Max Watts of Power mode

Hi ,

I’m using Orin NX 16GB and JP5.1.1 and set power mode to 15W
In the nvpmodel.conf, there are just 4 cpus online and 4 cpus offline. But there are all 8 cpus online in Jetson Power GUI.

And if we burn in test the system, the power will over 15W.
Is the “15W” just a name of power mode? It’s not the max power limitation of the power mode?

Our team would like to get more information to clarify the problem, could you share the result of following commands:

  1. sudo nvpmodel -m 2 (reboot the system if needed)
  2. sudo jetson_clocks –show
  3. sudo systemctl status nvpmodel

This situation was happened twice yesterday.
But I can’t duplicate it now.
I will update if we have this problem again.

And the power mode name isn’t the limitation?
Can we set the maximum power limitation?

Ideally when you select the 15W mode, module power is expected to be less than 15W with a typical workload.
Did you run heavy stress on multiple engines (CPU, GPU, DLA, PVA, DEC, ENC, ISP…etc) concurrently?
What test case/application you ran?

Yes, we run stress test, CPU, GPU and Memory.
I run the cuda matrixMulCUBLAS sample app then the power is over 15W.
