Hyperthreading CPU but 2nd "CPU" not shown

[Guest John7]

Hi,

 

 

 

On a customer's system the second "cpu"does not show although:

+ CPU supports hyperthreading,

+ BIOS has hyperthreading enabled

+ ACPI 2.0 enabled.

+ Windows "ACPI multiprocesor-pc" CPU device driver manualy selected.

+ New hardware detected, 2x reboot.

 

But in Device Manager still 1 processor listed.

In Task Manager still 1 Performance Window.

How to fully enable hyperthreading ?

 

 

System description

P4 3GHz with hyperthreading.

2GB DDR400

WinXP Home + SP3

Office 2007

All updates

NOD32 A/V

RocketDock desktop enhancement

 

 

TIA,

John7

Re: Hyperthreading CPU but 2nd "CPU" not shown

 

Some Confusion - hyperthreading permits "one" processor to process more than

one thread concurrently (providing application is programmed to take

advantage).

 

Hyperthreading by itself does not indicate multiple cores or processors.

Re: Hyperthreading CPU but 2nd "CPU" not shown

 

What you say is true but a hyperthreaded processor will show up as two

logical processors in the Device Manager.

Open task manager..performance tab..view button..and under cpu history be

sure 'one graph per cpu' is picked.

To all,

 

Please stop this architecture discussion.

I am trying to get a new customer's PC fixed.

 

Technical details described in initial post.

Please read first.

 

Additions:

- Asus P4PE2-X bios 1004

- 2x 512MB DDR400 (checked OK)

- Maxtor 160GB HD

 

According CPU-Z

P4 Prescott 90nm

Fam/Model/Step : F / 4 / 1

xFam./xMod./Rev: F / 4 / E0

 

Core 3GHz

Mult. 15x

Bus 200MHz

FSB 800MHz

 

 

Thank you.

Re: Hyperthreading CPU but 2nd "CPU" not shown

 

Do a Repair or In-Place install and do not forcibly select the HAL.

If the Motherboard is ACPI compliant, it should inform XP that it

can support HT enabled processors and select the right Computer

driver.

 

Also making demands isn't welcome here, especially since you are

working for pay on this problem.

Install the chipset drivers and update the processor drivers.

You manually installed a driver for "ACPI Multi".

 

Have you done the windows updates since, not the express ones, the

custom ones and then the optional hardware ones?

 

Have you also updated your BIOS to the most current version?

Judging by what I see here, I like the sound of your BIOS upgrade theory.

There is a 1006.001 available on the download page.

 

http://support.asus.com.tw/cpusupport/cpusupport.aspx?SLanguage=en-us&model=P4PE2-X

 

Also, read the warnings for each BIOS in the BIOS list.

 

http://support.asus.com.tw/download/download.aspx?SLanguage=en-us&model=P4PE2-X

 

Good luck,

Paul

Re: Hyperthreading CPU but 2nd "CPU" not shown

 

if the processor is AMD, have you ran the dco? available from their website

that is if it's a processor upgrade from single to dual core.

RESOLVED: Hyperthreading CPU but 2nd "CPU" not shown

 

To all,

 

Thank you all for your help.

 

A BIOS update to v1005 did the trick.

Release notes do not mention this bug fix.
