Direct Cache Access (DCA)
Select Enable to use Intel DCA (Direct Cache Access) Technology to improve the
efficiency of data transferring and accessing. The options are Auto, Enable, and
Disable.
X2 APIC (Advanced Programmable Interrupt Controller)
Based on Intel's Hyper-Threading architecture, each logical processor (thread) is
assigned 256 APIC IDs (APIDs) in 8-bit bandwidth. When this feature is set to En-
able, the APIC ID will expand(X2) from 8 bits to 16 bits to provide 512 APIDs to
each thread to enhance CPU performance. The options are Disable and Enable.
AES-NI
Select Enable to use the Intel Advanced Encryption Standard (AES) New Instruc-
tions (NI) to ensure data security. The options are Enable and Disable.
Intel Virtualization Technology
Select Enable to use Intel Virtualization Technology for Direct I/O VT-d support
by reporting the I/O device assignments to the VMM (Virtual Machine Monitor)
through the DMAR ACPI tables. This feature offers fully-protected I/O resource
sharing across Intel platforms, providing greater reliability, security and availability
in networking and data-sharing. The options are Enable and Disable.

Power Technology
Select Energy Efficient to support power-saving mode. Select Custom to custom-
ize system power settings. Select Disable to disable power-saving settings. The
options are Disable, Energy Efficient, and Custom.
*If the option is set to Custom or Energy Efficient, the following items will display:
Energy Performance Tuning (Available when Power Technology is set to
Custom or Energy Efficient)
Select Enable for energy-performance tuning support to enhance energy ef-
ficiency, which might compromise system performance. The options are Enable
and Disable.

Energy Performance Bias Setting (Available when Power Technology is
set to Custom or Energy Efficient)
Use this feature to select an appropriate power setting and performance level
for the system. Select Performance to maximize system performance by using
maximum amount of power. Select Balanced Performance to downgrade system
performance a notch by using less power. Select Power to maximize power
saving, which may greatly compromise system performance as a result. Select
Balanced Power to downgrade power saving a notch and allow the system to
use more power to boost system performance. The options are Performance,
Balanced Performance, Balanced Power, and Power.
Energy Efficiency Turbo (Available when Power Technology is set to
Custom or Energy Efficient)
Select Enable for the system to operate at turbo mode with reduced power con-
sumption so that your machine can achieve maximum system performance with
the maximum power efficiency possible. The options are Enable and Disable.
*If the option is set to Custom, the following items will display:
CPU P State Control (Available when Power Technology
is set to Custom)
EIST (P-states)
EIST (Enhanced Intel SpeedStep Technology) allows the system to automatically
adjust processor voltage and core frequency to reduce power consumption and
heat dissipation. The options are Disable and Enable.
Turbo Mode
Select Enable to use the Turbo Mode to boost system performance. The options
are Enable and Disable.
P-state Coordination
This item is used to change the P-state (Power-Performance State) coordination
type. P-state is also known as "SpeedStep" for Intel processors. Select HW_ALL
to change the P-state coordination type for hardware components only. Select
SW_ALL to change the P-state coordination type for all software installed in the
system. Select SW_ANY to change the P-state coordination type for a software
program in the system. The options are HW_All, SW_ALL, and SW_ANY.
