Only one core working on Q6600?

[fross]

Hi there,

just installed my Q6600, and my 3dmark scores have not been consistant with what everyone else has been getting, so I've been delving a little.

One thing I just spotted is under CPU-Z, at the bottom of the CPU screen it claims I only have 1 core?

Name: Intel Core 2 Quad Q6600
Code name: Kentsfield
(etc etc)

Selection (Processor #1) (greyed out)
Cores: 1
Threads: 1

Is this really correct? In Task Manager, I also only have one CPU Usage graph. If so, what could/should I be looking into to enable the other cores? I am running Windows XP 32 bit, if that helps.

Thanks,

David

It's not a new build, ported my HDs over. I really don't want to reinstall windows if I don't have to.

I've looked up the ACPI Multiprocessor thing, and I'm definitely running a non-multiprocessor one, so that's the issue. However, I can't seem to find a driver for it, if I select that and choose "Update driver" I only get the option of "ACPI PC" or "Standard PC"!

That worked a treat! Thanks!

2 out of 4 is weird, it implies it isn't a single processor build, but the others are still being missed?

What operating system specifically is he on? I know NT only used to be able to recognise 2 processors for a while, perhaps an entry level version of XP or ME is limited to 2 as well?

That sounds like a good candidate then.

On the subject, thinking of upgrading to Vista soon - is the cheap version of that limited to a certain number of cores too?
