niceguy: The one post cites higher MHz obtained if voltage lowered...Not being a techie in any sense of the word, can someone provide a possible explanation!!! Sure. Athlons produce quite a bit of heat. Lowering the voltage reduces the amount of heat. Since semiconductor transistors take longer to switch at higher temperatures, lowering the operating temperature can increase the maximum operating frequency. Of course, switching times are also faster with higher voltages, so often it pays to increase the voltage. However, I have argued often in the past that the Athlons are pretty much heat-limited at 1.2GHz (with "reasonable" cooling) and that Palomino had better lower the power consumption by more than 20%. -fyo
