GIGABYTE B550M DS3H AM4 Motherboard + 32GB G.Skill AEGIS RAM @Newegg $130
It's a modern motherboard with modern bios software capable of doing amazing things with a Ryzen chip. Look up infinity fabric. It's some insane stuff
Paired with a good amount of decent budget ram. There's only a few factories that manufactures this type of ram so the name means very little. It call comes from the same factories
What AMD's IF tech does is allows your gpu to access the pool of ram memory quickly as if it was its own. It might be another gimmick but I've been using it for 3 years with this same ram and love it.
Look here for timing tips: https://imgur.com/6ZSDax7 What you want is absolute latency of 10. Anything lower and most of us won't see any returns
As you see there's a number of combinations that get to 10 or lower. In your bios this will be easy to test until you're happy with the speed. The speed listed on the product is just a factory setting they're confident of. Going over may void warrantee etc
