Introduction
Quite a lot of time has passed since my last update of the Overclocking Guide and now some really important things happened, which urged me to write something about this topic.
Although I never included it in my Overclocking Guide, the Pentium II is a wonderful CPU to overclock. All PII 266 CPUs that I came across worked just fine at 300 MHz and as long as you cooled the chip well enough, they even run at 337.5 MHz, (4.5x75 MHz).
A simular thing used to be true for the Pentium MMX CPUs, even Pentium MMX 166 CPUs ran just fine at even 233 MHz after simply changing the multiplier.
