4.4.1Chip Configuration

(Scroll down to see more items as shown.)

SDRAM Timing [By SPD]

This sets the optimal timings for items 2-4, depending on the memory modules that you are using. The default setting [By SPD] configures items 2-4 by reading the contents in the SPD (Serial Presence Detect) device. The EEPROM on the memory module stores critical parameter information about the module, such as memory type, size, speed, voltage interface, and module banks. Configuration options: [User Define] [By SPD]

SDRAM CAS Latency

This controls the latency between the SDRAM read command and the time that the data actually becomes available. NOTE: This field will only be adjustable when SDRAM Configuration is set to [User Define].

SDRAM RAS to CAS Delay

This controls the latency between the SDRAM active command and the read/write command. NOTE: This field will only be adjustable when SDRAM Configuration is set to [User Define].

SDRAM RAS Precharge Time

This controls the idle clocks after issuing a precharge command to the SDRAM. NOTE: This field will only be adjustable when SDRAM Configuration is set to [User Define].
