I have a Pentium D 3.4Ghz HT cpu in device manager it shows 2x CPUs but in taskmanager it only shows one. Not that this seems to be a problem in anyway but I wanted to make sure the settings are correct...

Is there a way to fix this?

I am running Windows XP Pro SP3 32 bit

There is a change you need to make in the Task Manager.
Please look at picture attached for instruction.
Let me know if this helps
Apparently I'm having trouble attaching...
Open Task Manager,
under view, select CPU history, and then "1 graph per CPU"

Pentium D CPUs do not come with HyperThreading, save for the Pentium EE 840, which runs at 3.2GHz so you do not have that IMO. You likely have a Pentium 4 HT, with two logical CPUs but a single physical CPU (not the same as a Pentium D, which is a dual-core CPU).

So why do you want to see two graphs in Task Manager?

SIW lists it as a Pentium D 945 single core 64 bit CPU

Under device manager it shows 2 cpus so it either has to be a HT capable CPU or its a dual core and SIW is lying to me

Either way I am confused.....

No reason why I want to but isn't that how it is suppose to look?

EDIT: Everest lists it as a Pentium D 950 Dual Core 2.4 GHz

Both are dual-core and have the exact same frequency. How SIW shows it as a single-core CPU is beyond my understanding.

Wait for others to reply. I can't manage to pinpoint the problem.

I may have a reason which i may fix in a month or so - the OS on the other computer was installed on a different one previously and I haven't redone it yet because its working fine as is until i can get an 64 bit OS to install om the new hdd I bought for it

So I have a dual core CPU then? So they are both 3.4 ghz cpus? or how does one tell how fast a dual core cpu is in comparison?

I've had a pen D processor back in 06 and there are two cores, lacking Hyper threading, unlike the pentium 4 with HT technology. If you are looking at older cpu's they HT works totally different with intels newer cpus. Yes you do have 2 seperate cores running at 3.4ghz, but no ht, your problem is kind of beyond me. I'm definately looking into it now though.

Sweet Thanks to all of you

So I am guessing the newer multi cores have HT then?

I am new to all of this multi core stuff so thanks to all of you for your help

yeah i own an i7 920 as you can see, and the HT on the new cpus is 30-40% more productive in some applications, oppose to the meager 5%~ boost in the old ht models. I burn a blue ray disk in 1 and a half minutes, really impressive, and i use pinnacle ultimate for video editing. It takes about 55 seconds to encode a 2.5g disk.
