HyperThreading not working

I recently purchased a P4 3.0ghz Processor. I opened the
task manager and checked the performance tab and it only
has one window for cpu usage history. I have looked at
quite a few sites including my Mobo's manufacturer's as
well as Intel's and I can't find anything about it.

My system is as follows.

Windows XP pro SP 1
Asus P4C800 Deluxe (lastest bios 1101 I think)
P4 3.0ghz @ 800mhz
512mb pc3200 DDR-Ram
ATI Radeon 9700pro (Cat 3.8s)
Creative Sound Blaster Live! platinum
WD 120gb HDD
Maxtor 60gb hdd

If anyone knows how to fix this please help.

Thanks in advance,
John
 
Did you enable hyperthreading in the bios? On mine it was disabled by
default and I had to enable it.
 
Two things - in Task Manager's Performance tab, make sure
that under the View menu->CPU History that "One graph per
CPU" is selected.

If you still only see one CPU, check your BIOS and make
sure hyperthreading is enabled there.
 
Checked the taskmanager and it says that 'One graph per
CPU'. It is enabled in my bios and I have to listings
for the CPU in the device manager. But Sandra reports
that it is off and the taskmanager only has one window.

I was check around and it seem that I should have a "Uni-
processor or multiprocessor" listed in my device manager,
however it doesn't. I don't know if that could be the
problem.

Also a friend of mine suggested a reformat but thats a
bit extreme.

I have the same board, you did check to make sure you
enabled hyper-threading in the bios ? that should be the
only setting you need to set to enable hyper-threading.
 
Yes I understand that that should be all I have to do,
but it apparently isn't. I have had it enabled since I
installed it. I don't know what to do short of a format,
and I don't want to do that. So please is there
something in windows I can change that will enable Hyper
threading?

This is a guess based on switching from one physical
processor to two physical processors.

You may need to do a repair installation to switch from
the single processor HAL (Hardware Access Layer)
to the multi-processor HAL.
