Advanced DRAM Configuration
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)], [333MHz (DDRII 667)]. The configuration options may change
according to the corresponding FSB frequency of the CPU you adopt.
Flexibility Option
The default value of this option is [Disabled]. It will allow better tolerance for
memory compatibility when it is set to [Enabled].
DRAM CAS# Latency
Use this item to adjust the means of memory accessing. Configuration
options: [Auto], [3], [4], and [5]. Please note that the configuration option
[3] is available only for FSB 800 and FSB 533.
DRAM RAS# to CAS# Delay
This controls the latency between the DRAM active command and the
read / write command. Configuration options: [Auto], [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: [Auto], [2 DRAM Clocks], [3 DRAM Clocks],
[4 DRAM Clocks], [5 DRAM Clocks] and [6 DRAM Clocks].
DRAM RAS# Activate to Precharge
This controls the number of DRAM clocks for TRAS. Configuration
options: [Auto], [4 DRAM Clocks] to [15 DRAM Clocks].
