Can you pick and choose which CPU cores to use?

Don't question why I'm asking this, I'm was just wondering. But if you had a 18 core processor (for example) and you (for some reason) wanted to just use the 1st core and the 18th core and disable all the rest, would it be possible?

You can certainly disable cores, thats how people hit record OCs. Disable every core but one and you can hit 8GHz+ under LN2.

you can assign a program to only run on specified cores.
It's called core affinity.

The mechanics of how it is done will depend on your OS.

Nowdays the the schedulers are prestty good and it would be an unusual situation where you would benefit from manual core assignement.

So do you (or anyone reading this) know how to manually assign cores?

In windows 10.

Did you follow the instructions in the link?
That's what I do for a running task.

If you want to do it at program start then you would use the cmdline start command.
sot start /Affinity <hex mask>

Sorry. For some reason I didn't read your link. But it actually helps so thanks!
