I tried using Intel XMP to adjust my RAM speed (1333 in bios) to its correct speed (2400) but every time I do the computer shuts itself off and it won't boot afterwards. I'll have to clear/jump cmos or the computer won't start at all. And whenever it starts up, it gives me this "A2" error message before the bios screen. I've tried to set it manually too, unfortunately it doesn't work as well. My bios version is also up to date. Everything seems to work fine except for my RAM speed adjusting problems 
Everything is at default speed, no OC atm.
