Supported PCIe form factors

All slots support full-height expansion cards. Use the following information to find supported lengths for each
slot.
Primary riser connector
PCIe slot and card length
Slot 1 - Full-length/Full-height
(FL/FH)
Slot 2 - Full-length/Full-height
(FL/FH)
Slot 3 - Half-length/Full-height
(HL/FH)
*When a 3 x16 riser kit is installed, all slots support PCIe5 x16 Full Length and Full Height.
Definition
Each PCIe version corresponds to a specific data
transfer rate between the processor and peripheral
devices. Generally, a version update corresponds to an
increase in transfer rate.
• PCIe 1.x
• PCIe 2.x
• PCIe 3.x
• PCIe 4.x
• PCIe 5.x
The PCIe technology is under constant development. For
the latest information, see the PCI-SIG website.
PCIe devices communicate through a logical connection
called an interconnect or link. At the physical level, a link
is composed of one or more lanes. The number of lanes
is written with an x prefix with x16 being the largest size
in common use.
• x1
• x2
• x4
• x8
• x16
These numbers correspond to the maximum link
bandwidth supported by the slot.
