dietpi-preboot is running, no extra software installed
Hmm it works well here, that is strange:

Does this directory exist in your case?
ls -l /sys/devices/system/cpu/
And can you show loaded modules with lsmod, to compare with the ones I have laoded?

rockchip_cpuinfo might be the scheduling driver, but not sure, actually I'd expect it to be builtin.

rockchip_cpuinfo seems to be loaded...
Weird, exactly the same kernel. Should not make a difference, but can you try to flash the bootloader image:
sudo /boot/dietpi/func/dietpi-set_hardware flash-u-boot-mmc
Is the issue still present with latest kernel and bootloader (flashed with above command)?
Bootloader update didn't help. I ended up returning the board, it seemed to be hardware issue. With new board it worked flawlessly straight out of the box.
I found one user who reported same problem on their Radxa Rock 5B board, which shares the same chipset - i guess it's manufacturing defect.
Seems so. Though strange hardware defect when the system boots and works, but only CPUFreq does not.
this is the link to radxa forum, https://forum.radxa.com/t/rock5b-dmesg-pvtm/13859
my understanding is that the pvtm part of the cpu was not working properly, and as a result the CPU ran normally, but underclocked (?) B/c my board had the exact same issue with low geekbench score
Here another article about this, interesting: https://www.cnx-software.com/2022/07/17/what-is-pvtm-or-why-your-rockchip-rk3588-cpu-may-not-reach-2-4-ghz/
