    Q743A seems to be leading the pack (4.3GHz 24/7 stable at 1.344vcore). But that is just my result

Maybe the higher FSB needs more vcore for the CPU to be stable? Any thoughts? See below.

    My CPU
    Week: Q748
    Batch: A219
    Spec: SLAPL "C0"
    Packaged: 1/29/08
    CPU = 8x500 (4GHz)
    vcore bios: 1.42
    vcore CPUz: 1.392
    vcore orthos: 1.38
    default vcore: 1.13

    Friend's CPU
    Week: Q745
    Batch: A553
    Spec: SLAPL "C0"
    Packaged: ?
    CPU = 9x444 (4GHz)
    vcore bios: 1.35
    vcore CPUz: 1.33
    vcore orthos: 1.32
    default vcore: 1.18

    You're correct, it takes more voltage to get 8x500 stable than 9x444.

    The 743 and 745&46 seem to do very well. I have a 745 myself S spec SLAPL that can do 4300 at 1.36v 4500 at 1.45v and can bench at 4800, max is 4900 on water.

    They seem to be doing very well Q743A here. 4.3G @ 1.36v/ 4.4G @ 1.392v with a TRUE. Ran 1 hour of Orhos, which is stable enough for me. The others I've seen have done well also.

    It idles at 28C and loaded irrc at 55C for 1.36v and 60C for 1.392v. That was the cpu temp. The cores loaded irrc at 65C and 70C, but then they idle at 50C. So who knows how accurate they are.

    Time to quit before I have to call the fire department and put them on stand-by.
    Look what you crazy guys at XS have made me do now.

    SuperPI 1M=10.328s


    I've hit the practical wall with these parts on air but I'm not too ashamed of my daily driver.

    do you fiddle your fingers while your palms are sweating, waiting to see if it will boot all the way into windows, praying for it not to BSOD... also while you have on your mind "I'm better off not checking my temps"? I do.

    nice results

    I try to boot at 2000fsb and it bsod's... anyone have experience with this... once I set volts way high like 1.52 and it made it to windows and then shortly after BSOD... is that the overclock or something else. I'm running Vista 64 by the way.

    On the box itself, the series of number after FPO/Batch# is your Batch#. On the CPU, this same series of number will also show as the very last one on the IHS.
