Using ATITool


ATiTool main window

The first thing you must do now is to create a new “Default” profile in ATITool. Unfortunately any profile name that begins with Default is reserved, but you can call it anything you like (e.g. “DefClocks”, “DefSettings” etc). Once this profile has been created, you must now set the 3D voltages for your card.

Navigate to the voltage adjustment feature of ATITool (Settings > Voltage Control) and increase your VGPU to 1.425v (remember, this is the default voltage of the GPU under the 3D mode). Save the voltage settings to the profile you created.

Now go back to the main screen and manually type in your video card’s 3D frequencies in the appropriate box (for example, if you have an x1900XT, under “Core” you would type 625 and under “Memory” you would type 750).

Now select the new profile you created and click “Save”. Now you have a profile that contains your correct 3D mode settings. You may choose to let ATITool run this profile at startup if you have disabled ati2evxx.exe just so you get the right performance from your card (otherwise your card will operate at 500MHz/600MHz).

You may also choose to manually configure your x1900’s fan speed from ATITool, which you can include in your “default” profile. You may experiment to see what fan speed is optimal for your setup (for stock clocks, GPU temperature should not go above 65-70 degrees C).

Now I suggest you run 3DMark05 or some other benchmark so you get an idea of what your “stock” (default) scores are.



When running games/benchmarks the video card will heat up quickly, having proper (case) cooling is advised ->
