Two days ago it happened to me again, I was using ryzen master, on one monitor ryzen master stayed on, on the other there was some you tube video I was watching, suddenly ryzen master went crazy, nailed almost all values at max to red, and hwinfo reported cpu iod hotspot of 400c.Just checked other parameters carefully, all were fine, voltage parameters were normal, everything except CPU IOD HOTSPOT was ok.
Again, I am bitten by the worm of doubt whether it is a telemetry error, or whether the processor really sticks to this Asrock board when it is idle.
