Just in case anyone is wondering, I got 8GB of RAM to work on my Macbook 5,2 under

Snow Leopard 32-bit
Windows 7 x64


I Googled this extensively and hadn't found anyone else who was able to get this to work. So I thought I'd be the first to tell everyone.

    Hey Jesseeeeee & welcome to the forums.

    This is very interesting! What brand of RAM are you using?

    Please keep an eye on how your computer is performing & let us know if any issues arise. I'm quite curious!

    I just tried this with my 2009 2.13GHz board. I too get 8GB working. This is a macbook logic board that I have installed in an Apple G4 Cube enclosure. I'm currently running it with a 128GB SSD drive as my boot drive and an internal 500GB hybrid as a built in backup on the optical drive SATA connector. The internal Superdrive is connected via USB. Everything can be powered either the MagSafe or original MacBook battery which I also installed in the cube.

    Very snappy with 8GB of RAM!

    Has your battery been much worse since you installed this 8gb of ram, though? It must have been eating up your battery like crazy.

    Your success story motivated me to do the same to my early 2009 macbook. I just got the exact same memory today from and I'm glad to report that it works like a charm! The 8GB is detected and can be fully used. Woot, no more excessive paging! Now I can run two virtual machines, xcode, photoshop and two browsers seamlessly. Thanks for the post!

    Yea that's the one. You can probably get it cheaper on other sites if you look around. I've had this memory in my computer for a while now and I'm glad to say that it's been working like a charm. The battery life does drain faster if the full memory is being utilized, but it hasn't been too dramatic (30% decrease maybe). My battery is about to die anyways so I don't care. I'm curious to see the effects on a brand new one. Hope that helps anyone.

    Hi, I am very interested in upgrading my macbook to 8GB too, but I just have a question ...


    Have you tried to re-install/install snow leopard or lion with this memory?

    and don't you get occasionally any corrupted files, whether files/photos/videos/downloads etc?? ...


    I asked becuase I have tried to upgrade my memory before with other brands and I have had troubles, memory is recognized and the computer apparently works fine, memory passes all hardware tests... but in some tasks, in my case specifically when re-installing the OS or when working with files over 3GB (photos or videos) then files get corrupted and I get error messages....I know this is a memory issue because if I go back to the original memory then everything works fine.  So I am just curious to find out if you really haven't had any issue using this memory.

    I've had 8Gig in my 2.4G Intel Core 2 Duo Ali Unibody MacBook5.1 late 2008 running 10.7.2 for 6 months plus now without a single issue.

    Hi Gera,


    I haven't tried reinstalling the OS and I haven't upgraded to Lion yet. I don't think it would be an issue since I don't  get any corruption errors at all. I use vmware virtual machine and Xcode daily and they both take a substantial amount of memory. I haven't had any problems yet and it's been several months now. I would suggest giving crucial memory a try.

    Still working guys? It's a bit of an investment for some of us. It hasn't yet been a month yet, but can anyone report on any issues you may have had? I'd like to upgrade too. Thanks.
