    Hi Outer,

    Thank you for cheering your recipe.... Everything Went as advertised
    Some Hick up with one game who leads to some confusions..
    all sorted out....

    I also Try your setting at 3.86......there bad luck
    i try an intel burn test.... immediately crash....
    So went back to 3.6 an enjoy the moment
    untill i get the courage to Go higher

    Again Thank you

    you might get 3.83 to work if you use 2.1V for your Corsair dominator memory. My Gskill memory works at a slightly lower voltage, so maybe you could try that. Did you have it at 2.1V already?

    Bummer. Maybe if you can't get stable you can let us know some details and we'll get you sorted out!

    Could be worth a try. I'm still on F7 BIOS. Not sure what enhancing memory compatibility meant with F8, and now I see F9 removes support for a chip that had support added in F6! seems like a bit of monkey-business. I liike F7.

    Thanks Outer Marker for your configs, just to show everyone, here are my settings below. I used the 3.83 config, but had to change a few things to get it stable. Anyone with a poor E8400 such as my C0 stepping can use the template below as CPU voltage is set a bit higher:

    Dont use this with stock cooling, as voltage is a fair bit higher.

    Still running stable at 3.83 for a while now.

    Outer Marker: any luck with anything at 4Ghz?
