1. CPU socket
The motherboard comes with an AMD Socket AM4 designed for 3rd Gen AMD Ryzen™
Processors.
SOCKET AM4
The AM4 socket has a different pinout design. Ensure that you use a CPU designed for
the AM4 socket. The CPU ts in only one correct orientation. DO NOT force the CPU into
the socket to prevent bending the connectors on the socket and damaging the CPU!
Ensure that all power cables are unplugged before installing the CPU.

2. DIMM slots
The motherboard comes with Dual Inline Memory Modules (DIMM) slots designed for DDR4
(Double Data Rate 4) memory modules.
A DDR4 memory module is notched differently from a DDR, DDR2, or DDR3 module. DO
NOT install a DDR, DDR2, or DDR3 memory module to the DDR4 slot.

Chapter 1
Memory configurations
You may install 4 GB, 8 GB, 16 GB, and 32 GB unbuffered non-ECC DDR4 DIMMs into the
DIMM sockets.
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 configuration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.
• 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 efficient memory cooling system to support a full
memory load or overclocking condition.
• Always install the DIMMS with the same CAS Latency. For an optimum compatibility,
we recommend that you install memory modules of the same version or data code
(D/C) from the same vendor. Check with the vendor to get the correct memory
modules.
• Visit the ASUS website for the latest QVL.

• DO NOT connect the 4-pin power plug only. The motherboard may overheat under
heavy usage.
• Ensure to connect the 8-pin power plug, or connect both the 8-pin and 4-pin power
plugs.
• For a fully configured system, we recommend that you use a power supply unit
(PSU) that complies with ATX 12V Specification 2.0 (or later version) and provides a
minimum power of 350W.
• We recommend that you use a PSU with a higher power output when configuring a
system with more power-consuming devices. The system may become unstable or
may not boot up if the power is inadequate.
• If you want to use two or more high-end PCI Express x16 cards, use a PSU with
1000W power or above to ensure the system stability.

3.6 RAID configurations
The motherboard comes with the RaidXpert2 Configuration Utility that supports Volume,
RAIDABLE, RAID 0, RAID 1, and RAID 10 (depends on system licensing) configurations.
RAID definitions
RAID 0 (Data striping) optimizes two identical hard disk drives to read and write data in
parallel, interleaved stacks. Two hard disks perform the same work as a single drive but at a
sustained data transfer rate, double that of a single disk alone, thus improving data access
and storage. Use of two new identical hard disk drives is required for this setup.
RAID 1 (Data mirroring) copies and maintains an identical image of data from one drive to
a second drive. If one drive fails, the disk array management software directs all applications
to the surviving drive as it contains a complete copy of the data in the other drive. This RAID
configuration provides data protection and increases fault tolerance to the entire system.
Use two new drives or use an existing drive and a new drive for this setup. The new drive
must be of the same size or larger than the existing drive.
RAID 10 is data striping and data mirroring combined without parity (redundancy data)
having to be calculated and written. With the RAID 10 configuration you get all the benefits
of both RAID 0 and RAID 1 configurations. Use four new hard disk drives or use an existing
drive and three new drives for this setup.
For more information on configuring your RAID sets, please
refer to the RAID Configuration Guide which you can find at
https://www.asus.com/support, or by scanning the QR code.
