10.4 PCIe Add-in card support
The PCIe sub-system of the server board has support for PCIe add-in cards that follow the PCIe Gen1, Gen2
and Gen3 specifications. However, the performance of some PCIe Gen3 cards may be forced to operate at
Gen2 speeds due to electrical signaling characteristic limitations that exist between the server board and some
PCIe Gen 3 add-in cards.
Intel has implemented the following PCIe Gen 3 support model for this generation of its server boards and
server systems.
10.4.1 PCIe Gen3 support – Systems configured with an Intel
®
Xeon
®
processor E5-2600
product family
For a server system configured with one or more Intel
®
Xeon
®
processor E5-2600 product family, the system
BIOS will use an embedded PCIe Gen 3 compatibility list which identifies all PCIe Gen 3 add-in cards tested by
Intel to operate reliably at Gen 3 speeds on the given server system. During POST, the system BIOS will
compare installed PCIe Gen 3 add-in cards with those included in the embedded compatibility list. If BIOS
matches an installed card to one listed on the compatibility list, the BIOS will configure the device to operate at
PCIe Gen 3 speeds. If the BIOS cannot match an installed PCIe add-in card with any device included in the
list, the BIOS will force the device to operate at PCIe Gen2 speeds.
Note: The latest available BIOS should be installed on the system to ensure the most up to date embedded
PCIe Gen 3 compatibility list is being used.
Visit the following Intel web site for a list of Intel tested PCIe Gen 3 compatible cards included in the BIOS
embedded compatibility list – http://intel.com/support/motherboards/server/sb/CS-034157.htm
10.4.2 PCIe Gen3 support – Systems configured with an Intel® Xeon® processor E5-2600
V2 product family
For a server system configured with one or more Intel
®
Xeon
®
processor E5-2600 V2 product family, the
system BIOS will configure all installed PCIe Gen 3 compatible add-in cards to operate at PCIe Gen 3 speeds
by default. For a list of Intel tested PCIe Gen 3 add-in cards, review the Tested Hardware and OS list (THOL)
using Intel’s Server Configurator Tool at the following web site:

The following tables identify the PCIe port routing for each add-in card slot on all supported riser cards as
installed in either Riser Slot # 1 or Riser Slot #2. Note the specific processor, PCIe port ID, and number of
PCIe bus lanes supporting each add-in card slot.
Depending on the riser card installed, specific PCIe ports routed from the processor IIO module provide the
PCIe interface to each riser card slot.
