ok..my vcore is set to 1.3 in bios...cpu-z displays it as 1.2...what the heck! is the droop that much on asus boards?

don't listen to CPUZ. the only real way to find your voltage when your board is doing that is w/ a multimeter. just gotta hope that bios is right my vcore in CPUZ flucuates hardcore....

Droop is just as bad on mine (1.45 in bios, 1.38 in cpuz)

Its a problem with most asus boards

That's how you figure out how to check voltages with a DMM. ZCPU is a load of bunk with their voltage readings. I'm not sure why everyone seems to take ZCPU as an infallible fact... when it's more wrong than any other reading. It's been shown in numerous tests that the closest thing to the REAL voltage is what you set in the BIOS.... then the BIOS reading by a good bit and then CPUZ and other monitoring programs by a large margin. DO I have concrete proof of this in my hand? No. But use my oh so useful link above to confirm it.

Neither CPUZ or the BIOS are always correct. Both can fluctuate a fair amount, unfortunately.

The DMM is the "best" method for accuracy, and can be used. You just need to find the right spots to test against, which (iirc) can vary a bit board to board, accessability wise. This will give you the most accurate reading, but obviously it's a bit of a pain - you don't want to have to probe the mobo each and everytimg you tweak the Vcore

thank tankguys - I am aware that it varies from board to board. Problem is - my board isn't exactly a common one. So I'm not sure where to find that spot. I know it's supposed to be near the cpu socket, but there's a lot of electrical components in that area. Don't want to burn my board .
Googling didn't help much either, since like I said this isn't a very known board.

You won't burn your board. When a DMM is in voltage testing mode, it's an open circuit between the probes - so there's no way you'll close a circuit that you aren't supposed to. No worries about burning something out with this (unless you accidentally connect 2 points on the board with a single probe tip).

You can try contacting the manufacturer and see if they can tell you, or google it. The info is most likely out there somewhere - just have to find it.

Most DMMs have an error resistance in them. Bear this in mind when measuring vcore and be prepared for the Voltage to drop slightly when you measure it due to the small error impedance of the dmm itself.
