The Inq overclocked the Intel Core 2 Duo X6800 to 4GHz and ran some benchmarks while overclocking the chip:
Just for the sake of trying at that stage, I upped the "burn in" setting to 25 per cent instead of 20 per cent. This gives exactly 1.333GHz FSB and 4GHz CPU rate at this level. Windows loaded, passed the boot window, but froze at the user login screen. After a reset, upping the MCH and FSB voltage by a notch, and five-minute power-off rest, Windows did load to the main screen, and show the correct 4GHz clock with temperature of 46C! Tried to run Sandra, the benchmark run the integer part fine, but the FP part looked lower than usual - could it be throttling?
