Phenom II 965 with 2 cores in vista?

Greetings to you all.

I have a problem with a CPU upgrade. Former Cpu was Athlon x2 6400+

I got the Msi K9A2 platinum motherboard and the new cpu is the Phenom II x4 965 with the revision C3.

I got the latest BIOS 1.9 and it is all well in the BIOS as it should be, but in windows vista basic 64 bit I only got 2 cores and cpu-z also show 2 cores.

Have anyone a clue what the problem could be?

msconfig > boot > advanced options
Uncheck "Number of processors" if it's checked off.
Reboot.

Yes the cores are still on and running. The OS just pretends they aren't there and wont use them. Never tried it myself, but AOD should still see them since it polls the bios not the OS iirc.

You're welcome. Vista still had it set as if it was a dual core.
