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.
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.
Some motherboard specifications may claim chipset
support for Fast Writes but may not be compatible
with many different graphics accelerators.
Changing the AGP settings could result in
system instability
