I have an MSI GT70 Dominator with 1 x 8GB stick of ram (SK Hynix 8GB 2Rx8 PC3L-12800S-11-13-F3). I am trying to add a second 8GB stick (Corsair CMSX8GX3M1A1600C10). Does it matter what slot I put the second stick into (there are four slots, currently three available), and do I need to change any bios settings, etc.? Thanks in advance!
