Intel® Server Board M50CYP2SB Family Technical Product Specification
7.2
PCIe* Riser Card Support
The server board provides three riser card slots identified as: Riser Slot #1, Riser Slot #2, and Riser Slot #3.
The PCIe* bus lanes for Riser Slot #1 are supported by CPU 0. The PCIe* bus lanes for Riser Slot #2 and Riser
Slot #3 are supported by CPU 1.
Note: The riser card slots are specifically designed to support riser cards only. Attempting to install a PCIe*
add-in card directly into a riser card slot on the server board may damage the server board, the add-in card,
or both.
Note: A dual processor configuration is required when using Riser Slot #2 and Riser Slot #3.
7.3
PCIe* Interposer Riser Slot (Intel® Server Board M50CYP2SB1U Only)
The PCIe* Interposer Riser Slot and PCIe* interposer riser card provide additional add-in card support for the
server system. The PCIe* interposer riser card shown in the following figure is an accessory option supported
by the PCIe* Interposer Riser Slot.
This card has one PCIe* add-in card slot (x8 electrical, x8 mechanical) labeled "Slot1_PCIe_x8" that supports
one low profile, half length, single-width add-in card.
The PCIe* interposer riser card also has one x8 PCIe* NVMe* SlimSAS* connector labeled
"Slot1_PCIe_AIC_Interposer".
