Just wanna share some infos bout this topic. Phenom X2 555 BE die shot shown below...



Now take a look at a Phenom II X4 die shot below. See the difference? You're essentially looking at 555 BE but despite the X2 moniker, it's a quad except it's simply handcuffed (for the moment). So the X2 555 BE is really just a Phenom II X4, but with 2 cores disabled. As we can see in the die shot, 4 cores are present. A Deneb with 2 cores disabled is codenamed Callisto, but it can easily be unlocked, as we'll see. It features all the L3 cache of Deneb, and has all cores present, it's just that two are disabled.

Ok, so now the big question: How to unlock those two extra cores of juicy computing power? Well, as much as we'd like to say it's a deep secret in the dark arts, it's not. In fact, it is a rather simple thing to do. The key is your motherboard; you must have one that has Advanced Clock Calibration (ACC) available in the BIOS. We went into BIOS and enabled ACC, and set it to “Unleashing Mode”, as it is titled on our ASUS Crosshair III Formula testing board. Reboot. The result? An unlocked quad for $99. Unleashing, indeed. Can you say "Booyah"?

When unlocked, the name of the chip changed from Phenom II X2 555 to Phenom II X4 B55. Interesting. Now, beyond the ACC requirement, there is one other caveat that needs mentioning here briefly. In the $100 price range, an unlockable Deneb is likely, especially with these newer chips, but you have to run the luck gauntlet; you may be able to unlock the chip, you may not. There is no guarantee, but if you're a betting person, we say go for it.

how come your speed is 800mhz only ? maybe there's something wrong.

[devilsburger]

^^ CNQ was enabled in the bios brad that is why you can only see 800mhz and the Vcore was also 1.000 instead of 1.360 or so..I did that on purpose kay para save daw na sa kuryente..hehehe..
