2.9 Installing Add-In Cards
Before installing add-in cards, it’s helpful to know if they are fully compatible with
your motherboard. For this reason, we’ve provided the diagrams below, showing
the slots that may appear on your motherboard.
PCI-E Gen. 2 x16 slots (PCIE_1 & PCIE_2)
NOTE: The PCIE_1 slot is designed to fit both add-on PCI-E card and riser card
(M2091). However, The PCIE_2 slot is designed for riser card only (M2091-R).
Therefore, you can not insert an add-on PCI-E card directly in the PCIE_2 slot.
Simply find the appropriate slot for your add-in card and insert the card firmly. Do
not force any add-in cards into any slots if they do not seat in place. It is better to try
another slot or return the faulty card rather than damaging both the motherboard
and the add-in card.
TIP: It’s a good practice to install add-in cards in a staggered manner rather than
making them directly adjacent to each other. Doing so allows air to circulate within
the chassis more easily, thus improving cooling for all installed devices.
NOTE: You must always unplug the power connector to the motherboard before
performing system hardware changes to avoid damaging the board or expansion
device.
