CPU Information

This category includes all the information of CPU Speed and supported 64-Bit information.

Hyper Threading

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.
Options available: Enabled/Disabled. Default setting is Enabled.
Active Processor Cores
(Note)
Allows you to determine whether to enable all CPU cores.
Options available: All/1/2/3. Default setting is All.
Limit CPUID Maximum
Allows you to determine whether to enable CLimit CPUID Maximum function
Options available: Enabled/Disabled. Default setting is Disabled.

Execute Disable Bit

When this item enabled, the processor prevents the execution of code in data-only memory pages. This
provides some protection against buffer overflow attacks.
Options available: Enabled/Disabled. Default setting is Enabled.

Hardware Prefetcher

Select whether to enable the speculative prefetch unit of the processor.
Options available: Enabled/Disabled. Default setting is Enabled.
Adjacent Cache Line Prefetch
When enabled, cache lines are fetched in pairs. When disabled, only the required cache line is fetched.
Options available: Enabled/Disabled. Default setting is Enabled.

Intel Virtualization Technology

Select whether to enable the Intel Virtualization Technology function. VT allows a single platform to run
multiple operating systems in independent partitions.
Options available: Enabled/Disabled. Default setting is Disabled.

Power Technology

Determine the CPU power saving type.
Options available:Disabled/Custom/Energy Efficient. Default setting is Custom.
EIST (Enhanced Intel SpeedStep Technology)
Conventional Intel SpeedStep Technology switches both voltage and frequency in tandem between high
and low levels in response to processor load.
Options available: Enabled/Disabled. Default setting is Enabled.
Turbo Mode
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.
Options available: Enabled/Disabled. Default setting is Enabled.
P-State Coordination
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
