you may or may not be able to OC your CPUs memory controller that far, you may have to drop to 2133mhz which is all your motherboard technically accepts. Try this first. Enter you timings and voltage in bios manually according to you ram's settings. If that does not work try dropping speed down to 2133mhz....you should also be able to drop the T (cmd rate) from 2 to 1 at similar timings to slightly lower timings then you ram is rated for at 2400mhz. LMK if that works also what is the exact make and model of your ram?

Those AMD FX chips do not like going above 1866. Even that can be a problem. Usually I just set it to 1600 and leave it alone to avoid crashes.

all ideas sound good. ill start at 1600mhz and work my way up testing for stability
