I recently upgraded my server downstairs from a E8400 to a Q6700.

However, when I go into task manager and every other tool, the computer swears that there are only 2 cores on the machine. In addition to that, the computer runs FREAKING slow.

Does anyone have any ideas? I'm at a total loss...

You could need to do some BIOS upgrade. Have a look at the BIOS changelog. Which board? – Jens Erat Nov 1 '11 at 17:06
EVGA nForce 780i SLI FTW motherboard – David Nov 1 '11 at 17:09
Run a Linux Live CD and you will see if the additional cores are generally visible. – Robert Nov 1 '11 at 17:10
Good idea - didn't think of that! I will when I get home tonight – David Nov 1 '11 at 17:16
` the computer runs FREAKING slow` <-- Sounds more like a disk issue than a CPU issue. An E8400 is pretty damn fast. – Billy ONeal Nov 1 '11 at 17:16

Do a BIOS upgrade. The changelog for the latest version includes this:

Improve CPU compatiblity

This will probably solve your issues.

I just RDP'd in and CPU-Z reports the BIOS are on a VERY old version. Great idea, I'll try when I get home! – David Nov 1 '11 at 17:19
After updating the BIOS, the problem remains.. – David Nov 4 '11 at 12:49
Didn't get at first it was a downgrade... Can you switch the CPUs between your both computers (so test the Q6700 in your gaming rig)? What's CPU-Z telling about the Q6700? – Jens Erat Nov 4 '11 at 14:30
After a BIOS flash and a reset I have all the cores! Thanks a lot! Computer is still slow and buggy though O_o – David Nov 7 '11 at 13:49
