I'd get 2 x 4gb 1866 cl9 1.5V ram. Low profile to avoid clash with the cpu cooler eg GSkill Ares
offcouse id normaly do that but the thing is i just recently got the stick of ram for nothing an its gskill 1866 4gb an i wanna kno if it would be better to dc the 1866 to 1600 or oc the 1600 to 1866 its only temparary till i get a 32gb kit an 4gb is just awful lol
