There are various "stress test" programs you can get if you Google
around. I expect these will produce the same symptoms.

I'd say this is evidence that you don't have sufficient cooling.

If things are installed correctly. For example, cheap thermal paste
between the CPU and heat sink can cause these symptoms.

Get more cooling. Maybe lower the clock speed (if possible). Run a less
efficient MD code!
