▶ 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. ▶ 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. [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. [Options: Auto, +12.5%, +25%, +37.5%, +50%, +62.5%, +75%, +87.5%, +100%] ▶ 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. ▶ CPU Over Current Protection [Auto] Sets the current limit for CPU over-current protection. If set to "Auto", BIOS will configure this setting automatically. Higher percentage provides less protection and may damage the system. ▶ Phase Over Current Protection [Enabled] Enables or disables the phase over-current protection. [Enabled] Sets the current limit on the phase for over-current protection. [Disabled] Disables this function. Chapter 3 BOIS Setup 3-20

BOIS Setup
DRAM Training Configuration
Press <Enter> 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 <Enter> to enter the sub-menu. Controls the digital powers related to CPU
PWM.
