    Doesn't make one bit of difference.

    As long as each module is DDR3 204-pin and not higher than 1600 MHz or 8 GB, you're fine.

    Do consider going for one 8 GB module to add to one of your existing 2 GB modules rather than swapping both out with 2 x 4 GB. In many cases, it will be cheaper - especially if you decide to upgrade to 16 GB later on - and you get 2 GB more.

    The difference is how the individual memory chips on modules are addressed and package. But to your computer it is a black box that provides memory of the correct size and speed. The bottom line is it does not matter as long as the specs are correct.

    Another thing to keep in mind is that Apple products are historically very finicky with which sticks of memory they like. Just make sure to search the Amazon reviews for the one you linked to and make sure that people are happily using it with the model you intend to use it with. Then you should be fine.
