Hello, we are currently using the NVIDIA Agx Jetson Orin 32G module with a power mode of MAXN. We have been running a program for testing and found that the CPU frequency is stable at 1728MHz, The GPU frequency is stable at 612MHz, especially when the program GPU usage is basically 100%, the frequency is still 612MHz. Through temperature detection, it was found that it is not a high temperature frequency reduction. What is the possibility?

Dear @liuyayun1991,
Moved topic to Jetson AGX Orin forum (Jetson AGX Orin - NVIDIA Developer Forums) to support
Hi liuyayun1991,
Are you using the devkit or custom board for AGX Orin?
What’s your Jetpack version in use?
What’s the program you are running? Could you share it for us to verify it locally?
Jetpack version 5.1.3，The running program is based on the detection of the BEVDET model
thanks，Jetpack version 5.1.3，The running program is based on the detection of the BEVDET model
We are using the Jetson Agx Orin core module, the carrier board is designed by ourselves, and the software is based on the Bevdet model application. We apologize for the inconvenience of providing it
May I ask if the orin core module can set the upper limit frequency for locking? If possible, how can I check? Thank you
Hi Kevin
I’m @liuyayun1991 ‘s colleague.let me add some about the phenomenon that we have found.
- First, we see that Orin’s CPU and GPU clock speeds in MAXN power mode are smaller than the nominal values, so we use ‘jetson_clock – show’ to check and confirm that there is indeed a CPU/GPU clock mismatch. We also see that there is no print power mode parameter at the bottom of the print message.

2.Then we checked the other power consumption modes and found that the main frequency at this time was the same as the 30W mode, but the power consumption mode displayed in the upper right corner of the screen was still MAXN mode.
3.In our follow-up attempts, we can’t reproduce the above phenomenon, but we found another phenomenon, when switching from MAXN to 50W mode, it usually prompts that it needs to be restarted, when we select OK, the device will not restart, at this time, the main frequency has been switched to 50W mode, but through jtop and the display in the upper left corner of the screen are still the original MAXN mode, which causes the actual performance to not match the displayed power mode. Do you know this question? Is there any way to fix it?

Hi liuyayun1991 and 2282753676,
It seems you are using custom carrier board for AGX Orin with Jetpack 5.1(L4T R35.2.1).
Could you update to the latest R35.5.0 to verify?
In addition, do you have the devkit having the same issue? Or it is specific to your custom board?
To use the max CPU/GPU frequency, you can run the following command:
$ sudo jetson_clocks
