► Adjacent Cache Line Prefetch (Appears only when CPU supports)

The processor has a hardware adjacent cache line prefetch mechanism that automatically
fetches an extra 64-byte cache line whenever the processor requests for a 64-byte cache
line. This reduces cache latency by making the next cache line immediately available if the
processor requires it as well.
When enabled, the processor will retrieve the currently requested cache line, as well as the
subsequent cache line.
When disabled, the processor will only retrieve the currently requested cache line.

► Intel Virtualization Technology (Appears only when CPU supports)

Virtualization (i.e. Intel® Vanderpool Technology) allows a platform to run multiple
operating systems and applications in independent partitions or “containers.” One physical
compute system can function as multiple “virtual” systems. Vanderpool Technology can
help improve future virtualization solutions. This item will be displayed only when the CPU
is supporting this feature and the setting is used to enable/disable it.

► Power Technology

This item is used to enable or disable the power management features. Default value
is:[Energy Efficient].

► CPU C3 Report (Appears only when Set “Power Technology” to [Custom])

This item is used to enable or disable CPU C3 (ACPI C2) report to OS.

► CPU C6 Report (Appears only when Set “Power Technology” to [Custom])

This item is used to enable or disable CPU C6 (ACPI C3) report to OS.

► Package C State Limit (Appears only when Set “Power Technology” to [Custom])

This item is used to select the package c state limit.

► Local x2APIC

This item is used to enable or disable the "Local x2APIC". Some OSes do not support this.

► Active Processor Cores

This item is used to select the number of cores to enable in each processor package.

► EIST

You can select the EIST (Processor Power Management, PPM) through this item.

► Power Limit 1 Value (Watt)

This item is used to set the power limit 1 value. Default value is 95. you can change the

number from 0-500 by pressing “+/-” keys or input the number you want directly.

► Power Limit 2 Switch

This item is used to enable or disable the power limit 2 switch.

► Power Limit 2 Value

This item is used to set the power limit 1 value. Default value is 118. you can change the

number from 0-500 by pressing “+/-” keys or input the number you want directly.

Enhanced Intel SpeedStep® technology (EIST) allows the system to dynamically
adjust processor voltage and core frequency, which can result in decreased average
power consumption and decreased average heat production. There are some system
requirements must be met, including CPU, chipset, motherboard, BIOS and operation
system. Please refer to Intel website for more information.
