Very strange your graphics works for 2D frequency. It shows 0 mV is fine, the condition is unlock voltage monitoring, I'd now rather not do that.
Show more: dxdiag.txt?
Just a shame that we each other did not understand at the beginning of the first page of the topic.
It's not important, but if you find a solution we will be grateful thanks.
I found this weirdness, if I leave the affinity mask for a default, I have the most busy fake core?
If you manually assign only those physical everything seems fine.
