As soon as you receive an error, you can abort.
Remember to test all 4 banks with a fault-free RAM stick to rule out the possibility that the motherboard is broken.

So… the tests can be made with pairs without any problems.
When I mount all 4 banks, memtest86+ crashes and the PC restarts.
Same thing with stressapptest from CLI, after a couple of seconds the PC restarts.
Memtest says that, if the rams were tested individually, most of these problems are due to the BIOS and many BIOSes have these problems with 4 banks of DDR5, even disabling any overclock and enabling Memory Context Restore.
It’s really becoming Don Quixote’s battle against windmills 
…
I just tried an ffmpeg encoding from mp4 to avi and the PC restarted…
That’s completely absurd.
If the 4 RAM sticks are identical, then they should work without any problems.
Have you tried “MEMORY TRY IT” in the BIOS?
Does the mobo have a dual BIOS so that you can test a different BIOS version?
If the RAM sticks are OK, then it’s probably the BIOS or motherboard.
Do you have a friend with a suitable mobo that you can test the RAM sticks on (or vice versa, other RAM sticks in your mobo)?

no unfortunately I don’t have anyone to change the motherboard with. Now I reset the BIOS and ffmpeg works without problems, I’ll try memtest86+ again. I had seen MEMORY TRY IT but not knowing what it’s for I preferred not to touch it
The RAM is seen at 4800.

At 4800 they are working fine but I am tempted to return the 32GB. I would rather have 32GB at 6000 than 64GB at 4800.

Yeah…but even better is 16GB at 8000 or even even better 8GB at 12000. And the ultimate challenge is 4GB at 20000 with LN2

@SGS hasn’t kicked me out of the forum yet as the discussion is turning into a massacre… sorry but that wasn’t my intention 
In all this I would like to point out that I haven’t reinstalled any operating system yet. I decided to return 32GB of RAM and continue testing with “only” 32GB.

So, after various benches and “normal” use (gaming, browsing, ffmpeg conversion, memtest86+, etc) I didn’t notice any major problems, either Linux or Windows side. So I’d say the hardware upgrade without reinstallation went well.
If anyone has any questions or tests about this, just ask!
(I hope this thread serves as a bit of a reference)

ok, with broken hardware
…grats… 
I also have a job and a family…
Basically I think I should close the thread. Even if I digressed, I hope it can be of help to someone who has doubts.
Thanks to the staff for their patience
