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 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)

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 memory module that supports 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.

&

Channel Interleaving

Enables or disables memory channel interleaving. 

Enabled

 allows the system to simultaneously access 

different channels of the memory to increase memory performance and stability. 

Auto

 lets the BIOS 

automatically configure this setting. (Default: Auto)

&

Rank Interleaving

Enables or disables memory rank interleaving. 

Enabled

 allows the system to simultaneously access different 

ranks of the memory to increase memory performance and stability. 

Auto

 lets the BIOS automatically 

configure this setting. (Default: Auto)
