NVIDIA thermal throttling removed!!! Higher Scores!

[railer]

I think I found the way to remove the issue we have with 6800 series cards. As most of you know while benchmarking the card would drop the core clock and this would result in lower scores. You can see that with RivaTuner monitoring. Most of our card would do that no mater on the cooling used. Now when you will apply my technique and the OC would be too much for your card it still will stutter so there is no cure for that you need to know it’s limits.

But it would not drop the clock. I gained as much as 300+ points in 3dmark05 by doing this. It’s is extreme way and probably not suitable for 24/7 operation like gaming ext…. But for benchmarking it works. Why my 6800GT is #1 place on orb ?
Because I run the benchmark @ speed I set not 1 MHz less. You could have your card clocked to 500+ but that really does not mater since it will drop the clock to whatever safe settings it programmed too if you put the card under stress. I found out that this protection kicks little bit too soon .

That #1 spot for my 6800GT will change probably soon since I’m releasing this and others can take advantage of this simple yet working solution. Oh well it took me a while to find this workaround so enjoy.

Here is how it all happen

We all know that thermal throttling is a big problem for NVIDIA cards. Now after a long while i think i figured it out how to disable it. It is an Extreme way but it works.

It began while i was benchmarking and monitoring my card with RivaTuner monitoring tool. I always notce that when the card would get to hot or would think it has to much work load it droped the clock. Even whith realy cold temps this problem stand true. Now i noticed that whenever this would happen the card would drop the CORE clock to 421 .

And then it hit me :thwack . The NVIDIA GOD came down and has spoken to me :respect: 421 was the default bios seting i was booting from. My bios was set to 421/1160 as a boot speed
So the card would throttle to safemode setting i.e the lowest setting it knew by the bios. So then it got obvios to me that if perhaps i would make bios with the max speed i knew my card can hadle then it would never drop the core bellow that. For me 100% safe setting was 472 on the core. So i made the bios that booted from 472/1200 3d@1.5v .

Did it work? Oh ya it did. :danceshee !!!
The proof is my 3dmark score . On the same 472/1350 that i benched for a while the card scored way more. I'm including a pic of RivaTuner monitoring and you can clearly see that while i was benching 3dmak2005 game2 it droped the clock from 472 to 421. Now i does not happen anymore. When i bench it stays rock solid @472 .

This is great yet simple find couse i bet most of Nvidia's here while benchig experince this problem. Why dont you guys benchmark 3dmark2005 @max your settings and enable RivaTuner monitoring i bet you will see your core drop. Give it a try

[FallenAngel]

what bios editor did you use

[Kanavit]

according to the attached pic, your core clocks still read @ 420mhz?

[kryptobs2000]

I asked if this would work, and I was told it wouldn't, I can't find the thread so I'm not sure of the reasoning. Can anyone else confirm this?

[FallenAngel]

according to the attached pic, your core clocks still read @ 420mhz?

If you see the time you will noticed that the core was @420.8 at 07:56:03 and one 1,5s later the core was @472.5

but then again how's that possible?

[FallenAngel]

...

[kryptobs2000]

420.8= 2d clocks 472.5 = 3d clocks?

he opens rivatuner in 2d, so it's going to show the 2d clocks of course right?

uh...i played around and got some not so good results on my own. If you look at my drops in core to 399 (default 400) and then back to 506, this is when I am opening, closing, then reopening the real time HDR proggie.
When I start the 3d app, the core is set to 506, but goes back to 399, so I close it, quickly reopen it and its at 506, this could be repeated consistently. Very weird.
My core never dropped though, when I was already running the app, it would either run 399 or 506, no drops. It only changed when opening the app.
Take a look at this shot.
edit: did that make any sense? sorry....

[kryptobs2000]

I don't what your saying. You have the core set at 500, you open the 3d app and it drops to 400? So you do what... I lost you after that. When the 3d app is closed the clock rises to 500 or... when it's open it rises? Also, try something that is fullscreen, maybe it dosn't run at the 3d clocks if it's not fullscreen. I mean, it's 3d and 2d since it's in a window, so that causes confusion to me. Just run 3dmark or something.

edit: Your temperature dosn't seem to ever go much below 35c so thermal throttling shouldn't even take effect, whats the problem then? uh.. well on second look, I have no idea what the temp is reading because that scale has too wide of a range to beable to read it accurately.

edit again: Ok, well the temp line never goes below the second green line. The graph goes in incriments of 25. So that means it didn't drop below 25c for sure. And thermal throttling dosn't matter unless it drops to 25c. So you shouldn't even have an issue with it. I think your only problem is it's getting confused and switching from 2d clocks to 3d clocks because it's being run in a window.

[railer]

ok the point here is that the clock would drop and there is nothing you can do about it. Say if it drops to 400 while benching it will stay there untill the app is finished.

The only think you can do Drcrawn is to create a bios that starts 500/1200 and boot from it. This way the card dont know anything lower then 500 so the drop below is imposible. It's not practicle couse i cant emagine you would want to run your card at that speed but it will work for benching. I use OMNI editor but it realy dont mater all yo need to know is how to make bios and flash

Be careful thou couse there will be nothing there to save your card if 500 is to much for it. If to much workload the card can burnout. So what i'm saying is make bios with stratup setting you sure it can manage. In your case id start with 480/1200. The ram never drops and you can clock it to 1316 and it will stay there.

[kryptobs2000]

yeah I see your point, I get everything your saying. I don't see a problem with this. You can set your 2d clocks at x/x in the bios, and your 3d clocks at y/y and it'll be fine. Yeah you can't test it easily, but once you have your stable 3d clocks, you have them right? I mean... It dosn't make a difference that you can't change them. If you have a problem and can't use your phase changer or w/e cooling gets it below 25c then just don't run 3dapps untill you flash it because it will be running at it's 2dclocks anyways.

Issue is, I'm still wondering if this works tho.

[railer]

yes you are correct but i have found that its best to set your 2d and 3d clocks same. Also this stands true for voltage . You can have diferent settings on 2d/3d but what these card do is that when that protection starts it sets your 3d clock/voltage to 2d settings. That is just the way it works. Even at defualt bios 2d is @1.1 and 3d is 1.3. So when the card starts throttling it will drop to 2d voltage. I dono it takes me 1 min to flash so i dont have a problem using 2 dif bios.

It did worked for me. I did lots of testing and each time i would bench on same 472/1350 with diferent bios the scores were in 250-300 points diference.
Actualy the way i find this out is that i had a 3dmark run with my old bios which were 421/1200 and that time the RivaTuner monitoring did not show core drop and i scored almost 300+ points. That run still stays highest with approved drivers. So after that it hit me to try this and whala i scored even higher with bios that were starting from 472/1200. It's realy easy to try for a hardcore benchmarker. I dont know about LE, 6600's cant say but it should work for 6800GT and Ultra's

[reject]

hey edfx, welcome to XS
so you gained 100 points doing this? i remeber your prevous WR was 6500 something
im gonna test this, but its pretty annoying, i change both core and memory clocks depending on the bench, even 03 and 05 have differenct maxes for me

[Skip]

how did you edit the bios?

[drcrawn]

Kryptobs you are correct about the problem identifying 2d/3d for that windows program...weird I ran Halo multiplayer for a bit and then shot a screen of riva monitoring, everything worked as it should have. 2d @399/1104 (apparently, lol) 3d @506/1.3

no need to set 2d/3d volts the same 4 me, and no where near cold throttle temps
already flashed to 1.5v @3d

u can get omniextremeedit at mvktech dot net

[kryptobs2000]

I don't care too much about benching. I usually only bench my stable system anyways. So this is really good news for me, I was thinking about phase cooling my 6800. Thanks for figuring this out railer, I had thought of it before, but I was told it couldn't be done. Props to you

[drcrawn]

railer, two questions: in the pic of your riva monitor, when you say it drops the core (throttle) to 421 your core temp is 19c, but when it is @ 472 your core temp is 10c, that seems weird to me...why would it get 9c hotter when its throttle to lower core speed (and presumably voltage)?
Second: is your max benchable 472 core with 10c and 1.5v?

[EnJoY]

It could have been at his max clock at about 20c and then throttled to 425 and when he took the screen, it may not have cooled down yet.

[reject]

ok i found out some wierd stuffs
sure enoguh that was happening to me.
so i tried forcing 420 core with the bios
screen 1
then i went down in 5mhz steps, till i got to 410 whre it was only minorly artifacting
its very interesting particulaty core temp

[kryptobs2000]

could just be somekind of read error, the temp probe obviously has problems. Was it artifacting at 420mhz? That seems pretty low to have problems.

[highspeed]

Railer, awesome find and nice of you to share it. Have a question though, are you using a Ultra bios? Because i cant change 2d speed with the GT bios. And i tried to flash my GT with a Ultra bios but that didnt work. Got an error message with nvflash "wrong device" or something, even when using -5 -6 parameters. I heard that ultra bios also maybe have tighter mem timings and can damage your GT, so a GT bios seems safer to me.

And man you got some great GT card, 480/1350 is just crazy

I benshed 3dmark05 yesterday and i noticed your problem. When i was using 1.4 volts in 3d and runned GPU @ 430, 3dmark05 stuttered a few times and i only got 4600. Then i flashed it back to original and set the gpu to 425 and i got 5583! So it must have throttled back to 350 when i runned 430. Another strange thing happened when i tried to run gpu @430 with only 1.3 volts the computer rebooted everytime in game test2.

[reject]

gt has the tighter timings

could just be somekind of read error, the temp probe obviously has problems. Was it artifacting at 420mhz? That seems pretty low to have problems.

it was throttling not artifacting
just played doom 3 and it was all good, i was getting "program must close" errors and i realise that was the core too high @420
410 is good, but nfsu2 is a problem
i think i might have to do something to my silencer am i getting the right temps?
here is doom 3 hw monitor

[kryptobs2000]

I don't get why it's not running at 420mhz tho. Is your card just not stable at it or what? I don't see why thermal throttling would matter. It only kicks in, to my knowledge, if you clock it way too high and it artifacts alot, or if it drops below 25c neither of which your card are doing, so why would thermal throttling matter?

Will this work at 25c or less? Has anyone tested that?

[reject]

well at 415 i got way bad arts.
at 420 i just got freezes, which is worse
i benched 425 core for 3dmark05 which is more stressful, but i did have a table fan instaed of my case side panel on
428 for 3dmark 03
but at 420 it freezess on 70c, at 415 is goes past that till it arts which for me is about 76c

[drcrawn]

BTW, ppls have been using the 2d/3d same volts and clocks trick for some time now...not to burst your bubble railer...but I know lardarse/shamino and xtremetheme were modding and playing around with Ultra bios from the beginning
A bunch of 6800 users at guru3d and here have been using this approach for awhile, mostly with omniextreme edit. Personally, I use the 'backupx2' bios that VR hosted, but I believe was written by xtremetheme (who I think at the time didnt even have a 6 series card...) the only thing modded is the 3d volt to 1.5 from 1.4. 2d volt is the same. I've had no problems with this bios, although I think a lot of ppls had better success modding their own bios to same volts for 2d/3d.

could you tell us a little more about your setup railer? I don't understand a few things. For one, the first pic you posted makes no sense to me. 9 degree celcius increase in temps is ALOT especially with chilled water...that pic almost looks like you set the 2d at 472, then ran a 3d app for like one second @421 and the temp jumped to 19c from 10c. Maybe I don't understand the pic... Why would a drop in core clock cause a rise in temp by that much?
Also, I know certain chips oc better than others, but with 1.5v and below 20c temps, shouldn't you be up around 485 at least? 472 seems awful low to me with such good temps and high volt...
