Expansion cards and expansion card riser (optional)
NOTE: A missing or an unsupported expansion card riser logs an SEL event. It does not prevent your system from powering
on and no BIOS POST message or F1/F2 pause is displayed.
Expansion card installation guidelines
Your system supports PCI Express Generation 2 and Generation 3 expansion cards.
Use the following table as a guide for installing expansion cards to ensure proper cooling and mechanical fit. The expansion cards
with the highest priority must be installed first by using the slot priority indicated.

NOTE: The optional dual riser module is installed on PCIe slot 1 and 2 on the system board.
NOTE: When your system is installed with the optional dual riser module in PCIe slot 1 and 2 on the system board, you
cannot install an expansion card in PCIe slot 3 of the system board.
NOTE: When x16 card installed in PCIe Slot 1 on dual riser module the PCIe Slot 2 on the expansion card does not function.
The expansion card riser can be used either with four x8 PCIe cards or with one x16 PCIe card on PCIe Slot 1 and two x8
PCIe cards on slots 3 and 4 of the dual riser module.
