Strategy

The Pentium II Deschutes 300 MHz offers great potential for those with 100-MHz front-side-bus-capable motherboards. The 4.5× multiplier of this processor can overclock to a phenomenal 450 MHz under the right conditions. In any case, 374 MHz should be possible for systems featuring older 83-MHz-capable motherboards.

Successful 450-MHz operation requires substantial cooling. A voltage increase to 2.2 volts (from the core default of 2.0 volts) is needed to attain a stable overclock. A 65° Celsius temperature limitation was imposed by the early Deschutes revisions; thus proper thermal regulation is a dominant concern when pushing core speeds beyond the 400-MHz level. Using radical cooling technologies, like Peltier or forced liquid, in conjunction with increased core voltage levels can produce overclocks of more than 500 MHz for Pentium II Deschutes 300-MHz processors featuring quality Level 2 cache memory.
