Asus 7950DC2T overclocking problems

post #1 of 3
Thread Starter 
I have an asus 7950 direct cu2, it runs cool, quiet and VRM temp is also good.

However, if I put the volts above ~1.1V I get a hang after a short time (1 minute ish) with repeating sound and the monitor turns off. This happens even at stock clocks with the higher voltage.

I have this problem with multiple drivers - 12.8,12.9,12.10,12.11 betas

These hard locks seem to come at a much lower voltage than I expected, I have seen many people at 1.2V which I cant seem to achieve at even stock clocks. My ASIC quality is 83.5% and it's perfectly stable at 1100MHz/1100mv.

I'd appreciate any input - is it just that my 7950 is lower quality than these others or is there something I'm missing?

Edit: forgot to mention my PSU is a HX1000 which should be overkill for this load
