Can my 2006 Macbook take 4 Gb of RAM even if it's not supposed to?

    I have the white Macbook from late 2006 (2 GHz Intel Core 2 Duo). In the specs it says "up to 2 Gb".

    Since there are 2x2 Gb chips out there, do you know if it's possible to put 4 Gb of RAM in the Macbook?

    What would actually prevent this? Is this a software or a hardware barrier?

    Any suggestion?

    Thanks a lot

    You can find specs on all Apple products, including maximum RAM:

    3-ish gb of RAM

    Hi, after looking into the same thing, it will take 2x2 and use around 3gb according to several sites and a local Mac reseller I spoke to.

    I was going to upgrade from 2gb to 4gb in my 2,1 Macbook, but decided the cost was not worth it (locally I have been quoted from $75-100 Can).

    Lion runs ok on my machine and since I will be buying a new one this year or next it doesn't seem worth it.

    You can put in 4 GB, 3.3GB is recognized. I did it a few months ago to upgrade from my original 1GB when things were really starting to get sluggish.

    I think that's due to the limitations of 32-bit cpus.

    So unfortunately, you'll be paying for 4 GB and can only use 75% of it or so.

    It's a chipset limitation.

    Hi everyone
    Thanks for your responses. So what i can do is use my 1 gig chip along with a 2 gb chip, so it will be close to the maximum without having to buy another 2 gb chip.

    Thanks again

    I have a black late 2006 Macbook and just installed 2x2GB G.Skill ram (upgrade from 2x1GB Samsung).

    To my surprise, when I go to "About This Mac" it states that it is recognizing the full 4GB of ram. Going to system information further confirms this.

    I have read that the late 2006 MacBooks only recognize 3.3GB, but do they display as 4GB or 3.3GB?

    How can I test whether my computer is actually running with 4GB of ram or not?

    EDIT: Used iStatPro to look at my memory stats and they added up to ~3.3GB.
