SDRAM Capability

This field displays the capability of the memory modules that you are using either PC100 or PC133.

SDRAM Operating Mode

This field displays the current SDRAM operating mode (PC100 or PC133) according to the SDRAM frequency you configure in the Advanced menu.

SDRAM Timing [By SPD]

This sets the optimal timings for items 4-7, depending on the memory modules that you are using. The default setting [By SPD] configures items 4-7 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.

SDRAM RAS to CAS Delay

This controls the latency between the SDRAM active command and the read/write command.
