PNY XLR8 8800 GTX OC
Before we concluded our testing, we spent a little time overclocking the PNY XLR8 8800 GTX OC using the clock frequency slider available within the NVIDIA control panel after the nTune utility had been installed. 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, or until our test system was no longer stable. nTune currently doesn't allow individual modification of the shader clock.
After some time, we finally arrived at a final overclock of 630 MHz for the core (up from 621 MHz) and 1100 MHz for the memory (up from 1000 MHz). This was the highest overclock we were able to achieve with perfect stability. Attempting to raise the core or memory frequency higher, even by 2-3MHz resulted in crashs and lock-ups during full-load scenarios such as benchmarking. Overall, we are quite impressed with the overclock we achieved.
