AMD Phenom II X2 560 OC

I'm looking to oc my Phenom II X2 560, which has been unlocked to a quad core. It is completely stable, I have run it through Prime95 for 16 hours. I have an old Athlon 64 X2 6000+ heatsink I'm using on it that keeps it at a cool 34C idle, and 45C under load. I'm hoping to reach a stable 4GHz. My case is well ventilated too. However I don't know if I'm missing something or if my board, an Asus M4A785-M, can't handle it. I have tried different combos of multipliers, voltages, and reference clocks.

    you may have a core that is unstable at a certain voltage, multiplier, etc., probably why it was locked.

    as is your quad is plenty fast for gaming and single gpu video card.
  2. I can get it to 3.5GHz at 205x17.5 at 1.385V. But no farther, but I see your point. Thanks.

  4. my Phenom X II 560BE unlocked to Phenom X 4 B60 quad core.
    on 3.4Ghz run Prime stable for 22 hours. voltage was 1.340 +-
    Mb- Asus M4A89GTD PRO/USB3
    Cooler - CM 212
    Case - CM 690 II Plus
    PSU - Tagan BZ900


    testing it now on 3.9Ghz as Quad Core
    1.4280v with EPU profile on high. havent changed anything but the voltage so far. it seems stable if i run only prime95, temp is 49c at 100% load.
    writing this comment while prime working. tried 4ghz but got voltage jumps and a blue screen while prime run and i was trying to open more applications, it seems some default bios settings are allowing more voltage than what i allowed this causes instablitiy since its already on 100%.
    at 3904 Mhz it seems to be stable on all four cores. no V-drops or jumps.
    229mhz x17 seems stable.

    with Asus auto tunning it managed to run as Triple Core at 4.3 Ghz
    under 1.4V. might be a better combination for running games. though whats interesting is how far and stable it can go as Quad Core. so far it seems as a very decent chip.
