1 PCI PCI PCI
2 PCIe2x16(4) x16 x4
3 PCIe2x1 x1 x1
4PCIe3x16 x16 x16
5PCIe2x4(1) x4 x1
NOTE: The PCIe designators indicate the mechanical connector size and number of electrical PCIe lanes
routed to an expansion slot. For example, x16(4) means that the expansion slot is mechanically a x16 length
connector, with 4 PCIe2 lanes supported.
Slot four is the primary graphics slot; slot two is the secondary graphics slot.
Slot 5 uses open-ended PCIe connectors, so a PCIe x16 card can be inserted.
