    Does Time synchronize, too?

    Vcore 1.11875V (BIOS) GFlops 50

    Vcore 1.11250V (BIOS) GFlops 48

    I have noticed that when the CPU is on the edge of stability, GFlops can be a little lower than when given a little more voltage for it to be 'comfortable'.

    Not sure what you mean about time synchronizing? Time changes with GFlops - the higher the GFLOPs the lower the time.

    Very nice cpu you have got there. Can it do that using a 64bit OS and 4096MB+ Linx?

    I was wondering how that was going to turn out. Very nice.

    This is as low as I could go for 4.0 with 25 passes of Linx and 8 hours of prime. I could probably drop the CPU PLL.

    The bug of BIOS occurred. It has changed into 4 though CAS # was set to 7.

    GFlops : to 52.

    Damn, Guys I envy you, with my D0 I need 1.44v to reach 4.44GHz !!!

    That makes temp of the CPU reach 79c with a room temp of 23c !

    That seems about normal. Mine needs just a tad less.

    Very nice indeed, about the best vcore I've seen for 4 GHz, what's load vcore? Cooling? Funny bug with CAS 4, I'm surprised it ran at all heh.

    Here's what I've managed so far on air on Windows 7 64, could perhaps drop vcore another notch or two if I was on water.

    Load - 4 GHz @ 1.112v / 1.21Vtt



    Finished

    What Do you mean?
    The test ran 1,5 hours.
