SDRAM Configuration [By SPD]
This sets the optimal timings for SDRAM related fields, depending on the memory
modules that you are using. Default setting is [By SPD], which configures the sub-
sequent 3 items 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] [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: 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].
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].
