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.

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

			DIMMA1
	DIMMA2	DIMMA2	DIMMA2
			DIMMB1
∙∙		DIMMB2	DIMMB2

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_E1~3: PCIe Expansion Slots

PCI_E1: PCIe 3.0/ 4.0 x16 (CPU)

PCI_E2: PCIe 3.0 x1 (PCH)

PCI_E3: PCIe 3.0 x1 (PCH)

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.

∙∙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.

SATA1~4: SATA 6Gb/s Connectors

These connectors are SATA 6Gb/s interface ports. Each connector can connect to one SATA device.

Important

∙∙Please do not fold the SATA cable at a 90-degree angle.Data loss may result during transmission otherwise.

∙∙SATA cables have identical plugs on either sides of the cable. However, it is recommended that the flat connector be connected to the motherboard for space saving purposes.
