(Note)
This item appears only if you install a memory module that supports this feature.
Extreme Memory Profile (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)
Profile1
Uses Profile 1 settings.
Profile2
(Note)
Uses Profile 2 settings.
System Memory Multiplier (SPD)
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
second is the memory frequency that is automatically adjusted according to the
BCLK Frequency(Mhz)
and
System Memory Multiplier
settings.
