I just recently built a new system with an Athlon 64 2800+. The normal Vcore is 1.5V as indicated by the BIOS (default). But using Everest & CPU-z, it says my cpu Vcore voltage is around 1.53V-1.57V jumping back and forth. I guess the jump is because of the Cool'n'Quiet technology. But shouldn't it be less than 1.5V? I had a P4 which Vcore's also 1.5V, but it was usually shown up as 1.47V-1.49V. But then again I guess it's okay for this Athlon?
