OPI lite 2 minimal cpu frequency

[cond080]

hello , I have Opi lite 2

 

I want to use it as low load server with minimal power consumption (min temp)

I edited  /etc/default/cpufrequtils  like that

 

min_speed=120000

max_speed=480000

governor=ondemand

 

but it works on 888mhz constantly  with load and without load  (image 2)

 

Ps: I have also OPi PC+  and  edit of cpufrequtils  works  ok on it  (image 1)

 

what am I do wrong, or maybe armbian-config  monitor doesn't work properly ?
