I used Gigabyte's HUD program to overclock this 8800GT. After hours and hours of changing settings, I finally found the best clock. I reached 760MHz core clock, which is a 60MHz increase over the stock 700MHz core clock. The memory clock was harder to push and the highest I could get it was 960MHz (1920) from the stock 920MHz (1840) memory clock. The shader clock was stock at 1700MHz and I raised that to 1818MHz. I was almost disappointed but then I remembered that this card is pre-overclocked so for this card to be able to squeeze out this much more is impressive. The temperatures never rose above 60C, even when I raised the GPU voltage from 1.10v to 1.20v.
