Different VCCIO and VCCSA values


New Member
Why would there be a .15 to .2 V difference in the values for VTT/VCCIO and VCCSA being reported by a) the motherboard (MSI Z390 Gaming Pro Carbon) and b) its NUC126 controller? (There's only one *actual* voltage for each of these, right?)


Looks like BIOS is reporting the latter (and higher) values, so I guess I'll go with those:

Yes, the latter ones are correct. Sorry for the confusion, I will fix this in next build.
