The memory overclocks extremely well in this mobo, there doesnt appear to be a problem getting power to it. Its only 3000MHz C15 yet I had it running at 3840MHz C17. There is considerable headroom at the stock 1.2V 2133MHz to clock higher (without a voltage change), yet even this speed doesnt work. Its unfortunate I dont have any other DDR4 here. Some 4133MHz is in the post though. It worth noting, my system works great with my 1080ti. Its on 24/7 and has been since new, its super stable.
