'''Coolbits''' was a [Windows registry](/source/Windows_registry) [hack](/source/Hacker_(hobbyist)) for [Nvidia](/source/Nvidia) [graphics cards](/source/graphics_cards) [Windows](/source/Microsoft_Windows) drivers, that allows [tweaking](/source/tweaking) features via the Nvidia driver control panel (including [overclocking](/source/overclocking)).
There is also a Coolbits 2.0, with extra features.
These features provided by Coolbits are considered expert-only and thus the reason they are normally hidden in the control panel.

Below is the main Coolbits activation entry in the registry:
 [HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\NvTweak]
 "CoolBits"=dword:00000003 

It is also available on [Unix-like](/source/Unix-like) systems running the [X Window System](/source/X_Window_System) by setting the "Coolbits" option to "5" in [the configuration file](/source/xorg.conf). Using "28" instead of "5" will enable additional overclocking features.<ref>[http://us.download.nvidia.com/XFree86/Linux-x86_64/173.08/README/chapter-07.html Nvidia - Chapter 7.
