Asus Rampage II Extreme - Manual (Page 100)

3-18 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.
