revised how to: We'll work as root to avoid having to type sudo everytime..
Open Terminal
Code:
nano -w .nvidia-settings-rc
Delete the lines:
GPUOverclockingState=1
GPU2DClockFreqs=513,792
GPU3DClockFreqs=513,792
CTRL+x, then "y" then "enter"
Next we will enable coolbits in xorg.conf
Code:
nano -w /etc/X11/xorg.conf
Add the line Option "Coolbits" "1" as seen in the example below
Code:
Section "Device"
Identifier "Videocard0"
Driver "nvidia"
Option "AddARGBGLXVisuals" "True"
Option "Coolbits" "1"
EndSection
CTRL+x then "y" then "enter"
Now we will restart the X-server by hitting CTRL+ALT+Backspace. Log back in..
Go to Applications --> System Tools --> nVidia Display Settings, click on the overclocking tab on the left and it will bring up this screen.. check the box to enable overclocking. Go to 3D Clock frequencies and bump each 20 or so, I don't have Quake4 so I I can't tell you what can be used as a benchmark, so just play a little quake. Once you reach a comfortable
OC, then you would want to edit the .nvidia-settings-rc file with those clocks so that it will boot with those settings from that point on. Coolbits will still allow clock changes on the fly..
