    Memory limitation on 2006 macbook
    Hey guys, I just received my first mac yesterday after using PC's for years. I know this may be a very old question but I am going to ask it anyway since I am new at this. I have a 2006 Macbook (2GHz Core 2 Duo, 160GB hd, 2GB ram, Snow leopard) and I would like to know is it possible to increase the ram to 4GB? I checked apples website and they say that it has a 2GB limitation but that could be old information. My laptop model is A1181 if that matters.

    Thanks for any feedback

    I believe this is your MacBook (A1181):

    MacBook "Core 2 Duo" 2.0 13" (White/06) Specs (Late 2006, MA700LL/A, A1181, MacBook2,1) @ EveryMac.com

    Yes it can be upgraded to 4 gigabyte of ram...but the computer will only recognize 3 gigabyte.

    And if you really want to why...then read this:

    Why are the MacBook Pro "Core 2 Duo" models limited to 3 GB of memory? If I install dual 2 GB modules, why won't I be able to use 4 GB of RAM? @ EveryMac.com

    Hope this helps,

    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
    Yes indeed. If it is the "Core 2 Duo", you can put in 4GB, but it can only use 3GB (hardware limitation). The 4GB is said to maintain the dual channel capability of the machine. Whether it does or not, I dunno, but I did put 4GB in my MBPro - same vintage.

    The previous model "Core Duo" limits out at 2GB
    I cannot be held responsible for the things that come out of my mouth.
