I´ll found some usefull settings (THX to flusher1 from reddit) for people, who uses a MB´s from Asus. I´ll test this settings with my friends on my rig and the rig of my friends. A, B350-A, B350 - Plus, X370 and the ROG Crosshair VI Hero, with diffrent DDR4 Boundel (32GB - 64GB / Dual Channel). Dosen´t matter wich RAM we tested, they run with those settings on full SPD.
RAM we tested:
- Corsair Vegeance LPX 3000 (4x8GB / On B350-A)
- Corsair Vegeance LPX 3200 (4x8GB / On B350 Plus)
- G. Skill Trident Z RGB 3000 (4x8GB / On X370 Pro)
- ADATA XPG Dazzle LED Series (4x16GB / On ROG Crossair VI Hero).
Don´t use D.O.C.P and follow those settings. And be sure to use the latest Bios Version.
! Cave !

I hope this will help some, until you get a final Bios with propers SPD Supoort, without edditing.
