I took a look at https://gmplib.org/gmp-zen5. It looks like a HW failure to me. It 
could be the cooling system, the motherboard, or even the CPU design itself. If you 
are concerned about the gmp tests, then skip them. However there was this statement:

Neither of the 9950X CPUs died immediately, instead they died the exact same way 
after a couple of months at high load. This seems to suggest a gradual but 
predictable degradation.
