[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.)
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.
DRAM Voltage [Auto]
Sets the value for appointed voltage related to memory. If set to "Auto", BIOS will set
the voltage automatically or you can set it manually.
CPU Memory Changed Detect [Enabled]
Enables or disables the system to issue a warning message during boot when the
CPU or memory has been replaced.
[Enabled]
The system will issue a warning message during boot and than
needs to load the default settings for new devices.
[Disabled] Disables this function and keeps the current BIOS settings.
OC Retry Count
When overclocking has failed, setting this item as [1,3] will allow system to reboot
1/ 3 times with the same overclocked configuration. If overclocking has failed every
time, the system will restore the defaults.
Overclocking Profiles
Overclocking Profiles management. Press <Enter> to enter the sub-menu.
