BIOS Setup
1.1 Knowing BIOS
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, rename it as SX470FG.CAP for this
motherboard.
• BIOS settings and options may vary due to different BIOS release versions. Please
refer to the latest BIOS version for settings and options.

include navigation keys and brief onscreen help to guide you in using the BIOS Setup
program.
Entering BIOS at startup
To enter BIOS Setup at startup, press <Delete> or <F2> during the Power-On Self Test
(POST). If you do not press <Delete> or <F2>, POST continues with its routines.
Entering BIOS Setup after POST
To enter BIOS Setup after POST:
• Press <Ctrl>+<Alt>+<Delete> simultaneously.
• Press the reset button on the system chassis.
• Press the power button to turn the system off then back on. Do this option only if you
failed to enter BIOS Setup using the rst two options.
After doing either of the three options, press <Delete> key to enter BIOS.
• The BIOS setup screens shown in this section are for reference purposes only, and
may not exactly match what you see on your screen.
• Ensure that a USB mouse is connected to your motherboard if you want to use the
mouse to control the BIOS setup program.
• If the system becomes unstable after changing any BIOS setting, load the default
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 section 1.1.7 Headers in your user
manual for information on how to erase the RTC RAM.
• The BIOS setup program does not support Bluetooth devices.

TDP Conguration
This item appears depending on the APU type installed.
Target TDP
Allows you to manually set up a TDP (Thermal Design Power) value. The processor
will run within the specied TDP to constrain power consumption.
DIGI+ VRM
VDDCR CPU Load-line Calibration
Load-line is dened by Intel® specication and 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 8 to adjust the load-line slope.
Conguration options [Auto] [Level 1] - [Level 8]
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

Status denition:
• Frozen. The frozen state is the result of a BIOS protective measure. The BIOS
guards drives that do not have password protection by freezing them prior to booting.
If the drive is frozen, a power off or hard reset of your PC must be performed to
proceed with the Secure Erase.
• Locked. SSDs might be locked if the Secure Erase process is either incomplete
or was stopped. This may be due to a third party software that uses a different
password dened by ASUS. You have to unlock the SSD in the software before
proceeding with Secure Erase.
