    Hi folks,
    I'd really appreciate if you could help me. I have an iMac with the following spec.
    Hardware Overview:

    Model Name: Mac
    Model Identifier: iMac5,2
    Processor Name: Intel Core 2 Duo
    Processor Speed: 1.83 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache (per processor): 2 MB
    Memory: 1 GB
    Bus Speed: 667 MHz
    Boot ROM Version: IM52.0090.B09
    SMC Version: 1.6f0

    It currently is running on 1 GB, I wanted to add a second GB in order to upgrade my OS to Snow Leopard version 10.6.3 and beyond. Previously all was going well with the iMac eg I could use Skype etc until my son upgraded the software on his iPhone 4.

    I phoned Apple, was advised the module I would require and also purchased the Snow leopard OS.

    I fitted the additional module of ram, but it still wont recognise it? I swopped the modules around, and it is recognising each module just not the pair. I got back on to Apple and they cant help me because they tell me I have one too many digits in the Serial no of my iMac, so they can't advise me further!!!

    It bugs me that I went to the extra expense of purchasing the memory directly from Apple, and now they won't assist me in upgrading the memory.

    Ant advice or assistance would be much appreciated.

    Many thanks

    You bought ram from apple? Well, I suppose you did buy an iMac in the first place.

    Post the details of both the sticks, I'd guess are they both run at clocks the mobo supports but they arent the same so cannot be used together.

    Even if they aren't the same they still should be able to both work just not in dual channel. That said I know nothing about macs.

    OP,

    maybe post your issue in the mac forum-I'm sure there are plenty of apple geniuses there;)

    I just removed both from the iMac and the detail is : MT8HTF12864HZ 667 HI 1GB1RX8 PC2-5300S-555-13-80

    I checked carefully and both are exactly the same
