Smokin' baby!

A group of enthusiasts from Italy have managed to overclock an Intel Pentium 4 631 (3GHz) to the lofty milestone of 8GHz using liquid nitrogen to cool the CPU to less than -190? degrees Celsius.

The team of overclockers realised they were onto a winner when they managed to get the 3GHz single-core Cedar Mill chip to over 7.4GHz with an unmodified off-the-shelf Asus P5B Deluxe.

They weren't satisfied though, as they believed that there was more headroom left in the CPU. In order to squeeze every last drop out of the CPU, the overclockers modified their P5B Deluxe to give the board some more stability at these extreme clock speeds.

According to CPU-Z validator's hall of fame, this is the highest recorded frequency on an X86 processor. It's even more impressive when you consider the board and CPU were running at 533MHz FSB - that's a 166% bus overclock. We'll leave you with a screenshot.
