MSI Z87-G55 manual Dram Timing Mode Auto Selects the memory timing mode

Chapter 3

▶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 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.

▶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.
