Thanks Sr...,
Did you install AMD CCC or did you do a custom install of CAT 12.11 Beta 4 without CCC?
You have filled all of your memory slots. This may require you to raise your Vcore, VDIMMs and / or Vtt to stabilize your 4.5GHz OC under stress. This post is for a 980x but its content may still be helpfull to you http://www.tomshardware.com/forum/27...58so2#t1975337 Is your system stable at a DDR3 1800 setting?
Good luck,
