Hyperthreading Technology

[Guest]

I read this article the other day from PCWorld Mag dated 2002 (forgot month).
Anyway the articl stated that HT Technology is not supported in Windows XP
Home edition. Is this still true?

I scanned the MSKB for that and all articles about HT that I found,
apply to Home Edition as well. So I doubt that PCWorld is correct
here.

What they said (I'm sure) was that XP Home does not support
multiple processors and you have confused that with
hyperthrerading.

It never was true. XP Home has always supported hyper-threading. See

You are misunderstanding the article. Windows XP HE does not support more
than one processor. It does support HyperThreading, although you may want
to disable it. Hyperthreading only has benefit for those programs that are
written to take advantage of it, and the majority of the stuff out there is
not written to take advantage of hyperthreading. You may wish to conduct a
test...go a few days with H/T on and then a few days with H/T off and see
which is faster.

Bobby,

I just got a Dell XPS Pentium 4 3.8GHz with HT - I assume this is
Hyperthreading Technology. It also has Windows XP Home SP2 - they seem to
work well together<G>

Are you saying it may be faster with H/T disabled?
If so, how do I do that?
Any down side to disabling HT?

Thanks,

Bill

Hello, Your BIOS should have the HT settings. Have WindowsXP Home, tried
running with and without HT. Found when video editing seems to be a little
bit faster with HT enabled other wise I cannot tell the difference. Unit ran
fine either way.
Take Care.

beamish,
I found the setting.
Tried "with" and "without" - I agree with you - can't tell the difference.
I went with "with".
