3	(default)	7	Processor 1	Standard Height	Full Length	x8	x16
3	(alternate)	6	Processor 1	Standard Height	Full Length	x16	x16

NOTE: To use PCIe slots 1 through 4 on the riser, both the processors must be installed.

NOTE: PowerEdge R720xd does not support riser 3 (default).

NOTE: The expansion-card slots are not hot-swappable.

The following table provides guidelines for installing expansion cards to ensure proper cooling and mechanical fit. The expansion cards with the highest priority should be installed first using the slot priority indicated. All other expansion cards should be installed in card priority and slot priority order.
