Hey guys im new to overclocking/unlocking cores in general. I recently built a computer with the Phenom x2 555 BE i figured that i might as well see if it is possible to unlock the cores and make it a quad. I am not sure what exactly to do. I turned ACC to auto and the computer hangs on start up at the windows screen. Is there anything else to do/try? Does this mean there cores are defective? Thank you for any help or guidance!

And EC Firmware to Hybrid but that depends on your BIOS. What motherboard?

You can try manually enabling / disabling the 3rd and 4th cores, or decreasing the per core % values to see if you can find stability. Maybe you could get to a three core... Very well could be "unlockable".

Mine needed a 0.025v increase on the cpu to boot.
Runs stable @3.7 quad with 0.075v increase.

Try increasing cpu voltage up to 1.5v max, try underclocking it (reduce the multiplier).
If it doesn't work try the same things with a triple if you have that option.
If that doesn't work you may have to accept that you got what you paid for a dual core, now clock the hell out of it. :D
