PCI_E1~6: PCIe Expansion Slots

* For Ryzen™ 1st and 2nd Generation processors
** For Ryzen™ with Radeon Vega Graphics processors
Important
If you install a large and heavy graphics card, you need to use a tool such as MSI
y
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
y
the PCI_E1 slot is recommended.
When adding or removing expansion cards, always turn off the power supply and
y
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.
PCI_E4 will run x1 speed when installing devices in PCI_E2/ PCI_E3/ PCI_E5 slot.
