GTX 570 throttling at stock speeds?

[Reptile]

Hey I might as well post this here too. Copied from OCN thread:

So I bought a EVGA GTX 570 Superclocked about 2 months ago when I put together my Sig build. I was doing more CPU overclocking and never really did any GPU stuff. Yesterday I received a second card to set up as SLI and I noticed one of the cards was throttling while running furmark -600mhz.

I removed them from SLI and both cards throttle at least 400mhz but the temps never go above 78C. I have changed the settings in the nvidia control panel for power management to prefer max performance for power management mode.

Is there a setting or something I am missing? I was told these cards shouldn't throttle until 85C

Thanks,

Ben

Edit: also I have removed and reinstalled latest drivers and did a clean install


Setup is:

Lian Li A05
i7 3820
Asrock Extreme 6 X79
Samsung low voltage ram
Corsair HX750

Try the previous drivers. The 301.42 release seem to thermal protection set to kick in and reduce clocks when it exceeds 70c. Hopefully they will get it fixed for next version.

I hope so too. Running a single card right now with no issues so far.

the current driver has some issues when running SLI, revert back to the version just before 301.42
