I POSTED THIS ALSO IN THE MEMORY FORUMS BUT I GOT NO REPLIES....

I just finished putting together my new pc:
motherboard - ASUS prime B450M-a/CSM
Memory - corsair vengeance lpx 3000Mhz 2x8GB DDR4
CPU - Ryzne 5 2600x

the default memory Mhz setting is @2133Mhz. I tired to boost it up to 3000mhz in two ways in the Asus bios "AI tweaker" menu:
1- By directly changing the memory frequency from "auto" to "DDR4-3000Mhz"
2- By choosing "D.O.C.P" as the profile then it changes the frequency to 3000Mhz

both ways ended up in a safe mode boot because the system would not post

WHAT AM I DOING WRONG?
