I was wondering if there was a way to tell if both cores of my processor are running? I have Windows XP Professional.

Sorry for becoming a bit of a question slut. :X

you guys give the best feedback, so i can't help myself, thanks. :cool:

Well, I don't think it's even possible for only one core to run, I think if there was a problem with one core, it just wouldn't work.

But, I suppose for good measure, you could press ctr+alt+delete, then click the performance tab. If there are two active (at all) graphs labeled "cpu usage history", then you have two cores. If there is only one graph, then for some unexplainable reason your cpu only has one core.

Good luck ;)

Yeah, Task Manager should show how much activity there is on each core. You can actually disengage one core in both HyperThreading and dual core CPUs by setting Affinity. I think what happens when non threaded apps run on dual core is both cores are active but only one is actually doing the work.

Sweeet! I had no clue what "set affinity" meant.

Interesting they have checkboxes for up to 32 cores...

another way is to go into your device manager and expand the processors section, if theres two processors in there your good to go

Well realistically setting affinity is only necessary when a program that is optimized for dual core or drivers for the dual core CPU are buggy and a patch or update is being waited for. It could also be used to compare single to dual core performance though.

I think setting affinity is also useful for when you want to multi-task, and disable, for instance, a game/app's ability to use one of the cores. Some apps, like those that transcode DVD video or P2P apps, love to eat up both cores. Not that I could know such things firsthand, because that would be illegal and wrong. Terribly wrong... :lookaround:

Personally though, I leave affinity alone. I multi-task and let the cpu figure out where to apply the load. Dual cores totally rock! I can't wait to get a quad core.

It's silly to try and use affinity for a dual core processor. It's meant for seperate processors to use different cpu's so that one isn't handling all of the load.

The way to disable dual core from running is in the bios. It's on by default.

Get Everest or Aida32 or CPU-Z, you can see there all about your PC
