I am trying to build my first desktop system and have recently purchased an aus m5a99x evo r2.0 and corsair 2 x 8gb memory sticks 1600MHz CMZ16GX3M2A1600C10. From what I've read the sitcks should fit but they don't seem to and i don't want to force it and break something. Is there something I am not understanding? Thanks for the help!
