New CPU, new OS?

Logla · Mar 1, 2004, 03:18 PM

I'm going to be getting a new CPU in a few weeks time. I have at the moment a P4 2.4b w/533FSB. I'm going to upgrade to either a 2.8 or 3.0c w/800FSB.
Will I need to re-install the OS as a multiprocessor ACPI PC instead of uniprocessor as it is at the moment? I ask because the new machine will have HyperThreading whereas my current CPU doesn't.

I don't think so . . . you can always just install the CPU, and see if Windows sees 2, and reformat if it doesn't.

might make life easier if I dont have to re-install XP. I just got the base build tweaked the way I like and I dont want to have to go through that again.

I have a question.

Does XP Home support Hyperthreading?

Thanks I was just wondering and had a brain-fart about since how Hyperthreading works similar to dual processor setup I wondered if it worked with Home.

Hmm I wonder if that means it could support dual processors?

PangingJr · Mar 1, 2004, 10:46 PM

Hmm i dodnt think XP HE takes dual processors..
but i see the intel's page as it's on HT as well..

i think the extensions are autmatically turned on using the default cpu driver supplied..... it that the programs have to know were to look... ???

once you have the OS that supported it, enable the HT in the bios and it should auto detects.

and Logla, the new CPU will have 2 'internal' processors but it's still single CPU,
so i dont think you'll have to reinstall windows.

i like to confirm this to you.. since my last reply to you seem did not...

the XP HE does not support two processors machines,
you can install the XP HE on one of the multi-processors machine but it'll only detects/uses the 1st CPU.

but it do support the hyper-threading technology,
when your M-board suports HT and you have a HT CPU,
then the XP HE will see/show 2 processors.

Hyper Threading is a Logical 2nd CPU not a physical one and machine before XP Win 2k I think, NT 4 I know, Would see it as 2 CPU's and not use it properly, I'm just waiting for the Dual core CPU's and see how that will work out

Windows XP Home DOES support HT.
