Hardware Prefetcher - Gigabyte GA-6UASL1 User Manual

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)
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
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.

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.
CPU Speed
The processor speed is the speed at which a microprocessor executes instructions. Clock speeds are
expressed in megahertz (MHz), with 1 MHz being equal to 1 million cycles per second. The faster the
clock, the more instructions the CPU can execute per second.
EMT64
