ATITool is an overclocking utility designed for ATI video cards.

Design target is to write a light-weight application for the enthusiast - so no questionable registry tweaks.

ATITool will only work on Windows 2000/XP/2003 (64 bit versions are supported).

Here are some key features of "ATITool":

1. No limits overclocking.
2. Finding maximum core and memory overclock by rendering into a Direct3D window and scanning the output for visual artifacts.
3. Temperature monitoring and fan speed control (on supported cards)

5. Artifact scanning mode for non-ATI cards - use together with a 3rd party overclocking utility.
6. Loading a predefined clock profile on Application/Windows startup.
7. Hotkeys that can be used any time to load clocks from a profile.
8. 3D application detection (Direct3D 8, Direct3D 9, OpenGL) to overclock your video card only when required.
9. Gamma control
