I usually use asus probe on my asus mobo's.
While it may not give a true reading in absolute terms, i have always found it to be accurate in relative terms except for cpu temps on c2d's/c2q's.
On asus mobos you will usually see VC readings higher than bios settings at idle, and it will droop under load. I don't have your mobo, but a folding buddy reported his had a lot more vdroop (ie. V cpu drop under load) than other asus mobo's.
I generally don't use the other measurement tools to monitor regulalry with anymore except for coretemp on c2d/c2q's. I do use them to get a feel for calibration when i first build and oc tho on a new mobo i haven't used before.
