Pci_E1~4: Pcie Expansion Slots - MSI MEG Z490 GODLIKE Quick Start Manual

PCI_E1~4: PCIe Expansion Slots

⚠
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.

Note 1: You need to set the 3.0 x4 mode in BIOS for installed M.2 device to operate
PCIe 3.0 x4 speed.
Note 2: PCI_E4 will only operate at 3.0x1 speed and M2_3 will only operate at 3.0x2
speed when both PCI_E4 is occupied with PCIE x4 card and M2_3 in use.
