EVGA e-GeForce 7800 GTX EGS
Overclocking the e-GeForce 7800 GTX

As we neared the end of our testing, we spent a little time overclocking the EVGA e-GeForce 7800 GTX using the clock frequency slider available within NVIDIA's Forceware drivers after enabling the "Coolbits" registry tweak. To find the card's peak core and memory frequencies, we slowly raised their respective sliders until we begun to see visual artifacts on-screen while running a game or benchmark...
EVGA e-GeForce 7800 GTX (Overclocked) = 491MHz Core / 1.3GHz Memory
EVGA e-GeForce 7800 GTX (Overclocked) = 491MHz Core / 1.3GHz Memory
We found our particular EVGA e-GeForce 7800 GTX's peak core and memory clock speeds to be 491MHz and 1.3GHz (650MHz DDR), respectively, for an increase of 41MHz to the core and 70MHz to the memory. While the card was overclocked, we re-ran a couple of benchmarks and have the results posted above. As you can see, the EVGA e-GeForce 7800 GTX's overall 3DMark05 score jumped up by a few hundred points, and its framerate in Doom 3 went up a few FPS while overclocked.
