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)] for DDR; [200MHz (DDRII 400)], [266MHz (DDRII 533)] for DDRII.
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], [2.5], [2], and [3] for DDR; [Auto], [3], [4], [5] for DDRII.
DRAM Bank Interleave
Use this option to select DRAM Bank Interleave. Configuration options:
[Auto], [Disabled], [2-Way], [4-Way], and [8-Way]. The default value is set
to [Auto] to set the timing by dram SPD.
Precharge to Active (Trp)
Use this option to select Precharge to Active (Trp). Configuration options:
[Auto], [2T], [3T], [4T], and [5T]. The default value is set to [Auto] to set the
