so i had a problem with my z97 fatality killer ram issues i recievved the motherboard used with 4x2 gb ram. so i used 4x4 of my own ddr3 ram sticks andf its wouldnt boot which lead me to the conclusion my A1 and A2 ram slots r brokenis it possible because my ram is 2000mhz and the ram that wa sin it where 1333 mhz could this be why 2 just stopped working???
