  • Slot 2: PCIe Gen 5 x8 (open end), 75W, FH/FL
  • Slot 3: PCIe Gen 5 x16, 75W, FH/FL
  • Slot 4: PCIe Gen 5 x8 (open end), 75W, FH/FL
  • Slot 5: PCIe Gen 5 x16, 75W, FH/FL
  • Slot 6: PCIe Gen 4 x8 (open end), 75W, FH/FL
  • Slot 7: PCIe Gen 4 x16, 75W, FH/FL
  • Slot 8: PCIe Gen 4 x8 (open end), 75W, FH/FL
  • Slot 9: PCIe Gen 4 x8 (open end), 75W, FH/HL
Note

  • Slots 2, 4, 6, 8, and 9 in ThinkSystem ST650 V3 are open-end design, which means that these slots can accept adapters with a longer edge connector than the physical length of the slot connector. For example, if a x16 adapter is installed in the x8 slot 2 of the server, half of the edge connector will not be connected to the slot. The adapter will still function, but the performance will be impacted.

  • See Install a HL PCIe adapter for detailed information about the technical rules of PCIe slots.

  • For more information about the supported PCIe adapters, see Lenovo ServerProven website.
