▶ Intel Extreme Memory Profile (XMP) [Disabled]
XMP is the overclocking technology by memory module. This item will be available
when you install the memory modules that support XMP technology. When the XMP
is Enabled, the AMP will be forced to be disabled.
[Disabled]
[Profile 1]
[Profile 2]
▶ DRAM Timing Mode [Auto]
Selects the memory timing mode.
[Auto]
[Link]
[UnLink]
▶ Advanced DRAM Configuration
Press <Enter> to enter the sub-menu. This sub-menu will be activated after setting
[Link] or [Unlink] in "DRAM Timing Mode". User can set the memory timing for each
memory channel. The system may become unstable or unbootable after changing
memory timing. If it occurs, please clear the CMOS data and restore the default
settings. (Refer to the Clear CMOS jumper/ button section to clear the CMOS data,
and enter the BIOS to load the default settings.
▶ DRAM Voltage [Auto]
Sets DRAM voltage. If set to "Auto", BIOS will set DRAM voltage automatically or
you can set it manually.
▶ Spread Spectrum [Enabled]
This function reduces the EMI (Electromagnetic Interference) generated by
modulating clock generator pulses.
[Enabled]
[Disabled]
Important
• If you do not have any EMI problem, leave the setting at [Disabled] for optimal
system stability and performance. But if you are plagued by EMI, select the value
of Spread Spectrum for EMI reduction.
• The greater the Spread Spectrum value is, the greater the EMI is reduced, and
the system will become less stable. For the most suitable Spread Spectrum value,
please consult your local EMI regulation.
• Remember to disable Spread Spectrum if you are overclocking because even a
slight jitter can introduce a temporary boost in clock speed which may just cause
your overclocked processor to lock up.
Disables this function.
Uses profile1 over-clocking settings of installed XMP memory
module.
Uses profile2 over-clocking settings of installed XMP memory
module.
DRAM timings will be determined based on SPD (Serial Presence
Detect) of installed memory modules.
Allows user to configure the DRAM timing manually for all memory
channel.
Allows user to configure the DRAM timing manually for respective
memory channel.
Enables the spread spectrum function to reduce the EMI
(Electromagnetic Interference) problem.
Enhances the overclocking ability of CPU Base clock.
