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)].
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].
DRAM RAS# Activate to Precharge
This controls the number of DRAM clocks for TRAS. Configuration options:
[4 DRAM Clocks], [5 DRAM Clocks], [6 DRAM Clocks], [7 DRAM Clocks], [8
DRAM Clocks], [9 DRAM Clocks], [10 DRAM Clocks], [11 DRAM Clocks], [12
DRAM Clocks], [13 DRAM Clocks], [14 DRAM Clocks], an d [15 DRAM
Clocks].
Primary Graphics Adapter
This allows you to select [PCI] or [PCI Express] as the boot graphic adapter
priority. The default value is [PCI].
OnBoard HD Audio
Select [Auto], [Enabled] or [Disabled] for the onboard HD Audio feature. If
you select [Auto], the onboard HD Audio will be disabled when PCI Sound
Card is plugged.
Front Panel Control
Select [Auto], [Enabled] or [Disabled] for the onboard HD Audio Front Panel.
CD-In
Use this item to enable or disable CD-In of OnBoard HD Audio.
OnBoard LAN
This allows you to enable or disable the “OnBoard LAN” feature.
VCCM (DRAM) Voltage
Use this to select VCCM (DRAM) Voltage. Configuration options: [High],
[Middle], [Low], and [Auto]. The default value of this feature is [Auto].
+1.5V Voltage
Configuration options: [High] and [Normal]. The default value of this feature
is [Normal].
