Graphics Aperture Size [128MB]
This feature allows you to select the size of mapped memory for AGP graphic data.
Configuration options: [128MB] [256MB]
AGP Capability [4X Mode]
This motherboard supports the AGP 4x interface that transfers video data at
1066MB/s. AGP 4X is backward-compatible, so you may keep the default [4X
Mode] even if you are using an AGP 1x video card. When set to [1X Mode], the
AGP interface only provides a peak data throughput of 266MB/s even if you are
using an AGP 4X card. Configuration options: [1X Mode] [2x Mode] [4X Mode]
AGP Fast Write Capability [Disabled]
This field allows enable or disable the AGP Fast Write feature. Configuration
options: [Disabled] [Enabled]
Onboard VGA Shared Memory Size [32MB]
This field allows you to set the size of shared memory for internal VGA.
Video Memory Cache Mode [UC]
USWC (uncacheable, speculative write combining) is a new cache technology for
the video memory of the processor. It can greatly improve the display speed by
caching the display data. You must set this to UC (uncacheable) if your display
card does not support this feature, otherwise the system may not boot.
Configuration options: [UC] [USWC]
