4. BIOS SETUP

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]

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]

This feature allows you to select the size of mapped memory for AGP graphic

data. Configuration options: [4MB] [8MB] [16MB] [32MB] [64MB]
