This is quite weird as something in the system seems to be constantly disabling access to the VRMs.
Check the "Intel(R) Serial IO I2C Host Controller" devices in Device Manager whether they aren't perhaps disabled. Or alternatively try to uninstall their drivers.
After you disabled the "Allow the computer to turn off this device to save power" on those devices, can you please attach a new HWiNFO Debug File?
I would like to verify how it behaves in this case.
That seems to have resolved the problem with constant disabling of access to the VRMs and the readouts look much better now.
Unfortunately it still sometimes reads erratic data. Not sure why is that but at least there's some good progress.
