Error Sensor VRM bug 127°C

[jefrainhv]

I just bought a B450 GAMING PLUS MAX, at first everything fine, after ordinary use after 2 weeks, I started with problems because in the sensors there always remains a sensor that marks 127 ° C on the VRM sensor, but it shows no changes even putting a 20-inch fan on top of the motherboard.

The real problem is that thanks to this temperature data, Thermal Trottling enters my processor and it lowers its frequency to 0.5 Ghz and makes it almost impossible to operate the equipment, I have to disable the thermal throttling through the windows registry but the error It is there, since sometimes if this works from the windows registry, other times it does not

It is strange as if it remains "stuck" and I suppose it is a bug, I have touched the VRM heatsinks with my finger and compared with the Chipset heatsink and the latter is hotter (PCH = 40 ° - 50 °)
according to HWMONITOR readings the sensor is always 127 ° C
in the HWINFO the temperature is sometimes shown and sometimes not: o

in the HW MONITOR of the same BIOS the information coincides with HWMONITOR (127 ° C) in the VRMs but as I said before
It doesn't seem to be an overheating problem because no overclock has been done

motherboard: B450 GAMING PLUS MAX
processor: Ryzen 5 3600

I attach images with the sensors and the normal temperatures in all the other sensors
average temperature of the area 35 ° C

I'm not sure why that sensor is showing 127c but i would start the motherboard RMA process immediately! Good luck with the RMA process i hope it goes smooth and fast for you!

Could be that hwinfo is reading the sensors incorrectly. Notice that vddp is shown as 0.

Edit.
Nvm, just read full post. RMA the board, something must be faulty if it's throttling that way.

Most of these board don't actually have VRM sensors. 127 happens to be the maxim 8 bit singed value, that's why it's stuck there, there is no physical sensor to feed data to that register.

There is probably something else wrong.

bunk sensor is not related to the throttling issue, that is a bios config issue judging by hwinfo in your screenshot it looks like there is some vendor meddling with the pbo config and you are hitting the configured power or thermal limits

reset the bios settings to the default and verify that PBO is set to its default settings

Bunk sensor readings like this are super common
