Jetson TX2 turns on high power mode
Article directory
I. Introduction
Jetson TX2 development can be connected to an external monitor, or you can use VNC and Nomachine
for remote linking. Here is an introduction to using Nomachine to visually connect to Jetson TX2.
We need to install Nomachine on both the host (Jetson TX2) and the slave (Windows).
After the master and slave terminals are installed, under the same LAN, the slave terminal can automatically capture the host IP and verify the slave password to connect.
At this point, you can adjust the resolution
xrandr --fb 1920x1080
2. Turn on high power consumption
TX2 拥有6个 CPU 核心和一个 GPU
Nvidia's new command tool Nvpmodel provides 5 modes. The CPU and GPU frequencies corresponding to different working modes are as follows:
| Mode | Mode Name | Denver 2 | Frequency | ARM A57 | Frequency | GPU Frequency |
|---|---|---|---|---|---|---|
| 0 | Max-N | 2 | 2.0 GHz | 4 | 2.0 GHz | 1.30 GHz |
| 1 | Max-Q | 0 | 4 | 1.2 GHz | 0.85 GHz | |
| 2 | Max-P Core-All | 2 | 1.4 GHz | 4 | 1.4 GHz | 1.12 GHz |
| 3 | Max-P ARM | 0 | 4 | 2.0 GHz | 1.12 GHz | |
| 4 | Max-p Denver | 2 | 2.0 GHz | 0 | 1.12 GHz |
The default mode of TX2, Max-Q, only turns on 4 CPUs. To maximize the power, you need to switch to Max-N mode.
① Check the current mode
sudo nvpmodel -q verbose
or
sudo nvpmodel --query
② Switch to Max-N mode
sudo nvpmodel -m 0
Check
③ Turn the power to the maximum
and run the jetson_clocks.sh file in the home directory
sudo ./jetson_clocks.sh
This will enable high power consumption
3. Summary
At this point, you can see that the small fan on the Jetson TX2 is spinning.
