Description
The Intel Hyper Threading Technology allows a single
processor to execute two or more separate threads
concurrently. When hyper-threading is enabled,
multi-threaded software applications can execute their
threads, thereby improving performance.
Setting the active processor core.
When this item enabled, the processor prevents the
execution of code in data-only memory pages. This
provides some protection against buffer overflow
attacks.
Select whether to enable the Intel Virtualization
Technology function. VT allows a single platform to run
multiple operating systems in independent partitions.
Intel Advanced Encryption Standard Instructions
(AES-NI), is a symmetric block cipher that
encrypts/decrypts data through several rounds. AES-NI
can be used to accelerate the performance of an
implementation of AES by 3 to 10x over a completely
software implementation.
Conventional Intel SpeedStep Technology switches both
voltage and frequency in tandem between high and low
levels in response to processor load.
In HW_ALL mode, the processor hardware is
responsible for coordinating the P-state among logical
processors dependencies. The OS is responsible for
keeping the P-state request up to date on all logical
processors.
In SW_ALL mode, the OS Power Manager is
responsible for coordinating the P-state among logical
processors with dependencies and must initiate the
transition on all of those Logical Processors.
In SW_ANY mode, the OS Power Manager is
responsible for coordinating the P-state among logical
processors with dependencies and may initiate the
transition on any of those Logical Processors.
When this feature is enabled, the processor can
dynamically overclock one or two of its four processing
cores to improve performance with applications that are
not multi-threaded or optimized for quad-core
processors.
Select whether to enable the C1 Enhanced mode for the
processor. If enabled, all logical processors in a physical
processor will run in a C1 state.
