& 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
(Note) Uses Profile 2 settings.
Profile2
& 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 sec-
ond is the memory frequency that is automatically adjusted according to the System Memory Multiplier
settings.
` Advanced Memory Settings
& Extreme Memory Profile (X.M.P.)
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.
Lets the system operate at its basic performance level.
Normal
Lets the system operate at its good performance level. (Default)
Turbo
Lets the system operate at its best performance level.
Extreme
& DRAM Timing Selectable
Quick and Expert allows the Channel Interleaving, Rank Interleaving, and memory timing settings
below to be configurable. Options are: Auto (default), Quick, Expert.
& Profile DDR Voltage
When using a non-XMP memory module or Extreme Memory Profile (X.M.P.) is set to Disabled, this
item will display as 1.50V. When Extreme Memory Profile (X.M.P.) is set to Profile1 or Profile2, 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 configure 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 configure this setting. (Default: Auto)
` Channel A/B Timing Settings
This sub-menu provides memory timing settings for each channel of memory. The respective timing setting
screens are configurable 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.
(Note) This item is present only when you install a CPU and a memory module that support this feature.
