ok did a few measurements and they all seemed to be off by about the same amount for load and idle. I set the ref voltage to +0. The highest I read and left my ram at was 2.250 set (in bios) which read 2.250 via bios. This gave me via multi meter idle= 2.279-2.281 and load=2.286-2.310. uguru read 2.24 the entire test.

A pretty big variation I think but not sure how it compares to other boards. I guess it would only be bad if you were running say 2.4 thinking thats what you were getting but the load would probably be more like 2.45 or higher
