Hi, I have a Macbook Pro 17" that came with 1Gb of RAM (1 stick; upper slot was empty). I have now ordered a second 1Gb module to put into the upper slot, for a total of 2Gb. The module was guaranteed to fit the Macbook Pro, and looks exactly like the one that came pre-installed from Apple. DDR II 667, 200 PIN, looks just right. The problem is that when I try sliding it into its slot at the 25-degree angle as specified on Apple's website, I feel incredible resistance, and even if I use all my strength, it's not moving into the slot at all. I have it in the right way, not upside down or anything, and simply don't understand what's wrong. Am I trying it at the wrong angle? Is it possible that I (a 95lb woman) am simply not strong enough to do this? Could the module have inexact exterior measurements that just won't fit? Has anyone else had issues like that? My feeling is that it's not the gold pins that don't fit (I'm not even getting that far where they would connect), but that it's the outer plastic shape of the thing. Has anyone had similar issues, and does anyone know a solution? My main question is: Should I try brute force/how much physical strength/force should I apply without damaging the existing memory underneath??? Please share your thoughts.
