(Note)
,SystemMemoryMultiplier,MemoryFrequency(MHz)
The settings above are synchronous to those under the same items on the Advanced Frequency Set-
tings menu.
&
Performance Enhance
Allows the system to operate at three different performance levels.

Normal Lets the system operate at its basic performance level.

Turbo Lets the system operate at its good performance level. (Default)

Extreme Lets the system operate at its best performance level.
&
DRAM Timing Selectable
Quick and Expert allows the Channel Interleaving, Rank Interleaving, and 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.
&
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 au-
tomatically congure this setting. (Default: Auto)
&
Rank Interleaving
Enables or disables memory rank interleaving. Enabled allows the system to simultaneously access dif-
ferent ranks of the memory to increase memory performance and stability. Auto lets the BIOS automati-
cally congure this setting. (Default: Auto)
&
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.
&
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 rst memory frequency value is the normal operating frequency of the memory being used; the sec-
ond is the memory frequency that is automatically adjusted according to the System Memory Multiplier
settings.
(Note) This item is present only when you install a CPU and a memory module that support this feature.
`
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.
