New Post: Set CPU Core Affinity for Handbrake

your calculations are correct, it's based on the same logic.

However I hope you've read the documentation carefully. When you click STOP MCEbuddy writes the EXISTING configuration back to the file.

When you click START it reads the configuration from the file.

So if you're making changes without clicking stop you will lose your changes.

Click, Stop, make the changes, click Start.
