I'd like to upgrade the memory of a 15" Macbook Pro. It came with 4GB out of the box, but I don't know if it came as 1x4GB or 2x2GB.

Is there a way to know that, before unscrewing the computer?

Open the Apple menu, select About This Mac. Then click on More Info… and select the Memory tab.

@Daniel Thanks :) –  Oliver Salzburg Feb 3 '12 at 19:49

It will most likely be 2 slots. Double check your specs depending on model year. Most, if not all, are coming with 2x2GB

 4GB (two 2GB SO-DIMMs) of 1333MHz DDR3 memory;
 two SO-DIMM slots support up to 8GB

Edit - looks like all recent 15" have 2 slots. I just upgraded my early 2011 and it had two, make sure you read the directions before you upgrade. You'll need a #00 head screwdriver to get the bottom off, if you have a recent model macbook.

You were right, 2x2GB. I wanted to be sure however, Oliver's suggestion confirmed it. –  Benjamin Feb 3 '12 at 18:06
