BIOS Setup

- 44 -

******** System Voltage Optimized ********

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 configurable. (Default:
Manual)

DDR3 Voltage Control

Allows you to set memory voltage.

Normal

Supplies the memory voltage as required. (Default)

+0.050V ~ +0.750V Increases memory voltage by 0.050V to 0.750V at 0.05V increment.

Note: Increasing memory voltage may result in damage to the memory.

NorthBridge Volt Control

Allows you to set the North Bridge voltage.

Normal

Supplies the North Bridge voltage as required. (Default)

+0.1V ~ +0.3V

Increases North Bridge voltage by 0.1V to 0.3V at 0.1V increment.

SouthBridge Volt Control

Allows you to set the South Bridge voltage.

Normal

Supplies the South Bridge voltage as required. (Default)

-0.1V ~ +0.2V

Increases South Bridge voltage by -0.1V to 0.2V at 0.1V increment.

SidePort Mem Volt Control

Allows you to set the SidePort memory voltage.

Normal

Supplies the SidePort memory voltage as required. (Default)

+0.1V ~ +0.3V

Increases SidePort memory voltage by 0.1V to 0.3V at 0.1V increment.

CHB DQS drive strength

Options are: Auto (default), 0.75x, 1.0x, 1.25x, 1.5x.

CHB Data drive strength

Options are: Auto (default), 0.75x, 1.0x, 1.25x, 1.5x.

CHB MEMCLK drive strength

Options are: Auto (default), 0.75x, 1.0x, 1.25x, 1.5x.

CHB Add/Cmd drive strength

Options are: Auto (default), 1.0x, 1.25x, 1.5x, 2.0x.

CHB CS/ODT drive strength

Options are: Auto (default), 1.0x, 1.25x, 1.5x, 2.0x.

CHB CKE drive strength

Options are: Auto (default), 1.0x, 1.25x, 1.5x, 2.0x.

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)
