With NVIDIA's latest driver release, CoolBits has been released for Linux. This overclocking utility is the subject of this tutorial.
A few months ago here at Phoronix we published an article entitled "The State of Linux NVIDIA Overclocking", which expressed our views of the overclocking options available, or there the lack of, to Linux NVIDIA users. Up until this time, NVClock has been one of the only utilities available to overclock your NVIDIA based graphics card under Linux, without using a BIOS editor. However, when we last tested the NVClock 0.8 CVS we still experienced several problems when paired up with some of our latest NVIDIA 6XXX and FX graphics cards. Although Thunderbird has done a phenomenal job, and continues to do a magnificent job developing NVClock, there still is a lack of overclocking options available for NVIDIA Linux users. NVIDIA, however, has released its new drivers that include some interesting features.
In addition to Xinerama and OpenGL 2.0 support, CoolBits also accompanies this latest package. For those who haven't heard of or never used CoolBits, this is a NVIDIA overclocking utility for Microsoft Windows (until now) which could be enabled by a simple registry tweak and allows the user to substantially increase their VPU and memory speeds. However, does this CoolBits Linux port offer the reliability of its Windows counterpart and fix the issues that NVClock has yet to address? Today we have a short guide on how to enable CoolBits with these new NVIDIA drivers (1.0-7664), how to change your core and memory speeds, and the results we obtained when using the CoolBits utility.

There is a Way to Make Linux auto load the over clock settings
First off there is a file in your home directory named
.nvidia-settings-rc
since it has . in front of its name it means its hidden you have to make it so you can see hidden files.
in KDE you can do that by going into your home directory
and in the menus click View->Show Hidden Files
find .nvidia-settings-rc
double click on it
now dont do it yet because im going to explain something.
if you add these lines to the bottom of that file it will load
these over clock settings.
echo 0/GPUOverclockingState=1
echo 0/GPU2DClockFreqs=432,1125
echo 0/GPU3DClockFreqs=432,1125
but there is one big problem once you close nvidia-settings
these lines will get deleted again and it would be a pain to
add them all the time.
before that im going to explain the lines
This Line turns on the ability to overclock
echo 0/GPUOverclockingState=1
This is your 2D overclock settings
echo 0/GPU2DClockFreqs=432,1125
This is your 2D overclock settings
echo 0/GPU3DClockFreqs=432,1125
the 432 is what i have my GPU Clock Speed at and the
1125 is what i have the ram clock speed at.
so what we are going to do is make our own script that adds them
to the bottom of the file after it closes.
if you are in kde you need to open the Konsole
copy the below lines and then paste them into the konsole
then press enter
