You're using the wrong cpu-z. There is an updated 1.57.1 something that reads the vcore properly.. Your CPU-Z is showing the VTT. I don't think the updated cpu-z is on their page since it's beta...if you use the search, you may find it, but I know a link was posted a few weeks ago in the UD7 thread.

You're right about the DVID, it SHOULD be 1.41v, since it's VID+offset, but you're also getting vdroop.

Try setting a DVID of +0.08 instead of +0.05, and see if that helps. That should compensate for the vdroop.

Of course the proper answer would be to use LLC, but seems like you can't use LLC with dvid anymore....
