Strategy

The Athlon K7 650 MHz processor starts the downslide in effective per-MHz overclocking. Expect maximum returns in the 700 to 750 MHz range, even when applying maximum core voltage and the best heatsink cooler. The .25-micron core architecture was nearing its maximum potential for the Athlon when the K7 650 was produced. AMD introduced only one more speed grade before shifting to the .18-micron core fabrication process.
