can anyone help? I've got mine clocked to 1150/5300 with 1085v which runs stable through a benchmark, and roughly for about an hour before crashing. I've tried upping the voltage to counter the crash, and so far i've been up as far as 1180v and its still the same. Is this normal? i can drop the overclock back on the same volts and there are no issues... does it seem strange that it will go so far with only a modest voltage increase, but then absolutely nowhere with a large increase once i reach the 'wall' with that voltage? should i just keep on going with the voltage until it goes stable? Temps are fine, running at a steady 65 degrees. Running the Sapphire 7850 2GB btw!
also, if im correct... my FPS in Heaven benchmark has gone from 48.2 (stock) to 60.5 on overclock.. an increase of around 25%. How does this compare to most people?
thanks
