I have been running an R5 1600 on an Asrock X370 killer SLI/Ac with 4x4gb 2400 Ballistix sport Ram for a couple of years now and decided to get a 3600.
I flashed the latest bios and installed the 3600 but it will only post with 1 stick of ram. Ive tried all 4 sticks in all 4 slots, all the sticks/slots work as long as there is only 1 in at a time. Ive cleared cmos a bunch of times and still nothing.
the fans will run and for a few seconds, then everything shuts off and restarts.
