Activate CPUs
By default 4 out of 12 possible CPU cores are disabled on the Jetson Orin. You can activate them with the following commands:
First is necessary to access as root (you need root permissions)
sudo su
Then, you can activate the CPU cores:
echo 1 > /sys/devices/system/cpu/cpu4/online echo 1 > /sys/devices/system/cpu/cpu5/online echo 1 > /sys/devices/system/cpu/cpu6/online echo 1 > /sys/devices/system/cpu/cpu7/online exit
You must activate all CPUs before running jetson_clocks to overclock these CPUs too.
Jetson Clocks
Orin provides the jetson_clocks.sh script to maximize Jetson Orin performance by setting static max frequency to CPU, GPU, and EMC clocks. The script can also be used to show current clock settings, store current clock settings into a file, and restore clock settings from a file.
Options
--show Displays the current settings. --store [file] Stores the current settings to a file. The default file is l4t_dfs.conf. --restore [file] Restores the saved settings from the file. The default file is l4t_dfs.conf.
- To show the current settings:
sudo jetson_clocks --show
- To store the current settings:
sudo jetson_clocks --store
- To maximize Jetson Orin performance
sudo jetson_clocks
- To restore the previous settings
sudo jetson_clocks --restore
