4.4.1 Chip Configuration

The SDRAM parameters (items 2~5) become configurable only when

you set the SDRAM Configuration to [User Defined].

SDRAM CAS Latency [1.5T]

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]

SDRAM RAS to CAS Delay [3T]

This item controls the latency between the DDR SDRAM active command

and the read/write command. Configuration options: [3T] [2T]

SDRAM Configuration [By SPD]

This parameter allows you to set the optimal timings for items 2–5,

depending on the memory modules that you are using. The default setting

is [By SPD], which configures items 2–5 by reading the contents in the

SPD (Serial Presence Detect) device. 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 Defined] [By SPD]
