C-states supported?

[mweis]

i just measured the power consumption and was a bit irritated it was so high. then i checked the frequency of the cpu...

 

 

is this normal?

By default the CPU scaling governor is set for performance, you can set it to powersave and the CPU will downclock easier, but note that it won't downclock much under any significant load, I found around 10w total savings from both my always on servers when set to powersave.

 

echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

 

Repeat for the other cpus, until cpu7 for you server, if you like it you'll need to re-apply after every reboot, you can do it with user scripts.

Sorry, wrong setting here, it should be

 

echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

i only get this:

 

root@AnaNas:~# echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
-bash: /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor: Permission denied

Don't copy/paste directly from the forum, it can introduce extra characters.

Install the Tips and Tweaks plugin for a non-command-line way to do it.

Yes, forgot about that.

i have done this, but the plugin says powersave is enabled .... but states are same...

[testdasi]

did you change the profile under intel turbo boost section of the plugin?
