▶DRAM Training Configuration*
Press to enter the sub-menu. Enables or disables the various training ways of
DRAM. The system may become unstable or unbootable after changing these items in
this sub-menu. 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.

▶DigitALL Power
Press to enter the sub-menu. Controls the digital powers related to CPU PWM.
▶VR 12VIN OCP Expander [Auto]
Expands the limitation of VR Over Current Protection with 12V input voltage. The
higher expanding value indicates less protection. Therefore, please adjust the
current carefully if needed, or it may damage the CPU/ VR MOS. If set to "Auto",
BIOS will configure this setting automatically.
▶CPU Phase Control [Auto]
Controls PWM phase proportionally to the CPU loading. If set to "Auto", BIOS will
optimize the CPU PWM phase automatically.
[Auto] This setting will be configured automatically by BIOS.
[Normal] Sets the normal power phase profile for CPU, it could provide a stable
system proformance and effective power-saving capability.
[Optimized] Sets the optimum power phase profile for CPU, it could provide the
system with an optimum power-saving capability.
[Disabled] Disables the PWM power phase switching feature.
▶CPU Vdroop Offset Control [Auto]
Sets a percentage of offset voltage for CPU vdroop. If set to "Auto", BIOS will
configure this setting automatically.
▶CPU Over Voltage Protection [Auto]
Sets the voltage limit for CPU over-voltage protection. If set to "Auto", BIOS will
configure this setting automatically. Higher voltage provides less protection and
may damage the system.
▶CPU Under Voltage Protection [Auto]
Sets the voltage limit for CPU under-voltage protection. If set to "Auto", BIOS will
configure this setting automatically. Higher voltage provides less protection and may
damage the system.
