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]

PCI to DRAM Prefetch [Always Prefetch]

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]
