Great news! I haven't been keeping up with BIOS updates on my CH6 Hero, since Asus apparently breaks something with every update. Fix one thing, another thing breaks. That RAM speed will really help Ryzen when you utilize all the cores.
Played a little with memory timings and not only can I get running at its rated 3000mhz but also on tighter timings 14 16 16 instead of 15 17 17.
Might see if I can get tighter on the timings but since I bought the wrong RAM I don't hold up much hope of any more improvements.
I should have done my research and bought WAM using samsung instead of the hynix stuff but hey ho
