MSI H81M-P33 Series User Manual page 29

▶ Adjusted DRAM Frequency
Shows the adjusted DRAM frequency. Read-only.
▶ DRAM Timing Mode [Auto]
Selects the memory timing mode.
[Auto] DRAM timings will be determined based on SPD (Serial Presence
Detect) of installed memory modules.
[Link] Allows user to configure the DRAM timing manually for all memory
channel.
[UnLink] Allows user to configure the DRAM timing manually for respective
memory channel.
▶ 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.)
▶ Memory Fast Boot [Auto]
Enables or disables the initiation and training for memory every booting.
[Auto] This setting will be configured automatically by BIOS.
[Enabled] Memory will completely imitate the archive of first initiation and
first training. After that, the memory will not be initialed and trained
when booting to accelerate the system booting time.
[Disabled] The memory will be initialed and trained every booting.
▶ DRAM Voltage [Auto]
Sets the memory voltage. If set to "Auto", BIOS will set memory voltage
automatically or you can set it manually.
▶ Spread Spectrum
This function reduces the EMI (Electromagnetic Interference) generated by
modulating clock generator pulses.
[Enabled] Enables the spread spectrum function to reduce the EMI
(Electromagnetic Interference) problem.
[Disabled] Enhances the overclocking ability of CPU Base clock.
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
