Chip Configuration
Bank Interleave [Auto]
Configuration options: [None] [2 Banks] [4 Banks] [Auto]
DDR_1T/2T_ITEM [2T CMD]
Configuration options: [1T CMD] [2T CMD] [Auto Mode]
SDRAM Data Integrity Mode [Non-ECC]
This function allows you to select whether your DIMM modules support
the ECC feature or not. Configuration options: [Non-ECC] [ECC]
Read Around Write [Enabled]
Setting this field to [Enabled] allows the memory controller to store write
data in its buffer whenever the CPU issues a write command. The next time
the CPU needs the data, it retrieves the data from the memory buffer without
accessing the SDRAM. Configuration options: [Disabled] [Enabled]

Configuration options: [Always Prefetch] [Prefetch Disabled] [Prefetch Only
Enhance Command]
Delayed Transaction [Disabled]
When set to [Enabled], this feature frees the PCI bus when the CPU is
accessing 8-bit ISA cards. This process normally consumes about 50-60
PCI Clocks without PCI delayed transaction. Set this field to [Disabled]
when using ISA cards that are not PCI 2.1 compliant. Configuration options:
[Enabled] [Disabled]
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 leave the default
[4X Mode] on even if you are using an AGP 1x or 2x 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 2x/4x card. When set to [2X Mode],
the AGP interface only provides a peak data throughput of 533MB/s even if
you are using an AGP 4x card. Configuration options: [1X Mode] [2X Mode]
[4X Mode]
AGP Fast Write [Disabled]
Configuration options: [Disabled] [Enabled]
Graphics Aperture Size [64MB]
This feature allows you to select the size of mapped memory for AGP graphic
data. Configuration options: [4MB] [8MB] [16MB] [32MB] [64MB]
[128MB]
