It seems the "without Vdroop" option does slightly different things on different boards (which stands to reason). OC Nub's result above was +.0365 from what he set in BIOS. Mine is +.03575 from what I set in BIOS. The good part is (at least at the two Vcore settings I've tested, when stressing 3.8 & 4.0), it's consistent. So I can deduce loaded Vcore from the BIOS setting merely by adding +.03575 to the BIOS setting. Makes getting precise Vcore when booted up and loaded very easy.

Haven't tested with Vdroop. Wonder if it would have the same consistency?
