    Default How much RAM for my MacBook?

    hi,
    i recently bought a macbook off of craigslist and upgraded the RAM to what i thought would be an OK 4gigs.

    After tooling around the internet and passing by Crucials website they state my macbook can only handle 2gigs.

    here's my specs;

    Model Name: MacBook
    Model Identifier: MacBook2,1
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.16 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache: 4 MB
    Memory: 4 GB
    Bus Speed: 667 MHz
    Boot ROM Version: MB21.00A5.B07
    SMC Version: 1.17f0
    Serial Number: W8718V72YA3
    Sudden Motion Sensor:
    State: Enabled

    the macbook see's all 4gig but my question is;

    Is it able to use all 4gig?

    any solid input would be great.

    thanks,

    hondo

    According to my lists that model should only be able to see and index 3 GB of memory. If you have it showing 4, good deal.

    Arrow 3GB vs 4GB subtle

    OWC said in their initial investigation that the Core2 Duo MacBook can use only 3 GB for the MacOS, but a 4 GB configuration allows the shared video RAM to be interleaved for absolute maximum performance.

    I have a mere Core Duo (initial MacBook black config) and only 2 GB memory is recognized. The machine won't even boot if more than 2 GB hardware RAM is installed.

    If you see 4 GB available to applications, that's something I've never heard of before in a MacBook.

    How low can we go, quoting OWC about RAM of all things.

    Yeah, I'm sure they don't mind selling that extra 2GB stick to "optimize" the on board video. Seems buying an extra Gig of RAM to feed an integrated 64M video chip is overkill. Assuming the video chip can actually use RAM the OS does not address.

    No doubt it would be optimized though with all 3GB available for software and having two matched sticks.....if it works they way they say.

    (That sounds like there's some resentment or hesitation about quoting OWC?)

    I'll quote them as long as they're accurate and polite, especially when that information is not available anywhere else. I'm the kind of person to whom that extra 10% performance from interleaved integrated graphics RAM is significant. YMMV.
