2.0 seems ok, that's what I had on when I changed the ram. I know what you're saying about the board being picky for 2133 and voltage. I have always used G. Skill but discovered that they only qualified their's up to 1866 and 1.5v. Even the Trident 2400 they say 3570 and 3770 work but on their forums they say only to use 3770 (not 3570). Hopefully another bios update may help.kpo6969 I just realized that you were able to get the RAM working according to the mushkin forum. Just curious what version of the BIOS you are running? I am still on 1.8 and thinking about updating to ver 2.
Funny thing is that I set bios to defaults, changed the ram and when I booted it up it showed 1333. There was only 1 XMP which was XMP 1.2 10-11-10-28 1T. I also changed the ram default from 1333 to 2133.
