Quad XEON Processor shows up 8 processors - licencing 1

[hmckillop]

We have purchased a Quad Xeon Processor box with dual core etc etc.
for some reason in Windows 2000, it shows 8 processors, is this a fault in Windows OS (is it a mistake in hardware i.e. might we have 8 processors), and if its only 4 actual processors, but displaying 8 how many processor licences do I get?

Anyone seen anything similiar?

4 for SQL Server, 8 for Oracle I think:

The reason you are seeing the OS showing 8 procs instead of the 4 physical procs is because the procs are hyperthreaded. This is then represented by the OS as 2 procs instead of 1.

Thanks, thought it was an issue with Dual Core/Hyperthreading and OS problem.
So in summary, I buy 4 processors licences as thats all I physically have and then reap the benefits of hyperthreading.

How do things like isolating a single processor for an instance or database work, when in fact its only really half a processor? (do you have any experience of this?)

Cheers
