Strategy

The Celeron II 566 is a popular choice among overclockers due to its 8.5× internal multiplier. With a 100-MHz front-side bus rate, this chip offers an appealing overclock to 850 MHz with little effort outside the addition of a good-quality heatsink cooler. Some users have reported overclocking returns beyond 900 MHz with active Peltier or liquid cooling, thus rivaling the performance of the best Pentium III Coppermine models.
