How to boost the power of TX2 to 15W?

I heard that TX2’s standard power is 7.5W, if necessary, we can boost the power to 15W, so that the computing ability can reach 2 times of TX1. If so, where is the way?

You can set max clocks with this from the home directory:

sudo ./jetson_clocks.sh

This won’t guarantee using 15W, it just says to turn off power saving via clock throttling. One thing to consider is that unless you are running four CPU cores (meaning at least four software threads), plus GPU using CUDA, then you won’t even be using those parts even if clocks are maxed out.

However, you may like to use also"save" and “restore” functions with that:

sudo /home/ubuntu/jetson_clocks.sh --store       # save clocks config into l4t_dfs.conf file
sudo /home/ubuntu/jetson_clocks.sh               # boost clocks
sudo /home/ubuntu/jetson_clocks.sh --restore     # restore clocks config from l4t_dfs.conf file

or use nvpmodel

Hello Folks,

I accidentally deleted jetson_clocks.sh and tegrastats for Nvidia TX2.

Please share both the files or may be the link for the source code.

I am not able to find anywhere from my searches.

Thanks and Warm Regards,
Vaibhav

Just FYI, you can download the entire original file system via a combination of the driver package and sample rootfs. One normally unpacks the driver package first, which produces the “Linux_for_Tegra/” directory, and then (with sudo) unpack the sample rootfs to “Linux_for_Tegra/rootfs/”. Following this you would run “sudo ./apply_binaries.sh” from the “Linux_for_Tegra/” directory and this would put the NVIDIA specific modifications into the otherwise purely Ubuntu rootfs.

Then you would find “jetson_clocks.sh” in both “Linux_for_Tegra/rootfs/home/ubuntu/” and the “home/nvidia/” directories. “nvpmodel” would be found in “rootfs/usr/sbin/”.

You would want the same release you currently run. See “head -n 1 /etc/nv_tegra_release”. The different releases are listed here:
[url]https://developer.nvidia.com/embedded/linux-tegra-archive[/url]

Beware that you probably have to go there, log in, and then go there again (automatic redirect after login does not work).

Thanks a lot @linuxdev. I recovered both the files.
