Core I7 860 running 4 cores / 4 threads instead of 4/8

Hello, I have I i7 860 paired up with a Biostar TP55 mobo. When I run CPU-Z it says I have 4 cores and only 4 threads, when I know it should be 8. I've already updated my bios. Any other ideas?

Thank you

    Two first things to check

    what is the BIOS setting when it comes to enabled cores and hyperthreading?

    Using msconfig, navigate to Boot > Advanced Settings and make sure Number of Processores is unchecked.
  2. Thanks for the msconfig part, I didn't know about it. Is it for Vista 64bit also?
