Try the command "cpufreq-set" like the example:
cpufreq-set -c 0 -u 800MHz
or any frequency your cpu can use.
I added this command to a little shell script named "cpufreq-min.sh" and copied it to /usr/bin/
So the cpu is forced to stay low on frequency. There is another script, called "cpufreq-max.sh" which does set the opposite, I guess you know the trick.
Note: You must set each cpu seperately, so if you got i.e. 4 cores, your sript will need 4 lines for each core, like:
---
#:/bin/bash
cpufreq-set -c 0 -u 800MHz
cpufreq-set -c 1 -u 800MHz
cpufreq-set -c 2 -u 800MHz
cpufreq-set -c 3 -u 800MHz
---
This got the advantage, you can control each core seperately.
Hope this helps.
Best
