ATI SMARTGART™ Tab SMARTGART™ is a suite of testing and diagnostics tools that perform a variety of bus tests to determine the optimal settings for your ATI graphics card. SMARTGART™ automatically configures your graphics card to the optimal settings. SMARTGART™ does not actually disable any AGP functionality in your computer's hardware. It simply instructs the ATI CATALYST™ driver not to use a specific AGP function if that function hasn't passed the SMARTGART™ diagnostics test. L Changing the AGP settings could result in system instability. Proceed with caution.
