Mine is the same, not very stable after 1200, starts to artifact around 1250 & completely locks up at 1300. I can however push the memory offset to 650 without issue, but crashes at 700.Try Lowering The Memory Clock Speed To 2800Yes, i got it working...
Again, I've tried adjusting the P states (p5) using several methods, and each benchmark shows the clock is at 1085--and never higher. =\Not Sure why Your Unable To go Higher So Lets Start From The Top . We Are Going to Use Nvidia Inspector For This....
