C6/C7 State Support 

(Note 1)

Allows you to determine whether to let the CPU enter C6/C7 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 C6/C7 state is a more enhanced power-saving state than C3. 

Auto

 lets the BIOS automatically configure 

this setting. (Default: Auto)

&

CPU Thermal Monitor 

(Note 1)

Enables or disables Intel

®

 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 configure this setting. (Default: Auto)

&

CPU EIST Function 

(Note 1)

Enables or disables Enhanced Intel

®

 Speed Step 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 configure this setting. 

(Default: Auto)

&

Extreme Memory Profile (X.M.P.) 

(Note 2)

Allows the BIOS to read the SPD data on XMP memory module(s) to enhance memory performance when 

enabled.

Disabled   

Disables this function. (Default)

Profile1   

Uses Profile 1 settings.

Profile2 

(Note 2)

  Uses Profile 2 settings.

&

System Memory Multiplier

Allows you to set the system memory multiplier. 

Auto

 sets memory multiplier according to memory SPD 

data. (Default: Auto)

&

Memory Frequency (MHz)

The first memory frequency value is the normal operating frequency of the memory being used; the second 

is the memory frequency that is automatically adjusted according to the 

System Memory Multiplier

 settings.

(Note 1)  This item is present only when you install a CPU that supports this feature. For more information about 

Intel

®

 CPUs' unique features, please visit Intel's website.

(Note 2)  This item is present only when you install a CPU and a memory module that support this feature.

&

 Extreme Memory Profile (X.M.P.) 

(Note 2)

, System Memory Multiplier, Memory 

Frequency(MHz)

The settings above are synchronous to those under the same items on the 

Advanced Frequency Settings

menu.

&

Memory Enhancement Settings

 Provides three different memory performance enhancement settings: Normal (basic performance), Enhanced 

Stability, and Enhanced Performance. (Default: Normal)

&

Memory Timing Mode 

Manual

 and 

Advanced Manual

 allows the 

Channel Interleaving

, 

Rank Interleaving

, and memory timing 

settings below to be configurable. Options are: Auto (default), Manual, Advanced Manual.

&

Profile DDR Voltage

When using a non-XMP memory module or 

Extreme Memory Profile (X.M.P.)

 is set to 

Disabled

, this item 

will display as 

1.50V

. When 

Extreme Memory Profile (X.M.P.)

 is set to 

Profile1

 or 

Profile2

, this item will 

display the value based on the SPD data on the XMP memory.
