& 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 Profile (X.M.P.)
Allows the BIOS to read the SPD data on XMP memory module(s) to enhance memory performance when
enabled.
Disables this function. (Default)
Disabled
Uses Profile 1 settings.
Profile1
Uses Profile 2 settings.
(Note)
Profile2
& 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 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.)
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 configure this setting. (Default)
The BIOS automatically performs memory training. Please note that if the system
Normal
becomes unstable or unbootable, try to clear the CMOS values and reset the board
to default values. (Refer to the introductions of the battery/clear CMOS jumper in
Chapter 1 for how to clear the CMOS values.)
S kip memory detection and training in some specific criteria for faster memory
Enable Fast Boot
boot.
Disable Fast Boot Detect and train memory at every single boot.
& Realtime Memory Timing
Allows you to fine-tune memory timings after the BIOS stage. (Default: Auto)
& Memory Enhancement Settings
Provides several memory performance enhancement settings: Relax OC, Enhanced Stability, Normal,
Enhanced Performance, High Frequency, High Density and DDR-4500+. (Default: Auto)
& Memory Timing Mode
Manual and Advanced Manual allows the Memory Multiplier Tweaker, 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, the value
is displayed according to your memory specification. When Extreme Memory Profile (X.M.P.) is set to
Profile1 or Profile2, 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.
