Way to Disable Clock Throttling on 7900GT?

[TheRyuu]

For some reason, my 7900GT keeps falling back to it's default clock speeds for "temperature problems". I have NO idea what the CP is talking about cause it's at 33 idle and 37 load (with water cooling).

Is there any way to disable it (with Riva Tuner? etc.?)?????

I HATE it, sometimes it does it when I'm no doing anything, and sometimes it does it when I'm in the middle of a game!?!?!?!?!??

Roll back your drivers to a previous version. I've heard the new Nvidia drivers do some pretty agressive throttling.

I don't want to rollback by drivers. I like the 90's series drivers. The quality and performance is great with them, and DVD playback is the best I've ever seen.

Is there any way?

the drivers are stopping overclocks, you have to roll back

So there's no way to stop it besides rolling back?

the drivers are the problem. they are clearly "beta" and i read in other forums too that ppl have rouble oc'ing them.

They overclock fine (since I'm using Powerstip) it's just that they throttle unessasarily. Can you turn it off using something like RivaTuner?

i'm guessing you're using 91.31...if so roll back to 91.28 and see if the problem persist.

No they don't O/C fine because the drivers throttle your clocks back!

LoL, wizboy11, you sound like a broken record. How many people have to tell you that the drivers ARE your problem before you accept it?

Unless you can hack the drivers you will have to use another set if you want to overclock. I noticed the same thing on my 7900GT when I tried the 91.31 driver set. But I didn't notice the better than ever DVD playback quality and performance improvements. I had no problem rolling back to 84.21 myself.

Alright, alright, I'll try the 91.28's and then if that doesn't work, I'll try the 84.37's.

The only reason my DVD's look better is you can sharpen and noise reduce from the new CP. This, with ffdshow, produced the best DVD playback I've ever seen.

Well, for everyone who said to rollback my drivers, I didn't have too.

I may have sounded like a "broken record" but a little bit of searching may go a long way. Over at Tweaks R Us, they suggested that I enable the Customize low power 3d clocks so that when it does "throttle" it "throttle's" to the same clocks. At least I get to keep my drivers

So everyone that rolled back because of that problem, ya didn't have to since there always seems to be a way around everything.

(I also found that you can disable the stupid "test clock speed" thing in Riva Tuner)

Did you run a benchmark to see if the score corresponds to the overclocked rates or not?

 

[AthlonAlien]

You can also use NiBiTor to remove Thermal Throttling from the BIOS.

 

[Smartazz]

Is this just the G71s? Because my G70 has never had problems like this.

I opened up the hardware monitor in riva tuner, played a game, ran rthdr....., 3dmark, it all seems to check out. The clocks never changed and I really had nothing to compare the 3dmark05/06 scores too, but they seemed about right for the clockspees that I had.

3dmark05 ~14,500 and 3dmark06 ~8,800

Thats for 7900GT's @ 700/1620 (obviously memory bandwidth limited) and Opty 175 @ 2.5ghz

Is that the score you got from the non-beta drivers at the same clock rates?

I don't know because I have nothing to compare the scores with. My other scores are higher except that was with a higher OC on both video cards and CPU. I scored about 15k in 3dmark05 with Opty @ 2.75ghz and 7900GT's in SLI @ 670/1920. That was when I did the memory vmod too.

I've since gotten rid of the memory vmod since I nearly killed one of my cards doing it. So I'm not sure whether to attempt it again or not. 1600mhz is stock GTX voltage so at least I got 2xGTX's...

 

[TheRyuu]

Well, raising the Opty to 2.75ghz again finally gave me 14,900ish or about 15k like I had before. Seems the trick works.

 

[Navid]

Someone used the same approach through Riva, with the latest beta drivers, and forced the card to be overclocked to the same rates for 2D, 3D and low performance 3D.

He got a 3DMarc06 score that was equal to what he got with the non-beta drivers if he did not overclock his card even though background monitoring in Riva showed that the clocks did not throttle back while 3DMark was running!

Some settings may have been wrong. It took a reboot for the new clocks to kick in too.

I just ran 3dmark05 with everything else the same (re-overclocked Opty to 2.75ghz) and that boosted the score to the same ~15k I got before.

I think it was something like 14,950. It was probably a little lower than the 15,050 that it was before because the memory OC on the video card is at 1620mhz instead of the 1920mhz that it was for the 15k score that I got.

SO, the low power 3d clock worked for me. AND I discovered that a 300mhz drop in memory bandwidth is only worth 100 points in 3dmark05

Looks like I don't have to do the vmem mod again
