I've got an old Intel Pentium II 350MHz, and would like some advice on how to over clock it (Sorry Larry, I know you don't approve. But I just want to play around with it, not bothered about it blowing up or data loss!) The two options I've got in the BIOS are frequency ratio (presently 3.5) and CPU Bus Frequency (presently 100). Which one can I change, to try and make it faster?
