Phenom II X2 555 BE unlock strange behavior

[gheorghe]

already done that (using AMD overdrive, not in BIOS)
CPU VID up to 1.4
NB up to 1.3 (or 1.28 hmm..?)
memory voltage up to 1.98-2

but still no change

Well you have a bad core. Seems like I remember someone else a while back having this very same problem when unlocking the cores on that CPU. Try it as a 3 core then.

I try to unlock it in 3 core but core 0 cannot be disabled and if I switch off core :

1 - win7 is not booting
2- it's recognized like phenom II X3 B55 but I still have the same problem
3- win7 is almost booting then BSOD

Bad luck...
