Intel Hyper Threading Technology; Intel Virtualization Technology - Gigabyte GA-6UASV3 User Manual

Intel Hyper Threading Technology

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.

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 Enabled.
Intel EIST Support (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.
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
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.
Options available: HW_ALL/SW_ALL/SW_ANY. Default setting is HW_ALL.
Intel Turbo Boost Technology
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.
C1E Support (CPU Enhanced Halt)
(Note)
Enables or disables Intel CPU Enhanced Halt (C1E) function, a CPU power-saving function in system
halt state. When enabled, the CPU core frequency and voltage will be reduced during system halt state
to decrease power consumption.
Options available: Enabled/Disabled. Default setting is Enabled.
CPU C3/C6 Support
(Note)
Allows you to determine whether to let the CPU enter C3/C6 mode in system halt state. When enabled,
the CPU core frequency and voltage will be reduced during system halt state to decrease power con-
sumption. The C3/C6 state is a more enhanced power-saving state than C1. Auto lets the BIOS auto-
matically configure this setting.
Options available for CPU C3 Report: ACPI C2/ACPI C3/Disabled. Default setting is ACPI C2.
Options available for CPU C6 Report: Enabled/Disabled. Default setting is Enabled.
Package C State Limit
Configure state for the C-State package limit.
Options available: C0/C1/C6/C7/No Limit. Default setting is No Limit.
