Do you have the newest BIOS flashed ?
If not I would do that:

Also is your exact model RAM kit listed here:
https://www.gskill.com/configurator?page=3&cls=1529635169&adSearch2=Tested_Speed§4000MHz,&manufacturer=1524725352&chipset=1539225224&model=1539225615

If not you may need to run it at a lower speed.

Also make sure the RAM is installed in the slots recommended (A2 and B2) on page 1-5 of your Manual:
