    DDR RAM specs for the PowerMac G5

    - 184 pin DDR SDRAM DIMMs
    - unbuffered
    - 2.5V
    - 8 byte
    - non-parity
    - DDR333 (PC2700) for the 1.6GHz PowerMac G5
    - DDR400 (PC3200) for the 1.8 and 2GHz models of the PowerMac G5
    - DIMMs must be installed in "pairs" (the PowerMac G5 has a 64 bit
    memory bus ... so it takes two, 32 Mb DIMMs).
    - DIMM "pairs" must be matched in size / capacity (i.e. Can't match a
    512MB DIMM with a 256MB DIMM, both must be the same).
    - CL support = 2, 2.5, 3, 4 & 5. (Can have two different DIMM speeds
    (even among pairs), but performance will default to the slowest module
    per pair).
    In stock 1GB PC3200 Apple G5 Dimm, Ready for 8GBs, @ a great price!
