Strix B450-I +12V reading too low

[MrCommunistGen]

I just upgraded my Asus ROG Strix B450-I Gaming to its latest BIOS (2801) which contains the 1.0.0.3 ABBA AGESA version.  I don't remember if there was an issue with the voltage reading before the update, but there's clearly an issue now.  I also updated AIDA64 to v6.10.5200 recently. 

At idle, the +12V shows ~10.082V, and when the system is loaded it shows ~9.973V.  These values are clearly wrong as the system would not be stable with that low of an input voltage.  For what it is worth, my PSU is a Corsair SF600 Platinum.

 

Using a different tool I'm seeing 12.034V at idle and 11.968V under load.

 

I've attached a report of the system at idle.

AIDA64 uses the standard Asus WMI ACPI interface that has a known issue in a few BIOS versions on AM4 motherboards.  You need to wait for Asus to fix this bug in the BIOS of your motherboard.

Thanks for the update! 

 

I'll see if I can find a way to report the bug to ASUS.
