I have a 2gb macbook pro and want to upgrade to 4gb. I've read other similar posts but i dont see one that addresses my question. My MBP comes with (2) 1gb sticks of RAM. If i want to upgrade to 4gb, does it matter if i get a single 2gb stick added on or should i get (2) 1gb sticks like the original setup. Does it matter? Not sure how many slots there are. Perhaps i should just get (2) 2gb and replace the old ones altogether.
You can add a single 2GB stick to one of your present 1GB sticks for a new total of 3 GB (one 1GB stick not used), but not a large gain from 2 to 3GB... If you want 4GB, you'll have to buy a new 4GB set (2x2GB sticks) and put the 2 1GB sticks away or sell them. Go to Newegg or Crucial or Kingston and you'll get what you need.
Thanks Noels, i will take your advice and get the 4gb kit (2 x 2GB).
As noted above, make sure that your MacBook Pro is actually capable of being upgraded to 4GB - not all are. In fact, it's only been the last 2 revisions that can go beyond 3GB. If you want to be sure, use the Memory Adviser at http://www.crucial.com.
