DCU IP Prefetcher
If set to Enable, the IP prefetcher in the DCU (Data Cache Unit) will prefetch IP
addresses to improve network connectivity and system performance. The options
are Enable and Disable.
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 for CPU performance enhancement. 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 and integrity. The options are Enable and Disable.
Intel Virtualization Technology
Select Enable to use Intel Virtualization Technology support for Direct I/O VT-d sup-
port 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.
Advanced Power Management Configuration
Advanced Power Management Configuration
Power Technology
Select Energy Efficient to support power-saving mode. Select Custom to custom-
ize system power settings. Select Disabled 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 efficiency,
which might compromise system performance. The options are Enable and Disable.
7-8
Energy Performance BIAS Setting (Available when Power Technology is set
to Custom or Energy Efficient)
Use this feature to select an appropriate fan setting to achieve maximum system
performance (with maximum cooling) or maximum energy efficiency with maximum
power saving). The fan speeds are controlled by the firmware management via
IPMI interface. 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 Disable and Enable.
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.
CPU C State Control (Available when Power Technology is
set to Custom)
Package C State limit
Use this item to set the limit on the C-State package register. The options are
C0/C1 state, C2 state, C6 (non Retention) state, and C6 (Retention) state.
