Hey guys, i got a question: I got this MOTHERBOARD and one stick of this RAM. I also have evo840 and i really lack of ram when playing games. BF4 was given to play for free for a week, but i couldn't even start it cuz i didn't have enough ram. So would another the same 4gb stick of ram be enuogh or should i take this 8GB STICK instead? And also would 4gb and 8gb 1600mhz cl11 1.5v both crucial work together? Thanks for any help!
