Power limit is not permanent #178

Closed x51don closed 1 year ago

x51don commented 1 year ago

Hi,

I'm "usinng undervolt -p1 40 30" and it is changing power limit to 40W for a while, but when I stress CPU for longer time it reverts to 45W.

It stays 40W when there is no load on the CPU.

yes, sometimes your computers SMC will reset the controls. you can use the systemd timer described here to re-apply continually: https://github.com/georgewhewell/undervolt#running-automatically-on-boot-systemd
