⚠
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.
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.
The PCIe x1 slot and onboard Wi-Fi module share the same bandwidth, you can not
∙
use both of them simultaneously, and the default setting is the Wi-Fi module for the
system. Please disable the Onboard Wi-Fi Module Control in BIOS if you want to use
the PCIe x1 slot.
