Greetings, I am having problem unlocking this CPU.I was using it on a Gigabyte board with unlocked third core(fourth is unstable in Windows but it POSTs with it).Now when I put it in a MSI board with same chipset.I went with standard procedure of turning on "CPU Unlock","Core Unlock" and Advanced Clock Calibration.Upon applying settings,PC would not post and I had to take take out battery. Upon another try,I tried to unlock just the third core by setting "Core Unlock" to manual as I did on Gigabyte board.But there were only two cores listed instead(on Gigabyte board,there are four). What am I doing wrong?
