▶ 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.
▶ DRAM Voltage [Auto]
Sets DRAM voltage. If set to "Auto", BIOS will set DRAM 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
your overclocked processor to lock up.
▶ Setup Software P-state limit
Enables or disables P-state limit which is a ceiling on the amount of performance
and power that a processor may utilize. Enabling this function will also decrease the
processor temperature.If set to "Auto", BIOS will set it automatically.
