Strategy

Overclocking the Pentium III Katmai 500 MHz works best with the 112-MHz front-side bus rate. Unlike the Katmai 450, this model is not suitable for 133-MHz bus overclocking due to its higher 5.0× internal multiplier. Most Katmai 500 processors will reach maximum overclocking potential around 600 MHz, though many units will never see returns beyond the 560-MHz level.
