    2x2GB needs some added MCH voltage

    So you will have better luck once you Manually set your ram voltage to 2.1 and then add +0.1 or +0.2 MCH voltage

    @ wtb4ghz
    If you want some help make a thread, you should not need that at all to boot at 4Ghz, you likely just need some other things adjusted rather then trying to add CPU voltage

    Ya, I mean add more. Did you already add some? If so how much? I believe 1.6 would be the max, but you would likely only need 1.4-1.5

    2.00 or 2.40 (1120 so it may not work) for your ram Mutli

    Or use 8 CPU mutli and 500 FSB and set Ram Multi to 2.00 1:1.

    Or 8.5 CPU and 470 FSB ram Multi to 2.00

    Hey, ya know 9x467 is 4.2 right? I know you said 4.2 above, just wondered cause you said 4GHz just now though
