Atom 330 reporting only 1 core (expected 2) [SOLVED]

[phugo]

Hi there,

Have a Zotac motherboard with Atom 330 on it (dual-core 1.60 Ghz CPU) which shows only as 1 CPU in Task Manager.

With hyperthreading enabled, I would expect to see 4 different graph/threads in Task Manager.

Same thing is reported by CPU-Z, 1 core, 1 thread.

What could cause this ? Windows did not detect the CPU properly on install? (is it worth try re-installing?) Defective CPU ?

OS: Windows XP SP3 32bit.

I'm new here, I've seeked help on the Zotac forum with no luck so far so I tried to find a more active CPU-oriented forum which seem the be the case here.

Thanks in advance for any hints.

Hit start, type msconfig, press enter, click boot tab,click advanced options, is the number of processors box ticked or unticked? If it is unticked try ticking it and setting number of processors to 4.

By the way this belongs in computer help.

Sounds like a single processor HAL is installed doing Windows setup.

How to force it under installation, if you wish to reinstall instead:

My apologizes for posting in the wrong section.

I did check the boot.ini as you suggest. The NUMPROC line was unticked, when I tick it I was hoping to be able to change it but unfortunately "1" is the only available choice.

Also, weird that in Device Manager, I see this:
Intel ® Atom ™ CPU 330 @ 1.60Ghz
Intel ® Atom ™ CPU 330 @ 1.60Ghz
Intel ® Atom ™ CPU 330 @ 1.60Ghz
Intel ® Atom ™ CPU 330 @ 1.60Ghz
So it seems Windows does see the 4 threads somehow but for some reason does not use them properly...

Can you explain the last part in abit more detail?

In terms of the taskmgr. Make sure you just havent selected 1 graph for all CPUs.

Heh, I didn't know you can do that. Learn something new every day.

What I was trying to say is that I found it odd that Device Manager was showing 4 lines (threads) but that Task Manager showed only one.
About the View settings in Task Manager, it is set to "One Graph per CPU" (no other choice available anyway in my situation).

From device manager:

About the link http://incore.net/winxp-multicpu/, it sounded interested but looking on my system, the files that the guy tells to replace are already present on mine. (i.e. HAL.DLL, ntoskrnl.exe, ntkrnlpa.exe are already there and the older files he mentions are not present at all).

I guess I'll try a "repair" trough the XP installation disk or end up trying to re-install.

Thanks.

Is the XP a clean install with the Atom? Or did you move it from something else?

It sure looks wierd, but it seems to be a software issue.

The XP was a clean install...
Having decided to re-install, I decided to upgrade to Win7-64bit.
Task Manager shows 4 threads and needless to say the machine is much more responding now...

Good to hear
