Pci_E1~4, Pci1~2: Pcie & Pci Expansion Slots - MSI B350 TOMAHAWK User Manual

PCI_E1~4, PCI1~2: PCIe & PCI Expansion Slots
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_E2 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.
Only when both PCIe x1 slots are empty, this motherboard could support AMD
y
CrossFire™ technology.
