- (OKAY) with "arm_freq=1200" and "sdram_freq=450" --> system was running very stable - but also not very performant of course.
- (not OK) with only "sdram_freq=450" --> system already had the first reboot (= instable)
I spent something between 11 to 13 hours during the last week for investigating and fixing (e. g. almost 10 external fsck’s necessary putting the SD card to another pi) all the issues coming from this unstable system on the Pi 3 B+. I‘m therefore very frustrated (first time in 5 years of Pi experience) and I think about returning that piece of faulty Pi hardware and get another one. I want stability AND performance - and spend my time for more important things -.-
So the situation with even having a stable, but slower system (1.2 GHz core freq, 450 MHz sdram freq) is not satisfying. Might be the next Pi 3 B+ has the same issue, but as I read (here and on other places) that some users have two or more Pi 3 B+ and not all of them have theses issues, at least there´s a chance, right.
