Ooops. I thought turning it on automatically gave you a certain amount of added speed. So you are saying that turning it on is just like chaning a bios setting from "AUTO" to "MANUAL" and having it unlock other settings which you can then change if desired... well fair enough. It was nice to see some of those settings in the bios screenshots I saw earlier today. Independently for each core. (I'm a Linux/FreeBSD user.)

I guess it doesn't matter: if people can get 3.4Ghz-3.5Ghz with 65nm Phenoms then that is good regardless of whether it is "automatic" or not.
