Configuration options: [4MB] [8MB] [16MB] [32MB] [64MB] [128MB] [256MB]

This motherboard supports the AGP 8X interface that transfers video data at
2.12GB/s. The configuration options vary depending on the speed of AGP card
installed. If an AGP 4X card is installed, configuration options will be [4X Mode].
The setting [8X Mode] will be the default if an AGP 8X card is installed. AGP 8X is
backward-compatible so you may keep the [4X Mode] setting, however the AGP
interface will only provide a peak data throughput of 1066MB/s even if you are
using an AGP 8X card. Configuration options: [8X Mode] [4X Mode]

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

card does not support this feature, otherwise the system may not boot.
