Rear I/O Panel

LAN Port LED Status Table

Audio 7.1-channel Configuration

To configure 7.1-channel audio, you have to connect front audio I/O module to JAUD1 connector and follow the below steps.

Click on the Realtek Audio Console > Advanced Settings to open the dialog below
Select Mute the rear output device, when a front headphone plugged in.

Overview of Components

Distance from the center of the CPU to the nearest DIMM slot

CPU Socket

Please install the CPU into the CPU socket as shown below.

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.

DIMM Slots

Please install the memory module into the DIMM slot as shown below.

Important

Due to chipset resource usage, the available capacity of memory will be a little less than the amount of installed.
Based on processor specification, the Memory DIMM voltage below 1.35V is suggested to protect the processor.
Due to AM4 CPU/memory controller official specification limitation, the frequency of memory modules may operate lower than the marked value under the default state. Please refer www.msi.com for more information on compatible memory

CPU_FAN1, SYS_FAN1: Fan Connectors
Fan connectors can be classified as PWM (Pulse Width Modulation) Mode or DC Mode. PWM Mode fan connectors provide constant 12V output and adjust fan speed with speed control signal. DC Mode fan connectors control fan speed by changing voltage. When you plug a 3-pin (Non-PWM) fan to a fan connector in PWM mode, the fan speed will always maintain at 100%, which might create a lot of noise. You can follow the instruction below to adjust the fan connector to PWM or DC Mode.

Default PWM Mode fan connector

Default DC Mode fan connector

Switching fan mode and adjusting fan speed

You can switch between PWM mode and DC mode and adjust fan speed in BIOS > **HARDWARE MONITOR.**

Select PWM mode or DC mode

There are gradient points of the fan speed that allow you to adjust fan speed in relation to CPU temperature.

Important

Make sure fans are working properly after switching the PWM/ DC mode.
