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: [166MHz (DDR 333)], [200MHz
(DDR 400)]. If DDRII DIMM is inserted to DDRII slot, you may select [200MHz
(DDRII 400)], [266MHz (DDRII 533)] as operating frequency.
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# 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. For DDR DIMM:
Configuration options are [3], [2.5], [2], and [Auto]. For DDRII DIMM:
Configuration options are [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], and [5 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], and [5 DRAM Clocks].
