PCI Express x16 Slot
Install a PCI Express x16 graphics card that complies to the PCI Express specifications into the
PCI Express x16 slot. To install a graphics card into the x16 slot, align the graphics card to the
socket and perpendicularly to the board, be cautious in aligning the locations of notch and key,
and then press the card down firmly until it is completely seated. The retaining clip of the slot
will close up automatically to hold the graphics card in place.
PCI Express x8 Slots
Install PCI Express cards such as network cards, drives, or other cards that comply to the PCI
Express specifications into the PCI Express slots.
M.2 Socket
The M.2 socket is the Next Generation Form Factor (NGFF) which is designed to support mul-
tiple modules and make the M.2 more suitable in application for solid-state storage.
Note:
The PCIe x16 slot will automatically switch to x8 bandwidth when the paired PCIe
x8 slot is in use.
