[Official] AMD Radeon HD 7950/7970/7990 Owners Thread - Page 380

post #3791 of 38701
So tomorrow morning I'm going to be purchasing a 7950 to replace my current GTX260 (yea, tell me about the performance increase I'm going to be getting, haha). I really want the Twin Frozr III but it isn't available yet, and if it isn't available by tomorrow morning, I'm probably not going to wait any longer. I've already been waiting about 3 months waiting for some big news on Kepler and can't wait anymore. Probably just going to pick up the OC version of Sapphire's card. Can't wait.

Hmm, still can't seem to chase down why my core voltage is increasing even at idle after I make any changes in AB. Not a huge deal, I guess, but I'd prefer my card not be running at .949 mV even at idle. I did try assigning 2D and 3D profiles, but that didn't rectify the problem.

Did you turn ULPS off? Just wondering if it could have the side-effect of affecting all power states.

Yeah, I did the reg edit to disable ULPS. I did that a week or so ago and just started having the idle voltage issue in the last few days.

Would I want mine to run that hot? Absolutely not. That's what they're designed to run up to though.
I wouldn't worry so long as you're below 100*C on the VRM's.

The non-refference models such as the XFX DD runs pretty hot on the VRM about 120c.
The reference designs only go up to about 91c.

Just remember.... with these cards, the lower the temps, the higher the overclock...
For example.. you could have a stable OC at 75c but at 80c you will crash.

These cards are monsters, but sadly... their drivers are fairys mad.gif

I just hope the upcoming drivers for HD7970's will be much nicer and all...

What program can I use to test for GPU stability? I remember having one for my last rig that would heat it up and it told you to look for little yellow artifacts and if you ran it for a sertain time and none popped up you were good to go.
