Sammy Sung, you're welcome.
Betterdan, if you have a Core 2 Duo or a Core i7 then you will want to have EIST enabled, only. Especially, if you want Turbo Boost for the i7 to function correctly. You will not notice at all when it is lower in Mhz. BTW, it scales to the need. So if you are playing a game then it will be at maximum till you quit. As for AMD's power management, I think I would may agree with you, due to a bug. But it has been fixed and the chip in use may not be affected. http://www.anandtech.com/cpuchipsets...spx?i=3492&p=6
It can be a little disconcerting, but what I previously mentioned before is the thing to remember. Although, I did not mention how with Window XP you have to select a power management scheme. As for Vista and Windows 7 you just leave it at balanced. C1E is only meant for Windows 9x, and NT.
