ATI bietet zum AGP Diagnose-Utility Smartgart eine Dokumentation an. Neben ein paar FAQs, wird auch ein PDF-Dokument zum herrunterladen angeboten.

Q1: Does SMARTGART disable all AGP support including AGP reads, AGP writes, and AGP fast writes)?
A1: No. SMARTGART tests the functionality of each AGP command and determines if your system is capable of supporting each one, and will only enable it if system stability is maintained. Please note that SMARTGART does not disable or turn off AGP support in your actual hardware; SMARTGART only ensures that the ATI CATALYST driver will not use an AGP function that has been deemed to be unstable.
Q2: Can I disable SMARTGART?
A2: SMARTGART cannot be disabled, but it can be removed from your system. Please note that SMARTGART will only be installed if the ATI setup program is used to install the display driver. To remove SMARTGART, use the Windows->Control Panel->Add or Remove option to uninstall the ATI CATALYST display driver. When the system is restarted the operating system will inform you that "New Hardware" has been detected. Locate the directory where the driver is located and complete the driver installation. The ATI driver will now be installed without SMARTGART.

Q3: Are ATI’s products capable of supporting fast writes?
A3: Yes. The RADEON 9700 PRO, RADEON 9700, RADEON 9500 PRO, RADEON 9500, RADEON 9000 PRO, RADEON 9000 and the RADEON 8500 are capable of supporting fast writes when using an ATI CATALYST based display driver. Of course fast writes must also be supported on the motherboard you are using and be enabled in the system BIOS. In order for fast writes to be used by ATI’s driver, fast writes must also pass the SMARTGART diagnostics test. ATI products previous to the RADEON 8500 as well as the RADEON 8500 DV are not capable of supporting fast writes.
