Running a PIII 500 at 645MHz: One man's journey
My friend DivideBy0 from #hocp has made the big time with an article over at the Tech Zone about his overclocking exploits. He describes how he made it to CPU nirvana, running a PIII 500 at 645MHz, and he has some good advice where to get overclocking tips. There's even a cheesy picture of him at the end.
Not to be outdone, some Aussies have pushed a Celeron 433 to 650MHz using some super-cooling tricks, like pouring an "oil can" of Fosters over the CPU every half hour. Or something like that.
