SUCCESS UNLOCK AMD PHENOM II 550BE CORES :
WHY AMD lock / hide Phenom II 550BE / 720BE cores
The current Phenom II architecture is very unique v.s. Intel’s Core2Duo and Core2Quad series. Unlike the Core2Quad, where by 2x Core2 Duo’s bridged together meanwhile AMD’s Phenom II is a chip with four individual cores. AMD chip fabrication manufacturing processes i the same. There are parts which not meet the quality control. for Phenom II Quad cores, some may have defective cores or cache. Instead of dispose these defective Quad cores , AMD decided to repackage these chips as Dual cores (Phenom II x2) or Tri core processors (Phenom II x3) . It was a win-win for AMD & consumer. They could sell these processors at a lower price to recover costs and also minimize wasted . Thats why AMD lock or hide Phenom 550BE &720BE cores.
When the Phenom II 550BE & 720BE was launched, it was popular among mainstream enthusiasts. because all BE processors come with unlocked multiplier, which enable overclocking AMD 550BE / AMD 720BE extremely easy. Furthermore, it was much worth to buy against Intel’s Core2Duo E6xxx series, but performance actually outperform the E8xxx series.Will you pay Intel for a Dual core when you can get a quad core from AMD at the same price?
However, the surge in demand for 720BE processors started when a Korean overclocker discovered the way to unlock “locked / defective” cores . He used a motherboard with a SB750 southbridge which supported Advanced Clock Calibration (ACC). Very soon afther that, Biostar & AsRock mobo reported similar success in unlocking both 550BE & 720BE. Later unlocking news include AMD Phenom X3 710 and X2 545BE processors too.
AMD reported record increment in sales of AMD Phenom II processors, no doubt, in part due to fourth core unlocking. Many believe that the increasing rates of successful unlocks is due to AMD purposedly binning perfectly working X4s as X3s to fulfill market demands. This mean your chances of getting an unlockable AMD Phenom II 50BE / 720BE chip just got better.
