RyviusRan :
I overclocked it to 1567mhz on the core clock and 8000mhz on the memory clock.
I didn't even have to adjust the voltage and the card stays cool at 65C even in my warm room.
Nice results, but you really won't know until you test it thoroughly on some of the more demanding and less optimized games whether it will stay stable, or start showing artifacts. How did you determine where to stop your OC?
Did you push it with something like Kombustor or Furmark until you saw artifacts, then bump it back down? Just playing games like Far Cry 3 and Crysis 3 can also help test for stability, esp at max settings, max AA, etc.
One more question, can you run GPU-Z and tell us what your ASIC is?
