I recently upgraded my MBP to 8gb of RAM (totally worth it) but now I have these two 2gb sticks of DDR3 laptop RAM that I don’t have a use for. I tried to give them to friends with Macs but theirs are 2+ years old and take DDR2 RAM which isn’t compatible.
So if you have a unibody Macbook or Macbook Pro, this upgrade will work for you. Plus it’s free. You just have to pick it up from my house in this South of Chengdu.
Here’s a photo. There are two 2gb chips which combine to equal 4gb total and installation takes about two minutes.
