jetson orin nx 16G，When I use MAXN mode, the temperature of each chip does not exceed 70 ℃, but the system prompts overheating and the video shows stuttering and screen flickering.What went wrong？
Hi kensery,
Are you using the devkit or custom board for Orin NX?
What’s the Jetpack version in use?
Please share the result of the following command and full serial console log for further check.
# grep "" /sys/class/hwmon/hwmon*/oc*
Hi，Kevin
Thank you for your reply，I use the custom board for Orin NX ，enter the command and display this。
I think there may be a problem with NVDEC，it can‘t change，always 115MHz。NVENC can change。
How to see the full serial console log？
For the devkit, please refer to the following instruction.
Jetson Nano & NX Style - Serial Debug Console - JetsonHacks
For the custom carrier board, please find the find the similar pin on your board if the board is designed by you. Or you can request your vendor for the steps.
It seems you hit OC event for all OC1(under voltage), OC2(average power), OC3(instant power).
What’s the power supply you are using?
Are you running any application to cause OC event?
I would suggest you creating custom power mode instead of using MAXN to prevent hitting OC throttling issue.
From your previous result, it seems there’re many OC events.
But it seems good now.
Have you rebooted the board and check its count before running your application?
If so, please run your application and check if there’s any oc*_event_cnt
20V/4.5A (90W) power supply should be good as MAXN_SUPER at 40W for Jetson Orin NX requires minimum 8.0V to the VDD_IN.
You could try using power supply which is at the lower end of the operating range for slightly better efficiency.
OK,thank you very much.
When I use the MAXN_SUPER ,VDD_IN should be 8V or 8A?The voltage seems to be 5V,I measured the devkit for ORIN NX is also 5V.
OK,thank you.
