Chapter 3: BIOS setup

CPU PLL Voltage [Auto]

Allows you to select the CPU PLL voltage. The text color in the configuration

field corresponds to the onboard CPU LED color, both of which indicate voltage

condition. When you set the CPU LED Selection item to [CPU PLL], the onboard

CPU LED displays CPU PLL voltage condition. Refer to page 2-2 for CPU LED

definition. The values range from 1.81592V to 2.50000V with a 0.01325V interval.

QPI/DRAM Core Voltage [Auto]

Allows you to select the QPI/DRAM Core voltage. The text color in the

configuration field corresponds to the onboard CPU LED color, both of which

indicate voltage condition. When you set the CPU LED Selection item to [QPI/

DRAM Core], the onboard CPU LED displays QPI/DRAM Core voltage condition.

Refer to page 2-2 for CPU LED definition. The values range from 1.20000V to

2.50000V with a 0.00625V interval.

The QPI/DRAM Core voltage could be set only up to 1.8V when the Extreme

OV item is set to [Disabled].

IOH Voltage [Auto]

Allows you to set the I/O Hub (IOH) voltage. The values range from 1.11341V to

2.19991V with a 0.01325V interval.

IOH PCIE Voltage [Auto]

Allows you to set the IOH PCIE voltage. The values range from 1.51106V to

2.78306V with a 0.01325V interval.

ICH Voltage [Auto]

Allows you to set the I/O Controller Hub (ICH) voltage. The values range from

1.11341V to 2.00116V with a 0.01325V interval.

ICH PCIE Voltage [Auto]

Allows you to set the ICH PCIE voltage. The values range from 1.51106V to

2.05431V with a 0.01325V interval.

DRAM Bus Voltage [Auto]

Allows you to set the DRAM voltage. The values range from 1.51106V to 2.50000V

with a 0.01325V interval.

• The values of the CPU Voltage, CPU PLL Voltage, QPI/DRAM Core

Voltage, IOH Voltage, IOH PCIE Voltage, ICH Voltage, ICH PCIE Voltage,

and DRAM Bus Voltage items are labeled in different color, indicating the

risk levels of high voltage settings. Refer to below table for details.

• The system may need better cooling system to work stably under high

voltage settings.
