PCI_E1~6: PCIe Expansion Slots
PCI_E1: PCIe 3.0 x16
PCI_E2: PCIe 2.0 x1
PCI_E3: PCIe 3.0 x16
PCI_E4: PCIe 2.0 x1
PCI_E5: PCIe 3.0 x8
PCI_E6: PCIe 3.0 x8
Important
y
For a single PCIe x16 expansion card installation with optimum performance, using
the PCI_E1 slot is recommended.
y
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.
y
With MSI PCI-E Ambient Light feature, you will be able to easily find out which PCIe
x16 slot is operating with full 3.0 x16 speed. Red PCIe LED ambient light indicate the
PCIe x16 slot is operating at full 3.0 x16 speed, and white PCIe LED ambient light
indicate the PCIe x16 slot is operating at 3.0 x8/ x4/ x1 speed. You can also refer to
the PCIe 3.0 bandwidth table for details.

* U.2_1 will be un-available when installing a PCIe device in PCI_E6.
** The M.2 PCIe slot can only support PCIe 2.0 x2 speed if the PCI_E6 slot or U.2 port be installed.
Note: PCI_E1 shares the bandwidth with PCI_E5.
