Hi, i have a intel core duo processor in my macbook and it can only be upgraded to 2gb ram, can i upgrade my logic board so that my computer can have more ram, i have the macbook 1,1 and im wondering if i can put the motherboard from a later model (still non unibody tho) in it, so upgrade it to a 2.4GHz Core 2 Duo that can support 4gb ram. Thanks
