windows xp on dual core cpu

Dollar · 09-19-2007, 06:16 AM

Somehow I have come across a thread saying that windows xp home will not work properly on a dual core processor as it only supports a single core processor. Is that really true?

XP home is fine, it will work with a dual core. Its Dual processors that XP home doesnt support.

When there are perfomance losses seen when teh dual core models were first introduced one article used for problems seen running XP on dual cpu boards was an effective edit of the system registry offered for the single dual core boards as well. Since then AMD and Intel alike have released their own patches. AMD saw the majority of problems at first. http://support.microsoft.com/?id=896256

not ture as all the way from windows nt4 windows have been disinged to run with more then1
processor xp can have up to 32 all the duel core is 2 processor bulit in one the only think you might have to do is update the chipset drivers

The registry edit seen in the article there originally referring to performance losses seen when running multiple cpu boards was later applied to problems with boards seeing only one dual core processor. One update for XP originally intended for multi cpued board applies to dual core models as well.

Update for Windows XP (KB896256)

Brief Description

Install this update to fix a situation where your Windows-based system that supports processor power management features, and is equipped with multiple processors, may experience decreased performance.

AMD has their own dual core optimizer available for download at http://www.amd.com/us-en/Processors/..._13118,00.html

The first link is for XP pro, XP home does not support Dual Processors
Scalable processor support – up to two-way multi-processor support. XP home (no)
http://www.microsoft.com/windowsxp/h...choosing2.mspx

The second link is a AMD driver for the AMD dual core processor to help in (some) games.

XP Pro is still XP. Dollar's question was running XP with a dual core cpu installed. Multi cpued boards have generally been seen only in server systems until the more recent FX-74 model boards came out for seeing 2 dual core cpus instead of one single quad core until AMD finally comes out with their versions of quads.

The second link is for the dual core optimizer since some games were seeing problems running on dual cores by AMD. On the new build here XP Home has experienced some interesting problems between video and sound while Vista runs like a charm with the AMD AM2 6000+ X2 dual core cpu in use. The Asus board does have the latest bios and drivers available ruling that out.

XP Pro on the other hand is more network orientated for business application with that version. But the MS article can easily apply to either version due to problems seen originally when adding SP2 into the mix on older installations. That would be for XP orig. and SP1 installations when seeing the second service pack go on.

If you buy XP now just about every disk already has SP2 included at this time. But that was the main reason for problems seen with XP when the dual core models first arrived.

Thats not true. Windows XP can only support up to two processors.

Even XP Pro has it's own limitations since it offers more networking feature while not being a dedicated server type version to begin with. In fact the dual core cpu has done well in both XP and Vista for the new build here while video and sound drivers have been more of a cause for concern. Even the XP updates for other hardwares seem to be more Vista orientated while the cpu has been doing what it should.

Not true at all. I built a server for my work consisting of four (4) xeon quad-core cpus and it was originally running windows xp business but then later was switched out with linux. All 16 cores where recognized and utilized.
