Hey guys, i just got a nMP a few days ago and im still in the return frame. My question is: if i buy the 4GB mac pro stick apple sells here http://store.apple.com/us/memorymodel/ME_MACPRO_W13_RAM is it the same 4gb stick thats currently in my pro? I have the baseline 2013 model. I'd like the sticks to all be 100% the same, but i'm not so sure they send the same stick if purchased separate. Thanks!
