Main Features
As the name implies 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.

  • 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

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

  • Fixes to card detection on some ATI chipsets
  • Fixed "When setting the speed in the log the selected speed is shown not the actual speed it is set to." (#38)
  • Added infobox about possible problems when FRAPS is running
  • Removed fan control tab for 9600.
  • Some fixes to "try to keep gpu temp at". It will only work while ATITool is running. If you close ATITool fan speeds are set to ATI's defaults
  • Fixed temp. reading error which showed 20° on 9800s with high load sometimes
  • Disabled creation of file C:\Atitool detection log.txt
  • Fixed excessive log entries generated during Find Max (#29)
  • Fixed 3D detection for XP SP2 + AMD64 (#25)
  • Forced 3D detection on for all executables starting with "bf_vietnam" (Battlefield: Vietname) until a proper fix is found
  • Forced 3D detection on for all executables starting with "nwmain" (Neverwinter Nights) until a proper fix is found
  • Fixed rounding error in fan speed settings (#16)
  • Fixed rounding error in font size display in temp. settings (#23)
  • Added current fan speed display to fan speed settings (#22)
  • Memory timings editor is active now - values are not permanent and are reset at reboot. USE AT YOUR OWN RISK.
  • Gamma settings are reapplied when display mode is changed (#14)
  • Gamma settings panel shows numbers (#14)
  • Added fan control option "Try to keep GPU temp. at xx°C" - this option is only available if temp. monitoring is enabled
  • Added mini stats to temp. monitoring settings page
  • Several speed optimized artifact detection code
  • Dump bios button disabled on 9200 until a fix is found
  • Replace temp. remote / local by "GPU" / "GPU environment"
  • Fixed cosmetic bug in temp. settings panel (#15)
  • Fixed bug with log file max. size .. the value was interpreted as Bytes (#13)
  • Added include list for 3D detection
  • No "scan running" message to log file right after start
  • Fixed crash in 3D detection for 3dmark2001 and probably other apps
  • Gamma hotkeys are disabled when gamma control is disabled
  • Lots of fixes based on the great feedback after the 0.0.21 release, critical fixes are already incorporated into the 0.0.21 download
  • Added option to scanning settings: "disable screensaver while scanning"
  • Fixed ATI fan control. for some reason ATI defaults result in fan speeds > 100% to be programmed. This means that any fan speed >75% is actually 100% (can't run the fan faster than 100%). ATITool fixes this by setting the right register on the temp. chip.
  • Moved fan speed registry key so its not lost every time you reinstall ATITool
