Hey, Just wondering if anyone could give me a hand. I have a 2012 Macbook pro and I've just ordered a 2015 retina model. What I'm wondering is can I take the 16gb of DDR3 Ram from my 2012 model and swap it with the 8gb of LPDDR3 Ram in the 2015 model. My plan was to switch the RAM of both macbooks and sell the old one on. The question is... are the compatible with each other? Any help would be much appreciated.
