7970 Ghz issue with C3

Post » Fri Mar 08, 2013 11:54 am

Hi,

Unfortunetly in C3 it can't maintain my default or oc core clock speed, it will go anywhere between 600 and default (1050) or oc (1135) during full load even if power slider is maxed out. Anyone have the same problem?

i am having the exact same problem, i have the 7970 reference though, bios flashed to GHZ, when i run it at 1190/1820 @ 1.25v i can play normally, but at random times, the clocks go down to 500/900, and i get like 1-5 fps out of the game, until my system fails, and i have to restart. The same is happening at 1050/1500 @ 1.25v, however it happens not that often. It's pretty annoying. My power slider is also +20. I would really like to know what is causing my card to downclock and never clock back normal clocks again until i restart. It is only happening in C3.


Edit: Also you should check your VRM temps, when those are too high, the gpu will downclock to not get damaged. Peak temps may be up to 110°C on those. However if they are >100°C for a long time you may want to get a better fan. Mine are at ~78°C max after 5 hours of playing, so vrm temps are not the reason why my card clocks down. However maybe this is your problem. With programs like gpu-z you can check your vrm temps.

I just installed the latest verison of gpu-z but only temps that are displayed are of the gpu.
