Ryzen 3 2200G Showing 256 Celsius

[Ryan Davis]

Ryzen 3 2200G showing a core temp of 256 Celcius while running World Community Grid. Only one of the four cores shows this temperature and it quickly goes back down to 30-65 Celsius depending on the load.

I was wondering if this sounds like a legitimate heat issue, a sensor issue, or a software issue?

It has done this while overclocked at 3.7 Ghz and at the stock 3.5 Ghz. Using an ASUS B350 motherboard and stock AMD CPU cooler.

It's just a glitch. It would have actually melted had it done anything close to that
