    Hi Guys,

    My parents own an iMac 20" 2.0GHZ Core Duo (4,1), they bought some more memory, but the iMac can't seem to address more then 2GB memory

    Is there a firmware update that can allow more then 2GB? or are they stuck with that amount..

    What happens if I install more then the 2GB is the system boots up but screen is blank. When I have 2GB or less it boots up fine..

    Appreciate your feedback

    Thanks

    I'm pretty sure that model maxes out at 2 GB. Enter your model at crucial.com and they'll give you some details about your system, including the maximum amount of RAM it can handle.

    2GB is definitely the max. No firmware can change that, as it is only a 32-bit processor and the chipset is limited to 2GB

    yes 2 GB only, but you will only ever need more if you would run some programs which would need more ram if you run them on a professionel basis
    like for example if you would run for making a living from it AVID or Final Cut Pro ,or if your parents are heavy gamers ,but then the iMac would anyway be the wrong choice :rolleyes:
    under normal usage , you wont ever feel the need for more ram ,i thought about upgrading to 2 gb on my one in my signature , but so far i dont feel its necessary ,and would be wasted money , as everything runs with only 1GB even photoshop and final cut , ok i only use these programs to do up some holiday pics and movies , otherwise the iMac is mainly used for web surfing and emailing and itunes and watching movies


    if you really need more then just replace the internal HDD with a SSD,put the HDD then in a firewire enclosure for storing files and a backup partition sorted
