Bit of luck you can unlock that 4th core as well as clocking it dude, Worked for me on my 435, now its a phenom x4 B35 running at 3.2Ghz smooth as you like
Good luck and enjoy the build
I have a few questions about the unlock...Will it void my warranty? Where can you learn how to do this? It would be greatly appreciated because I have never heard of this concept of 'unlocking' before.
