    P4 661 Oc

    Last week I got my P4 661 ES Cedarmill. I had some problems with the BIOS of the Asus P5WD2 but I got it working. I took my small cascade to my flat to test the CPU.
    First pics from today:



    Here wirh 17x multiplicator, thus higher FSB and Ram clock. The Crucial Ram only does 385mhz 4-4-4-4 with 2.3v.









    I possible I'll try LN2 next week. Thx to my friend bogi for the good CPU.

    awesome results man!

    can you do a 32Mb pi bench please at that speed?

    Would be also good to lap the cpu IHS and see if it can do any more

    Temps idle about -98° and -93° at full load.
    Vmods are VCore and VDroop.
    The Cedarnill is a little bit better than my previous P4 670. The 670 did 5,7ghz pi stable with this cascade. So this chip does around 200mhz better.
