I own a MBP bought january 2010 with 4gb ram. Also own a white MB bought january 2010, and another white MB I will buy next weekend. I think they are still selling the same intel models. SO I thought maybe I could upgrade my MBP memory to 8, by buying a package of 2 x 4GB. Then use my 2 x 2GB sticks that I am replacing and put each one into the MBs, thus upgrading both of those to 3GB instead of the original 2. Is that possible? Are they the same size? Same type? Would they be recognized? I am a noob in all this and I have no idea which ones to buy, also from where, and whether my sticks from MBP will be compatible with the MBs. As far as installation, nothing Youtube cant fix. Help?!
