This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem.

and after that, system reboot, but no memory dump.

Hi @QiuHaiqing,

Processor performance can be affected by clock speed, cache size and the number of cores the processor has.

Use some laptop stand or something like that to give more room for airflow. My laptop also had same issue due to overheating. Once I used a laptop stand this issue resolved.
