Intel AES-NI (When supported by the CPU)
Intel® AES instructions are a new set of instructions available beginning with
the the all new 2010 Intel® Core™ processor family based on the 32nm Intel®
microarchitecture. These instructions enable fast and secure data encryption and
decryption, using the Advanced Encryption Standard (AES). The options are
Dis-
abled and Enabled.
Simultaneous Multi-Threading (Available when supported by the CPU)
Set to Enabled to use the Hyper-Threading Technology, which will result in increased
CPU performance. The options are Disabled and
Enabled.
Active Processor Cores
Set to Enabled to use a processor's Second Core and beyond. (Please refer to
Intel's web site for more information.) The options are
All, 1 and 2.
Intel® EIST Technology
EIST (Enhanced Intel SpeedStep Technology) allows the system to automatically
adjust processor voltage and core frequency in an effort to reduce power consump-
tion and heat dissipation.
Please refer to Intel’s web site for detailed information.
The options are Disable (Disable GV3), and Enable (Enable GV3).
Intel® Turbo Boost (Available if Intel® EIST technology is Enabled)
This feature allows processor cores to run faster than marked frequency in specific
conditions. The options are Disabled and
Enabled.
C1E Support
Select Enabled to use the "Enhanced Halt State" feature. C1E significantly reduces
the CPU's power consumption by reducing the CPU's clock cycle and voltage during
a "Halt State." The options are Disabled and
Enabled.
Intel C-STATE Tech
If enabled, C-State is set by the system automatically to either C2, C3 or C4 state. The op-
tions are Disabled and
Enabled.
C-State package limit setting
If set to Auto, the AMI BIOS will automatically set the limit on the C-State package register.
The options are
Auto, C1, C3, C6 and C7.
C1 Auto Demotion
When enabled, the CPU will conditionally demote C3, C6 or C7 requests to C1 based on
un-core auto-demote information. The options are Disabled and
Enabled.
