An OT hint to the author: I noticed that your RAM runs at 3800, that leads to a mismatch with the Infinity Fabrics' clock of 1800, i.e. increased latency.

There are two solutions to this:

Raise the FCLK (Fabric Clock) to 1900. This should be well tolerated by a Ryzen from the 5000 line.

Lower the RAM clock to 3600 and set sharp sub timings. This will take a little more time but this tool [0] will help. Runs on Windows though, i have an old partition around for stuff like this, dunno if a VM will do. RAM OC became a time consuming hobby for some people, the rabbit hole...
