256 C....Ryzen only goes to 90 C....at 256 the chip would be fried.

My guess is that the temperature sensor has gone wonky...

It's pretty much an incorrectly read sensor.  Values like 127c or 256c should always be treated as suspicious, as they can be a sign of software reading the wrong memory address to get temperature from sensor, or other such issues.

 

127 = 0111 1111 in binary , it's the maximum you can store in one byte if the 8th bit is used for sign

256 = 0000 0001  0000 0000 in binary, another value that doesn't really make sense for temperatures ...

 

Use hwmonitor or aida64 to read the temperatures, see if those get it wrong as well.

 

btw. a Ryzen cpu would probably start to throttle (reduce its frequency) at around 95-100c and eventually shut down.  So 256c is not realistic.  It never was, since solder melts at around 217 degrees celsius, so the socket and components on the motherboard would de-solder themselves at such temperatures.
