Playing around with my UD3R which is in my 24/7 box and almost never overclocked. As usual it needs more VTT than my Asus or EVGA boards, but paired with the golden W3570 it's not too bad at 1.44v BIOS set. I wonder if this board droops VTT a lot. The Dominator GT sticks are the 1866 C7s which is why I needed 1.70VDIMM for 2000 7-8-7-20-74 1T.
