First post out here
I want to run my desktop (running linux debian testing) cool and silent.
Slow is not a big issue.
[Just for context it is 40 deg C or 104 F out here nowadays!]
Now Ive done this in the past with various laptops:
cpufreq-set -u something
This clamps the highest clock freq to whatever is given.
Thereafter the laptop runs slightly slower but much cooler and less noisy.
However with my desktop this is not working.
Output of cpufreq-info is
Code: Select all
$ sudo cpufreq-info
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpufreq..., please.
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 2.40 GHz - 3.00 GHz
available frequency steps: 3.00 GHz, 2.40 GHz
available cpufreq governors: userspace, conservative, powersave, ondemand, performance
current policy: frequency should be within 3.00 GHz and 3.00 GHz.
The governor "userspace" may decide which speed to use
within this range.
current CPU frequency is 3.00 GHz (asserted by call to hardware).
cpufreq stats: 3.00 GHz:100.00%, 2.40 GHz:0.00%
analyzing CPU 1:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 1
CPUs which need to have their frequency coordinated by software: 1
maximum transition latency: 10.0 us.
hardware limits: 2.40 GHz - 3.00 GHz
available frequency steps: 3.00 GHz, 2.40 GHz
available cpufreq governors: userspace, conservative, powersave, ondemand, performance
current policy: frequency should be within 3.00 GHz and 3.00 GHz.

cpufreq stats: 3.00 GHz:100.00%, 2.40 GHz:0.00%
However I am unable to set it to 2.4 GHz
Any ideas?
