Your current ram type is ddr3-1333. Any ram that matches this should go well with the system. I have taken some old ram from my old laptop that uses the same type of ram into my new laptop and found no problems. If buying, be sure you enter in LAPTOP Ram/memory or filter it in, whatever it is. Otherwise, the site assumes it’s desktop ram. About the cpu thing, you would practically have to open up the entire system to get to it, so I believe if you are comfortable with it, go for it.
