Flip a switch on the motherboard, enable the feature in the BIOS, and you now have the capability of unlocking disabled cores.Īctivate Core Unlocking by turning off the rig, flipping the Core Unlocker switch (located on the upper forward corner of the motherboard, it is the uppermost switch) and turning on the system. (unlike most, I will not criticize AMD for that…they disabled the cores for a reason)Īsus has replaced ACC core unlocking with a new Hybrid feature called Core Unlocker.

This capability was removed from the 800 series chipsets, much to the chagrin of those that had been aware of the capability. I guess I really didn’t pay attention, though I had a few 700 series boards but no processor that required unlocking. This capability wasn’t advertised, but I don’t suppose you could call it a “well kept secret”. The “Zosma” line of Phenom II X4s are actually Thuban X6s with two cores disabled.Ĭore unlocking was actually accomplished on earlier AMD chipsets with 700 series Southbridge which had ACC, or Advanced Core Calibration.

The Phenom II X3 line is entirely made up of X4 CPUs with one core disabled, the Phenom II X2 line has two cores disabled. One of the possible “disabled features” is the disabling of one or more cores on their multi-core processors.
