Overview of Components

⚠

Important

∙

Always insert memory modules in the DIMMA2 slot rst.

∙

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 nd 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 e󽙎cient 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

∙

When adding or removing expansion cards, always turn o󽙋 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.

∙

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.

PCI_E1: PCIe 4.0 x16 (From CPU)

PCI_E3: PCIe 3.0 x1 (From B660 chipset)

PCI_E4: PCIe 3.0 x1 (From B660 chipset)

PCI_E2: PCIe 3.0 x1 (From B660 chipset)
