So I built my PC a week back, and have recently been playing every game in Ultra, but I got Battlefield 4 Yesterday and have been playing it quite a bit, but I have encountered alot of stuttering and a few crashes. Now this could because I am only using 4gb of ram. So I am going to be doing a Upgrade but with a different make I have one 4gb Kingston and 4gb Corsair both witch are DDR3 and 1600mhz. Now if I just place in my new Corsair ram into its slot then boot up my pc will it automatically start working or will have to do something to make it work??
