HI Runn3R.
My X2 BE 550 is a dual-core processor, but I managed with the help of GA-MA790X-UD3P to unlock two more cores. Now I have a processor with four cores X4 B50 (core 0,1,2,3). The core number 1 can not OC more than 3.3 GHz, it becomes unstable. I'd like to lock core 1 and then I had powerful X3 processor that could OC to 3.8-4 GHz. Thanks for the help.
