This is a short script for changing the CPU clock rate of the Banana Pi M3 in the allowable steps between 480 MHz to 1.8 GHz.
Since the Banana Pi M3 heats quite a bit at 1.8 GHz (even with heat sinks), lowering the CPU frequency can bring these temperatures down. The clock rate can be tuned between 480 MHz and 1.8 GHz by default, possibly up to 2 GHz when the CPU voltages are adjusted and unlocked.
Note: This script only adjusts the speed up to 1.8 GHz.
- Download the script from Pastebin [Direct Download]
- Copy it over to your Banana Pi M3
scp BananaPiM3_FrequencyChanger.sh user@bananapi:/home/remoteuser/
- Make it executable
chmod +x BananaPiM3_FrequencyChanger.sh
- Run it with
Optional: Add an alias in your .bash_aliases to call it faster!
echo "alias frequency='./BananaPiM3_FrequencyChanger.sh'" >> .bash_aliasesApply the changes with,
source .bashrcFrom now on you can call the script with
