Hello,
I am having a similar problem to Jetson Orin Dev Kit - System Throttled Due to Overcurrent.
I am running 2 AI applications (Deep learning networks)-
Platform : Jetson AGX ORIN development kit in MAXN power mode.
what can cause this?
Thank you,
Rinat
Could you dump the power GUI or tegrastats result when you run your application?
This means your application has hit the power limit of orin AGX. and it is not easy to hit this on Orin AGX devkit because the power limit on Orin AGX is quite high…
Are you sure this log includes the situation with OC warning triggered?
Just a reminder that we have a note in the document that maxN is just an experimental mode. You should not use it to test your production.
Hi,
Thank you,

Hi,
- Yes , I am sure. just recorder the log and the warning appeared
It could be instant power goes over the limit and as your poll time is 1 sec for each tegrastats result, it does not catch this alue.
- So what does it mean? You don’t recommend using MAXN mode? should i use “Mode 50W” instead? In 50W mode, will the system protect from over current situation?
You should choose a power mode which does not affect your usecase and in the meantime it does not hit over current situation. Some users even made their custom modes.
Ok. Just to clarify the last point - In MAXN mode there is no “over current” protection but in the other built-in power modes it is guaranteed?
No, it does not mean that.
The so-called “over current protection” is the system will throttle your cpu/gpu/emc and leads to performance drop. Even in max-N mode, this mechanism is still there. But if the system keeps doing throttling, your overall usecase performance may drop or got affected.
Using proper power mode is just limit the cpu/gpu/emc to a proper range and it may not hit overcurrent. We put a upper bound there.
