Intel 840 EE: OS limitations on number of processors

[areiel]

Greetings all,

I will shortly be building a new PC using an intel 840 EE CPU. My understanding is that this is seen logically as 4 CPU's: 2 from the dual core and 2 per core from hyper-threding.

I vaguely recall that certain versions of Windows XP will only run on a maximum number of processors. Can someone please advise as to what the limitations are?

Thanks,

Areiel

I think XP Home might have a problem but am not sure on that one, XP Prof will be able to utilize it fine i should imagine

XP Pro can handle 4 threads at one time, home can only deal with two.

Niether should have a problem. Microdsoft Licenses Home for a single Proc and Pro for dual Procs. Microsoft has stated that it doesn't make a difference how many logical or electrical threads a single or sual proc can handle. That said use pro because even if it is support you don't know what the actual shortcuts MS used on home for single CPU support.

Either XP Home or XP Pro will run a Pentium Extreme Edition 840 at full capability, so if that is what you are worried about, then either will suit your needs. I prefer Win XP Pro as I enjoy the extra networking features it supports.

What you are thinking of it not Logical CPUs of even Dual cores, but multiple SOCKETS. Home is only licensed for one physical Socket, it can have as many cores on that one sockets as it can take.

^ - and that, my friends, is your final answer. :thumbsup:

However, if you will be using a home network, I would still prefer XP Professional due to the un-"neutered" file sharing and security features.

That poster made a few typos, but even considering those, his post was still much easier to understand than the post two posts above it.
