4. BIOS SETUP

SDRAM Active to Precharge Time [6T]

To make changes to this field, set the SDRAM Configuration field to [User Defined]. Configuration options: [6T] [5T]

SDRAM Data Driving Strength [Auto]

Configuration options: [Auto] [Strong]

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]

CPU-DRAM Back-Back Transaction [Enabled]

Configuration options: [Disabled] [Enabled]

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]

PCI to DRAM Prefetch [Disabled]

Configuration options: [Disabled] [Enabled]

Byte Merge [Disabled]

To optimize the data transfer on PCI, this feature combines a sequence of individual memory writes (bytes or words) into a single 32-bit block of data. However, byte merging may only be done when the bytes within a data phase are in a prefetchable address range. Configuration options: [Disabled] [Enabled]

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]
