[gentoo-user] [OT] BIOS Best settings (no o.c.) for ZEN 5 3600 / MSI Tomahawk max ?

Hi,

I am trying to figure out the best settings (performance wise) for a
AMD Ryzen 5 3600 with a MSI Tomahawk max motherboard.

I don't want to overclock -- tweaking the bios is for finding
the optimal setting in oposite to waste performance via sub-optimal
settings like not activateing XMP profile and running the RAM at
JEDEC speeds instead of what the vendor guaranties.

Unfortunately, there are quite a view settings to which I didn't 
find any explanation, for what they are good.

Any help is very appreciated! :)

Cheers,
Meino
