    Did not try 4 GHz.

    With 3,88, I reach 74 C with Linx. That's enough for me.

    Don't forget to test your OC with LinX and monitor your temps with Coretemp.
    Please read my post here about QPI/Vtt, you may actually need 1.66-1.68 Ram voltage and 1.35-1.45+ QPI/Vtt for your memory at that overclock.

    IOH increase will help as well

    QPI/Vtt Voltage post (High is OK)
