memory timing bios mod?

[Solaris17]

modify the timings of the ram in the bios of the card.

[Scrizz]

all the love going round and none for me? :( :cry:
:laugh:

[Solaris17]

whatya need scrizz?

[Skitzo]

Did some benching, this is what I ended up with:

E6750 @ 3.44 Ghz
9600Gt 828/1067/2070 ... idle 44C full load 64C (so far)
12122 3dmarks

getting better...:rockout:

air cooling...but it's in the basement.

[Solaris17]

w0ot!!! its great stuff isnt it? the card is actually pretty powerfull considering other highend cards.

[Skitzo]

I just looked at wolf's clocks again...wow! I had a feeling that the alpha dog would oc a little past the other gt's. Woohoo:roll: :toast:

[Skitzo]

yes yes yes ... I'm impressed. :)

[Skitzo]

I think I could push it a little more seeing as I was testing and benching with dual monitors except for the last bench.:)

[Skitzo]

Hey Wolf, Your 8800 better pick up the pace, a volt mod (is there one?) could see my 9600 closing the gap even more. :pimp:

[Solaris17]

pssst "8500/8600/GT/GTS mod guide" ;)

[Skitzo]

got it...:)

[Solaris17]

take a look at this pic, are these burns from my oc or manufacturing?:confused:




edit: I see a scratch and burnt component aswell: see zoom pic

i dont think those are burn marks but instead i think it was a spill....your supposed to put down this resin stuff b4 you solder a resistor the the board and then you clean it up..it simply looks like the machine squirted out to much and it just dried to the pcb

[Skitzo]

Good to know, gotta decide what to do with it.:)

[wolf]

for some reason my 8800Gt wont boot in any system with the quad core overclocked, it always makes it screw up and revert to 2.4ghz, thus my 9600GT is currently my fastest card, which is weird cos my 8800GT is 800/2000/1900 and with the quad at 3.6 should be looking at near 15k 3dmakrs. any ideas on why a mobo oc is sensitive to a gfx card sol?

PCI-E freq? try clearing the cmos and then putting the card in and trying agian..also check you power cables make sure your putting them in the same order and not mixing them up the 8800 requires mroe power so you may be getting the low voltage blackout.

[Scrizz]

yeah I'd say check the pcie freq, it can cause the system to not boot.
make sure it's not set on auto

[wolf]

its just so weird cos if the mobo is at stock settings (2.4ghz) then its all fine, its only after i start to overclock that it reboots at post.

[Solaris17]

voltage instability? hmmyou have all that intel speed step eist stuff off right?

[wolf]

absolutly, its a very confusing conundrum, i really wanna bench that vmodded 8800GT with the quad running so fast!

[wolf]

modify the timings of the ram in the bios of the card.

assuming that our cards share the same vmem, what timings should i use, im aiming for 2200mhz effective.

[Scrizz]

Hey Wolf, you could send the 8800gt to me for further testing ;)
:laugh: :D :rolleyes:

[wolf]

depends what your sending me as a swap :D

[Skitzo]

I'll send you my 8600GT with a V2 ... but wait, it's cool cause it's got tattoos. No volt mod yet but I thought about it lots so that should be worth something... ;) And don't forget, she's famous ... she's got pics on the internet. oh yeah it runs at 770/905...should do well with a v-mod. :)

Try making sure that the PCI-E freq is set to 100. Make sure that all voltages and freq are set by you and not on auto. With the OC cpu, your board might be clocking up something that the card can't handle and thats why PCI-E freq seems like the most likely cause.

You could try base clocks and try OC the cpu slowly and see at which point the card stops responding. Write down the clocks to refer to when this happens.

how does two dead X1800XLs sound

how does two dead X1800XLs sound

That sounds like you were drinking and OC too much :roll:

[wolf]

not enough oc vitamins :D

[Dobbie]

Did you get the card working right with the OC?

[Scrizz]

not enough oc vitamins :D

yeah I forgot to take my OC OJ :laugh: :p :rockout:

[wolf]

i would have gotten it working fine, if i hadn't already swapped it for a 9800GTX :D

[Scrizz]

I can't w8 to get my HD4870x2....

[wolf]

why would you buy that? nvidias next gen will probably woop it, not to mention a single gpu solution will always be better than a dual.

[Scrizz]

b/c why would you get a 9800gtx when a g92..... $$$ me want 9600gt?

[wolf]

what?? that didnt make sense

[cdawall]

why would you buy that? nvidias next gen will probably woop it, not to mention a single gpu solution will always be better than a dual.

why woudl a single gpu always be better than dual that doesn't make any sense. did you forget these aren't like the nv dual cards they are actually thought out and well planned not just 2 gpus taped together

[wolf]

why woudl a single gpu always be better than dual that doesn't make any sense. did you forget these aren't like the nv dual cards they are actually thought out and well planned not just 2 gpus taped together

well it must work because their 2 gpu's "taped" together whips ati's 2 that are "well planned" lol.

and what i mean about the single gpu remark is that a better gpu will always work better than 2 worse ones. obviously per say 2x8800GT will outperform one.

for example ill compare 2x8600GT with one 9600GT. one 8600GT is exactly half of the 9600GT, with 8 ROPS, 32 shaders, and a 128 bit bus, but when in SLi they wont perform as well as one 9600GT (assuming clocks are the same). therefore the single card is better than 2.

and here in aus the 3870 can be had at ~200$ whereas the X2 is ~600$, not to mention an X2 does not run games twice as fast as a single card. so the single card is waaaaaaay better value for money ($$ for FPS)

what im suggesting is to wait for a single card that is as beefy as 2 are now, for example an nvidia card with 32 ROPS, 256 shaders, and 1024mb of vram over a 512-bit bus, as oppose to a GX2 (just an example)

so far the rumors indicate that the 4xxx series will be up to 50% faster than the 3xxx series. at least the rumors of nvidias new gpu make it seem like a true generational leap, as oppose to the revision war thats been going on, not that it works out bad for us consumers :D

[Dobbie]

i would have gotten it working fine, if i hadn't already swapped it for a 9800GTX :D

:eek: 9800 GTX.............I want one :(

[wolf]

:eek: 9800 GTX.............I want one :(

so cheap, so good, cant argue with over 16k 3dmarks. no game i have tried at 1600x1200 + AA has put it thru its paces yet.

$425 fro the X2 $170 for the single while its not exactly scaled you do get the abilty to run 4 gpus on a dual board which is going to be well past what you can do on 2x 3870s or you could get an X2 and a single and have trifire on the cheap which ALSO BEATS A PAIR.

the comment on nv's card is stupid everyone knows that it beats theX2 and everyone knows a 8800GTS G92 beats the 3870 so why point it out? its still a bad design

2x 8600GTS is not the same as a single 9600GT the are 2 way different cores with different mem buses which a pair of doesn't make it 256bit


however on the wait for the new gpus i do agree with not on the same principles but hey the ideas the same :p

i don't get it man? if everyone knows its better then why is it a bad design? since they cheaped out and slammed 2 together and it STILL beats ATI's heavily R&D'd card, doesn't that make it a BETTER design? it does imo.

[Solaris17]

o cool my bad i hadent noticed take a look at this

8500/8600/GT/GTS Mod guide

[cdawall]

thats pretty much my point.....
but they are way different designs thats like comparing a pair of 6600s to a 7800GT



i don't get it man? if everyone knows its better then why is it a bad design? since they cheaped out and slammed 2 together and it STILL beats ATI's heavily R&D'd card, doesn't that make it a BETTER design? it does imo.

it makes the core a better design not the card G92 beats R670 its as simple as that, but if you look ATi's design can be more easily cooled and is alot easier to mod hence better design IMO. also 6x 3870 beats 4x 8800GTS :p

Sorry Solaris17 I'm the one guilty for starting all the ATI stuff :rolleyes: :D

[Solaris17]

its ok dude :)

[Focus182]

is pushing the fans to 100% safe if u have a low psu or if u dont volt mod it or whatever?

[Solaris17]

yup

[Focus182]

i just uped the fans to 100% and went from 46C to 52C lol .. wonder whats going on there xD

~Focus

[Solaris17]

did you here the fan spool up?

[Focus182]

not realy .. didnt sound any louder

[Solaris17]

hmmm try 98% or something than it may be a buig make sure you set it to 100% in both fan tabs

[pyracy]

Getting ready for the bios tweak, is there anything else I need to know? its an EVGA 8600gts, custom cooling and all, with a case side fan blowing on it, would maybe a custom fan on the top of the card blowing down on it help with temps?

[Solaris17]

well the stock 8600 fan on the evga models suck in sair that pass over the gpu and it blows out tword the back of the case if you have any open air slots in the back of the case it will bleed some heat..any after market cooler would be better but the stock one isnt bad volt modded and with a lapped cooler my idle temps were 43ºC load was round 70ish..so not bad at all. remember with an after market cooler to get ram sinks or your card will burn out but if your strapped for cash or dont feel like doing the work take some 2000 grit sandpaper and lap it works wonders.

[pyracy]

I know i sound like a noob right now, but what is lapping?
NVM, i found it, sounds like a good idea, does it really help that much?

[pyracy]

OK! I got it flashed, now lets see what I can get out of it! Ill post with some temps and such later!

[Solaris17]

k cool and lapping helpos alot i was at 810/1800/2000 and i idled at 43C and loaded at ~64

Thats it I'm pencil modding mine tonight and flasing the Bios! :nutkick:
Thats crazy good!!

[Solaris17]

never had the resistors and corrent turn posts for it....but i was going to hit 1ghz core...i got the card to idle perfectly browsing for hours at 900mhz core...games immedietely artifacted but never crashed ;) if only i didnt blow it up.

[Scrizz]

lol I actually had no artifacts at 900 :p :D

[pyracy]

I hit 743 core,1589 shader, and 1050 memory. Im not idling so great, its at like 48c now....I'm going to try experimenting with some xbox 360 fans left over from another mod project, those suckers push the air! One thing, when I remove my cooler from my evga 8600, will I need thermal tape or will the paste I have do the trick when I replace it? Also, I'm going to go for the pencil mod, I'm getting another identical card just for emergencies lol.

[Solaris17]

paste will do :)

[pyracy]

not sure whats up, I'm benching LOWER now than when I was at stock bios and oc'ed.....I'll post my new and old bios for you to take a look at if you dont mind. new.rom is my bios, and orig is the old one, I added my whole folder that I used for flashing from the cd. I appreciate all your help, without my modding I'd probably be in prison!

Hi,

I was wondering if you could point out what resisters I need to pencil over on my XFX 8600GT XXX. Heres a picture of the back.

This was the best I could get out of my camera, If I need to take a picture of a different location, please tell me. Thanks

[Solaris17]

cameras fine but could you take it out all the way?

[Sureshot2]

Sure, do you need me to remove the waterblock though?

[Solaris17]

no i shouldnt....

[Sureshot2]

Ok, heres the other half of the card, everything should be visible between the two pictures. I'm gonna shut down and pull the card out if this doesn't cover it.

plz stop im blushing :P

[pyracy]

I just took apart my card and replaced my thermal paste, gonna wait untill I have a little more confidence to lapp it, but man, you would have been amazed at the crappy job they did on applying the old stuff! So far, after replacing the paste I've gotten down to 39'C idle, and after a half hour atitool stress test its maxxed at 64', a lot better than before, at my current oc its gotten to 80' max. I'm still not doing as good performance wise though, I think its got something to do with my new bios, but not sure......

Hi. I was just wondering, if I will raise voltage on a new VGA BIOS settings, will I be able to OC my 85GT more? My current mobo doesn't support any options to change any voltages. I managed to push 85GT to these clocks http://www.techpowerup.com/gpuz/gfvzq/ through ATITool (~5h stress), but I think it's possible even more. And what about pencil mods? I really can't get them, sorry. You just pencil the necessary contacts and what's it?
Thanks

Pencil mods just lay down a layer of conductive material that bypass certain resisters. Thus a small volt increase. Check out the layout of your card and see if it matches the layouts from the first page (http://forums.techpowerup.com/showthread.php?t=44216). If not just google the specs on your cards and you'll prob find the places to pencil in.

btw welcome to TPU! :)

have you had a chance to check out my bios and see whats wrong? my performance is lagging a bit and cant figure out why!

Hey Sol, had a go at the vmod. I can hit 875.1912/880 with the pencil mod. Tried the vr mod but it didn't work out. I realized after I took it off what I did wrong. Case ground only works if it's in a case :)
Is there any reason I can't use the fan ground pin on the card?

i dont see why not go for it. i was just throwing up some quick pointers congrats in the vmod excellent work the 8600GT may be out of date and upon its release it was considered "mid end" gaming but imho it is NO babay and holds its own even today...with the proper bios and volt modifications you can make that thing pull some serious tricks out of its hat imo by far the BEST and funnest nvidia card to date to mod.

[Skitzo]

mine will prolly only get used for folding so I'm gonna see what I can get out of it. With the pencil mod I managed ~2300 ppd. Curious if I can hit ~2500 :) stock was ~1400

[Solaris17]

well my philosaphy and if you saw my various 8600GT projects you know what i always did with it PUSHSHSHSHS i didnt have resistors at the time but i had so many plans for my 8600 ill probably buy another some day....i wanted to push that thing past silicon limits i wanted it shaking while it was running. i wanted to sweat and jitter while it was TRYING to complete a 3dmark...im sick like that...but me and electronics have an intresting relationship..i just have to find out "how much?"

[Skitzo]

yeah, it's not working.
I'm sitting here wondering, I don't recall seeing a pic of my card xfx 8600gt xxx with the solder points marked. I picked the chip beside the pencil mod resistor for the vmod. Is that right, or did i vmod my gmem?:)

kkk when ya get a chance ...


sorry about pic quality, best i can do...

[Scrizz]

Excellent choice in cooling there. That Thermalright V2 is great.
My 8600gt never went higher than 53Cat max oc of 930/1966/1000 :D

[Skitzo]

yeah, it cools the core quite well. I'm hitting 53*C @ 875/1912/880 and a Hyper 15mmx80mmx80mm fan. I can't help but think the heat pipes mess with the cooling on two gmem chips; I see that affecting gmem oc. I have to cut up some mosfet heatsinks to hit tight spots, it can't hurt :)

Scrizz, did you do a solder v-mod, if so do you have a pick?

[lycanwrath]

Thanks for the help Solaris :)

Will try these volt mod and post back soon :)

Hi Sol,

Mine is a PNY 8600GT 256mb version and I couldn't find where to pencil mod on the card. The chip layout is different from the ones you have or any other 8600gt on the net. I am a total noob so could you please point out the mod points for me? I'd appreciate your help very much. :respect:

[pyracy]

Just sayin thanks for all the help, I broke down and got a 1 gig 8800gt the other day, but keeping the 8600 for tinkering purposes!

[wolf]

@ pyracy, also a 8600 is great to keep for folding@home, physx or any other CUDA application :D

@ cskpeter and lycanwrath, how far have you over clocked already? most 8600's will clock up to around 750mhz with no vmods, and at that speed or above, you will want to consider better cooling.

my XFX 8600GT's all clock to around 720-750 core and 1750-1850 shaders on stock volts, however the pencil mod did help me head up to 850 mhz :D
also my cards came with pre-installed better cooling, so iw as set on that front.

also if you all havent, try unlinking the shader clocks in rivatuner, my experience shows they clock up very well independantly of the core, they dont add much heat when oc'ed, and they give a nice boost to the score :D

happy overclocking, and i hope Sol can get you all pencil modding soon, just be patient, he is an 8-9 series god around here at TPU, but even gods need time to do their work :)

[lycanwrath]

Hi wolf,

Currently I am at 760\1840\840.
Having tested these speed for a very long time I hav Flashed them into my bios for 3D setting.

Mem Timings are currently at:- trc=33 , trfc = 40 , tras = 24 , trp = 10 , trdcrd = 11, trcdwr = 7 , trrd = 8
I think I can improve on those

I have a Zalman 700cu cooling fan.
I cannot overclock further coz don't hav enuf volts :(, Temps hav never gone past 55 Degees Celcius with my current settings, even after playing the whole day :).

Hpe for god to be back soon ;).

[cskpeter]

Thank you, wolf and I mean it seriously. :)

The default clock was 540/700/1188MHz (GPU/Mem/Shader) and it's now OC'ed to 700/840/1602MHz which is the most attainable setting so far. The card is cooled by zalman vf700 idling @ low 40's and 60's under full-load. So I don't think heat is an issue here. BTW, this is my 3dMark06 score with the current OC at 1280x1024 with all default settings.

3DMark Score: 6354
SM2.0 Score: 2620
HDR/SM3.0 Score: 2380
CPU Score: 2809 with e4300 @ 3.2GHz

I'd love to push my 8600gt further like you or Solaris did. Well maybe not to the extreme but at least some more than now and that's why I asked for help. Thanks to you now I know unlinking the shader might boost the performance. I will definitely try that and report later. Thanks again wolf and I will look forward to hearing from anyone with any comment or tip.

[edit] Gee, I am behind lycanwrath with posting message and his card is slightly better OC'ing than mine. What's up with that? :D Hello, lycanwrath!

[wolf]

awesome, he is the one that helped me get a pencil mod happening on my 8600GT's, which also came with that very same Zalman that you have on yours.

id say you can gun for 850-900mhz once its penciled, and these poor old castrated cards actually do reasonably well when you overclock the nuts off them.

i always wanted to get to 1080mhz core and 2400 shaders for that magic 100% overclock.... however i have other cards now that warrant my time more than that :P

EDIT: good to see your doing well cskpeter, and to all of you 8600GT overclockers, what brand cards do you have?

[Skitzo]

I haven't looked into the solder vmod any further, gotta take some better pics. My 8600 has been folding for ~1 week at 875/1912/800 with the gpu pencil vmod. hasn't gone over 48*C and is pumpin out ~2200 ppd.


edit, i stuck a bunch or ram sinks on the vregs and was surprized to feel how hot they are still getting, something to consider.

[Skitzo]

hey Wolf, your card has the same layout as mine righ? If so would you guess that the chip to do the gpu vr mod to would be the one beside the pencil mod resistor? I gave it a go and i couldn't get it stable @ 800. After disconnecting it I've come to the conclusion that I was either getting a poor ground or that was the gmem vr mod...

edit: I'm gonna vr mod the other one in the morning, that'll tell me what I need to know :)

my guess is that if you did the mod and you cant get over 800mhz, then it was the mem mod :P

i have also been folding on my 8600GT 24/7 @ 1836 shaders, however i have no idea how many PPD shes crunching, but i would say very close to yours :)

if you have success with the VR VGPU mod, post piccies cos im totally down fo still tryna get 1ghz core and 2.4ghz shaders out of these babies.

[Skitzo]

well, there was power making it through the vr for sure. When i crank the vr to 0 ohms it trips the card(it'll go as low as 2-3k ohms). This system is on a table and not in a case so I've been experimenting with grounds. So far the ground pin for the fan seems to work, I'm assuming it needs to be set at 100% though(fan) I should have checked the gmem for oc but i was concentrating on the gpu so I overlooked it. I'll have a go at the second vr mod in a few hours and let ya know how it goes. I'm basing my vr mod on the other pcb vr mods. Should be the same pin on the same chips, the chips are just in diferent locals.:)

[Solaris17]

happy overclocking, and i hope Sol can get you all pencil modding soon, just be patient, he is an 8-9 series god around here at TPU, but even gods need time to do their work :)

grave yard shift usualy 5 to 3am been getting a busy week usually averaging 9 and a half to 10 hour shifts after including breaks so. when i get home its bed wake up put on the uniform do it again.i promise ill get to them asap and excellent pics :) ill get to them as soon as possible.

Great to hear back from you, Solaris. It seems that you are swamped with your job. Good thing that they are never returning customers. :laugh:

Back to vid card, I am still messing with shader and got some increase in 3dMark score even though it's marginal. Pencil mod to increase voltage to gpu/mem would be really nice. Please let me know when you figure out something. Thanks!

[edit] Wolf, below is my new 3dMark06 result. Old: 700/840/1602 -> New: 700/840/1702 not much increase :P

3DMark Score: 6354 -> 6422
SM2.0 Score: 2620 -> 2653
HDR/SM3.0 Score: 2380 ->2413
CPU Score: 2809 with e4300 @ 3.2GHz -> 2814

Performancewise OC'ing shader independently didn't make a big difference for me. Upping the shader more than 1750 resulted in artifact/freeze. Maybe it's the limit of my 8600. Anyway thanks for your tip.

[wolf]

also the shaders clock up in increments on all 8-9 series cards, the increments are as such.

1404 - 1458 - 1512 - 1566 - 1620 - 1674 - 1728 - 1782 - 1836 - 1890 - 1944 - 1998 - 2052 - 2106

so for example if you manually set 1650 it will clock to 1620, and if you set 1660 it will clock to 1674.

if thats a bit confusing tell me, but thats definitely how the shaders clock up, the rivatuner monitor window will always show you the correct values from the card.

so for example if you manually set 1650 it will clock to 1620, and if you set 1660 it will clock to 1674.


Ah... you are right, Wolf. After manually setting up the shader to 1728, the 3dMark test was run again. It went thru without error and here is the new score.

3DMark Score: 6354 -> 6422 -> 6516
SM2.0 Score: 2620 -> 2653 -> 2700
HDR/SM3.0 Score: 2380 ->2413 -> 2444
CPU Score: 2809 with e4300 @ 3.2GHz -> 2814 -> 2819

I didn't use the rivatuner monitor before. It was GPU-Z reading. This time my core/shader/memory clock is at 702/1728/837 according to the rivatuner monitor. Note that core and memory clocks are off from the setup values but shader shows correct number. I guess the rivatuner is more accurate as you said. Thanks.

[wolf]

no worries, glad to help. i put my 8600's through hell, so im glad you can benefit from my experiences :D

i really want a Multi GPU folding client already, soon i could build a rig with 3x8600GT, that would turn over a decent amount of FLOPS imo :)

[Solaris17]

cskpeter do you have a multi meter it would be sooo awsome if you did

[lycanwrath]

Hi there Solaris,

I have taken new closer pics with better detail on the chips of my card.
Please find below:-

Do let me knw if its gud enuf, I also hav a multimeter at hand if needed.

Thx in advance :)

[cskpeter]

cskpeter do you have a multi meter it would be sooo awsome if you did


I don't have one. :(
But as soon as I get one I'll get back to you. BTW, these are the code found on the IC chips on the back of the card.
On the top right of the card
APW7067N AJ98P
On the very top left corner
RT9218 PS9LK09
Could one of these chips be the one that controls voltage to gpu and mem?

[cskpeter]

Hi Solaris,

I got a multi meter. Please let me know what to do. Thanks!

[Solaris17]

Hi Solaris,

I got a multi meter. Please let me know what to do. Thanks!

on the "back of the card" pic you posted on the chip titled RT928 their is a resistor next to it (on the right side) labled "RE8" can you measure that one please?

[wolf]

hey solaris, i just got my first 8600GTS :D, know any mods for it? its an XFX model, looks to be reference.....

from how we've done it would seem that the GTS wont really clock farther than my GT's. so i am keep to pencil mod and o/c the balls off it again :D

haha excellent i wish i had an 8600 again :( but ya the GTS's are exactly the same from what i rmember i think their was a .1v bump to allow the higher frequncy but all in all its exactly the same card.....

if you want or are ready...find her max....report them core/shader/mem and well break out the pencils...and if you REALLY want to go extreme 20kohm resistors and we will totally blow socks off that card. if your upto it send me the bios if you want and ill tweak the timings etc..

[wolf]

awesome man, legend as always :toast:

good to know its essentially the same, especially with a potential voltage increase :D

ill bung her in and find her max clocks tonight, but if i want to get serious with this card, it'll need moar cooling, as it has the stock jobbie on it atm.

EDIT: ill always have a sweet spot for a good 8600 i think.... so many memories.

Hey Solaris,

Please pardon my noob-ness but I have absolutely no experience with the multi meter. :slap: Could you please tell me if I am doing it right? Here is what I figured out so far.

8600 was removed from pc and then multi meter was set up.
Black lead to com/ red lead to v,ohm,mA
function switch set to 200 ohms (We are measuring the resistance, so I figured the switch should be set to ohms. Other numbers 2000, 20k, 200k were off the range)
test probe tips touched on both ends of "RE8", I mean literally, not on the board but on those tiny little metallic ends of the chip)
The numbers were not consistent at first but finally reached 02.5 after numerous attempts (I am reading exactly as it shows) but I am not really sure the range/number is correct.:shadedshu

Appreciate your help. Oh, I am right thru the summer semester which gives me the h3ll of lifetime. So please excuse my late responses. Thanks!

Hi Solaris!

I'm new here. Please help me. I just Bios flashed my xfx 8600 gt with 1.34 volts. I'm now able to cross 780 core and 950 mem. Need to check for stability. Before bios mod mine would not even cross 620/820. Can you please tell me upto how many volts I can set in BIOS without damaging the card?

Thanks

First off Welcome to TPU :)

Im not sure what happened for you dvijaydev46 however changing the voltage in bios does not actually alter the cards voltage, makes me wonder why they even include the option... i have tried this on at least 4 nvidia 8 series cards, to no avail.

weird that you were able to clock higher....

in the odd case that it has worked for you, id say on air cooling do not exceed 1.5 volts, however still go up in increments, ie 1.35 -1.40 - 1.45 -1.50

Need to check for stability

"ATi tool" artifact scan is great for that, also personally i like to run "Nvidia Geoforms" for at least a half hour to test gfx stability.

also what do you use to overclock, as "rivatuner" is totally the shizz.

i know solaris is THE man, however you may consider me one of his "cronies" as i am able to help you with the bulk of your 8600 questions, after all i have owned 5 of them :) (still own 3)

[dvijaydev46]

Thanks a lot Wolf. Yes I read all your posts too. You are really great here. I use Rivatuner for ocing and ATIToool to scan for artifacts. I actually scanned for artifacts with atitool. You know what I could OC my 8600 gt to the Rivatuner's limit. It looks stable with ATI tool but not with 3D mark loop. May be I need to find out stable OC for that voltage (1.34) again or increase the voltage to see how it goes. Last night it was 2 when I was doing all that stuff so went to sleep and now at office.

"changing the voltage in bios does not actually alter the cards voltage"

May be you are right, but why then Solaris was talking about BIOS mod here? I don't know but BIOS flashing seems to work for me. I'll get back home and put some screenshots of GPUz.

Thanks again dude.

not a problem.

i find that flashing new clock speeds on a card will extend rivatuners limit, and even give you more overclocking potential sometimes, however ive never heard of a 140mhz core speed gain, good work :toast:

thats usually why we talk about bios mods, once you find a nice stable overclock, you can flash those clock speeds onto the card and never have to run your overclocking software anymore.

also kudos for reading the whole thread before posting :p not everybody does that first, and you can come across as a dick if you jsut reply "read the whole thread first n00b" :laugh::laugh:

[dvijaydev46]

That's right.

Ok I'll flash new clock speeds tonight and confirm if it extends Rivatuner's limit. One more thing I had to say was that when I tried 3D Mark 06 with it gave around 5800 and the OC result was almost the same. Increased just a few tens. Could it be a processor bottleneck? Mine is 4200 X2 slightly OCed to 2340 from 2200 stock. Will try games and post tonight.

[wolf]

3dmark is very graphics sensititve, if you overclocked the core from 620 to 780, i would expect a gain more noticeable then the score only going up tens. id estimate on your setup you should get at least over 6000 points if stock gets you 58XX

[dvijaydev46]

That's a bad news. I'll check again tonight.
Thanks

[wolf]

some overclocking reults on the 8600GTS i got today :D

it appears to be an overclocked XFX model with stock clocks of 720/1566/2180

so far on stock cooling shes humming along at 810/1782/2400, and im not sure i want to go further without upgrading the cooling sitcho

[dvijaydev46]

that's cool

ahhh me to honestly since the 8600's release im going to have to admit 8600-GT280 9600 etc included i think in all honesty the 8600GT was THEE best nvidia card of all time....sooooo easily moddable absolutely can it 1ghz adjustments tweaks modifications lap jobs etc easily the most fun card to work on when oc'd and tweked in all honesty i was breathing down the necks of the first gen 8800's when i modded mine...not to mention sli...est scaling card EVER i simply love the card i want to get another i will someday....trophy card imo a hge peice of nvidia history. at any rate memory relapse over...if you lap the cooler wolf and mod the fan to run 100% she actually stays pretty cool. i used 2000grit for like 45min and made it BEAUTIFUL with some mx2 or AS5 mine would load around 55ish including pencil mod. However i have some slightely bad news anything over 900mhz wouldnt cut it. once you get close to 1ghz the cooling requirments become insane. youll probably need to do hat cdall dd an mod like a P3 HS to fit thats honestly the only thing i can see doing it.

its because in my experiance when you bump he voltage in bios though it actually doesnt increase the voltage it seems to get rid of OCP and OVP problems ;)

you have to measure it while its on ;) while the computer is on and the card is plugged in measure the RE8 resistor using the "DC volts" etting make sure that your black (ground) probe is touching yor case....Dont touch the resistor with it...only touch the resistor with the positive end.

[Scrizz]

the 8600gt will remain in my memories aswell.
Freaking sweet overclocker!

+1, best overclocking card i have ever owned. to get from a stock core speed of 540/1190 to 850/1836 - 100% stable is just magical :D

remember give him time folks, this man has alot of work to do!

[Solaris17]

Are these pics any good Solaris? Am still waiting to volt mod my 8600GT :(

their all kinda too blurry for me...however i was able to read the marks on "chip 1" and your inluck that would be our VGPU chip so can you get me a close up of the surrounding area relatively clear?

[ramo_din2007]

hi Solaris.

now i have a xfx 8600 GT XXX edition. I know it have a G84 chip. i would like flash it to 8600 GTS. now with riva tuner i have core/shader/mem 680/1500/880 with no problems.

you know, only change the label to 8600 GTS.

thanks.

[Solaris17]

so youd just like it to show up as a GTS? would you like the GTS clocks to be flashed as well?

[ramo_din2007]

so youd just like it to show up as a GTS? would you like the GTS clocks to be flashed as well?

yes, I would like to change the label to 8600 GTS with the clocks that i have now. 680/1500/880 core/sh/mem.

I tried with the bios of the xfx 8600GTS, but didn't work. why??
i used a bios with the same memory, brand and all.

[cskpeter]

Thanks for your instruction. I learn a new thing or two everyday. :p
This time VDC shows 12.15 and I hope that's close to what you expected. Let me know what you think.

[wolf]

you can have it boot and say 8600GTS, but it will not show as a GTS in any other areas. yes they are both G84 chips however the cards themselves are quite different.

GTS cores are binned higher, ie the better ones got to make GTS cards.

GTS cards have considerably better memory chips on them.

GTS cards natively need a 6 pin pci-e power adapter to work which can change the dynamic of the card.

your best bet is to dump the cards current bios, write your new clocks in "680/1500/880" and make a boot signon that says the card is a GTS

[ramo_din2007]

ok, I'll do that.

why it can't mod the bios for only change the model of the vcard? only is a label, what's the problem?

maybe with a editor software in binary code, i don't know.

thanks for all.

you need to mod all feilds. all 3d settings not just one. uninstall/reinstall the drivers after. it works you just need to trouble shoot calm down

[Wyshniukas]

I have just installed my 8600GT with AC Accelero S2 + Noctua S12-1200RPM. Tried to do the OC on memory first, as a n00b I just used ATITool Find Max Memory & Core button and came to this point http://www.techpowerup.com/gpuz/knbf8/. I done 3D Mark 06 test and VGA went stable without any artifacts or bigger glitches. How come DDR2 went over 2GHz limit? My 85GT was stuck at 520Mhz?

[Solaris17]

WTF?!!!! hmmmm idk gpu-z fkd up with me once....ill need you to answer a few questions


1. have you volt modded the card? if so what voltage?

2. sometimes the nvidia drivers screw up. Do you have riva tuner insalled?

3. if you have riva tuner installed in the monitoring window does it say thats what the clocks are?

4. how hot is it idle at those speeds?

5. what is your 3dmark score? with those speeds it should be over 75xx

4. Idle 49 with open Antec Nine Hundred case.
5. Sadly only 33xx @ 1280x1024.

Can it be the nVidia drivers buged?

i absolutely think so....he nvidia driver monitor [with the bar graph recording clock and temp] that says the same clocks as gpu-z and ati tool? the driver can bug things up i rely on the hardware monitor in rivatuner because it reads directly from the pll. if the hardware monitor is reading those clocks either the driver is totally fkd or its idling at that but clocks down during 3d load. I dont wish to discredit yu in anyway...if those clocks are real ill give you a trophy but i have beat my card to a pulp worked on my buds and aided many people here with theirs ...and the score and heat output dont ad up...i lapped my cooler got it extremely cool 38 at idle at like 800mhz but on load it would sky rocket 70's plus...at 800mhz though its possible youd almost absolutely need way better cooling than that...to be able to pull it off stabily.

I'll try to downgrade drivers to older version, as they worked better with my 8500GT at the time. Will update the thread asap.

[Wyshniukas]

Downloaded 177.79 drivers & it seems previous were the problem. With new ones, I can reach 702 core, 445 memory with nTune GPU clock test & idle temp now is 45...haven't pushed more yet, but will do it later. This is my VGA, any suggestion which manufacture to look as the example? It's Xpertvision TD51-PM8K86

It was nice to see GPU-Z validation with 800% OC thought.

Hmm, hw abt such a guide for 9600 GT?
This guide for 8600GT is really very nice Solaris.

Cheers :)

[fitseries3]

i need my 8800gts to run a 9800gts bios.

we will have to make one though. need to combine the 9800gt with the 8800gts

there will be a 9800gts sometime soon but no word on when.

[Travelman71]

Hi guys, Sol great thread bookmarked it a long time ago but i have a question, why is my 8600gt clocks dropping to stock when i run an artifacts scan with ATITool and when i run a game? I was thinking of doing the pencil mod and lapping the cooler so i started to remind myself of the things i needed when i noticed. please dont tell me i never edited the bios right in the first place :banghead:

that may be it you may have edited the 2d clocks and left the 3d clocks stock which would explain your drop :)

[Travelman71]

wow that was fast, no got all 3 lines of clocks to my desired setting 640/1500/800. poor oc i know but i dont play many games

[Travelman71]

[Solaris17]

ok i renamed it to .zip as well change it to .rom and try it..if that doesnt work uninstall your drivers and install the 178.24 drivers (or 180.10 if your vista x64) and try again ..also make sure you have the latest rivatuner ati tool doesnt play nice with the nvidia cards some times.

[Travelman71]

thanks a million Sol, i will flash it later and see how it goes, off to watch the formula one 6:10am here Scotland. I will let you know how it goes, Thanks again

[Travelman71]

Ok i flashed my card with the bios you edited... no change then got the drivers nv_177.98_Win2KXP_CD124 which opens up to be 178.24 (uninstalled originals) and then got ATItool 0.27 still no change except ATItool now changes to 0.00 clocks when i scan for artifacts, but everest shows as going to 540/1188/700 any ideas ?? what have i done wrong ?? :respect:

[Solaris17]

uninstall your old drivers and get these.


178.24 (http://downloads.guru3d.com/Videocards---NVIDIA-GeForce-(XP-32-bit)_c10.html)

xp x32 i presume?



those should work but make sure you uninstall the old first. if these dont work install riva tuner


2.11 (http://downloads.guru3d.com/download.php?det=163)

use that to OC it doesnt come with artifact scanning but it might work better than ati tool for obvious reasons

[Travelman71]

uninstalled the drivers rebooted installed the drivers from your link rebooted and its still the same with both ATITool and the game Portal and Brothers in Arms - Hell's Highway ( still dropping to stock clocks ). You seem to be going down the driver road, so was thinking would it have anything to do with my monitor driver?? i actually have a 32" tv 1366 x 768 showing up as plug and play monitor, so no driver. I do get flickers when i open a folder with thumbnails. Or would changing the bios to a 8600GTS make any diffrence ??? Thanks again for taking time to help me

sry man i have to go to some kind of engagment cerimony but ill be back later tonight. your monitor driver wont be doing it. i need the 8600's temps and you should install riva tuner i really think its an ati tool problem (prolly with the new drivers) and rva tuner will tell you what your clocks are in real time and with a bar graph it might be throttling because of heat but im unsure because the bios settings are correct. ill need to speak with you about it later but i gotta jam i need to be in Massachusetts in 2 hours.

[Travelman71]

ok been playing with Riva Tuner and set it to start with windows etc, but i notice that when i change the clocks in riva as soon as i apply the setting the clocks drop in everest to stock then jump to the right setting , and still drops when i play a game.

[Solaris17]

check the rivatuner hardware monitor its the second drop down arrow then the button all the way to the right. something else seems like its controlling your clocks

[Travelman71]

Riva hardware monitor is showing the drop in clocks too when playing a game. GPU temp is 48 idle then 63 under load. I think a clean reinstall of xp is the way to go if you dont have any more ideas?

in all honesty i am completely out of ideas....i even modded your bios so the start up clocks (which are usually lower) are the same as your over locks' just incase it was defaulting back and i cannot explain the drop is speed.

[Travelman71]

awe well clean install it is ... its about time for clear out... i will let you know when i get it working and give you a shout before i buy my next card.
thanks for helping

yeah sol, how's about a guide :D j/k

so is this still your favorite gpu for oc'n Sol, have there been any new impressive oc's?

Well i'm new here, tho i have been following this thread for the past couple of days.

Config :-

MSI 975x Platinum Power-up Edition
Core2Duo E4500 @2.2 GHz OC'd to 3.09 GHz - thermalright 120 ultra extreme
Team Group RAM 2 GB kit
XFX 8600GT (540/1138/700) OC'd to 645/1450/900
250GB Seagate 7200 RMP
500GB WD Caviar 7200 RMP
LG DVD writer
Antec Truepower 450 Watts
Antec P180 Case


Following Sol's guide, i lapped the HS on the stock cooler and also removed the gasket plate around it. The stock HS has 4 rubber legs that keep the HS of the components on the board. On looking real close , i noticed that the 4 support legs were well above the PCB due to the HS coming in direct contact with the gasket around the GPU. Also noticed that the gasket is slightly higher that the GPU, resulting in a "not too good a contact" between the HS and the GPU... doing so gave me a 5C drop in temps. where as the GPU used to idle at 54C, it now idles at 49C.

With the above specs and OC, i scored 6090 3Dmarks.

though i want to push the card higher, am reluctant to do the same without proper cooling. So will push the card more once i get my Thermalright V2.

However i did test to see how high i could go on the core. (i use ntune to test the GPU OC ,as it does the same on the fly, and use rivatuner to set the clocks)

using ntune, i was able to get to 780/1450/900.

I am not sure of the stability as i am kinda worried about the temps. With 645/1450/900 , the GPU idels at 49C. when playing games like FarCry2, COD WaW, etc the temps go right upto 77C (too hot).

I have not modded anything on the card except for lapping the stock HS.

Will upload a few pics of my rig later.

Sol..... ur guide is real neat.....though am pretty scared to do some of the stuff that has been done......Thanks !!!

thanks man im glad you liked it BTW your hot but not to hot id start getting worried around 85ºC

Well Sol :) , i kinda took your dare and benched on 725-1475-900 without any problem. The max temp when playing COD WaW was 80C. But mostly the temps were hovering between 77C-79C

Attached is a screen shot. You will notice that my CPU-Z show the CPU running at 1.6 GHz...have disabled speedstep, but it does not seem to work :shadedshu



Tried to bench at 750-1475-900, did not get artifacts when scanning using ATItool, but graphics went wierd when running 3Dmark and the comp froze....

Have a question for you, in the BIOS, my default VGA voltage was 1.5, i increased it to 1.65 and i think i can go right upto 2v....will it make any difference if i increase the voltages from the BIOS ? or , will the increase in voltage only happen with a pencil mod or a resistor ?

no the voltage wont change in the 8600's the only reasoin i do it is because when you raise the voltage in the bios and then volt mod the card it seems the card takes the voltage easier...as for your CPU at 1.6ghz disable speed step and C1E in your bios :)
