In this particular case, the compatibility between the RAM and the motherboard is determined by the motherboard, so I would suggest checking the supported RAM for your motherboard.
Also according to the processor supported RAM frequency is 1333 MHz, so any RAM higher than that will run at 1333 MHz .
I've this motherboard: Asus Striker II Extreme.
Velocity bus dati [MHz]
1600 MHz Max velocity bus 1600 MHz
Maybe the RAM were broken?
