I am looking to upgrade the RAM on my 15.4" 2.4 MacBook Pro I just got. But the book says I have to use PC3-8500 DDR3 1066 MHz 200-PIN. I am most worried about the number of pins because I can only find 204-PIN RAM and not the 200-PIN RAM. Will 204-PIN RAM work? This is what I was looking at. Will it work? http://eshop.macsales.com/item/Other World Computing/8566DDR3S4GP/ Also Im not entirely sure what the whole unibody thing is. Ya Im a newb when it comes to that I guess. I just picked this thing up on Saturday so its the new MBP. So is it unibody or not?
