Hi, I built my first setup but I kinda skipped a little research when I installed the ram, I bought two 8gb G.Skill Trident Z ddr4-3000 but my mother board (msi mortar artic H270m) only goes up to 2133. It boots well with one stick of ram but it won't boot if I add both sticks. Is there a way I can add the second ram stick? I assume I have to do some things in my bios but I just can't figure it out.
