Question B450M DS3H WIFI bios question

Hi SweftyKnife (y) and Welcome to the Forum :)

If your system is performing OK then there is no need to update Bios as there is a risk however both would work.
F64a is the latest version for Ryzen 7 5800X3D to upgrade AGESA.
Check out F63 as that would be the best update for you. (support for Windows11)
