disable multicore usage automatically

Hello Jamali, and welcome to Seven Forums.

You can manually set the processor affinity for a program like this, but once you close the application or restart your system, Windows forgets your set affinity and automatically sets back the default affinity of the application running on all available cores of the processor.

Hope this helps,
Shawn

Hi,

Im not sure how much this will achieve, but you could try the following:

1. Open Task Manager
2. Click the "Processes" tab
3. Find the executable for your application under the column called "Image Name"
4. Right-click on the executable, and select the "Set Affinity" option
5. Remove the ticks from the processors you do not want to use.

See attached image.

Longer term you may want to invest in a cooling option (e.g. USB cooling pad) for your laptop, or give it a good clean.

Regards,
Golden

hi shawn
yup thats the problem, when restart the pc it will set back to the default processor affinity. need to redo whole things from the begining. kinda time consuming.

hi golden. currently I am using notepal u2 for my laptop, it help a bit by reducing 2~3 c . need to disable lot apps if I want to play NFS or even CS . my dell 1464 will start to shutdown itself after 10 minutes ++ of playing.

Your could also do what's in post #7 there to create a .bat file to be able to run the program's exe file with the processor affinity you set in it.

You do realize this won't help you at all? Right? This won't make your CPU run any cooler.

Agreed. You would be much better off to improve temps by increasing airflow with better fan cooling, and to blowout the vents with a can of compressed air.

There is a utility called Prio that will allow you to set the affinity and per program priority. And it remembers the settings through re-boots.

It is accessed from within Task Manager, so it's very convenient.

As the posts above suggest it may or may not help your temperature issues.

In any case, here's the link: Prio - Priority Saver

Hope this helps,

I must admit that I've never changed the affinity settings, so I didn't know.
From my experience, the priority settings are definitely retained between boots.

Glad this was helpful,
