Using the latest version of NVIDIA's nTune software, we attempted to see how far we could push the Foxconn GeForce 8800 GTX's clock speeds beyond the standard reference settings. With a core speed of 575MHz and memory frequency of 1.8GHz out of the box, we managed to find a stable ceiling of 625MHz for the core and 1.9GHz for the memory. In comparison, the highest factory overclocked models using air-cooling are using a 630MHz core speed and a 2.0GHz memory frequency.
Thanks to the minimal efforts required to overclock the Foxconn GeForce 8800 GTX, we are rewarded with a solid 400 point gain over the stock configuration and a total score which is knocking on the door of 12,000 points. When we consider the fact that this performance gain comes at no financial cost or concession to stability, it would seem a logical choice for many to overclock the card out of the box for the highest possible performance.
FarCry was a title which showcased one of the largest performance differentials between the Foxconn GeForce 8800 GTX running at reference speeds and the factory overclocked model from XFX. After overclocking the Foxconn model to higher frequencies, we find the XFX model is little more than 2fps faster. Here, our overclocking efforts resulting in more than an 8fps gain in average framerate.
