I have been able to unlock all 6 cores on my processor in the past and all 6 cores have been running well for the past 4 years. A couple of days ago I had to reset the bios, and when I tried to unlock the cpu this time it didn't work. In the bios all 6 cores show up, but when I go into cpuz it says I only have 4 cores.
