Direct Cache Access (DCA)
This feature enables/disables Direct Cache Access (DCA), which is a
system level protocol in a multiprocessor system to improve I/O network
performance. Options include either Disable, Enable or
Auto .
Intel Virtualization
Technology
When this feature is enabled, a VMM can utilize the additional hardware
capabilities provided by Vanderpool Technology. Options include either
Disable or
Enable .
 Advanced Power
Management Configuration
This submenu displays and provides the option to change the Power
Management Settings for your system.
EIST (P-States)
EIST allows the processor to dynamically adjust frequency and voltage
based upon power versus performance needs. Options include either
Disable or
Enable .
 CPU P State Control
This submenu controls CPU frequency for your system. P-State is a
processor operational state that reduces the processor's voltage and
frequency to enhance CPU energy efficiency.
P State Domain
Use this feature to specify the P State Domain for your system. Options
include
All or One.
P-state Coordination
Use this feature to determine how ACPI-aware operating systems
coordinates P-State transitions between logical processors. HW_All is
recommended for E5-2600 v3/v4. Options include
HW_ALL , SW_ALL and
SW_ANY.
Energy Efficient
P-State This feature allows you to enable/disable the energy efficient P-state
feature. Options include either
Enable or Disable.
Boot Performance
Mode This feature selects the performance state the BIOS will set before OS
handoff. Options include
Max Performance or Max Efficient.
Turbo Mode
Turbo Mode opportunistically and automatically allows the processor cores
to run faster the marked frequency if the physical processor is operating
below power, temperature and current specification limits. Options include
either
Enable or Disable.
 CPU HWPM State
Control
This submenu allows you to control CPU HWPM state control
configuration.
Enable CPU HWPM
This feature enables CPU HWPM for better energy performance of the
CPU. Options include either Enable or
Disable .
Enable CPU
Autonomous Cstate
This feature enables CPU Autonomous Cstate, which allows the CPU to
convert a HALT instruction to MWAIT. Options include either Enable or
Disable .
 CPU C State Control This submenu provides features that allow you to control CPU Idle states.
CPU C State
This feature enables the enhanced Cx state of the CPU, and takes effect
after reboot. Options include either
Enable or Disable.
Package C State
Limit
This feature limits the lowest package level C-State to the processors.
Lower package C-State gives the system lower processor power
consumption upon idle. Options include C0/C1 state, C2 state, C6
(Non-retention) state,
C6 (Retention) state and No Limit
