Overclocking Performance
During the editor’s day that I attended to discuss the 8800 GT and graphics board, NVIDIA more than deliberately indicated that we should attempt to overclock these G92 GPUs in our testing.  Of course we had to give it a shot, and our results turned out to be pretty impressive.

Here are our stock clock speeds of 600 MHz core and 900 MHz memory as shown in NVIDIA’s nTune application under Windows Vista.

After just a few instances of overclocking and stability testing, I was able to push the clocks up to 700 MHz core and 1000 MHz memory frequencies.  That is a 16% increase in the core clock rate and 11% increase in the memory clock rate using standard cooling and voltages.

The overclocked card had no problem running 3DMark06 or playing some games, and though we didn’t have a 3DMark06 results page for this review I can tell you the stock score with the 8800 GT was about 10,400.  That gives the overclocked card a 12% or so performance gain even when running at the 1280×1024 default resolution.

These numbers are certainly impressive and I think this will equate to some highly clocked cards from manufacturers like BFG Tech, EVGA and XFX when they have time to test the card for themselves.  Unfortunately, since these cards were hurried to market by each vendor, only stock speeds are going to be available for at least a couple of weeks.  Of course, that doesn’t mean you can’t do the overclocking yourself!
