Reading at bios and cpuz always's different. It's all depend motherboard and PSU .. Called Vdrop.
But is that inherently bad? I've read everywhere that you're not supposed to go above 1.5V for the Vcore. Right now I've got it at 1.48125 and both CPUZ and CPUID report it at 1.512...should I worry about that? Maybe I shouldn't raise the voltage anymore?
