Mobo will not post with two sticks. LED error lights say something is wrong with the ram. I've updated the bios both sticks will boot if its just one of them. I got the memory profile set as well. Nothing seems to work

New setup? New ram? 2 modules worked before?

New Ram, I upgraded from a single stick of ddr4 8 gig. Both sticks work fine when plugin by themselves

Memory modules sold as Single Modules have no guarantee to work in any configuration other than as a Single Module.

I know I was using a single memory stick beforehand. I got a Gskill Trident 2x8 16gig memory kit to upgrade
