Italian enthusiast, Griff, improved the results achieved overclocking the "Bus" of Intel 875P logic twelve years after the registration of the previous record!
As recognized by the Italian, it cooled with liquid nitrogen not only the central 130-nm processor generation Northwood Celeron, but also the motherboard Northbridge . The latter had to be modified on the hardware level. The CPU voltage rose to 2.01 V, on the north bridge chip - to 2 V, on the memory - to 2.86 V.
base frequency generator was eventually increased by more than half of the rated value - up to 404 MHz. The value 8x multiplier would help raise the frequency of the base generator even more, but the author is not a suitable engineering sample processor experiment. By the way, the air-cooled Northbridge base frequency generator able to raise up to 393 MHz, so it certainly can do more under liquid nitrogen. Related Products :
