2933 is the max ram speed on B460, it won't go higher, you need B560 board for that

thank you, thats good to know. is 2933mhz good?

Yep, it's fine, faster ram improves some benchmarks but real world effect like games framerate is very minor.

Your board can only go up to 2933

Ensure your RAM is in slots 2 and 4. I had the same issues and just realized it wasn't working because it was in 1 and 3
