Hi;

Had the same exact problem with my FX-6100 (6 core) only 4 were showing up on everything UNTIL I remembered that I had previously set the cores to 4 in MS config (was running a Phenom II 965BE 4 core).

Bring up the Windows Start menu, in the Search box type MSConfig and press enter.
The System Configuration dialog will come up. Go to the Boot tab and select Advanced Options, at the upper left corner either uncheck the number of cores of re-set them to 8. Select Apply and reboot. All 8 cores should now be available.

Cheers;
Doc
