Question for people with P4C processors and XP home only

[miri]

Do me a favor, go under device manager and tell me if XP Home lists 1 or 2 physical processors.

 

[ronnn]

mine lists two, very odd.

Hyperthreading. P4C's and other HT enabled P4 flavors can concurrently execute 2 process threads at a time and appear to the OS as 2 physical processors.

Yeah, so you SHOULD have 2. I didn't once, had to reinstall XP.

2 here. But I thought XP Home only supported 1.

Windows XP supports HT. Thus it knows the difference between 1 and 2 physical central processing units. Despite your task manager appearing to have two cpu's, it doesn't. They are "logical cpu's".

I have a dual Xeon and it appears that I have 4 CPU's! (WinXP Pro)

XP Home only supports 1 physical processor, Pro supports 2. XP is HT-aware, so it understands the difference between logical and physical CPU's.

Yeah, I picked up a couple magazines a month or two back that were rating OEM systems and they ripped them for using XP home because it did not support hyperthreading. Seems like they would do a little research before giving out misinformation. Unless you actually have two physical processors there is no need for XPpro unless you desire the other features(remote desktop,extra security, etc.).
