    Hi,

    iMac 2011 21,5 4GB RAM.

    I added 2 4GB RAM banks in DIMM1 slots.
    Now I have totally 12 GB.
    The system recognized them and memtest passed successfully.

    Anyway System Profiler shows for those new RAMs this:
    Dimensioni: 4 GB
    Tipo: DDR3
    Velocità: 1333 MHz
    Stato: OK
    Produttore: 0x0000
    Codice prodotto: 0x000000000000000000000000000000000000
    Numero di serie: 0x00000000
    It is in italian, but I hope you can understand the fields.

    Do you know why and if it is correct that profiler shows zeros in the last 3 fields?
    Are the memory performances/functionalities affected in some way, according you?

    Thanks in advance,
    Dave.

    There's nothing to worry about there. The two items are part and serial numbers. Apparently the manufacturer omitted them.
