    I'm trying to help a friend upgrade his iMac's memory. It is confusing to figure out which memory stick for which iMac.

    This is his Hardware overview
    Model Name: iMac
    Model Identifier: iMac5,1
Processor Name: Intel Core 2 Duo
    Processor Speed: 2.16 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2 

    L2 Cache: 4 MB
    Memory: 2 GB (currently 1 GB 2 halfs)
    Bus Speed: 667 MHz
    Boot ROM Version: IM51.0090.B09 SMC Version (system): 1.9f4

    I think the correct memory is PC5300 DDR2 667MHz 200 Pin, but since I don't have hands on the computer to simply check the old memory sticks, I need to be sure before I order for him.

    As always, I am grateful for help I often receive one MacRumors.

    It is PC2-5300. Uses the same memory of the MacBooks from that generation. So make sure you are getting the smaller iMac sticks.

    Yes, you are correct about the memory specs.
    200-pin PC2-5300 (667MHz) DDR2 SO-DIMM
