So now that I have a game that actually uses my card. :D  ,Bad Company 2. I am venturing into the OC world with it. Granted it plays just fine cranked at AAx8 and AFx16 HBOA On Sync On. However, there are few times where I can see it stutter. To bad there isn't a DX11 FPS OSD app like FRAPS or something, I'd be happy as a clam if I found that as well. Anyways, I am tinkering with the clock of 950/1300. My voltage is 1.25v at this clock with a modified fan profile. (20% till 40C and then a linear climb to 45%@80C, where I level it to 60@100C). Anyways I get about 80Cish with the OC. However, After about 45min of gaming last night I had a lockup. This OC seemed stable until this point passing all my other tests. I was going to raise the voltage just a tiny bit, but wanted to beg the question to everyone. What are your clocks and voltages so I can compare.

Thanks for you info.

I believe that, but was that with stock cooling? What was the memory set at? I'd be happy with stable 950/1300.

Nice. And it's stable? even though it hits 90C? what gets it to 90C? games or a bench?
