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.

∙

Intel® RST only supports PCIe M.2 SSD with UEFI ROM.

∙

If your M.2 SSD equips its own heatsink, please remove the M.2 plates or rubber

cubes in the M.2 slots before installing M.2 SSD. Do not re-install the heatsinks

supplied with your motherboard.
