For owners of 800 series motherboards, with the latest bios with agesa 1.3.0.0, does mixed refresh mode work for you?

On my B850M Mortar even when explicitly setting it from the bios, Ryzen Master and ZenTimings show the "Normal" refresh mode, in fact trfc2 and trfcsb can also be set to the minimum allowed without impacting boot/stability.
