BIOS Setup
fAdjacent Cache Line Prefetch [Enabled]
Enables or disables the CPU hardware prefetcher (MLC Spatial prefetcher).
[Enabled] Enables adjacent cache line prefetching for reducing the cache
latency time and tuning the performance to the specific application.
[Disabled] Enables the requested cache line only.
fCPU AES Instructions [Enabled]
Enables or disables the CPU AES (Advanced Encryption Standard-New
Instructions) support. This item appears when a CPU supports this function.
fIntel Adaptive Thermal Monitor [Enabled]
Enables or disables the Intel adaptive thermal monitor function to protect the CPU
from overheating.
[Enabled] Throttles down the CPU core clock speed when the CPU is over the
adaptive temperature.
[Disabled] Disables this function.
fIntel C-State [Auto]
Enables or disables the Intel C-state. C-state is a processor power management
technology defined by ACPI.
[Auto] This setting will be configured automatically by BIOS.
[Enabled] Detects the idle state of system and reduce CPU power consumption
accordingly.
[Disabled] Disable this function.
fC1E Support [Disabled]
Enables or disables the C1E function for power-saving in halt state. This item
appears when Intel C-State is enabled.
[Enabled] Enables C1E function to reduce the CPU frequency and voltage for
power-saving in halt state.
[Disabled] Disables this function.
fPackage C State limit [Auto]
This item allows you to select a CPU C-state level for power-saving when system is
idle. The options of C-state depend on the installed CPU. This item appears when
Intel C-State is enabled.
fCFG Lock [Enabled]
Lock or un-lock the MSR 0xE2[15], CFG lock bit.
[Enabled] Locks the CFG lock bit.
[Disabled] Un-locks the CFG lock bit.
fEIST [Enabled]
Enables or disables the Enhanced Intel
®
SpeedStep Technology. This item will
appear when OC Explore Mode is set to Normal.
[Enabled] Enables the EIST to adjust CPU voltage and core frequency
dynamically. It can decrease average power consumption and
average heat production.
[Disabled] Disables EIST.
