Utility for controlling RGB header on MSI boards
This utility not only works on any linux system you find around, it also is much more flexible than the 7 colours MSI’s own Gaming App. Futhermore, unlike the MSI’s utility, this does not make your system vulnerable to anybody who cares to fiddle around the system.
- Linux (/dev/port, might work on WSL?) or FreeBSD (/dev/io);
- Only MSI motherboards with NCT6795D super I/O chip;
- Run a recent version of sensors-detect to check if you have this chip;
- No warranty whatsoever (read the license);
- If you find your board misbehaving, try clearing CMOS;
This is a list of reportedly working motherboards. If the tool works on your motherboard and it is not listed here, consider filling an issue or writing me an email and I’ll add it here.
- B350 MORTAR ARCTIC
- B350 TOMAHAWK
- H270 MORTAR ARCTIC
- H270 TOMAHAWK ARCTIC
- X470 GAMING PRO
- X470 GAMING PLUS
- Z270 SLI PLUS
- Z370 MORTAR
If your board is not working, and your motherboard is not on this list, a new issue would be greatly appreciated.
To compile this project you’ll need rustc and cargo. Get them at your package manager or here.
Then:
git clone https://github.com/nagisa/msi-rgb
cd msi-rgb
cargo build --release
You’ll need root to run this program:
sudo ./target/release/msi-rgb 00000000 FFFFFFFF 00000000 # for green
The hexa numbers represent each color as a sequence in time per byte so 4 change of colors.
sudo ./target/release/msi-rgb FF000000 00FF0000 0000FF00 # this makes red then green then blue then off then red etc..
Run following for more options:
./target/release/msi-rgb -h
sudo ./target/release/msi-rgb 206487a9 206487a9 10325476 -ir -ig -ib -d 5
sudo ./target/release/msi-rgb -d15 FF00FF00 0 00FF00FF
sudo ./target/release/msi-rgb 58e01c0d 504fdcb9 e4aa75eb --blink 2 -d 32
echo -e "import colorsys, time, subprocess\ni=0\nwhile True:\n subprocess.call(['target/release/msi-rgb', '-d511'] + map(lambda x: ('{0:01x}'.format(int(15*x)))*8, colorsys.hsv_to_rgb((i % 96.0) / 96.0, 0.9, 1)))\n time.sleep(0.1)\n i+=1" | sudo python -
