DRAM Clock [By SPD]
The DRAM clock are set according to the DRAM SPD (Serial Presence
Detect). You can manually set the DRAM clock parameters.
Configuration options: [By SPD] [133 MHz] [166 MHz]

DRAM Timing [Auto by SPD]
It is recommended that you set this parameter to [Auto by SPD]. Setting
to [Auto by SPD] synchronizes the DRAM timing with the DRAM clock.
Setting to [Manual] allows you to set the values for DRAM CAS Latency,
Bank Interleave, Pre-charge to Active (TRP) and Active to CMD (Trcd)
prameters. Configuration options: [Manual] [Auto By SPD] [Safe]

DRAM CAS Latency [2.5]DRAM CAS Latency [2.5]
DRAM CAS Latency [2.5]
Sets the override clock cycle for the latency time between the DRAM read
command and the moment that the data actually becomes available.
Normally, the system determines the rate automatically by default.
