Right, so i just recently noticed in my BIOS that my ram only runs at 2133 mhz when the speed is suppose advertised on the box is 2667 mhz. I tried to put on the XMP profile but, with no luck. After this i remeber that i havent really updated my BIOS in a million years so, i installed the latest BIOS update for my motherboard but again, with no luck. Whenever i put on the XMP profile and hit save and boot, it just black screens me and, i have to restart the PC to a screen that says the overclock failed.
