[Volunteer needed]Too high DRAM clock speed MAY be causing you random crashes/freezes

[Narvod]

Hi,

I'm running Mobian (so default is 552Hz, right?), and although it is pretty stable, I still have random crashes from time to time. So I would like to try a different dram clockspeed to see if it can get even more stable !

But this post is not very recent, so I've got a few questions :

1. are the packages in the OP still usable today, or are they now outdated? 
   
2. I can see on the git release page of Arch for the pinephone that they provide a modified u-boot as well, do you know if it's up to date and safe to flash for Mobian as well?
   
3. in the same spirit of 2, the command they use for flashing u-boot is with dd is almost the same as in OP, except with `bs=1024 seek=8` and not `bs=8 seek=1`. What difference does it make and is one better than the other? 
   
4. If I flash the modified u-boot, I suppose I won't be able to update it when an update is available on the mobian repository?
   
5. How can I backup or find the original u-boot that comes with Mobian, so that I can revert back to it in case something goes wrong, or if I want to install an update of u-boot from the Mobian repository, if/when there is one ? (I tried `dd if=/dev/sdX of=uboot-backup.bin bs=8k seek=1` as suggested here but ended up with a Backup of more than 1go so I stopped the process. I also found u-boot binaries under /usr/... but I am not sure which one is the one I want )
   
6. and last but not least : do you think this issue is going to be solved upstream at some point, or will some of us always need to mess around with the ram clockspeed to get a stable system ? In other words, should I wait that this issues is solved by the devs, or is changing the clockspeed my only option? ^^'
   

And that's pretty much all I.d like to know

Edit: I've got the posmarket os convergence (3go RAM) community edition
