Woops was thinking of wrong one processor, I dropped the ball on that one. The AMD website states it will go stable at 2933. My bad earlier. On what MB did you find it goes beyond that? My X470 won't let me POST even at 3000. :/

Do not go above 2666 mhz on the ram, that cpu is limited to 2667 mhz and is unlikely to successfully overclock higher. Although 2 x 8gig ram would prove a massive increase to your gaming experience with that build.
