No, Ryzen will never support 3000 MHz RAM. It simply does not have that capability.
If your motherboard will get AGESA 1.0.0.6 update, then these are supported values above 2667 MHz : 133.33MT/s intervals (2667, 2933, 3067, 3200, 3333, 3466, 3600, 3733, 3866, 4000)
As of today only 5- 6 motherboards have got AGESA 1.0.0.6 update and they are betas.
