It will recognize it but XP doesnt use all your cores like it should unless you get the hotfix. It's somewhere in this forum in a sticky thread saying "dual core patch.."

It can utilize up to 2 cores however with a quad core I dont think it will utilize it properly. Im not 100% on that though.

I don't think so, If i remember right it was originally only licensed for single core, but after dulies came out they bumped it up. I don't think it has been bumped up to quad yet.

Windows XP Home will recognise any quad core CPU. This is down to the fact that it is lisenced to support up to one physical CPU. It doesn't matter how many processing cores the CPU has, so long as the motherboard only has one CPU socket. Any application that makes use of multiple CPU cores that you try to run on Windows XP Home will operate perfectly fine.

It would be a good read.

Thanks.

Not much of a read, but the facts are available at Microsoft's homepage.

When it comes to multiple processor cores, the software has to take advantage of it. Although the background processes of Windows XP installations aren't multiple threaded, this doesn't affect any actual programs that a user intends to run on such an operateing system. To be brutally honest, I'm unsure of many multi-threaded applications that a typical home user would make use of, bar video editing and encodeing tools. Though both XP Home and Professional are perfectly capable of manageing the resources of multiple processing cores.

He is correct. The same with Vista. You need Vista Business or Ultimate to run multi-processors as in more than one socket.
