Based on https://github.com/monkins1010/ccminer/tree/ARM
I recommend using the latest release of Armbian for the Rock64 (https://www.armbian.com/rock64/#kernels-archive-all)
Overclocking: With older releases of Armbian, Overclocking is done with the below commands
sed -i "s/MAX_SPEED=.*/MAX_SPEED=1510000/" /etc/default/cpufrequtils
service cpufrequtils restart
But on the latest version you can overclock with armbian-config.
