Uart Error 80810001 (213C)

Hi everyone, I have a faulty PS5 in my hands: the string code is 213C. What exactly does it refer to?
I used to use Dony Tools GUI, but unfortunately my old desktop PC has died.
@stetofix, you might be the only person I know who could help me identify the problem.

SOLVED, the problem was in GDDR6 bank n°7, it was completely short-circuited. The strange thing is that after removing it and replacing it, I started getting 8080110E on banks 1, 2, 3, 4, 5, 6, and 8. I had to replace them all to fix it permanently.

I was wondering for next time: if I’m forced to replace all the modules and I have Micron chips, do I necessarily have to replace them with Micron, or can I replace them with Samsung or Hynix ones taken from a donor board?

Single replacement chip should match the others chips on the board.
Whole sets can be changed to another manufacturer (Samsung/SKHynix/Micron)
