I need some help overclocking my card.. Since in the OP you mentioned most people see only a small (if any) gain in performance above 950/1150 clocks, I'd like to hit that since I'm so close. Currently I'm at 930/1120, and if I go to 940 core after about 6 minutes in GPU tool can detect errors. Once I get to 950/1150 and OCCT doesn't detect errors for 15 minutes or so I'll gladly get what I need to get to post proof to join.
So, do I need to add some core voltage to get past 930/1120? My MSI AB isn't giving me the option to control my voltage, even with unofficial overclocking mode enabled (I followed the instructions in the guide of how to OC your ATI/AMD card, but couldn't figure out how to get voltage control, so I'm at stock voltage at the moment).
