Have you overclocked it? If so, I suggest you go back to stock settings. If not, I'm just guessing that one or two of the cores that you unlocked work, but aren't stable.

Bad luck for you m8, one of your cores is defective, the best option for you is to go back to dual core mode. cause one of those unlocked cores is hanging up your system when it's being utilized.

I didn't overclock, it's on stock settings and i try to increase voltage for cpu to 1,5V and only thing i manage to increase is temp. over 60°C...
In bios i tested with "CPU Active Core Control" set cpu to 0,1 core to see if is one of those and bad luck my core0 is defective i'm unable to use it like x3...
So i'm did what yungster say back on x2...
I manage oced. cpu to 3.6GHz idle "40°C,, load 54°C" and memory to 900MHz 5.5.5.15 stabile ))
well it isn't quad but 3.6GHz*2 isn't that bad =)
Thanks anyway for replay...
