I having 1 issue now, and i hope i can solve it.
I've got 5970 overclocked to 900/1200 with 1.125v, everything is ok(even temps), but i've got 1 issue, this issue is crysis freezing with blackscreen, but i still can hear the sounds of the game, and i wanna to know, is this because of crappy game, or because overclocking? The only way to go back in desktop is rebooting a pc.
10.8b catalyst hotfix, 10.8 app profiles, crysis 1.2
If it passes, then your card might need more volts for 900 core.
