Got the parts yesterday and tried to unlock it. With new bios I was able to unlock the processor to X4 B50 but it was very unstable, locking almost instantly after completing Windows boot. Tried increasing Vcore to 1,4V and also raised voltage on NB, lowered NB clock, CPU clock (2,4GHz) but nothing. Going to send it to my father as he needs it quite desperately. Did a mild OC to 3,5GHz X2 with 1,325V and undervolted P0 to 1,8GHz with 1,075V (did not get CnQ to work so I did it myself with K10Stat).

Any hints on how to make it stable (once I get my hands on it again), NB voltage, CPU voltage, CnQ disabled? I know he'll be satisfied with the performance he's getting but I was hoping for even more (of course).
