Phenom II X4 945 showing as a Dual Core, Bios show ACC is on auto and all cores enabled

My friend just got his phenom II x4 945 today to replace a athlon II x2 240, well first boot went to a dual core, so i went in the bios set acc to manual and Cores 2 and 3 to enabled. Boot up again still shows as a dual core. Task manager, Cpu-z show as a dual core and device manager shows all four cores.

After that attempt i reset the bios to optimized defaults and still no change, Is this a glitch? or something that has to be changed within Windows 7?
