I have your mobo's cousin, and it had the same problem...it kept the voltage at 1.8, even though my RAM (g.skill like yours) called for 2.0 - 2.1.
I was getting BSOD's pretty regularly until I boosted the voltage up to 2.0. Since then, I haven't had a single BSOD.
I'm pretty new to tweaking, but I think it helps to have the RAM running at its designed specs.
Noob advice... so take it for what its worth.
