How are you adjusting the timings? All of the adjustments on my bios are locked down with the exception of speed selection and xfr on or off. I have not been able to get the machine stable past 2400 mhz with bios. I have played with Command Center and Ryzen Master and been able to get CPUID to verify speeds of 2667 but all timings adjustments are locked down. Also, when i use the "wmic memorychip get speed" command it still says 1067 no matter where i have made adjustments. What is going on with memory on this motherboard?.
