The new ASUS UEFI BIOS is a Unied Extensible Interface that complies with UEFI
architecture, offering a user-friendly interface that goes beyond the traditional keyboard-
only BIOS controls to enable a more exible and convenient mouse input. You can easily
navigate the new UEFI BIOS with the same smoothness as your operating system. The
term “BIOS” in this user manual refers to “UEFI BIOS” unless otherwise specied.
BIOS (Basic Input and Output System) stores system hardware settings such as storage
device conguration, overclocking settings, advanced power management, and boot
device conguration that are needed for system startup in the motherboard CMOS. In
normal circumstances, the default BIOS settings apply to most conditions to ensure
optimal performance. DO NOT change the default BIOS settings except in the following
circumstances:
• An error message appears on the screen during the system bootup and requests you
to run the BIOS Setup.
• You have installed a new system component that requires further BIOS settings or
update.
Inappropriate BIOS settings may result to instability or boot failure. We strongly
recommend that you change the BIOS settings only with the help of a trained service
personnel.
• When downloading or updating the BIOS le for your motherboard, rename it as
XXXXX.CAP. The name of the CAP le varies depending on models. Refer to the user
manual that came with your motherbord for the name.
• BIOS settings and options may vary due to different BIOS release versions. Please
refer to the latest BIOS version for settings and options.

settings to ensure system compatibility and stability. Select the Load Optimized
Defaults item under the Exit menu or press hotkey <F5>. See section 1.10 Exit
menu for details.
• If the system fails to boot after changing any BIOS setting, try to clear the CMOS
and reset the motherboard to the default value. See your motherboard manual for
information on how to erase the RTC RAM.
• The BIOS setup program does not support Bluetooth devices.

DIGI+ VRM
Changing the values in this menu may cause the system to become unstable! If this
happens, revert to the default settings.
VDDCR CPU Load-line Calibration
Load-line affects CPU power voltage. The CPU working voltage decreases
proportionally to CPU loading. Higher load-line calibration could get higher voltage and
good overclocking performance, but increases the CPU and VRM thermal conditions.
Select from levels 1 to 7 to adjust the load-line slope.
Conguration options [Auto] [Default] [Level 1] - [Level 7]
The actual performance boost may vary depending on your CPU specication.
DO NOT remove the thermal module. The thermal conditions should be monitored.
VDDCR CPU Current Capability
This item allows you to set the shut off current limit for external voltage regulator. A
higher setting will allow the voltage regulator to supply more current while a lower
setting will cause the voltage regulator to shut off the system when the supplied current
is higher than the set value.
Conguration options: [100%] [110%] [120%] [130%]
Congure higher values when overclocking or under a high CPU loading for extra power
support.
VDDCR CPU Switching Frequency
This item allows you to set a higher frequency for a quicker transient response speed.
Use the <+> or <-> to adjust the value. The values range from 200 to 350 with an
interval of 50.
DO NOT remove the thermal module. The thermal conditions should be monitored.
VDDCR CPU Power Phase Control
This item allows you to set the power phase control of the CPU.
[Manual] Phase number is adjusted by current(A) step.
[Optimized] Set to the ASUS optimized phase tuning prole.
[Extreme] Set to the full phase mode.
The following item appears only when the VDDCR CPU Power Phase Control is set to

22 PRIME/PRO/TUF GAMING X570 Series BIOS Manual
Manual Adjustment
This item allows you to set the response time, selecting [Regular] will
result in longer reaction times.
Conguration options: [Regular] [Medium] [Fast] [Ultra Fast]
VDDCR CPU Power Duty Control
This item allows you to set the duty cycle of each VRM phase based upon current and/
or temperature.
