SDRAM CAS Latency
(value depends on SDRAM SPD)
This item controls the latency between the SDRAM read command and the time
the data actually becomes available. Configuration options: [2.5T] [2T] [1.5T] [3T]
SDRAM RAS to CAS Delay
(value depends on SDRAM SPD)
This item controls the latency between the DDR SDRAM active command and the
read/write command. Configuration options: [3T] [2T] [4T]
SDRAM RAS Precharge Time
(value depends on SDRAM SPD)
This item controls the idle clocks after issuing a precharge command to the DDR
SDRAM. Configuration options: [3T] [2T] [4T]
SDRAM RAS Active Time
(value depends on SDRAM SPD)
This item controls the number of DDR SDRAM clocks used for DDR SDRAM
parameters. Configuration options: [6T] [7T] [5T] [9T]
Chipset Clock Mode [Synchronous]
This item sets the chipset clock mode.
Configuration Options: [Synchronous] [Asynchronous]
SDRAM Command Lead-off Time [Auto]
Configuration options: [Auto] [2T] [1T]
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] [256MB]
AGP Capability [8X Mode]
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.
AGP Fast Write Capability [Enabled]
This field enables or disables the AGP 4x Fast Write Capability feature.
Configuration options: [Disabled] [Enabled]
The EEPROM on the memory module stores critical information about the module,
such as memory type, size, speed, voltage interface, and module banks.
Configuration options: [User Define] [By SPD]
The SDRAM parameters (items 2~5) become configurable only when you set
the SDRAM Configuration to [User Define].
