    Macbook 2,1 Mid July 2007 RAM Upgrade Question
    Hey guys, this is my first post here! I have a quick question. I currently have a Macbook 2,1 and it only has DDR2 2gb 667mhz of RAM. I am planning on putting 2x2gb RAM in it to get it up to 3.3GB of RAM. My question is would I have to be limited to only using 667mhz of RAM in my Macbook? A friend of mine has DDR2 2x2gb 1066mhz he's willing to let me use. Would it be safe for me to use that memory? Would the memory be compatible with my Macbook? Any info would be great! Thanks.

    Specs:
    Mac Mini Core i7 2012 | White 2009 MacBook 2 Ghz | 733 Mhz G4 Quicksilver
    You need the 667 memory

    And you will get the full 4 gig (the 3.3 gig you quoted in what happens when you install 4 gig on 32 bit Windows) even a Mac with a 32 bit operating system can see and use up to 32 gig of ram

    Correction - your mid 2007 macbook may indeed be limited to 3 gig

    Specs:
    15" MBP '06 2.33 C2D 4GB 10.7; 13" MBA '14 1.8 i7 8GB 10.11; 21" iMac '13 2.9 i5 8GB 10.11; 6S
    There's no 3.3 to it - that's Windows 32 speak.
    OS X in the '06 MBP and the '07 MB will only use 3 GB.
    The limitation has to do with the Intel chip in these machines.
    I own and am still using one of each of these 2 machines. They both have 2 x2 GB kits in them.
    Using a 2 x2 GB kit will maintain the dual channel capability of the machine.
    The system will recognize 4 GB are installed, but only 3 GB are available to be used.

    As to the memory your friend has, if it's 200 pin - you're getting them for free - I'd probably try it in a 6 yr old machine.
    It will either work or it won't. Not going to damage anything unless you damage something inserting them.
    If it does work, it's only going to run at 667 speed.
    I cannot be held responsible for the things that come out of my mouth.
    In the Windows world, most everything folks don't understand is called a virus.

    I can tell you it will not work. The machine is capable of running up to 667 but will accept some 800 and clock down to 667.
