XP on Dual Quad Core Xeon

[Guest Daniel Jameson]

Hi,

 

Does anyone know definitively whether Windows XP will run on dual quad core

Xeon hardware and use all 8 cores?

XP doesn't care about cores/socket, only sockets. XP Pro will use

both, Home will use only one.

If what you mean is that XP will only see 1 core

per physical socket, that is incorrect.

 

I am running 2 dual-core Xeons on an ASUS

PC-DL and Task Manager shows 4 CPU Usage

graphs. XP "thinks" it has 4 logical processors.

 

As far as "using" all your cores, the OS will, but

very few applications know how to do this (some

imaging software, some video transcoding software)

and will continue to poke along using only 1 core.

 

But multi-cores will allow you to run lots of apps

simultaneously at full speed and will offload OS chores to other

cores.

Hi,

 

Yeah, video transcoding is exactly what we want to do with this thing, and

we are going to double check with the app publisher to make sure it will

take advantage of 8 cores.

 

Thank you.

Dan.

Windows XP Pro will

 

Windows XP Home won't.
