⚠

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 msi.com for more information on compatible memory.

PCI_E1~4: PCIe Expansion Slots

⚠

Important

∙

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.

∙

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 5.0 x16 (From CPU)

PCI_E3

: PCIe 3.0 x4 (From Z690 chipset) 

PCI_E4

: PCIe 3.0 x1 (From Z690 chipset)

PCI_E2

: PCIe 3.0 x1 (From Z690 chipset)
