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.
&
Profile DDR Voltage
When using a non-XMP memory module or Extreme Memory Pro fi le (X.M.P.) is set to Disabled , this item
will display as 1.50V . When Extreme Memory Pro fi le (X.M.P.) is set to Pro fi le1 or Pro fi le2 , 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)
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.
