Overclocking The 8800 GT

Despite already being overclocked from the factoty, before we concluded our testing, we also spent some time overclocking the GeForce 8800 GT cards using the GPU core and memory clock frequency sliders available withing NVIDIA's Forceware drivers when nTune is installed.  After some experimentation, however, we found that all three cards overclocked to very similar levels (within a couple of MHz of on another), so we've included only one overclocked result here.  Please keep in mind, your mileage may vary.

You've Gotta Love 'Free' Performance

To find the GeForce 8800 GT'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, or until our test system was no longer stable.  In this particular case, we never saw any artifacts, but the test system would freeze almost immediately after launching a game.

When all was said and done, we hit a stable 725MHz GPU clock speed with 2.08GHz memory.  While overclocked, we re-ran a couple of high resolution benchmarks to show the performance gains offered by the higher clock speeds.  Because the cards were already significantly overclocked from the factory, however, we gained only a couple of frames per second in both tests with our somewhat higher, final overclocked speeds.
