PCI Express improves system attributes. PCI Express enables a low-power, scalable, high-bandwidth
communication path with a small number of connections (wires) compared to traditional parallel
interfaces (e.g., PCI).
The PCI Express I/O slots can support other PCI Express cards with lesser bus bandwidth than what is
physically defined for the slot. Use the following table to determine compatibility.
For example, a PCI Express x8 card does not work in a PCI Express x1 slot, but a PCI Express x1 card
works in a PCI Express x8 slot.
NOTE:
Slot 2 and Slot 4: The HP xw6400 Workstation contains two PCI Express x8 slots that support
x4 bandwidth. If a PCI Express x8 card is plugged into a PCI Express x8 slot, the card runs at x4
bandwidth.
Slot 3: The HP xw6400 Workstation contains one PCI Express x16 slot that supports x4 bandwidth. If
a PCI Express x8 or x16 card is plugged into the PCI Express x8 slot, the card runs at x4 bandwidth.
The maximum power for a PCI Express x16 graphics card is 75W.
