All those years spent in engineering and chemistry and I can't convert mV...Oh if my professors could see me now.

I ended up averaging default DIMM VTT (0.94V) w/ what it is set to now at my current vDIMM (2.11V) which is 1.06V. This leads me to -55mV (-125mV seems rather low) which I am currently testing using memTestPro. If I get 200% w/o errors and Prmie Blend passes for two hours then I will drop it some more and see where it leads me.

I'm not sure what to look for as far as stability other than running memTest and Prime Blend. I just really dislike having settings left on auto and if I can lower voltages while keeping my same clocks than I am all for it, of course.
