I've been gifted an ASUS Republic of Gamers (ROG) G750JX laptop but am having a
problem with it. It seem to ignore:
sudo /usr/bin/cpufreq-set -r -g performance
and instead always runs in ondemand mode.
It has a base speed of supposedly 2.4G, but actually runs at 2.3 or less and
very occasionally hits' 3.4G, just *after* Xruns.
There is nothing in the bios I can find regarding CPU frequency
Any suggestions?
Maybe related to intel cstate or pstate drivers. I use Liquorix kernel
which defaults to disabling pstate with intel_pstate=disable and I add
intel_idle.max_cstate=0 processor.max_cstate=1 to disable cstates. It
also defaults to performance governor.
An interesting page on cstates:-

You can check which driver is being used:
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver
Mine says acpi-cpufreq
