Review on Crucial PC3 12800 SODIMM 204 Pin Memory by Dennis Long

a number that doesn't match this one. As worrying as it may sound, the site's important FAQ indicates that that storage and distribution serial numbers may be different and you should instead look at the specs listed. Anyway, installation was surprisingly easy, it consists of simply unscrewing and removing the back panel, then removing the old RAM sticks and the new sticks to install, which even a non-technical person like me can do. I found Critic's video guide on how to replace RAM helpful as the guy points out some safety issues like static discharge and the number and placement of screws. After installing I noticed immediately a difference in the update Applications open much faster than before and parallel ls for Mac runs smoothly. I would highly recommend this update to other MacBook Pro users with 4GB or less of RAM.
