How to overclock nVidia cards with Coolbits

Once Coolbits has been activated, overclocking an nVidia-based card is simple. Open up the 'display' applet in control panel, then go to 'settings' and 'advanced'. Click on the tab with the nVidia logo and the name of the videocard to open up the nVidia video card control application.

From the menu, choose the 'clock frequency' option.

Change the 'settings' drop-down box to 'performance (3D)'. This will show the default core and memory clock speeds for the video card when it is running in 3D mode.

Using the sliders, the video card's core and memory speeds can now be overclocked. Before the new settings can be confirmed, they will need to be tested using the 'test settings' button. Once the settings have been affirmed by using this button, the card will be set to the new speeds.

Please note that just because the overclocked settings pass this test does not necessarily mean that the same settings will work for games or benchmarks. In PCstats' experience though, this test button seems to err on the side of caution, so readers may be able to squeeze more out of their cards than the test button lets them get away with. This is when we need to turn to a third-party application to overclock further, which is a subject covered a little later in this article.

The 'auto-detect' button will overclock the card's core and memory speeds automatically to a 'safe' margin. In our experience, this tends to be quite close to the maximum speeds obtainable with any given card in Coolbits. It can be considered a good jumping-off point.

Do not use the auto-detect button if the sliders have already been changed manually, since this can give some seriously strange results and occasionally crash the system. Hit the 'default settings' button to return the sliders to normal first.

The 'apply settings at startup' button will reapply any custom clock speed settings each time the computer is restarted. With Coolbits, this works most of the time. It may be worthwhile to double-check that the new settings have stuck after a reboot.
