How can I overclock orange pi pc image?

    hey, I'm trying to overclock my orange pi pc, i searched for a bit and found that i could use device tree (DTB) but I'm really lost on how I can change the frequency, is there any documentation or something like that to change the frequency?

    Or even ready DTB files for specific frequencies, in armbian there are already pre-defined frequencies that work great

    Yes, you just need to add additional CPU operation point, either by editing DTB file or via DT overlays. Why would you want overclock your board? It doesn't give you much benefit for LE purposes.
