Will give working the voltages to see where that gets me first. As I stated i have seen not only higher speeds with the 860, but also with G.Skill. Unfortunately with so many variations it would be impossible to make straight comparisons to the exact model RAM I have.
I have been researching it but information seems to predominately revolve around p55 boards. I do not want to assume the specific voltages would be the same with my board... So i have been a little leary about using them as a refference point.
My logic is that if i start with a higher rate RAM, moving forward with cpu tuning should be easier to achieve with RAM rated @ 1600mhz. Not that I need it faster necessarily. I may, however, be wrong about that, but it just seems to make sense that way.
