&
CPU Core Enabled
(Note 1)
Allows you to determine the number of CPU cores you want to enable. Auto lets the BIOS automatically
conigure this setting. (Default: Auto)
&
Hyper-Threading Technology
Allows you to determine whether to enable Hyper-Threading technology when using an Intel CPU that
supports this function. This feature only works for operating systems that support multi-processor mode.
Auto lets the BIOS automatically conigure this setting. (Default: Auto)
&
CPU Enhanced Halt (C1E)
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. Auto lets the BIOS automatically conigure this setting. (Default: Auto)
&
C3/C6 State 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 consumption.
The C3/C6 state is a more enhanced power-saving state than C1. Auto lets the BIOS automatically conigure
this setting. (Default: Auto)
&
CPU Thermal Monitor
Enables or disables Intel CPU Thermal Monitor function, a CPU overheating protection function. When
enabled, the CPU core frequency and voltage will be reduced when the CPU is overheated. Auto lets the
BIOS automatically conigure this setting. (Default: Auto)
&
CPU EIST Function
(Note 1)
Enables or disables Enhanced Intel SpeedStep Technology (EIST). Depending on CPU loading, Intel EIST
technology can dynamically and effectively lower the CPU voltage and core frequency to decrease average
power consumption and heat production. Auto lets the BIOS automatically conigure this setting. (Default:
Auto)
&
Bi-Directional PROCHOT
Auto Lets BIOS automatically conigure this setting. (Default)


Enabled When the CPU or chipset detects that an overheating is occurring, PROCHOT signals
will be emitted to lower CPU performance to decrease heat production.

Disabled Only allows the CPU to detect whether an overheating is occurring to emit PROCHOT
signals.
Extreme Memory Proile (X.M.P.)
&
Allows the BIOS to read the SPD data on XMP memory module(s) to enhance memory performance when
enabled.

Disabled Disables this function. (Default)
Proile1 Uses Proile 1 settings.

Uses Proile 2 settings.

&
System Memory Multiplier (SPD)
Allows you to set the system memory multiplier. Auto sets memory multiplier according to memory SPD
data. (Default: Auto)
