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":

· No limits overclocking.
· Finding maximum core and memory overclock by rendering into a Direct3D window and scanning the output for visual artifacts.
· Temperature monitoring and fan speed control (on supported cards)
· Removal of Catalyst overclocking lock for 9000/9200/9550/9600 series.
· Artifact scanning mode for non-ATI cards - use together with a 3rd party overclocking utility.
· Loading a predefined clock profile on Application/Windows startup.
· Hotkeys that can be used any time to load clocks from a profile.
· 3D application detection (Direct3D 8, Direct3D 9, OpenGL) to overclock your video card only when required.
· Gamma control


Note: Free for non-commercial use only.
