I am having issues "trying" to unlock the Phenom ii X2 550. After i set ACC to auto, enable unleashing mode, and set cpu v-core to 1.4, my computer still wont show a display. By that i mean when i start my computer, it will make all the beeps and what not but won't show a display on my monitor. After I wait a while my computer will finally show a display but during the start up phase, the computer will show "unleashing mode failed" and "CPU Overvoltage failed". Any help would be appreciated.
+1 ^ people are under the illusion that they can unlock disabled cores, the ONLY reason why some have done this is because as the FAB process gets better the quality of the cores gets better and to fill the market they disable good cores, in fact AMD is so affected by this they have removed the ACC option in the BIOS of their latest chipset to stop this happening, what ACC was there fore was to stabilize Overclocks on the Old Phenom Processes, mobo manufacturers are now using this as a way of shipping mobos, but as stated above buying and X2 hoping to make it an X4 is foolish as the disabled cores got be defective.
Try enabling just one of the two cores and see if that fixes it. If it doesn't, disable the enabled one and enable the other disabled core.
If after that it doesn't work, then both of your cores are bad and that is why they were disabled.
hw do i unlock one core at a time? i have the ma770t-ud3p motherboard with bios version f2c. its not like the asus boards where it ask to unlock to tri core or quad core.
is it something to do with my ACC value? if i set it to "per core" and then change the value for core 2 or 3 from default -2% to another value? i tried changing those values but i always come out with quad core.
When I looked into this before I did it (this was a while ago before I unlocked my 550BE) anyone that had real numbers suggested you have a much better chance of unlocking dual cores 80%+ than the 3 core ones 50-60%.
