OC Team Italy has successfully overclocked a Pentium 4 631 to 8.18GHz. OH MY! Since the multipliers are locked on this processor they had to bump the FSB all the way up to 545MHz. A 173% overclock.
This is pretty amazing, I just wonder what they used to cool it. I am always fascinated by overclockers, I was into overclocking for a little bit when I first got into computers but then I killed a processor, that ended all the overclocking for me.
