    I've got an iMac G5 (isight) which I bought in Dec 05. I would like to upgrade another 1GB of RAM. The thing is that I can't tell the difference btw PC4200 and PC2-4200 533mhz RAM.


    Need some help here. Thanx!!

    iMac G5 (iSight) comes with a 512 MB DDR2 SDRAM module built into the logic board that can't be removed or replaced. It also has one additional RAM slot that can support up to 2 GB of memory (you can install a 512 MB, 1 GB, or 2 GB module in this slot). You must use a memory module (DIMM) that meets these criteria:

    PC2-4200
    unbuffered
    nonparity
    240-pin
    533 MHz
    DDR2 SDRAM
    DIMMs that have any of the following features are not supported in the iMac G5 (iSight):

    registered or buffered
    PLLs
    ECC
    parity
    EDO RAM
