock lower.

Here's the article for the mods anyway :)

[Ciprianni]

thanks for the answer... but my card looks different then the one in the article. i have a zalman cooler and some heatsinks on the memory. i have included a pic :)

[infrared]

Hmm, looks more like the x850Pro PCB.
