The card probably can't run well at that clock. Lower it and see if that helps

If you insist on o/cing such a high end card, wait for aftermarket coolers.

Yep. Just like me. When I got my Zalman GV1000 cooler for my 9800GT back then, I only overclocked a lil ( 50MHz Core Increase, Shader forgotten ( linked with the Core ), and memory the same. ) Then a few days later I decided to overclock it real high.

750MHz 1825MHz 1000MHz clock for it. And it ran fine for a few weeks till I foolishly decided to remove the cooler and reapply thermal paste ( first time use idle was 42, then later became 44 and then 45 ). And I spilled a drop of thinner near one of my VRAM chips , was like and quickly wiped it off, applied the TIM, and got it back into my system. And it ran. Was relieved, but when I tried playing games, it would randomly freeze . I tried lowering the clock from 750MHz to 740 and still freeze, got it down to 710MHz and it ran fine . Kept trying ways to get it back to 750MHz but couldn't. But now, I got it back to 730MHz Might be the new drivers Nvidia came out. 195.62. . Gonna try going higher, but not now .
