# Control your GPU on Linux

# 1. NVIDIA
## 1. Install drivers
## 2. Configuration
### 2.1 Generate config File: /etc/X11/xorg.conf

sudo nvidia-xconfig

## 2.2 Installation [GWE](https://gitlab.com/leinardi/gwe)

sudo apt install python3-pip python3-dev python3-cairo-dev build-essential cmake gcc meson ninja-build libgirepository1.0-dev gir1.2-appindicator3-0.1 libdazzle-1.0-dev gnome-shell-extension-appindicator appstream-util libxml2-utils

Build from source

mkdir Projects
cd Projects
git clone --recurse-submodules -j4 https://gitlab.com/leinardi/gwe.git
cd gwe
git checkout master
sudo -H pip3 install python3-cairo-dev PyGObject
sudo -H pip3 install -r requirements.txt
meson . build --prefix /usr
ninja -v -C build
sudo ninja -v -C build install

### 3. Change configuration file

sudo gedit /etc/X11/xorg.conf


Structure:

Section "Device"
      Identifier     "Device0"
      Driver         "nvidia"
      VendorName     "NVIDIA Corporation"
      BusID          "PCI:1:0:0"
      BoardName      "NAME OF YOUR CARD"
      Option         "Coolbits" "8"  # bits FERMI+
EndSection

Change to(Example of my case):

Section "Device"
      Identifier     "Device0"
      Driver         "nvidia"
      VendorName     "NVIDIA Corporation"
      BusID          "PCI:1:0:0"
      BoardName      "NVIDIA RTX 6000 Ada Generation"
      Option         "Coolbits" "8" 
EndSection

#### Coolbits it's the most important parameter.

The Coolbits value is the sum of its component bits in the binary numeral system. The component bits are:

1 (bit 0) - Enables overclocking of older (pre-Fermi) cores on the Clock Frequencies page in nvidia-settings.
2 (bit 1) - When this bit is set, the driver will "attempt to initialize SLI when using GPUs with different amounts of video memory".
4 (bit 2) - Enables manual configuration of GPU fan speed on the Thermal Monitor page in nvidia-settings.
8 (bit 3) - Enables overclocking on the PowerMizer page in nvidia-settings. Available since version 337.12 for the Fermi architecture and newer.[4]
16 (bit 4) - Enables overvoltage using nvidia-settings CLI options. Available since version 346.16 for the Fermi architecture and newer.[5]
To enable multiple features, add the Coolbits values together. For example, to enable overclocking and overvoltage of Fermi cores, set Option "Coolbits" "24".


### 4. If you want by CLI

Structure PowerLimit: nvidia-smi -i CARD_NUMBER -PL (W power limit)

sudo nvidia-smi -i 0 -pl 250

Structure GPU & Memory offset:

nvidia-settings -a [gpu:0]/GPUGraphicsClockOffset[3]=50
nvidia-settings -a [gpu:0]/GPUMemoryTransferRateOffset[3]=500
