Hyperthreading?

Mike777 · 08-20-2005, 01:33 PM

Can someone tell me how to disable Hyperthreading on an HP Pavillion 764n with Windows XP home?

I recently bought Pro Tools 6.9 LE and I'm having some problems setting it up. I was told that disabling hyperthreading might make it run more smoothly..
Thanks

Should be a option in bios to disable h/t

Thanks!

You get into the BIOS by hitting a key as soon as you turn the computer on. There are basic instructions here. I think the correct key is F1 for HPs. Once you get into the BIOS just look for an option called "Hyperthreading". It should have two options: "Enable", and "Disable". Set it to "Disable". Then save your BIOS settings and reboot.

You can tell whether you've done it properly by hitting ctrl-alt-delete and then select the "Performance" tab. If you see one box under "CPU Usage History" then hyperthreading is off. If you see two boxes side-by-side then hyperthreading is on.

By the way, most of the time people tell you that disabling hyperthreading may help it doesn't make any difference. Only some old drivers had problems with it. Recent software has to work with hyperthreading enabled or the software developer is in for lots of misery.

someone correct me if im wrong but ive heard somewhere that the windows xp pro edition only takes advantage of hyperthreading and not the home edition.

Home edition can utilize h/t. Im doing it now.
