4 System BIOS 64
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 consumption and heat
dissipation. Please refer to Intel’s web site for detailed information.
The options are Disable (Disable GV3) and Enable (Enable GV3).
C1E Support: Select Enabled to use the feature of Enhanced Halt State.
C1E significantly reduces the CPU's power consumption by reducing
the CPU's clock cycle and voltage during a Halt State.
Intel C-STATE Tech: If Enabled, C-State is set by the system
automatically to either C2, C3 or C4.
C-State package limit setting: If set to Auto, the BIOS will automatically
set the limit on the C-State package register.
C1 Auto Demotion: When Enabled, the CPU will conditionally demote
C3, C6 or C7 requests to C1 based on un-core auto-demote
information.
ACPI T State: Select Enabled to report processor throttling in ACPI.
C3 Auto Demotion: When Enabled, the CPU will conditionally demote
C6 or C7 requests to C3 based on un-core auto-demote information.
Clock Spread Spectrum: Select Enable to use the feature of Clock
Spectrum, which will allow the BIOS to monitor and attempt to reduce
the level of Electromagnetic Interference caused by the components
whenever needed.
DCA Technology: Uses Intel's DCA (Direct Cache Access) Technology to
enhance data transfer effi ciency.
DCA Prefetch Delay: Used with TOE components to prefetch data in
order to shorten execution cycles and maximize data processing effi
ciency. Prefetching too frequently can saturate the cache directory and
delay necessary cache accesses. This feature reduces or increases the
frequency the system prefetches data.
Advanced Chipset Control
The items included in the Advanced Settings submenu are listed below:
NorthBridge Chipset Configuration
QPI Links Speed: This feature selects QPI data transfer speed.
