Dual-core Xeons on the Paxville core support Hyper-Threading, so each processor is viewed by the OS as two physical and four logical units.
That is, a dual-processor system based on Paxville CPUs can work with eight execution threads simultaneously.
We’d like to note that even Windows XP Professional SP2, not to mention newer products from Microsoft, works without any limitations on a dual-processor system with two dual-core Xeons, despite such a big number of CPU-like units. Below is the formal specification of the Paxville-core Xeon:

The latest version of CPU-Z already knows the Paxville and reports the following about the dual-core Xeon:
