I've got a gigabyte 7950 that's under water and I'm having some issues with what I assume is stability on my overclock. basically i can get it stable at 1200/1600 at 1.3v in benchmarks and games.. the only problem is when logging into windows the display driver will fail and what not indicating a bad overclock of course. but even at less of a clock i have seen this happen. Again, I've played games with no problem. spent yesterday playing crysis 3. So i'm wondering if this is still related to the overclock or if it's possible that something driver/windows related is to blame.
