Strategy

The Athlon K75 850-MHz processor represents the turning point in this series toward per-MHz overclocking scalability. Returns diminish at speeds beyond this range, with most peaking in the 1000 to 1100 MHz range. Wattage requirements also increase for each additional speed grade; thus cooling is a dominant concern for these higher-end chips. Expect returns upwards of 1000 MHz.
