Failed to get frequency

Overlord1310

Hi, good evening.

As mentioned in the title of this thread, I’m having trouble selecting the CPU frequency.

To start with, as shown in the video, the maximum frequency of my laptop’s processor is 3.4 GHz — or am I mistaken?

It also shows that with Turbo Boost enabled, the maximum allowed frequency is 2701 MHz. However, in the list of available frequencies provided by sysctl, 2701 MHz doesn’t appear.

And when I try to select any of the available ones from the list, it doesn’t let me, as shown in the video.

I’m trying to understand what’s going on, since I’m currently tweaking the acadapter script in powerd for power management. This is how I have the script set up at the moment:
