I'm looking to upgrade my RAM on my build. I currently only have 2GB of RAM and am looking to get at least 4GB more. My question is, what type of ram do I have to get? I currently have Mushkin 240-Pin DDR3 1333 (PC3 10666). I know I need to get more 240-pin DDR3 RAM but I am unsure of the rest. What do you guys suggest I get for RAM and what type to I need?
