      • Slot 4: x16 (Gen4 x8 lanes)

      • Slot 5: x16 (Gen4 x8 lanes)

      Note
      • When the serial port module is installed, Slot 5 is not supported.
      • When a double-wide GPU is installed in Slot 3, Slot 4 is not supported.

    • PCIe riser 2 (optional)

      • Slot 6: x16 (Gen4 x8 lanes)

      • Slot 7: x16 (Gen5 x16 lanes)

      • Slot 8: x16 (Gen4 x8 lanes)

      Note
      • Slot 6 and Slot 8 are not supported in the following configurations:
        • Front SATA drive backplane and internal NVMe drive backplane connect to the system board
        • Front NVMe drive backplane and internal NVMe drive backplane connect to the system board
      • When a double-wide GPU is installed in Slot 7, Slot 6 is not supported.

  • OCP module slot

    • Slot 9: Gen5 x16 lanes (with NC-SI support)

Graphics processing unit (GPU) and accelerator
Supports one of the following:
