    I have a 17" iMac Core Duo and trying to upgrade the memory. Everything I've read says that it will take 3gb memory, but when I insert a 2gb stick and a 1gb stick it won't boot. It boots fine with either stick, but not together. Here's the specs on the unit. Any suggestions?

    Model Name: iMac
    Model Identifier: iMac4,1
    Processor Name: Intel Core Duo
    Processor Speed: 1.83 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache: 2 MB
    Memory: 2 GB
    Bus Speed: 667 MHz
    Boot ROM Version: IM41.0055.B08
    SMC Version (system): 1.1f5

    It maxes out at 2 since it is a core duo and not core 2 duo.

    Return the 2GB and get another 1GB in that case (as stated in the post above).
