DRAM Frequency
If [Auto] is selected, the motherboard will detect the memory module(s) inserted and assigns appropriate frequency automatically. You may also select other value as operating frequency: [200MHz (DDRII 400)], [266MHz (DDRII 533)].
Flexibility Option
The default value of this option is [Disabled]. It will allow better tolerance for memory compatibility when it is set to [Enabled].
Configure DRAM Timing by SPD
Select [Enabled] will configure the following items by the contents in the SPD (Serial Presence Detect) device. If you select [Disabled], you will find the items “DRAM RAS# to CAS# Delay”, “DRAM RAS# Precharge”, and “DRAM RAS# Activate to Precharge” appear to allow you adjusting them.
DRAM CAS# Latency
Use this item to adjust the means of memory accessing. Configuration options are [6], [5], [4], [3], and [Auto].
DRAM RAS# to CAS# Delay
This controls the latency between the DRAM active command and the read / write command. Configuration options: [2 DRAM Clocks], [3 DRAM Clocks], [4 DRAM Clocks], [5 DRAM Clocks], and [6 DRAM Clocks].
DRAM RAS# Precharge
This controls the idle clocks after a precharge command is issued. Configuration options: [2 DRAM Clocks], [3 DRAM Clocks], [4 DRAM Clocks], [5 DRAM Clocks], and [6 DRAM Clocks].
