Hi friends, I am trying to downclock my OPi Zero and set/disable unused cores 1,2,3,  limit DRAM speed, limit max cpu core frequency, put voltage down. 

Is this possible on Opi Zero? 

 

I tried e.g. 

Quote

echo 0 | sudo tee /sys/devices/system/cpu/cpu3/online > /dev/null

 

but when I cat /sys/devices/system/cpu/cpu3/online is is always 1. Any idea please?
Some advice how  to do all of this is highly appreciated.

 

I am trying to downclock Opi Zero to push produced heat down.

you might want to try h3consumption utility.

Thanks gnasch! But I read h3consumption works just with H3 boards only and Opi Zero is H2 board. Will it work with OpiZero in this case please?

H3 and H2 are almost the same chips.
