The AGX Orin 64GB has several power modes: 15W, 30W, 50W and MAXN mode (unrestricted). To toggle between them, you can use the following commands:

# Free up current memory
sudo sync; sudo sysctl -w vm.drop_caches=3

#version are 
# 0 (max)
# 3 (50)
# 2 (30)
# 1 (15)

# set to max mode
sudo nvpmodel -m 0
sudo jetson_clocks

# confirm with:
sudo nvpmodel -q

Once you set your power, you’ll want to clock the Orin, which does several things:

• Maximizes CPU frequency
• Maximizes GPU frequency
• Maximizes memory and bus frequencies
• Sets fan speeds

sudo jetson_clocks                # Max performance
sudo jetson_clocks --show         # Show current frequencies
sudo jetson_clocks --restore      # Restore default dynamic scaling
