Introduction to the AM4 CPU
The surface of the AM4 CPU has a
yellow triangle to assist in correctly
lining up the CPU for motherboard
placement. The yellow triangle is
the Pin 1 indicator.

Distance from the center of the
CPU to the nearest DIMM slot.
⚠
Important
∙
When changing the processor, the system configuration could be cleared and reset
BIOS to default values, due to the AM4 processor’s architecture.
∙
Always unplug the power cord from the power outlet before installing or removing
the CPU.
∙
When installing a CPU, always remember to install a CPU heatsink. A CPU heatsink
is necessary to prevent overheating and maintain system stability.
∙
Confirm that the CPU heatsink has formed a tight seal with the CPU before booting
your system.
∙
Overheating can seriously damage the CPU and motherboard. Always make sure
the cooling fans work properly to protect the CPU from overheating. Be sure to apply
an even layer of thermal paste (or thermal tape) between the CPU and the heatsink to
enhance heat dissipation.
∙
If you purchased a separate CPU and heatsink/ cooler, Please refer to the
documentation in the heatsink/ cooler package for more details about installation.
∙
This motherboard is designed to support overclocking. Before attempting to
overclock, please make sure that all other system components can tolerate
overclocking. Any attempt to operate beyond product specifications is not
recommended. MSI® does not guarantee the damages or risks caused by inadequate
operation beyond product specifications.

Memory module installation recommendation
⚠
Important
∙
Always insert memory modules in the DIMMA2 slot first.
∙
Due to chipset resource usage, the available capacity of memory will be a little less
than the amount of installed.
∙
Based on CPU specification, the Memory DIMM voltage below 1.35V is suggested to
protect the CPU.
∙
To ensure system stability for Dual channel mode, memory modules must be of the
same type, number and density.
∙
Some memory modules may operate at a lower frequency than the marked value
when overclocking due to the memory frequency operates dependent on its Serial
Presence Detect (SPD). Go to BIOS and find the DRAM Frequency to set the memory
frequency if you want to operate the memory at the marked or at a higher frequency.
∙
It is recommended to use a more efficient memory cooling system for full DIMMs
installation or overclocking.
∙
The stability and compatibility of installed memory module depend on installed CPU
and devices when overclocking.
∙
Please refer www.msi.com for more information on compatible memory.

PCI_E1~4: PCIe Expansion Slots
⚠
Important
∙
If you install a large and heavy graphics card, you need to use a tool such as MSI
Gaming Series Graphics Card Bolster to support its weight to prevent deformation of
the slot.
∙
For a single PCIe x16 expansion card installation with optimum performance, using
the PCI_E1 slot is recommended.
∙
When adding or removing expansion cards, always turn off the power supply and
unplug the power supply power cable from the power outlet. Read the expansion
card’s documentation to check for any necessary additional hardware or software
changes.
∙
When installing devices in M.2_2, PCI_E2 & PCI_E3 slots at the same time, PCI_E3
slot will be unavailable, and M2_2 slot only supports PCIe x2.

UEFI BIOS
UEFI BIOS
MSI UEFI BIOS is compatible with UEFI (Unified Extensible Firmware Interface)
architecture. UEFI has many new functions and advantages that traditional BIOS
cannot achieve, and it will completely replace BIOS in the future. The MSI UEFI
BIOS uses UEFI as the default boot mode to take full advantage of the new chipset’s
capabilities. However, it still has a CSM (Compatibility Support Module) mode to be
compatible with older devices. That allows you to replace legacy devices with UEFI
compatible devices during the transition.
⚠
Important
The term BIOS in this user guide refers to UEFI BIOS unless otherwise noted.
UEFI advantages
∙Fast booting - UEFI can directly boot the operating system and save the BIOS self-
test process. And also eliminates the time to switch to CSM mode during POST.
∙Supports for hard drive partitions larger than 2 TB.
∙Supports more than 4 primary partitions with a GUID Partition Table (GPT).
∙Supports unlimited number of partitions.
∙Supports full capabilities of new devices - new devices may not provide backward
compatibility.
∙Supports secure startup - UEFI can check the validity of the operating system to
ensure that no malware tampers with the startup process.
Incompatible UEFI cases
∙32-bit Windows operating system - this motherboard supports only Windows 10
64-bit operating system.
∙Older graphics card - the system will detect your graphics card. When display a
warning message There is no GOP (Graphics Output protocol) support detected in
this graphics card.
⚠
Important
We recommend that you to use a GOP/ UEFI compatible graphics card.

AMD RAID Configuration
AMD RAID Configuration
The following are the RAID levels supported by RAIDXpert2.
RAID 0 (Striping) breaks the data into blocks which are written to separate hard
drives. Spreading the hard drive I/O load across independent channels
greatly improves I/O performance.
RAID 1 (Mirroring) provides data redundancy by mirroring data between the hard
drives and provides enhanced read performance.
RAID 10 (Striped RAID1 Sets) uses four hard drives to create a combination of RAID 0
and 1 by forming a RAID 0 array from two RAID 1 arrays.
Volume (JBOD) provides the ability to link-together storage from one or several
disks, regardless of the size of the space on those disks. Useful in
scavenging space on disks unused by other disks in the array. Does not
provide performance benefits or data redundancy.
RAIDABLE (also known as RAID Ready) allows the user to add more storage space or
create a redundant array after a system is installed.

60 AMD RAID Configuration
Initializing Disks
New disks and legacy disks must be initialized before they can be used to create an
AMD-RAID array. Initialization writes AMD-RAID configuration information (metadata)
to a disk.
⚠
Important
∙
If a disk is part of an AMD-RAID array, the disk cannot be selected for initialization.
To initial the disk anyway, delete the AMD-RAID array. Data on the disk is deleted
during initialization so ensure the correct disks are chosen to initialize.
∙
A legacy disk can contain valid data. When a legacy disk is initialized, all data on the
disk is lost.
To initialize disks
1. As previously mentioned, enable RAIDXpert2 Configuration Utility.
2. Go to BIOS > SETTINGS > Advanced > RAIDXpert2 Configuration Utility > Physical
Disk Management > Select Physical Disk Operations > Initialize Disk sub-menu.
3. Select desired disks by changing the Physical Disk setting to Enabled.
4. Select OK, then press Enter.
5. Review the warning message, if you want to proceed, select YES, then press Enter.
6. Initialization takes 10 to 15 seconds per disk. During initialization, a complete
rescan of all channels is done automatically.
61
AMD RAID Configuration
Creating Arrays
Arrays can be created after the disks are initialized.
⚠
Important
∙
For redundant arrays, the Create process is not started until after the operating
system and AMD-RAID OS drivers have been installed and the system has booted to
the operating system. However, the arrays are immediately available to use for either
a bootable array or a data array.
∙
Array numbers are valid only for a given boot and might be different in the
RAIDXpert2 Configuration Utility and RAIDXpert2. If a permanent label is required, use
the RAIDXpert2 Web GUI Array Naming feature.
∙
At any point in the procedure, return to a prior window by pressing ESC.
∙
If the system is booted from an AMD-RAID bootable array, the first array in the
Arrays section must be the bootable array. The system boots only from the first array
in the Arrays section.
To create an array
1. As previously mentioned, enable RAIDXpert2 Configuration Utility.
2. Go to BIOS > SETTINGS > Advanced > RAIDXpert2 Configuration Utility > Array
Management > Create Array sub-menu.
3. Select the RAID level from the Select RAID Level drop down menu.
4. Enter Select Physical Disks sub-menu, select member disks by changing the
Physical Disk setting to Enabled.
5. Select Apply Changes, then press Enter to apply and go back to previous sub-
menu.
6. Change the Select CacheTagSize, Read Cache Policy and Write Cache Policy
settings according to your needs.
7. Select Create Array, then press Enter.
62 AMD RAID Configuration
Deleting Arrays
⚠
Important
∙
Deleting an array permanently destroys all data that is on the array. This action
cannot be undone and it is very unlikely that the data can be recovered.
∙
Do not delete the first array listed in the Arrays section, if it is the AMD-RAID
bootable array. Doing this deletes the operating system and AMD-RAID files.
To delete an array
1. As previously mentioned, enable RAIDXpert2 Configuration Utility.
2. Go to BIOS > SETTINGS > Advanced > RAIDXpert2 Configuration Utility > Array
Management > Delete Array sub-menu.
3. Select the desired array and change the setting to Enabled.
4. Enter Delete Array(s) sub-menu.
5. Review the warning message, if you want to proceed, Select Confirm and change
the setting to Enabled.
6. Select YES then press Enter.
