Hardware How are ssd ic numbered. Which is 1'st etc.

[matrixmm]

Hi, I'm trying to deal with a cyclic error: CE-108255-1. I replaced CXD90062GG but it didn't change anything. Now I'm trying to replace individual K9BKGD8J1A. Can someone tell me how they are numbered? e.g. which one is 1'st and which one is 6'th?
any help will be appreciated

On the PS5s with six ssd ics only three are replaceable. The two with the same orientation on the ssd controller ic side and on the back side of the ssc controller the single ssd ic.
The other three ssd ics form a drive, which contains not recoverable data. If this ssd ics are replaced, the PS5 is dead.

did you fix this problem? I have a console with same problem.

Do you know if they can be swapped ? I mean if 1,2 and 3 are the ones that can not be replaced, can you desolder 1 and 3 and solder ic 3 on socket 1 and ic 1 on socket 3? Idk how ps5 handles usage of each memory chip but supposing 1 is the main chip beign used on boot and now is somehow faulty swapping could making functional again after reinstalling system software

Anybody with solution of this? Somebody to replace the RAM chip of the SSD controller? Any success?

Ram chip of the ssd controller can be replaced , what can not are main block ssd ics

The DDR4 RAM chip over the SSD controller and the controller itself can be swapped. From the SSD NANDs three of the six can be swapped. The red marked ones have unique data stored which cannot be restored atm.

Do you know if there is someone developing something to be able to dump/restore those nand chips ?

Hi, what about PS5 slim, there are four if I recall, which are swappable and which are not ? Thanks
