(Note) This item is present only when you install a CPU and a memory module that support this feature.
& ExtremeMemoryProle(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)
Prole1 Uses Prole 1 settings.
Prole2
(Note)
Uses Prole 2 settings.
& AMDMemoryProle(A.M.P.)
(Note)
Allows the BIOS to read the SPD data on AMP memory module(s) to enhance memory performance when
enabled. (Default: Disabled)
& 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)
This value is automatically adjusted according to the BCLK/PCIe Clock Control and System Memory
Multiplier settings.

& ExtremeMemoryProle(X.M.P.)
(Note)
, System Memory Multiplier, Memory Frequency(MHz)
The settings above are synchronous to those under the same items on the Advanced Frequency Settings
menu.
& DRAM Timing Selectable
Quick and Expert allows the memory timing settings below to be congurable. Options are: Auto (default),
Quick, Expert.
& ProleDDRVoltage
When using a non-XMP memory module or ExtremeMemoryProle(X.M.P.) is set to Disabled, this item
will display as 1.50V. When ExtremeMemoryProle(X.M.P.) is set to Prole1 or Prole2, this item will
display the value based on the SPD data on the XMP memory.
& ProleVTTVoltage
The value displayed here is dependent on the CPU being used.
& 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. (Default: Enabled)
& 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. (Default: Enabled)
` Channel A/B Timing Settings
This sub-menu provides memory timing settings for each channel of memory. The respective timing setting
screens are congurable only when DRAM Timing Selectable is set to Quick or Expert. Note: Your system
may become unstable or fail to boot after you make changes on the memory timings. If this occurs, please reset
the board to default values by loading optimized defaults or clearing the CMOS values.
& CPU Core Control
Allows you to determine whether to manually enable/disable CPU cores. Automatic mode allows the BIOS
to enable all CPU cores (number of cores available depends on the CPU being used). (Default: Automatic
mode)
& APM
Enables or disables Application Power Management. (Default: Enabled)
