Linux NVIDIA GPU overclocking Guide

The Guide Part 1

First enable cool-bits

sudo nvidia-xconfig -a --cool-bits=28

Next we will edit the xorg config file

sudo nano /etc/X11/xorg.conf

Scroll down till you find Section "Screen"

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "Coolbits" "28"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

Add this line under [Option "Coolbits" "28"]

Option         "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerDefaultAC=0x1"

So it looks like this

Section "ScreeSection "Screen"
    Identifier     "Screen0"SectioSection "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "Coolbits" "28"
    Option         "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerDefaultAC=0x1"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

Once done reboot.

The Guide Part 2

Next lets create a overclocking script to overclock our gpu automatically

The number "#1" has to be the same and number "#" can be any number. Make sure those numbers match in the NVIDIA X Server Settings.

sudo nano /usr/bin/overclock.sh
!/bin/bash
nvidia-settings -a '[gpu:0]/GPUGraphicsClockOffset[1]=#'

nvidia-settings -a '[gpu:0]/GPUGraphicsMemoryOffset[1]=#1'

nvidia-settings -a '[gpu:0]/GPUMemoryTransferRateOffset[1]=#1'

nvidia-settings -a '[gpu:0]/GPUFanControlState=1'

nvidia-settings -a '[fan:0]/GPUTargetFanSpeed=#'

Next make it executable

sudo chmod +x /usr/bin/overclock.sh

And add it to startup for XFCE its in Application>Settings>Settings Manager>Session and Startup>Application Autostart Then click on Add. Give it a name, desciption and in command type

bash /usr/bin/overclock.sh

That will automatically overclock your GPU at startup.

To make sure it works reboot for the last and final time and enjoy your overclocked GPU.
