My macbook was freezing when tapped on the bottom case and I figured out that it was a bad ram slot. Whenever there is a stick of ram in the slot closest to the keyboard, and pressure on the corner of the slots will cause the laptop to freeze. Well now I'm trying to figure out my options. My laptop has 4gb of ram in it now and I wanted to upgrade to 8gb. What options do I have for ram? I can't find a single stick of 8gb pc8500 to try out in the machine. Will faster ram work? Is fixing the slot possible?
