# OPTIONAL: Setting NVIDIA GPU Power Limit at System Startup
|
|
|
|
## Overview
|
|
|
|
This guide explains how to set the power limit for NVIDIA GPUs at system startup using a systemd service. This ensures the power limit setting is persistent across reboots.
|
|
|
|
## Steps
|
|
|
|
### 1. Create and Configure the Service File
|
|
|
|
1. Open a terminal and create a new systemd service file:
|
|
|
|
```bash
|
|
sudo nano /etc/systemd/system/nvidia-power-limit.service
|
|
```
|
|
|
|
2. Add the following content to the file, replacing `270` with the desired power limit (e.g., 270 watts for your GPUs):
|
|
|
|
- For Dual GPU Setup:
|
|
|
|
```ini
|
|
[Unit]
|
|
Description=Set NVIDIA GPU Power Limit
|
|
|
|
[Service]
|
|
Type=oneshot
|
|
ExecStart=/usr/bin/nvidia-smi -i 0 -pl 270
|
|
ExecStart=/usr/bin/nvidia-smi -i 1 -pl 270
|
|
|
|
[Install]
|
|
WantedBy=multi-user.target
|
|
```
|
|
|
|
- For Quad GPU Setup:
|
|
|
|
```ini
|
|
[Unit]
|
|
Description=Set NVIDIA GPU Power Limit
|
|
|
|
[Service]
|
|
Type=oneshot
|
|
ExecStart=/usr/bin/nvidia-smi -i 0 -pl 270
|
|
ExecStart=/usr/bin/nvidia-smi -i 1 -pl 270
|
|
ExecStart=/usr/bin/nvidia-smi -i 2 -pl 270
|
|
ExecStart=/usr/bin/nvidia-smi -i 3 -pl 270
|
|
|
|
[Install]
|
|
WantedBy=multi-user.target
|
|
```
|
|
|
|
Save and close the file.
|
|
|
|
### 2. Apply and Enable the Service
|
|
|
|
1. Reload the systemd manager configuration:
|
|
|
|
```bash
|
|
sudo systemctl daemon-reload
|
|
```
|
|
|
|
2. Enable the service to ensure it runs at startup:
|
|
|
|
```bash
|
|
sudo systemctl enable nvidia-power-limit.service
|
|
```
|
|
|
|
### 3. (Optional) Start the Service Immediately
|
|
|
|
To apply the power limit immediately without rebooting:
|
|
|
|
```bash
|
|
sudo systemctl start nvidia-power-limit.service
|
|
```
|
|
|
|
## Verification
|
|
|
|
Check the power limits using `nvidia-smi`:
|
|
|
|
```bash
|
|
nvidia-smi -q -d POWER
|
|
```
|
|
|
|
Look for the "Power Management" section to verify the new power limits.
|
|
|
|
By following this guide, you can ensure that your NVIDIA GPUs have a power limit set at every system startup, providing consistent and controlled power usage for your GPUs. |
