System Voltage Control

Determines whether to manually set the system voltages. Auto lets the BIOS automatically set the

system voltages as required. Manual allows all voltage control items below to be congurable. (Default:

Auto)

CPU PLL Voltage Control

Allows you to set the CPU PLL voltage.

Normal Supplies the CPU PLL voltage as required. (Default)

2.220V ~ 3.100V The adjustable range is from 2.220V to 3.100V.

Note: Increasing CPU voltage may result in damage to your CPU or reduce the useful life of the CPU.

DRAM Voltage control

Allows you to set memory voltage.

Normal Supplies the memory voltage as required. (Default)

1.275V ~ 2.445V The adjustable range is from 1.275V to 2.445V.

Note: Increasing memory voltage may result in damage to the memory or reduce the useful life of the

memory.

DDR VTT Voltage Control

Allows you to set the memory VTT voltage.

Normal Supplies the memory VTT voltage as required. (Default)

0.720V ~ 1.050V The adjustable range is from 0.720V to 1.050V.

Note: Increasing memory voltage may result in damage to the memory or reduce the useful life of the

memory.

NB Voltage Control

Allows you to set the North Bridge voltage.

Normal Supplies the North Bridge voltage as required. (Default)

1.000V ~ 1.600V The adjustable range is from 1.000V to 1.600V.

NB/PCIe/PLL Voltage Control

Allows you to set the North Bridge PCIe PLL voltage.

Normal Supplies the North Bridge PCIe PLL voltage as required. (Default)

1.450V ~ 2.100V The adjustable range is from 1.450V to 2.100V.

CPU NB VID Control

Allows you to set the CPU North Bridge VID voltage. Auto sets the CPU North Bridge VID 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.

Bank Interleaving

Enables or disables memory bank interleaving. Enabled allows the system to simultaneously access dif-

ferent banks of the memory to increase memory performance and stability. (Default: Enabled)

Channel Interleave

Enables or disables memory channel interleaving. Enabled allows the system to simultaneously access

different channels of the memory to increase memory performance and stability. (Default: Enabled)
