I'm having an issue with the reported RAM Voltage on my Z390 Taichi Ultimate.

I've set my RAM voltage to 1.375V yet I'm getting 1.408V reported in HWiNFO64 and A-Tuning.

After clearing CMOS and booting with SPD defaults (1.2v). I'm still seeing an noticeable offset to the intended voltage.

UEFI = 1.2v
Reported = 1.218v

UEFI = 1.375v
Reported = 1.408v

Which should be trusted and any idea what's causing this?

UEFI is on v1.80
