    [AMD] Unlock deactivated cores on Biostar Motherboards

    Hey,

    yesterday I got a new Biostar motherboard (TA790GX A3+) and I found some modified Bios for it. I flashed it and after flashing it was possible to reactivate 2 cores on my A2 550. I also tried with my old CPU X3 720 Black Edition and it was also no problem to reactivate it.
    They guy how modified it made a new version for almost every 790 motherboard of Biostar.

    Here you can download the BIOS version:

    TA790GX_A3(R1) link:w*w.4shared.com/file/117996965/ec068ea0/TA790GX_A3__R1_.html
    TA790GXBE(R1) link:w*w.4shared.com/file/117997038/58ad5ab2/TA790GXBE_R1_.html
    TA790GXE(R1) link:w*w.4shared.com/file/117997195/dd31a4b2/TA790GXE__R1_.html
    TA790GXE_128M(R1) link:w*w.4shared.com/file/117997123/d7a6d84c/TA790GXE_128M__R1_.html

    You need the following settings to unlock the cores:

    HT link @ 1.6GHz
    ACC @ all cores
    Value(all cores) @ -2%

    The forum where i find it was: w*w.xtremesystems.org/forums/showthread.php?p=3905610#post3905610

    Please tell me your experience with unlocking the cores.

    PS: If you try this always update your BIOS in Windows. The F12 function while booting won't work.
    If you want I can upload some screenshots.

    do you know if the x3 720 will usually unlock the extra core?

    was thinking of getting it and unlocking (or i could have your old one )

    Re: [AMD] Unlock deactivated cores on Biostar Motherboards

    The deactivated cores are not always going to unlock, some will be defective, hence why they were binned for the X3 line. Of course if demand for the X3 processors outstrips the naturally defective core-chips, then you will get some quality X4s that have one disabled by default.

    Either way, I'd buy an X3 if you're happy with the idea of having 3 cores... finding one that unlocks is just a bonus.

    If you're intentionally looking at an x3 to have a quad- just go buy an x4, that will save you some disappointment.

    booting into bios is not a problem. The cores may still be defective. First try and get into windows and run prime on each core for an hour........

    The unlock works on lots of mobos with SB710 and SB750.

    I would update your signature too. Glad to hear that you unlocked the X3 720 too.Are you using the stock cooler??
