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