I am running a I7 6700k, a Z170AR asus Board and 32gigs of dominator platinum 3000mhz ram but it is only running at 2133mhz. When I go into the bios and change it to xmp settings so it will go to 3000mhz, when I save and exit my computer does not restart, it stays on and the screen goes black. It only restarts from the normal settings... PLEASE HELP!!!!!
