Dual-core support for Windows XP

Ok, I searched & didn't find it.

Can someone help me clarify this:

I thought the dual core systems were going to be ok with XP Home, since Microsoft said its only going to count packages. (IE: HT or dual core will be ok with XP Home - only count as 1 package)

And Pro would be good up to a dual-processor system with dual-core. (2 packages = 4 cpu's)

And what about the 840EE. Its only one package, so can it run on XP Home also, even though it supports 4 threads ? (1 package = 4 virtual CPU's)
 
Basically DC and HT don't count for the dual proc limit as far as I know. Only 2 seperate physical processors.

Q. How does this licensing policy affect products such as Microsoft Windows XP Professional?

A. Microsoft Windows XP Professional and Microsoft Windows XP Home are not affected by this policy as they are licensed per installation and not per processor. Windows XP Professional can support up to two processors regardless of the number of cores on the processor. Microsoft Windows XP Home supports one processor.

Ummm it does affect them as XP Pro only supports 2 processors, and XP Home only supports 1, so how MS defines a processor, as per core or per package does limit which OS you can use.

It mostly talked about server products, but the same... "only count per package" applies to XP Pro & Home.

So an 840EE will work with WinXP Home, as well as X2's, which is what I wanted to be sure of.

And you could use a dual processor, dual-core Opteron system with XP Pro still.

The first part is just reaffirming that how Microsoft classifies a processor (one dual-core processor is still one processor, not two), and that products licensed on a per CPU basis count each multicore processor as a single processor. So this was for products where you can simply add additional processors if\when you needed to scale up.

Customers asked for clarification because many other firms were changing per-processor licensing models into per-core licensing models.


XP doesn’t quite follow that model. A person can’t buy XP-Home and then later decide they want to add another processor, or 2, or 3. Likewise there isn’t a single processor version of XP-Pro, or get a 32 processor version.

I see what you’re saying, the concepts are similar, but, there is some difference there.
