Interesting issue. I have vdimm set to 2.28 in bios or roughly around there. It reads 2.8 in windows with the uguru utility.

When I run orthos on blend test it varies between 2.28 to 2.26 to 2.22. This doesnt seem right at all. I know most boards have a vdimm droop of a little like .01 maybe but this is really bad.

Anyone lese having this issue.
