Jetson Nano under full load is always cut off

I am using the Jetson Nano with Power Jack. But when the system (especially GPU) is under full load (Mode MAXN), it will be cut off within several minites.

Here is the temp and power supply – jtop

I have tried several Power Mode – /etc/nvpmodel.conf

Mode 1 is OK

< POWER_MODEL ID=3 NAME=25W >
CPU_ONLINE CORE_0 1
CPU_ONLINE CORE_1 1
CPU_ONLINE CORE_2 1
CPU_ONLINE CORE_3 0
CPU_A57 MIN_FREQ  0
CPU_A57 MAX_FREQ -1
GPU_POWER_CONTROL_ENABLE GPU_PWR_CNTL_EN on
GPU MIN_FREQ 0
GPU MAX_FREQ 640000000
GPU_POWER_CONTROL_DISABLE GPU_PWR_CNTL_DIS auto
EMC MAX_FREQ 0

Mode 2 is BAD

< POWER_MODEL ID=4 NAME=30W >
CPU_ONLINE CORE_0 1
CPU_ONLINE CORE_1 1
CPU_ONLINE CORE_2 1
CPU_ONLINE CORE_3 1
CPU_A57 MIN_FREQ  0
CPU_A57 MAX_FREQ -1
GPU_POWER_CONTROL_ENABLE GPU_PWR_CNTL_EN on
GPU MIN_FREQ 0
GPU MAX_FREQ 640000000
GPU_POWER_CONTROL_DISABLE GPU_PWR_CNTL_DIS auto
EMC MAX_FREQ 0

Mode 3 is BAD

< POWER_MODEL ID=5 NAME=30W >
CPU_ONLINE CORE_0 1
CPU_ONLINE CORE_1 1
CPU_ONLINE CORE_2 1
CPU_ONLINE CORE_3 0
CPU_A57 MIN_FREQ  0
CPU_A57 MAX_FREQ -1
GPU_POWER_CONTROL_ENABLE GPU_PWR_CNTL_EN on
GPU MIN_FREQ 0
GPU MAX_FREQ -1
GPU_POWER_CONTROL_DISABLE GPU_PWR_CNTL_DIS auto
EMC MAX_FREQ 0

Is there any way to fix the problem and improve the performance?

What adapter do you use?

Adapter

INPUT: AC100-240V 50/60Hz
OUTPUT: 5V-4A

what’s your Nano version? emmc version or sdcard version?

Jetson Nano Developer Kit

SDcard: 32GB U1 C10 A1

The image version: r32.3.1

Looks like default only have two mode. Does those two mode have problem?

< POWER_MODEL ID=0 NAME=MAXN > is BAD
< POWER_MODEL ID=1 NAME=5W > is OK, but slow

I didn’t repo the problem with default configure. It’s could be the device problem. You can send this device to RMA to get help.
