Rock 5B CPU/GPU Overclocking

#1

Hi,

How would one go about overclocking the CPU and GPU on the Rock 5B?

I figured it would require a device tree overlay but I don’t know how to create the overlay for this.

#2

The overlay depends on the system you’re using. Which distribution is it?

#3

I am using Debian Bookworm 12

#4

Which debian bookworm. Radxa, armbian, other?

#5

Sorry, its the radxa one, I got it from the github page: https://github.com/radxa-build/rock-5b/releases

#6

I will try to look at the device tree, meanwhile you can probably tag some Radxa employees to help you (not so with armbian)

#7

Thank you, I actually forgot to tag some Radxa employees

@RadxaYuntian would you be able to give me some direction on this perhaps?

You can modify the OPP table and see what happens. There are multiple levels since RK3588 uses PVTM to further reduce the clock speed.
