Set Memory Clock
Determines whether to manually set the memory clock. Auto lets BIOS automatically set the
memory clock as required. Manual allows all voltage control items below to be configurable.
(Default: Auto)
Memory Clock
This option is configurable only when Set Memory Clock is set to Manual.
When you use an AM2 CPU:

******* System Voltage Optimized
System Voltage Control
Determines whether to manually set the system voltages. Auto lets BIOS automatically set the
system voltages as required. Manual allows all voltage control items below to be configurable.
(Default: Auto)
DDR2 Voltage Control
Allows you to set memory voltage.
Normal
+0.1V ~ +0.5V
NorthBridge Volt Control
Allows you to set the North Bridge voltage.
Normal
+0.1V ~ +0.3V
SouthBridge Volt Control
Allows you to set the South Bridge voltage.
Normal
+0.1V ~ +0.3V
CPU NB VID Control
Allows you to set the CPU Northbridge VID voltage. Normal sets the CPU Northbridge VID voltage
as required. (Default: Normal)
Note: Increasing CPU voltage may result in damage to your CPU or reduce the useful life of the CPU.
CPU Voltage Control
Allows you to set the CPU voltage. Normal sets the CPU voltage as required. The adjustable range
is dependent on the CPU being installed. (Default: Normal)
Note: Increasing CPU voltage may result in damage to your CPU or reduce the useful life of the CPU.
Normal CPU Vcore
Displays the normal operating voltage of your CPU.
(Note) This item is present only if you install a CPU that supports this feature.
