Hello! In a bit of impulsiveness, I have just acquired a Apple laptop: a lightly used Macbook 7.1 (released mid-2010 and discontinued, 2.4GHz Core 2 Duo). This is my first Apple computer! I want to upgrade just a wee bit to squeeze a bit more performance out of what is currently probably a mid to low end laptop. Two questions: 1) I know this Macbook takes 1066 MHz DDR memory. But I have two 2 GB sticks of 1333 MHz PC3-10600 DDR3 SODIMM. Can I put those in? Or do I have to get 1066 sticks? 2) I'd like to put a 7200 rpm hdd in it. Will there be any potential issues with heat? (I'm assuming a 7200rpm drive generates more heat than a 5400rpm drive.) Thanks!!!!
