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 Conguration
Power Technology
Select Energy E󰀩cient to support power-saving mode. Select Custom to customize system
power settings. Select Disabled to disable power-saving settings. The options are Disable,
Energy E󰀩cient, and Custom.
Power Performance Tuning (Available when Power Technology is set to Custom)
Select BIOS to allow the system BIOS to congure 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 congure the optimal operation setting for your machine by achieving
the desired system performance level and energy saving (e󰀩ciency) 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 processor
operation. Select Maximum Power E󰀩ciency to minimize power use; however, system
performance will be impacted. The options are Maximum Performance, Performance,
Balanced Performance, Balanced Power, Power, and Max (Maximum) Power E󰀩cient.
CPU P State Control (Available when Power Technology is set to
Custom)
SpeedStep (P-States)
EIST (Enhanced Intel SpeedStep Technology) allows the system to automatically adjust
processor voltage and core frequency in an e󰀨ort to reduce power consumption and heat
