With the very latest firmware the GPU can be overclocked.
What exactly do you mean by the very latest firmware? I'm observing the same problem with setting core_freq=600
vcgencmd measure_clock core
shows only 500 for current raspberrypi-kernel-1.20200212-1
(4.19.97-v8+ #1294) and also for today's rpi-update
However, for the randomly backed up version (created by rpi-update
on 15-Aug 2019) it works. It seems that the latest firmwares lost the overclocking ability.
