Whenever I trie to overclock my cpu, I will set a certain voltage in the bios and when I'm in windows my smart guardian reads a lower value. For instance, I set my cpu voltage to about 1.57, however, the smart guardian program is only reading 1.52v. So is cpu-z. Which one do I believe? Specs are in sig. Right now I'm trying to test an overclock 270 x 10, ldt x3, fsb/cpu ration of 3/4 and a cpu voltage in bios of 1.275 x 123%overvolt=1.568 or about 1.57v
