Adjacent Cache Line Prefetch
Allows you to determine whether to enable the adjacent cache line prefetch mechanism that lets the
processor retrieve the requested cache line as well as the subsequent cache line. (Default: Auto)
& Extreme Memory Proile (X.M.P.)
(Note)
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.
Proile2
(Note)
Uses Proile 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 Ref Clock
Allows you to manually adjust the memory reference clock. (Default: Auto)
&
Memory Odd Ratio (100/133 or 200/266)
Enabled
allows Qclk to run in odd frequency. (Default: Auto)
&
Memory Frequency (MHz)
The irst 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 Proile (X.M.P.)
(Note)
, System Memory Multiplier, Memory Ref Clock,
Memory Odd Ratio (100/133 or 200/266), Memory Frequency(MHz)
The settings above are synchronous to those under the same items on the
Advanced Frequency Settings
menu.
&
Memory Boot Mode (Note)
Provides memory detection and training methods.
Auto Lets the BIOS automatically conigure this setting. (Default)

Chapter 1 for how to clear the CMOS values.)
Enable Fast Boot Skip memory detection and training in some speciic criteria for faster memory
boot.
Disable Fast Boot Detect and train memory at every single boot.
& Realtime Memory Timing
Allows you to ine-tune memory timings after the BIOS stage. (Default: Auto)
& Memory Enhancement Settings
Provides several memory performance enhancement settings: Normal (basic performance), Relax OC,
Enhanced Stability, and Enhanced Performance. (Default: Normal)
& Memory Timing Mode
Manual and Advanced Manual allows the Memory Multiplier Tweaker ,
Channel Interleaving
, Rank
Interleaving , and memory timing settings below to be conigurable. Options are: Auto (default), Manual,
Advanced Manual.
& Proile DDR Voltage
When using a non-XMP memory module or
Extreme Memory Proile (X.M.P.)
is set to Disabled , the value
is displayed according to your memory speciication. When Extreme Memory Proile (X.M.P.)
is set to
Proile1
or
Proile2
, the value is displayed according to the SPD data on the XMP memory.
(Note) This item is present only when you install a CPU and a memory module that support this feature.
