How to Overclock Nvidia Video Cards in Linux

Nvidia Logo

Need to squeeze some extra juice out of your Nvidia video card? Want that extra FPS in your favourite shooter to secure your rank? The process is extremely simple and all you need to do is enable Coolbits which is popular in Windows. This tutorial can be done by any user who has some simple knowledge of the terminal and this should work with nearly any release of the nvidia’s unix drivers for the past year or so.

To start off be sure to have Nvidia’s drivers installed and working properly. Next go into terminal and make sure you are root (and for Ubuntu users simply follow the commands I do as I am using Ubuntu Gutsy). Open your favourite text editor, for me it is Nano due to its simplicity.

sudo nano /etc/X11/xorg.conf

Look for a section of code named “Device.” It should resemble something similar to this.

Section “Device”
Identifier “Videocard0″
Driver “nvidia”
VendorName “Videocard vendorname”
BoardName “nVidia Corporation Unknown device 0000″
EndSection

Now all you need to do is add this piece of code towards the end of the section.

Option “Coolbits” “1”

Now your xorg.conf should look like this.

Section “Device”
Identifier “Videocard0″
Driver “nvidia”
VendorName “Videocard vendorname”
BoardName “nVidia Corporation Unknown device 0000″
Option “Coolbits” “1”
EndSection

Save the file and exit out of terminal. Now you are all done, all you must do is restart X by restarting your machine or entering the following code in the terminal.

init 3 && init 5

Coolbits will now be located within the Nvidia Display Settings application. Good luck and if you have any questions or comments, please leave them below with your email address included (it will not be displayed, it is just for me to reply to your question).
