Will this RAM work on my Macbook?

What is your MacBook? It should work if your MacBook supports DDR2 but I can't be sure

You need PC5300 DDR2 667MHz 200 Pin SO-DIMM Modules, as you obviously have a 2006-2008 MacBook.

To find out, do the following to find out the Model Identifier and go to EveryMac see what Mac you have.



As you most probably have two 512MB RAM sticks, you will only have 2.5GB RAM after the purchase of one 2GB stick. Look here for more information.

could you use pc6400 ram in that mac? i found a 2gb stick for cheap. i am the poor fellow whose memory slot failed. only have 1 memory slot working now. sigh. i have a single 1gb stick. 2x512 sitting in desk also.
