1, 2 and 3000 series Ryzen do have problem with both IMC channels are used by 4 sticks of RAM, Generally 3200MHz i best frequency for that case as Cas and other latencies can be greatly reduced, in some cases that helps more than just frequency itself.
Some of the problem is that 3000 series Ryzen have IMC frequency limit 3200MHz over which it has to be overclocked. (Just IMC, not whole CPU).
Another limitation could be MB and it's BIOS, should check for BIOS version and see if any mentions memory improvement.
Great tools to use for manual settings:
