@malmental I can unlock, i have tried a few times however, it won't post with 4 unlocked but with 3 it will. Then it crashes when loading windows everytime with 3 cores. Any suggestions?
It also depends which cores you unlock, if you have the option of selecting which ones to unlock. My 555 will run with 3 but i have to select the correct cores to unlock manually. I just did it to see what it could do i run it everyday with 2 cores.
I had to bump the voltage a bit to get it stable on the third core but nothing much.
