Some quick tests to see how it works with LLC= "Standard" and looks good.

It is a huge Vdroop(compared to Level 2), Vcore= 1.30625 (BIOS set) ends up as 1.24v/1.21v (Idle/Load). But I'm keeping it, not only because stopped wining, but seams to be running stable with 2 higher BCLK

PCIe = 103MHZ, not only boots with BCLK224, but also seams to be stable roo

w3520 @4.25GHZ (224x19) 1.21v 30 min OCCT stable
