Win 2003 identifies 2 CPUs in ML 330 - really only 1 CPU

I've just gotten two new ML 330 servers from HP. One with SCSI RAID, the other with IDE RAID. I purchased the Windows 2003 standard CD for HP Prolaint servers from HP and used this to intall my servers along with Smart Start. After working on them for a day, I'm finding that Windows 2003 thinks that there are 2 CPUs in each system. I popped the cover just to double-check and there is only 1 CPU in each. What the heck is happening? Anybody know?

Dave:

What you are seeing is the effect of Hyper-Threading. This is normal.

Each CPU emulates two logical CPU's to the O/S.
