More on overclocking your Nvidia graphics card

In an earlier article, I mentioned ways to overclock your Nvidia graphics card in Ubuntu 9.04.

There is one more detail you will need.

Normally, when you restart the system, the overclocking settings will be lost.

Here's how to fix that:

Open a terminal and type "gnome-session-properties"
Add a new item
Call it 'nvclock'
The command is 'nvclock -b coolbits -n 575.000 -m 999.000' in my case.

The -n is the GPU speed and the -m is the memory speed.

Therefore your system will now start with an overclocked graphics card.

If you're using this command in a shell, there may be an error if you are trying to push your card further than the 'known' safe limits. You can add the '-f' switch to force the overclocking, both at the command line and in the gnome-session-properties panel. Sometimes, nvclock doesn't correctly identify the card. If you're sure you know better, then you make the choice. It identified my GTX260 as a standard edition rather than a special overclock edition. Therefore, I forced the settings.

Remember, some parameters may be too extreme and damage your hardware.

Peace out...
