SUCCESS UNLOCK AMD PHENOM II 550BE CORES : step by step guide

Unlocking your “LOCKED / defective” AMD PhenomII cores, the UNLOCK AMD PHENOM II 550BE

process is very simple & straight forward.

1. Restart & press ‘del’  key ,go to BIOS setting.
2. Set ACC (Automatic Clock Calibration) to AUTO.

* Asus and Gigabyte Mobo : Pls Enable “Unleashing” or set  “EC Firmware” mode to “Hybrid”
3. Reboot.

If unlock AMD 550BE successful, your processor should have designation starting with X4 when you reboot. Congratulations, because you have just successfully unlocked your AMD Phenom 550BE hidden cores for FREE.

After success restart , you can press ctrl+alt + del key then launch Windows Task Manager , go to Performance tab ,you should see 4 column which representing 4 cores of your AMD Phenom II 550BE . you can download cpu-z & should see your AMD Phenom x2 550BE already change to AMD Phenom II x4 code name Deneb, specification AMD Phenom II x4 B50 processor cores & threads increase from 2 to 4 now.

Unfortunately, if you only able to see 3 cores via CPU-Z  mean your fourth core is defective. then you could try unlock again using other brand mother board. For 550BE owner, you were still able to unlock one of the two locked / defective cores

Once you are in Windows, or any other OS that you use, you should begin stability testing for your unlocked processor.

I would recommend Prime95 “Blend Test” for 12-24 hours to ensure stability especially if you intend to overclocking AMD Phenom 550BE after unlocking.
