Hi, Good argument re auto downclocking of speeds when idle. This was the first generation of CPU's which could handle an overclock and auto-down-clocking without any real problems. I had a thought this morning as I've been pushing my CPU hard in the last month or so, maybe I should profile my overclock and only use it when a certain game/benchmark requires it. So for example my CPU runs 4.5GHz @ 1.25v which is relatively low, however it's now running at 4.8GHz @ 1.36v which is a considerable bump in voltage (temps went up 2-3 degrees which isn't bad). So as I begin to push the boundaries and reach 5.0GHz then maybe I should have my default profile as 4.5GHz and only use 4.8-5GHz for a game that desperately needs it.
