My phenom only has two cores!?

[spam38]

I'm not sure if this should go in the motherboard forum or the CPU forum.

I just got my brand new ASUN M3N-HD (nForce 750a) today along with a Phenom 9850. Its all running fairly well, except that the quad core processor only has two cores! Does anybody know what could cause this?

Here's a screenshot from CPU-Z

Try something other than CPU-Z?
Also why is you voltage so high (1.37), should be more like 1.20 - 1.30

Thanks for the reply!

I haven't even started tweaking yet, so the voltage is at whatever the default is.

Here are some more screenshots from AMD utilities:

As far as I know, I have the latest BIOS and drivers.

Did you install the AMD hotfix for what appears to be XP?

Well, I installed Vista and all of the cores showed up.

I'd still like to know why they aren't there in XP. I've installed SP3, the CPU drivers from both AMD's siteand Windows Update, and version 18.11 of the nForce drivers.
