Hello everyone, first of all, thanks to
@dosdude1 for the information provided. I bought a pair of memory chips from AliExpress for a MacBook Pro A2338 M1. The chips I received are H23B4T84K7AEQ, marked N00 and N100 respectively, each with 512GB.
I installed them in the position indicated by the seller, but they didn’t work. I get errors like 4014 or other types of errors. The memory is detected correctly with P15, so I think a proper dump might be missing, but the seller is not responding. Can anyone here help me?
update : I reinstalled the original memory chips in the Mac and it powers on without any issues. Thanks everyone.
