GeForce 8600 GTS sample overclocked to 1GHz
Yesterday, we noticed a report that suggested the first revisions of Nvidia's upcoming G84 and G86 graphics chips couldn't clock themselves down to "2D mode" in order to save power. Whether this ends up being true or not, the G84 chip certainly appears quite apt at clocking upward. The folks at VR-Zone have appropriated one of Nvidia's upcoming GeForce 8600 GTS graphics cards, and they've managed to overclock its GPU to a blistering 1GHz (1006.81MHz, if you want to get technical). They were also able to push the card's memory to 1266MHz. For reference, the default clock speeds on VR-Zone's card appear to be 745MHz for the GPU and 1145MHz for the memory.
Pushing the GPU to 1GHz did involve hardware voltage modding, but VR-Zone kindly provides pictures and instructions for adventurous users ready to void their warranties before the GeForce 8600 GTS even comes out. The site also has a few benchmarks up: with the GeForce 8600 GTS running at 1GHz/1.266GHz on a Core 2 Extreme X6800 processor overlcocked to 3.2GHz, the test system was able to hit scores of 7524 in 3DMark06 and 15324 in 3DMark05.
