I have an ASUS 7970 DC2 graphics card that just will not overclock stable. I'll run stability tests/bench mark utilitles and sooner or later I get a driver crash screen. I've tried every catalyst driver revision from 12.4 to the current 12.11 beta with no luck.
It doesn't matter what speed the ram or gpu core are set to, even a mild overclock crashes my system. It also doesn't matter what gpu tweaking utility I use, Afterburner, gpu tweak, ccc.. no deal. Crash.
I understand that it could be the gpu's bios, if so is it worth my effort to attempt to flash? Also what's the best and safest way to do so? (I'm full aware of the warranty voiding this will cause).
