Thanks.
Afaik there are no proprietary kernel modules in the default buster install and
I did not install proprietary modules either. BUT I did install proprietary
firmware for the devices.
First I only installed firmware-amd-graphics as it is necessary for XServer to
work. But the same GPU was already present in my previous desktop system.
After I noticed the issue with memory I also installed in that order
·firmware-realtek for the ethernet controller
(The controller does work without it, possibly not at full speed, but it
works fast enough for my connection)
·amd64-microcode for the CPU
But this does not seem to have made any difference. Beside these 3 package the only other installed package from non-free is a font-package.
Here's the lsmod output
(while some programs are running in case that's relevant):
