SDRAM Configuration [By SPD]

This sets the optimal timings for items 2–4, depending on the memory mod- ules that you are using. Default setting is [By SPD], which 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 mod- ule banks. Configuration options: [User Define] [7ns (143MHz)] [8ns (125MHz)] [By SPD]

SDRAM CAS Latency

This controls the latency between the SDRAM read command and the time that the data actually becomes available. NOTE: To make changes to this field, the SDRAM Configuration field must be set to [User Define].

SDRAM RAS to CAS Delay

This controls the latency between the SDRAM active command and the read/write command. NOTE: To make changes to this field, the SDRAM Configuration field must be set to [User Define].
