Hi, i have a gigabyte ga-880gm-ud2h rev1.4 motherboard and bios version f8 and amd phenom IIx2 555 processor with 4gb Ram and ati Hd 5770 graphic card. please help me to unlock the cores. i tried by setting the Firmware to hybrid and ACC to auto but did not succeed. would you please suggest me how to unlock the cores.
It would appear that your chip is unfortunately one of those that had defective cores, and this is why it was locked to a dualcore
these are the breaks I'm afraid,
it may be that a little extra voltage might help stabilise cores, but if you aren't even getting them to show up, I wouldn't try it.
try this setting :
