OCCT 1.2.0b has been vital for me in getting voltages under control and in so doing has brought the stability "DRAGON" that I've been so hard at chasing. I've pretty much found my lowest voltages with the exception of maybe some more vNB, but I already have it nice and low. Here is what I'm running right now. I'm going to run this OCCT for 12 hours and see how it does.

400x9 DDR 800 4-4-4-12
