After you use the unlocker option. You need to go and select the core in the bios.

If your unlocking extra cores on the CPU, you should also be giving the CPU a extra notch on the V-Core as they are disabled for a reason.... unstability

Mhmm, MSI 880GMA-E45...

I can't recommend unlocking on this board. Unlocking will turn your 80W dual core into a 125W monster - which will easily overload the weak 3+1 phase VRM on this MSI board (Low-end MSI boards are known for CATASTROPHIC VRM failures). The board is not even officially rated for anything above 95W either.

For your own safety I recommend you don't unlock. Don't know what I'm talking about? See "About VRMs & MOSFETs" in my sig

X3 would be ok but not X4. That is suicide even at stock clocks.

Instead of selecting auto, you may want to manually enable 3 cores at most.
