C3 State Support
(Note 1)
Allows you to determine whether to let the CPU enter C3 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 state is a more enhanced power-saving state than C1. Auto lets the BIOS automatically configure
this setting. (Default: Auto)
&
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.
`
Advanced Memory Settings
&
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.
