I've installed Ubuntu Server 16.04 on an Athlon 5050e with an Asus M2N68-VM MB. Everything works fine and fast with my Avant SSD, but the energy consumtion is about 60 -80 Watt, which is quite a lot!
I've browsed the web and found out that AMD has a feature called 'Cool And Quiet', so I activated it in the BIOS and reinstalled Ubuntu Server.
And: nothing changed! This is what I figured out:
I went to /sys/devices/system/cpu/cpu0/cpufreq
and printed cpuinfo_min, cpuinfo_max and governor.
- min speed is 1GHz
- max speed is 2,6GHz
- governor is set to 'ondemand'
Everything looks fine but 'time_in_state' shows that the CPU is running on max. speed - all the time.
Maybe you can help me, solve this problem. I can't see what's wrong.
cpufrequtils
and runcpufreq-info
? Than you'll see the current frequency on all processors.current CPU frequency is 2600 MHz (asserted by call to hardware)
top
to see what is taking up the CPU?htop
confirms that cpu-load is about 0,9% (which is used by htop).powersave
