False 12V voltage reading after BIOS update

Hi!

After upgrading my motherboards BIOS (Asus Prime X470-Pro) 12V shows only 10.1-10.2V. In the BIOS itself the 12V rail shows normal voltages, around 12-12.1V. It's not just HWiNFO that shows a much lower value, other softwares also has this problem. Could it be corrected some way? Thanks in advance!

Edit: log attached.

Thanks, this is a BIOS bug. I will notify ASUS about this so that they fix it.

New BIOS update arrived (5204) and the issue is fixed! :)
I'm glad that Asus kept their promises and fixed this bug. I also hope that their WMI implementation is also fixed, so no more randomly stopping fans (or going max RPM) will happen.

Thank you for your help Martin! :cool:

With the new BIOS 5216 WMI seems to be fixed now. Running all kind of monitoring software to test it in the past days, and no problems so far.
