| Jan 25, 2020 at 9:55 | comment | added | rogerdpack | Sadly doesn't work for me either. cpupower frequency-info has bizarre output like frequency should be within 1.20 GHz and 1.20 GHz....current CPU frequency: 3.16 GHz maybe it's the funky laptop I'm using [dell inspiron]. The only change I notice is if I change /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq then my idle freq. goes down slightly. Under load all cores still go all the way to the CPU max :( | |
| Nov 21, 2019 at 3:30 | comment | added | jberryman | How are you verifying that performance governor actually sets a constant cpu frequency? When I do watch -x grep -E '^model name|^cpu MHz' /proc/cpuinfo the numbers bounce around all over, even when I change the governor to performance | |
