How do enable Hyper threading in XP Pro?

post #1 of 7
Thread Starter 
Moments ago I installed my new CPU, a 3.06 GHz P4 socket 478 Northwood core with hyper-theading.
I enabled hyper-theading in my bios.
How do I now get windows XP to now enable hyper-threading?
When I contol-alt-del and click the performance tab windows still shows only one CPU.

I would imagine someone out there knows what I do next.

Thanks,

Meritman

When Hyper-Threading is enabled in the computer's BIOS, Windows XP automatically upgrades the hardware abstraction layer (HAL) if it must use a multi-processor HAL, and an additional processor or processors may be installed and listed under Processors in Device Manager. The system will prompt you to restart so that the new settings can take effect.
The above quote was taken from here.

Essentially, when HT is enabled in BIOS (as you have done) WinXP should automatically start using it without any manual configuration from the user.

If HT doesn't appear to be active on your install of XP after you have made sure to enable it in BIOS and saved the BIOS settings before exiting BIOS, then there would appear to be a problem with your system, or with task manager's display.

Try downloading and installing Speedfan which should show two bars in it's CPU usage display if HT is enabled. You could also try downloading the Intel HTT Test Utility which will determine if HT is enabled on your system.

If you find that HT isn't enabled in Windows, but that you have indeed selected it to be enabled in your BIOS, perhaps it is possible that you don't actually have an HT CPU..?

Hope this helps.

Like said above Windows XP automatically will start using the HTT as soon as its enabled in the bios. Unfortunately All operating systems under XP do not incorperate the HTT feature

Well im not hi-jacking this thread people but i have a question now related to this..I just downloaded the HTT test program above and it tels me that my CPU is ready and my bios is ready but then it has a query at my chipset..I have HTT enabled and seems to be working fine..Could it be a program glitch?

This is what i get : ADVISORY! The Hyper-Threading Technology Test Utility

was unable to identify if all the core components are present, turned on or functional in this system.

Without all required components, Hyper-Threading Technology is not fully enabled.



Processor test:Passed

Chipset test:Did not pass

BIOS test: Passed

Well no to worry i found out that regardless of what intel tells me my Hyperthreading is fine and working this is because if you look in your task manager and under the performance tab if you look at the cpu usage history and there is 2 boxes that means your HTT is on and working.

Hmmm... Yeah, I must admit I have had a similar problem with the HTT test Utility querying my old ASRock chipset. I think it does this if you don't have an intel chipset. I guess they just didn't build in support for other chipsets..? Still, it's worth a try as it may work.

Yes i believe the utility will only detect the ''Intel'' chipsets as such..I have verified that my HTT is on and working.
