Select Amd are unlockable

[dafunk_lull]

some select phenomII/AthlonII/Sempron tri/dual core amd processors
can reportedly have their disabled cores unlocked and put back in to operation.

athlon 64/phenom 1/sempronAm2 socket need not apply

To test weather or not your amd processor would unlock its disabled core

Advanced Core Calibration must be enabled either via the bios or Amd Over Drive utility.

its worth looking in to to expand the amd bang for buck

my current phenom II 720 hekka tri core is not able to unlock its forth core.


so if you bought a dual/tri core phenom II or athlon II or sempronII
give it a try

if successful and stability issues arise try to lower the ghz a bit to obtain stability.

also some will unlock but will not stay stable

its a crap shoot really it will either work or not

reports of some motherboards offering the Advanced core calibration feature but still having to obtain a bios update. gigabyte motherboards and asus motherboards seem better for unlocking due to both asus and gigabytes easy bios update techniques.. msi still says to copy the bios over to a Floppy disk..
