ATITool is an overclocking utility designed for ATI and NVIDIA video cards.
Design target is to write a light-weight application for the enthusiast - so no questionable registry tweaks. Sorry.

Main Features

  • No limits overclocking.
  • Support for overclocking for NVIDIA cards.
  • Adjustment of GPU and memory voltage (when supported by VGA card).
  • Tweaking of memory timings (most ATI cards).
  • 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 to test for stability.
  • Loading a predefined clock profile on Application/Windows startup.
  • Hotkeys that can be used any time to load clocks from a profile.
  • Extract video card BIOS to file for backup purposes.
  • 3D application detection (Direct3D 8, Direct3D 9, OpenGL) to overclock your video card only when required.
  • Gamma control

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

ATITool is no longer in active development and will not support the latest graphics cards.
