    K, good luck!

    You may just need to settle for using one kit

    I'm trying to sell my OCZ kit..

    Anyways I used your recommended settings.

    The Refresh to ACT delay must be 74?
    Also I used +0.15v in the MCH Overvoltage control - Isn't 0.2v too much?

    With 8GB you may need it to be 82+ actually.

    For MCH Voltage with 4GB you may need +0.2-0.3, so ).2-0.4 would be expected with 8GB, but you may be ok with 0.2-0.3

    Then why isn't it a good idea to set everything on auto in the voltage section? Because I never used to raise voltage values when I had 4GB, it was on auto and I had no problems.

    P.S. - I raised the Vcore to 1.32500v from 1.30000v

    Because auto sometimes overvolts things much more than needed, and sometimes you might not realize it.
