System throttled due to over-current?

zhg65671 · January 28, 2021, 9:54am

I just got a new Xavier NX and flashed the latest image from nvidia website. Next step, I cloned yolo, changed to mode 2 (15W 6 core), but then this error message popped up whenever I try to run yolo. Is that normal or have I got a bad board? I could understand the error if I am using a nano and powering thru usb, but I am using a NX which is powered by the DC barrel provided in the box. How could I went over-current with the default power brick in the box? Right now I can only run 10W modes. Any help would be appreciated, thanks.

I too have the same issue as described with new Xavier NX.
Any suggestions NVIDIA?

@zhg65671
Could you run the sudo tegrastatus and also check with others mode by nvpmodel?

I have the same issue as described with new Xavier NX too. and I use 10W MODE, this warning disappear. But I need use maximum performance. I use the original power adapter, witch is 19V 2.37A. I try to remove all usb device, it doesn’t work.

We see the same issue. In JetPack 4.4.1, putting the same stress on the system, we do not get the system throttling message. In JetPack 4.5, we get the message that the system is throttled. It seems as if in the new JetPack Version, throttling starts already at 10W even for the 15W mode. Tegrastats shows loads around 10-12 W.

Could you have detail step to us to reproduce the issue.

Thanks

We run jetson_clocks and then use the tool “stress”:

stress --cpu 6 --io 4 --vm 2 --vm-bytes 128M

Then we run the visionwork-sfm sample. After that we get the throttling message. Tegrastats shows:

All 15W modes exhibited the same issue. Here’s the tegrastatus

ShaneCCC · February 4, 2021, 7:47am

Hi,
Can’t repo it by using 19v 2.37A adapter.

List test steps:

Run on 15W 6core mode
Enable cpu stress:
$ stress --cpu 6 --io 4 --vm 2 --vm-bytes 128M
Run VisionWork samples:
nvx_demo_feature_tracker
nvx_demo_feature_tracker_nvxcu

Tegrastats:

Hi ShaneCCC,

From the tegrastats output, it seems that you don’t reach the critical range of the power, as VDD_IN is below 10W. Can you put more load on the system with other samples? I reached it by running “./nvx_sample_sfm”.

JerryChang · February 4, 2021, 8:54am

hello sevm89,

may I know what’s the actual use-case for putting CPU with extreme usage and running VisionWork?

sevm89 · February 4, 2021, 9:06am

Hi JerryChang,
We are just doing a temperature verification under heavy load to verify our thermal solution.
However, we think it is a bug of the new JetPack 4.5, totally independent of any use case. There should be no throttling when the power is below 15W and the temperatures are ok. Am I wrong?

JerryChang · February 5, 2021, 2:31am

hello sevm89,

just for confirmation,
did you had exactly same testing setup with JetPack-4.4.1 and not able to reproduce the issue?

sevm89 · February 5, 2021, 1:24pm

Yes, in JetPack 4.4.1, we never got such a message.

zhg65671 · February 8, 2021, 5:15am

Just want to update on this matter: I sent the original NX back and received a new one, but the same problem persists.

sevm89 · February 10, 2021, 1:26pm

Hi

Is there any update from NVidia?

mehmetdeniz · February 15, 2021, 6:46am

I got the same issue on deepstream. In previous version (JetPack 4.4.1), I did not encounter any warnings. I disabled notification as a workaround but there should be a solution

Freeman.ix · February 15, 2021, 9:02am

I can confirm similar issue, using JetPack 4.5, see my thread:

sevm89 · February 18, 2021, 8:51am

Can NVidia confirm this problem? Could you reproduce it?

norrarat.s · February 26, 2021, 1:21pm

I have the same issue. Running on jetpack 4.5 as well.
