I have the M5A97 original model. The very first one. It is paired with the Fx8320 and cooled by a TX3evo. Now during winter when it gets to like 24 Degrees C, I overclock. I dont have manual settings. I just let the AI suite do the thing. It runs stable at around 4.1 if I remember correct. Ofcourse, the RAM mhz is reduced a little from 1600mhz. Im no expert overclocker, but what you want seems pretty reasonably achievable.
