** Description changed: When I boot with this installed frequency scaling is no longer behaving as expected. It seems that with this installed, the OS loses control of the scaling. It seems that scaling is performed, though. And very much to the purpose of power saving. Performance is terrible because of this. And I do mean terrible. - It makes it so that there are two governors available, powersave and - performance. + The default governor is powersave. - And I can seemingly switch between them, but setting performance (yes, - on all cores) doesn't seem to change to scaling behavior. The frequency - doesn't pass 800MHz. + Setting the governor to performance (yes, on all cores) doesn't seem to + change to scaling behavior. The frequency doesn't pass 800MHz. I would like to use Intel's microcode updates, but I have to have my CPU running at the speed for which it costs so damn much. Any suggestions?
