DCU IP Prefetcher
This feature allows the system to use the sequential load history, which is based on the
instruction pointer of previous loads, to determine whether the system will prefetch additional
lines. The options are
Enable and Disable.
LLC Prefetch
If this feature is set to Enable, LLC (hardware cache) prefetching on all threads will be
supported. The options are
Disable
and Enable.
Extended APIC (Extended Advanced Programmable Interrupt Controller)
Based on the Intel Hyper-Threading technology, each logical processor (thread) is assigned
256 APIC IDs (APIDs) in 8-bit bandwidth. When this feature is set to Enable, the APIC ID
will be expanded 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 Instructions (NI) to
ensure data security. The options are
Enable and Disable.

Advanced Power Management Configuration
Power Technology
Select Energy Efficient to support power-saving mode. Select Custom to customize system
power settings. Select Disabled to disable power-saving settings. The options are Disable,
Energy Efficient
, and Custom.
Power Performance Tuning (Available when "Power Technology" is set to Custom)
Select BIOS to allow the system BIOS to configure the Power-Performance Tuning Bias
setting. The options are BIOS Controls EPB and OS Controls EPB .
ENERGY_PERF_BIAS_CFG Mode (ENERGY PERFORMANCE BIAS
CONFIGURATION Mode) (Available when "Power Performance Tuning" is set to
BIOS Controls EPB)
Use this feature to configure the optimal operation setting for your machine by achieving
the desired system performance level and energy saving (efficiency) level at the same time.
Select Maximum Performance to maximize system performance to its highest potential;
however, this may consume maximal amount of power as energy is needed to fuel the
processor frequency. (In other words, system performance is gained at the cost of system
power efficiency, depending on the workload.) Select Maximum Power Efficiency to minimize
power use; however, system performance will be greatly impacted as the result of power
saving. The options are Maximum Performance, Performance,
Balanced Performance ,
Balanced Power, Power, and Max (Maximum) Power Efficient.
