i have had a x2 555 combo from micro centre with a MSI 785GM-P45 AM3 785G mATX m/b a few weeks
decided to try unlocking the cores
try a few setting but when i reboot i get nothing will not start up or not even to welcome screen from msi and got to reset cmos with jumpers to get back into bios.
ok if i cannot unlock them fair doos but i read the x2 555 is a x4 cores with 2 cores disabled ???
now when i go into bios
and put cpu core control to manual; to see if i can disable core4 and try that way, but i only can see 2 cores as in the pic here



why cannot i see all 4 cores so i can disable them manually tried it on auto manual and still only see 2 cores and why carnt i up the voltage as all the cpu voltage are grayed out for some reason , am i doing something wrong ?????

any help would be appreciated or as anyone used this board to unlock the cores .

Its a Baddun mate, your not really doing anything wrong there, not all Phenom II x2s are working Quads, some of them are simply broken quads. In this case enabling buggered cores is gonna mess up your Startup so its not gonna boot.

Do a little more research into unlocking on your mobo, read some reveiws and grab the batch number from your Processor and compare it to others that can or cant be unlocked.

Try unlocking them one at a time, might get a working triple core.

My 555, set ACC to AUTO, needed +0.025v CPU voltage before it booted, stable @3.6 quad.
