38 SMARTGART™ 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 accelerator installed in your computer. SMARTGART automatically configures your graphics device 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 specific AGP function hasn't passed the SMARTGART diagnostics test. Changing the AGP settings could result in system instability. Set AGP Settings Experienced users can manually change the AGP speed. You will need to reboot your computer for this change to take effect. The possible AGP speed is dependent on the motherboard chipset and design. Your computer's available AGP speeds are shown in the SMARTGART dialog. Fast Write Fast Write allows the CPU to transfer data directly to the graphics accelerator. By default, this feature is set to ON providing your motherboard's chipset supports Fast Writes.
