    Phenom II X4 for $99: Unlocking the X2 555 BE

    More cores, please!

    The other week saw several AMD chips released, and we found a couple to be very good overclockers and offer some great value for your money, particularly the Athon II X4 635. But there was one CPU noticeably absent from our tests: the Phenom II X2 555 Black Edition. Unfortunately, we were unable to test the chip at that time but we've got things ready to rock now and you're in for a real treat today.

    So let's get right to it. How does a full-featured Phenom II Quad Core CPU for $99 sound? AMD's new dual core hotrod, the X2 555 BE, is a special chip under the hood; in fact, it's actually an X4 and just needs a bit of help to unlock those two extra cores for all the performance goodness you can dream about at bargain prices. Does AMD want this to become widely known? We're not sure to be honest; on one hand, this could really spur a surge in sales but on the other hand it could poach their Phenom II X4 lineup. Either way, we successfully unlocked the X2 555 BE and we'll tell you how today and show the resulting performance increase.

    Not only that, but man did this chip overclock like a champ. 4.0GHz on air? Not a problem. Higher? Oh, now you're talking.

    The problem is they won't all unlock the 2 extra cores. If you do manage to unlock them you're in for a real treat, and if you manage to overclock that to 4ghz you have the best bang for $$$ ever I would say.

      Yep, for example I cant get my 955 BE past 3.5 stable on air. Anything more (or voltage) it gets unstable at some point... guess they were lucky. Anyway if yields are ok this should work for most of the cpus. Its just how far you are willing to get with the gamble To get x3 or even x2 and try unlocking. Its a lottery.

        And where the hell do you find a 555BE?

        I can't seem to locate one.

          I guess I must be lucky then, I got a 720 X3 that is fully unlocked and does 3.4 on stock voltage, 3.6 with a tad bump and if I really need to it will run at 3.8 - again all 4 cores.

          However, this hypothesis seems inconsistent with the lack of observational evidence to support it."

            My 720BE requires 1.5V for 3.4GHz and won't OC any higher. Haven't tried unlocking it, I already ordered a 965BE.
