1.3 Central Processing Unit (CPU)
This motherboard comes with a surface mount Intel® Socket LGA1200
designed for 10th Gen Intel® Core™, Pentium®Gold and Celeron®
Processors.
Unplug all power cables before installing the CPU.
• Ensure that you install the correct CPU designed for the LGA1200 socket only. DO
NOT install a CPU designed for LGA1150, LGA1151, LGA1155 and LGA1156 sockets
on the LGA1200 socket.
• Upon purchase of the motherboard, ensure that the PnP cap is on the socket and
the socket contacts are not bent. Contact your retailer immediately if the PnP cap
is missing, or if you see any damage to the PnP cap/socket contacts/motherboard
components.
• Keep the cap after installing the motherboard. ASUS will process Return Merchandise
Authorization (RMA) requests only if the motherboard comes with the cap on the

1.4 System memory
This motherboard comes with two Double Data Rate 4 (DDR4) Dual Inline Memory Module
(DIMM) sockets. The gure illustrates the location of the DDR4 DIMM sockets:
Channel Sockets
Channel A DIMM_A1*
Channel B DIMM_B1*
DIMM_B1*
DIMM_A1*
• You may install varying memory sizes in Channel A and Channel B. The system
maps the total size of the lower-sized channel for the dual-channel conguration. Any
excess memory from the higher-sized channel is then mapped for single-channel
operation.
• Always install DIMMs with the same CAS latency. For optimal compatibility, we
recommend that you install memory modules of the same version or date code (D/C)
from the same vendor. Check with the retailer to get the correct memory modules.
• For 10th Gen Intel® processors, only Core™ i9/i7 CPUs support
2933/2800/2666/2400/2133 natively, others will run at the maximum transfer rate of
DDR4 2666MHz.
• The default memory operation frequency is dependent on its Serial Presence Detect
(SPD), which is the standard way of accessing information from a memory module.
Under the default state, some memory modules for overclocking may operate at a
lower frequency than the vendor-marked value.
• For system stability, use a more efcient memory cooling system to support a full
memory load (2 DIMMs).
• Refer to www.asus.com for the latest Memory QVL (Qualied Vendors List).

2.1 Knowing BIOS
The new ASUS UEFI BIOS is a Unied 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 specied.
BIOS (Basic Input and Output System) stores system hardware settings such as storage
device conguration, overclocking settings, advanced power management, and boot
device conguration 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 PB460MK.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.

After doing either of the three options, press <Delete> key to enter BIOS.
• 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>.
