HP Z440 Workstation Series Service Manual

NOTE: Slots two, four, and five are PCIe GEN3 slots. Slot two is the primary graphics slot; slot five is the
secondary graphics slot.
Slots three and four use open-ended PCIe connectors, so a PCIe x16 card can be inserted. This allows the
workstation to support more PCIe x16 expansion cards. A x16 card typically trains and runs at the maximum
lane width available by the expansion slot. The card runs at the reduced lane width, with a corresponding
performance decrease. Graphics cards greater than 75 watts require the use of an auxiliary power cable
adapter.
