Hi chef. Nice to see you here as well.
I think there have been numerous post about where to measure the vdimm and vcore. In this thread actualy, I just don't have time to search for you so you go ahead and look...

I have a tip for you if you want som ekiller SuperPi.
If you set RAM to 1:1 with the setup in this picture: your image.
Then I'm sure you get half a second off or so. I have tried the difference between 1:1 and ASYNC and you really need som killer high RAM to beat the 1:1.
Actually I did not beat my own record with 1:1 even when reaching 1250MHz on the RAM.
So either you get 1:1 or you get about 1200+ to get the same result.
