FL/FH = full-length, full-height HL/FH = half-length, full-height

For PCIe slot power capabilities, riser board installation instructions, and riser cage installation instructions, see the user guide.

*PCIe slot 3 is connected to the southbridge, and runs at Gen2 signaling rate.

Notes:

●"Primary" denotes the riser cage is installed in the primary riser connector.

●"Secondary" denotes the riser cage is installed in the secondary riser connector.

●Slots can generally run at 8 GT/s signaling rate in either PCIe2 or PCIe3 mode, depending on the capability of the installed processor.

●Installing the riser cages listed in the table above in either the primary or secondary riser connectors determines the form factor of the PCI cards supported by those riser cages.

●FL/FH denotes full-length, full-height. HL/FH denotes half-length, full-height. LP denotes low profile.
