Probably all maximum frequencies can also be seen via:

Code: Select all

vcgencmd get_config int
Sure, here's the output while stress test (cpu & ram) was running in another screen:

Okay, so it is only the CPU frequency which was raised. GPU runs at default frequency: https://www.raspberrypi.com/documentati ... erclocking

Good to know that this seems to run stable now without overvoltage. Our profile which matches these frequencies still applies +2 overvoltage. Looks like this can be enhanced a little to reduce power consumption = head dissipation :).
