Chapter 2 Installation and BIOS Setup
Intel Virtualization Technology
Select Enable to use Intel Virtualization Technology so that I/O device assignments will be
reported directly to the VMM (Virtual Memory Management) through the DMAR ACPI Tables.
This feature offers fully-protected I/O resource-sharing across the Intel platforms, providing the
user with greater reliability, security and availability in networking and data-sharing.
The settings are Enable and Disable.

power settings. Select Disabled to disable power-saving settings. The options are Disable,
Energy Efficient, and Custom.
Config TDP
Select Enable to allow the user to configure the Thermal Design Power (TDP) settings for
the system. The TDP refers to the maximum amount of power allowed for running “real
applications” without triggering an overheating event. The options are Disable and Enable.
CPU P State Control
EIST (P-State)
EIST (Enhanced Intel SpeedStep Technology) allows the system to automatically adjust
processor voltage and core frequency in an effort to reduce power consumption and heat
dissipation. Please refer to Intel’s website for detailed information. The options are Disable
and Enable.
Turbo Mode
Select Enable for processor cores to run faster than the frequency specified by the manufacturer.
The options are Disable and Enable.
P-state Coordination
Use this item to configure the processor's P-State coordination settings. During a P-State, the
voltage and frequency of the processor will be reduced when it is in operation. This makes the
processor more energy efficient, resulting in further energy gains. The options are HW_ALL,
SW_ALL and SW-ANY.
CPU C State Control
Package C State limit
Use this item to set the limit on the C-State package register. The options are C0/1 state, C2
