if your RAM is sold as 3000 and that is its stock. set the BIOS to use the proper A-XMP AMD eXpanded Memory Profiles.
the memory controller is built into the CPU and the BIOS via the A-XMP will overclock that allowing the RAM to run at its stock speed of 3000 or beyond.
the Joint Electron Device Engineering Council (JEDEC) states that DDR4 run at 2666 and lower.
from the mobo specs page-
"1866/ 2133/ 2400/ 2667Mhz (by JEDEC)
For AMD Ryzen Gen3 (R5/R7/R9)
2667/2800/2933/3000/3066/3200/3466/3600/3733/3866/4000/4133 by A-XMP OC mode
For AMD Other CPU
2667/2800/2933/3000/3066/3200/3466 by A-XMP OC mode "

when you install the RAM (example 3000) it will show up as 2133 (JEDEC) and the system will run, until you go into the BIOS and tell it what speed and voltage your RAM needs at stock through the A-XMP settings, they should be ready to go. in my b450 board I opened the BIOS, went to the memory settings and told it to use 3000, rebooted and the RAM was running at its stock of 3000.
