I think you mean this post here:

Well, maybe the hysteresis temperature of Ryzen is not 75°C but rather 50°C,
meaning as soon as the CPU reaches (IMHO rather low) 50°C it starts becoming
susceptible to data corruption. That would explain the behaviour here on my
system.
One guy here "tosilva" suspects that there is a signal integrity issue:

that could possibly be fixed by raising voltages; what voltages excactly he
doesn't tell - so I assume every voltage. And by what amount - no idea.
That's what I'm trying right now, raising every voltage by 100mV:
CPU Voltage: 1.18750 -> 1.28750
VPPM: 2.550 -> 2.650
2.50V Voltage: 2.520 -> 2.620
DRAM Voltage: 1.210 -> 1.310
+1.8 Voltage: 1.820 -> 1.920
VDDP: 0.950 -> 1.050
1.05V Voltage: 1.072 -> 1.072 (can only be raised several mV, so I left it
AUTO)
