Important
Always unplug the power cord from the power outlet before installing or removing
the CPU.
Please retain the CPU protective cap after installing the processor. MSI will deal
with Return Merchandise Authorization (RMA) requests if only the motherboard
comes with the protective cap on the CPU socket.
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.
Whenever the CPU is not installed, always protect the CPU socket pins by covering
the socket with the plastic cap.
If you purchased a separate CPU and heatsink/ cooler, Please refer to the
documentation in the heatsink/ cooler package for more details about installation.
CPU Socket
Please install the CPU into the CPU socket as shown below.

DIMM Slots
Please install the memory module into the DIMM slot as shown below.
Memory module installation recommendation
Important
Always insert memory modules in the DIMMA2 slot first.
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 to www.msi.com for more information on compatible memory.

PCI_E2: PCIe 3.0 x1 (From B660 chipset)
PCI_E3: PCIe 3.0 x4 (From B660 chipset)
Important
If you install a large and heavy graphics card, you need to use a tool such as MSI
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.

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
capabilities.
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. It can also eliminate 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/
Windows 11 64-bit operating system.
Older graphics card — the system will detect your graphics card. If you use older
graphics cards, it may display a warning message There is no GOP (Graphics Output
protocol) support detected in this graphics card.
Important
We recommend that you replace it with a graphics card supporting GOP/UEFI or use
CPU with integrated graphics for having normal function.
How to check the BIOS mode?
1. Power on your computer.
2. Press Delete key when the Press DEL key to enter Setup Menu, F11 to enter Boot
Menu message appears on the screen during the boot process.
3. After entering the BIOS, you can check the BIOS Mode at the top of the screen.
BIOS Mode: UEFI

BIOS Setup
The default settings offer the optimal performance for system stability in normal
conditions. You should always keep the default settings to avoid possible system
damage or failure booting unless you are familiar with BIOS.
Important
BIOS items are regularly updated for better system performance. The items may
be slightly different from the latest BIOS; therefore, the description is for reference
only. You could also refer to the HELP information panel for BIOS item description.
The BIOS screens, options and settings will vary depending on your system.
Entering BIOS Setup
Press Delete key when the Press DEL key to enter Setup Menu, F11 to enter Boot
Menu message appears on the screen during the boot process.

Veuillez garder le capot de protection du processeur après l’installation du
processeur. Selon les exigences de RMA (Return Merchandise Authorization), MSI
n’acceptera pas les cartes mère dont le capot de protection aura été retiré.
Lors de l’installation d’un processeur, n’oubliez pas d’installer un ventilateur
pour processeur. Un ventilateur de processeur est nécessaire pour protéger le
processeur contre la surchauffe et maintenir la stabilité du système.
Assurez-vous de l’étanchéité entre le ventilateur et le processeur avant de
démarrer votre système.
La surchauffe peut facilement endommager le processeur et la carte mère.
Assurez-vous toujours que le système de refroidissement fonctionne correctement
pour protéger le processeur de la surchauffe. Assurez-vous d’appliquer une couche
de pâte thermique (ou adhésif thermique) entre le processeur et le système de
refroidissement afin d’améliorer la dissipation de la chaleur.
Quand le processeur n’est pas installé, protégez toujours les broches du socket
CPU avec le couvercle dédié.
Si vous avez achetez un processeur indépendamment du ventilateur, veuillez vous
référer à la documentation dans le paquet du ventilateur pour plus d’informations
concernant l’installation.

Slots DIMM
Insérer le module de mémoire dans le slot DIMM comme indiqué ci-dessous.
Installation recommandée de module mémoire
Important
Veillez à toujours insérer un module de mémoire dans le slot DIMMA2 en premier.
Pour garantir la stabilité du système au mode de double canal, assurez-vous
d’installer les modules de mémoire du même type, du même nombre et de la même
densité.
Certaines mémoires peuvent fonctionner à une fréquence réduite par rapport à
la valeur indiquée lors de l’overclocking car la fréquence d’opération de mémoire
dépend du Serial Presence Detect (SPD). Rendez-vous sur le BIOS et choisissez la
fonction DRAM Frequency pour régler la fréquence de mémoire si vous voulez faire
fonctionner la mémoire à la fréquence indiquée ou à une fréquence plus élevée.
Il est recommandé d’utiliser un système de refroidissement qui sera capable de
refroidir toutes les barrettes mémoire et d’offrir de bonnes performances lors d’un
overclocking.
La stabilité et la compatibilité du module de mémoire lors de l’overclocking
dépendent du processeur et des périphériques installés.
Veuillez vous référer au site www.msi.com pour plus d’informations sur la mémoire
compatible.

Wichtig
Ziehen Sie das Netzkabel ab, bevor Sie die CPU ein- und ausbauen.
Bitte bewahren Sie die CPU Schutzkappe nach der Installation des Prozessors auf.
MSI wird RMA (Return Merchandise Authorization) Anfragen nur dann behandeln,
wenn die Schutzklappe auf dem CPU-Sockel des Motherboards sitzt.
Wenn Sie eine CPU einbauen, denken sie bitte daran, einen CPU-Kühler zu
installieren. Ein CPU-Kühlkörper ist notwendig, um eine Überhitzung zu vermeiden
und die Systemstabilität zu gewährleisten.
Stellen Sie sicher, dass Ihr Kühlkörper eine feste Verbindung mit der CPU
hergestellt hat, bevor Sie Ihr System starten.
Überhitzung beschädigt die CPU und das System nachhaltig. Stellen Sie stets eine
korrekte Funktionsweise des CPU Kühlers sicher, um die CPU vor Überhitzung zu
schützen. Stellen Sie sicher, dass eine gleichmäßige Schicht thermischer Paste
oder thermischen Tapes zwischen der CPU und dem Kühlkörper vorhanden ist, um
die Wärmeableitung zu erhöhen.
Schützen Sie den CPU-Sockel immer mit der Plastikabdeckung, wenn keine CPU
installiert ist.
Verwenden Sie bitte die Installationsanweisung des Kühlkörpers/Kühlers, falls Sie
eine seperate CPU oder einen Kühlkörper/ Kühler erworben haben.

DIMM Steckplätze
Setzen Sie bitte ein Speichermodul wie untern gezeigt in den DIMM-Steckplatz ein.
Speichermodul-Installationsempfehlung
Wichtig
Um einen sicheren Systemstart zu gewährleisten, bestücken Sie immer DIMMA2
zuerst.
Stellen Sie im Dual-Kanal-Modus bitte sicher, dass Sie Module des gleichen
Typs und identischer Speicherdichte in den DIMM Slots unterschiedlicher Kanäle
verwenden.
Einige Speichermodule können beim Übertakten auf einer niedrigeren Frequenz
arbeiten, als der festgelegte Wert — abhängig von dem SPD (Serial Presence Detect).
Stellen Sie im BIOS-Setup mit DRAM Frequency die Speicherfrequenz ein, wenn Sie
mit der festgelegten oder einer höheren Speicherfrequenz arbeiten möchten.
Es wird empfohlen, ein effizienteres Speicherkühlsystem bei einer Vollbestückung
des DIMMs oder beim Übertakten zu verwenden.
Die Stabilität und Kompatibilität beim Übertakten der installierten Speichermodule
sind abhängig von der installierten CPU und den installierten Geräten.
Weitere Informationen zu kompatiblen Speichermodulen finden Sie unter:
www.msi.com.

UEFI BIOS
Das MSI UEFI-BIOS ist mit der UEFI-Architektur (Unified Extensible Firmware
Interface) kompatibel. Das UEFI-BIOS hat viele neue Funktionen und besitzt Vorteile,
die das traditionelle BIOS nicht bieten kann. Es wird zukünftige PCs und Geräte, die
der UEFI-Firmware-Architektur entsprechen, vollständig unterstützen. Das MSI
UEFI-BIOS verwendet UEFI als Standard-Startmodus, um die Funktionen des neuen
Chipsatzes voll auszunutzen.
Wichtig
Der Begriff „BIOS“ bezieht sich in diesem Benutzerhandbuch auf das UEFI-BIOS,
sofern nicht anders angegeben.
Vorteile von UEFI
Schnelles Booten — UEFI kann das Betriebssystem direkt booten und den BIOS-
Selbsttestprozess speichern. Außerdem entfällt die Zeit, um während des POST in
den CSM-Modus zu wechseln.
Unterstützt Festplattenpartitionen, die größer als 2 TB sind.
Unterstützt mehr als 4 primäre Partitionen mit einer GUID-Partitionstabelle (GPT).
Unterstützt eine unbegrenzte Anzahl an Partitionen.
Unterstützt den vollen Funktionsumfang neuer Geräte – neue Geräte bieten
möglicherweise keine Abwärtskompatibilität.
Unterstützt sicheren Start – UEFI kann die Gültigkeit des Betriebssystems
überprüfen, um sicherzustellen, dass keine Malware den Startvorgang
beeinträchtigt.
Inkompatible UEFI-Fälle
32-Bit-Windows-Betriebssystem — Dieses Motherboard unterstützt nur das 64-Bit-
Windows 10/ Windows 11-Betriebssystem.
Ältere Grafikkarten — Das System erkennt Ihre Grafikkarte. Bei Erkennung einer
nicht kompatiblen Grafikkarte wird die Warnmeldung „Auf dieser Grafikkarte
wurde keine GOP-Unterstützung (Graphics Output Protocol) erkannt“ angezeigt.
Wichtig
Wir empfehlen Ihnen, eine GOP / UEFI-kompatible Grafikkarte zu nutzen oder eine
CPU mit integrierter Grafikeinheit zu verwenden, um eine normale Funktion des
Systems zu gewährleisten.
Wie überprüfe ich den BIOS-Modus?
1. Schalten Sie den Computer ein.
2. Während des BOOT-Vorgangs drücken Sie die Taste ENTF, wenn die Meldung
Press DEL key to enter Setup Menu, F11 to enter Boot Menu erscheint.
3. Nach dem Aufrufen des BIOS können Sie den BIOS-Modus oben auf dem
Bildschirm überprüfen.
BIOS Mode: UEFI
30
BIOS Setup
Die Standardeinstellungen bieten die optimale Leistung für die Systemstabilität unter
Normalbedingungen. Sie sollten immer die Standardeinstellungen behalten, um
mögliche Schäden des Systems oder Boot-Fehler zu vermeiden, außer Sie besitzen
ausreichende BIOS Kenntnisse.
Wichtig
BIOS Funktionen werden für eine bessere Systemleistung kontinuierlich
aktualisiert. Deswegen können die Beschreibungen leicht von der letzten Fassung
des BIOS abweichen und sollten demnach nur als Anhaltspunkte dienen. Für eine
Beschreibung der BIOS Funktionen rufen Sie die HELP Informationstafel aus.
Die BIOS-Bildschirme, -Optionen und -Einstellungen variieren je nach System.
Öffnen des BIOS Setups
Während des BOOT-Vorgangs drücken Sie die Taste ENTF, wenn die Meldung Press

Overview of Components
CPU Socket
Please install the CPU into the CPU socket as shown below.
Important
- Always unplug the power cord from the power outlet before installing or removing the CPU.
- Please retain the CPU protective cap after installing the processor. MSI will deal with Return Merchandise Authorization (RMA) requests if only the motherboard comes with the protective cap on the CPU socket.
- 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.
- Whenever the CPU is not installed, always protect the CPU socket pins by covering the socket with the plastic cap.
- If you purchased a separate CPU and heatsink/cooler, Please refer to the documentation in the heatsink/ cooler package for more details about installation.

Memory module installation recommendation
Important
- Always insert memory modules in the DIMMA2 slot first.
- 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 to www.msi.com for more information on compatible memory.
PCI_E1~3: PCIe Expansion Slots
