windows xp home edition and amd x2 support

[sonoma1993]

Does windows xp home edition sp2 have support for the amd athlon 64 x2 cpu? If so how do you enable the dual core support? Is there a patch you have to download? I want to get a dual core chip. im thinking of getting the x2 3800

IIRC XP home supports only 1 CPU.

Home does support multicore processors.

This thread is still on the first page

I know Home supports dual core processors, but I wonder how they distinguish between a dual core CPU and a 2 CPU system. Obviously Home has support for dual CPU systems, it's just that Microsoft wants you to buy XP Pro if you have a Dual CPU system .

The motherboard BIOS has to be upgraded to support Multicore.

Multi Core processors are considered as One CPU by Windows. Thus it s is supported by both WinXP Pro and WinXP Home.

MultiCore is not like Dual CPU, are you sure that CPUZ was updated to recognize Dual Core?

Dual core is recognized by windows as 2 physical cpu's it just that Microsoft decided not to charge more for a dual core systems.

So let Focus.

"Dual core is recognized by windows as 2 physical cpu's".

So it should Not work with WinXP Home???? :shocked:

Since it recognized as two CPUs the current version of CPUZ would recognize it as two CPUS????? :shocked:

Edit: According to this Post CPUZ doe recognize MultiCore as two CPUs.

Let's be clear, whether you have dual core or dual cpu's you have 2 physical cpu's. It doesn't matter how cpu-z reads it, this has to do with windows.


Windows XP home edition supports 2 physical cpu's and 2 virtual cpu's and Windows XP professional supports 2 physical cpu's and 4 virtual cpu's.

Let's be clear, whether you know the answer or not, you post the wrong one. I really have no idea where you came up with Home supporting 2 physical CPUs.

Please read this

http://www.microsoft.com/licensing/highlights/multicore.mspx

please note this took less than 30 seconds of searching to find. I'm going to quote a couple lines, as I know most of you will just not read the link.

On October 19, 2004, Microsoft announced that its server software that is currently licensed on a per-processor model will continue to be licensed on a per-processor, and not on a per-core, model.

Ok that is for server software, not for desktops.

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.

Let's be clear, whether you know the answer or not, you post the wrong one. I really have no idea where you came up with Home supporting 2 physical CPUs.

Windows XP Home Edition:

1 cpu
1 cpu with hyperthreading
1 cpu with two cores


Windows XP Professional:

2 cpu's
2 cpu's with hyperthreading
2 cpu's with two cores each


PS: I think of the cores as being real physical cpu's instead of virtual cpu's like hyperthreading.

Sorry for the confusion.

Well that link is just wrong, it says the 9x family supports multi-proc. That is false.

 

[bsobel]

Windows XP Home Edition:

1 cpu
1 cpu with hyperthreading
1 cpu with two cores

Windows XP Professional:

2 cpu's
2 cpu's with hyperthreading
2 cpu's with two cores each

Need one additional clarificaitons. XP can support CPU's with more than 2 cores. You just won't see them anytime soon

Not only that the MultiCore is Not like Dual Physical CPU, there is even a difference in the architecture between the way Intel goes about the two cores interaction and the way AMD designed the interaction (mainly around the way the Cores exchange information with the outside RAM).
