PCI Express 2.0 x1 slots
This motherboard has two PCI Express 2.0 x1 slots that support PCI Express x1
network cards, SCSI cards, and other cards that comply with the PCI Express
specications.
PCI Express 3.0/2.0 x16 slot
This motherboard supports PCI Express 3.0/2.0 x16 graphic cards complying with
the PCI Express specications.
When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that
the cards do not need IRQ assignments. Otherwise, conicts will arise between the two PCI
groups, making the system unstable and the card inoperable.
