    Hi everyone, I have a MacBook from the summer 2007 upgrade cycle. I've read in the manual that this laptop takes up to 2 GB of RAM, with a 1 GB stick in each slot. I just ordered a 2 GB stick, thinking I'd pull out one of the 512 MB sticks and add in the 2 GB, making it 2.5 GB. I read on Canadaram.com that you can put in two 2 GB sticks of RAM, but the computer will only recognize 3 GB.

    My question is, which way is it? Will the the 2 GB work with my 512 MB, giving me 2.5 GB? Or should I cancel my order and order two 1 GB sticks bringing it to 2 GB total?

    Any advice would be appreciated.

    Don't cancel the order !

    2GB + 512MB will be fine. Some people say they have to be matched RAM chips but I am sure you will find that the machine will be much quicker with the 2.5GB in it - and quicker than going for 2 x 1GB.

    Apple recommend that you go a total of 2GB but your macbook is capable of 3.3GB.
