    Please link to your ram.

    That CPU may not even do 4Ghz under water. For sure not likely to do much above 3.6-3.8 with your cooler. Where are you running at now?

    Try zero 0 here >>>
    CPU Clock Skew (ps)....................: <<< 50 << 0
    MCH Clock Skew (ps)....................: <<< 150 <<< 0

    And then try less MCH voltage, and set Driving strength profile to 1066

    Yes, it is in the advanced timing page. You can see here is a example of where it is >>>

    Advanced Timing Control


    Channel A & B Driving Settings


    If you do not see those pages or settings then you likely need to update your BIOS. If you do update your BIOS DO NOT USE @BIOS!!! Here is a Guide I made on how to use Qflash >>
