I was reading a thread about seeing if all the cores are operating properly.

I looked in Dev Mgr and it shows 8 cores, but usage on only two.
Is this normal?

Thanks,

Paul

Indeed it is, Windows dynamically adjusts core usage across the cores according to demand so don't worry about it...

Your task manager shows 8 graphs, and your specs indicate you have quad core i7 2600k which is hyperthreaded so that 1 core is assigned to 2 logical cores and can work on two threads simultaneously, thus appearing to the system as 8 cores...

Hope that helps..

EDIT: If you want to see all 8 cores in action, try using this software, It'll force all eight logical cores to work

Unzip it, run LinX.exe with your task manager open, and start it up... watch the graphs then...

Thanks for the info.

I ran the program and all 8 cores went wild and the CPU went to 100%%.

I'm glad that they are just operational, if needed.


Tried to add to the rep - said I had to add it around first.
I guess it is because I gave it to you on your previous reply a dew days ago.
Sorry.

No worries mate, always glad to help!

Also, keep that software in your utility toolbox for future diagnostics incase you want to test for stability and temperatures at peak load.
