Available riser cards for Riser Slots #1 and #2 are common between the two slots.
1U – One PCIe* add-in card slot – PCIe* x16, x16 mechanical

Each riser card assembly has support for a single full height, ½ length PCIe* add-in card. However, riser card
#2 may be limited to ½ length, ½ height add-in cards if either of the two mini-SAS HD connectors on the
server board are used.
Note: Add-in cards that exceed the PCI specification for ½ length PCI add-in cards (167.65mm or 6.6in) may
interfere with other installed devices on the server board.
2U – Three PCIe* add-in card slots
