Hi all,
i haven't found anything on this using the search function.
From what i heard Microsoft licenses Windows XP based on sockets not cores,
however i was hard pressed to find information on this on the MS website.
Does Windows XP support all available CPUs (and virtual CPUs) available from
a Dual Dual Core Xeon with HT system?
While featuring only two sockets this system should show eight CPUs in the
taskmanager.
Thanks in advance for any info on this

Cheers
Björn

My understanding is that XP only supports two CPU's. Thus even the
dual core HT processor is a waste, let alone Xeon's.

Older dual Xeons show as 4 logical processors under Pro, and
it uses them all.

Running ASUS PC-DL - dual 2.8 Xeons.

A Pentium EE with Dual Core and HT (4 CPUs in Taskmanager but only one
socket) works fine with XP and so does a Dual Xeon with HT system.
The problem is, what counts as a CPU for XP?

It's no problem, a CPU is a socket as XP counts it..
So in XPhome, you can have one Pentium EE (2 cores, both HT enabled, = "4"
CPUs) and as it's on one socket...
For XPpro, double the numbers..

I was trying to look up the page I got it from but Microsoft's site is
as usual all but impossible to find anything on.
