Nano cpu clock rate drop when heavy loading

Hi forum,

when I run my program on nano devkit, the CPU usage is around 70-90%. After a few time, the clock rate will drop from 1.5 GHz to 1.1 GHz. I turn on the jetson_clock before running the program, but the clock rate still dropped.

Can anyone help me with this?


Could you check the thermal condition with tegrastats and see if any thermal throttling mechanism turned on and throttle the cpu freq?

There is a warning “system throttled due to CPU-therm”

Yes, then the cpu freq is dropped due to the thermal condition.

So the only thing I can do to avoid this situation is using a better heatsink?
