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 irst 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.

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 conigure this setting. (Default)
Normal The BIOS automatically performs memory training. Please note that if the system
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
