Overclocking tests
OverclockingXFX has already increased the core frequency on its GeForce 660 DDR2 256MB model from the NVIDIA-prescribed 350MHz to 400MHz. The question then remained just how much higher would core and memory go? The answer was a wholly impressive 535MHz core and 910MHz memory. Those clocks were achieved without any additional cooling directed at the card and reflected rock-solid stability, and the core speed is in excess of a stock-clocked GeForce 6600 GT's.
We re-ran DOOM 3 and Far Cry at 1280x1024 2x FSAA 4/8x AF to see the framerate benefits of the increased speeds.
The elevated clocks manage to pass default GeForce 6600 GT 128MB performance, just.
Far Cry scaling is a little different, although the benchmark results, visually, are indistinguishable from a GeForce 6600 GT 128MB's.
