Number of Cores 2? WTF?

Ok the box the mother board came in says:
AMD 760G Chipset
AMD phenom II X6

It also says something about core unlocker? I thought it was a quad core and in task manager it shows 4 cores. However here it says 2? Also on the boot screen it says press 4 to unlock cores.

This is the board:
