fx 8320E handles MAX 2133 if done right, biggest factor is your motherboard and the speeds will run, and then there are your goals with the system, that mother board you asked about will go with 1600 and the fx 8320e at stock without overclock (unless you go to 4.0ghz). ut to be honest you will not see much if anything performance wise going 1600+ as most games out there are cpu or GPU dependant
