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?
Unfortunately neither of those suggestions worked.
What seems to be happening is that when idle the machine lets me set higher
frequencies, but as soon as it starts to do any work, the settings are changed
to lower values, and then may be increased again... too late!
It's more-or-less OK, running 48k 128frames 3buffers into a KA6
This is an intel i7. A considerably older intel i5 runs quite happily with the
same workload running 48k 64frames 3buffers (also KA6).
I have been using the parameters in the intel_pstate driver to tune cpu
frequencies...
/sys/devices/system/cpu/intel_pstate/
in particular max_perf_pct, min_perf_pct and no_turbo
