The same here (Tomahawk B350 from MSI). With the "Typical current" option in BIOS the voltage has a minimum of 0.82V (that's what sensors report). If I change the setting to "Auto" or "Low current" it goes down to 0.4-0.5V.
With "Typical" my system is stable, with "Auto" it freezes, usually during the night. I haven't tried "Low" yet. Maybe next week.
