  2. 1 x PCI Express x16 slot, running at x8 (PCIEX8)
    (The PCIEX16 and PCIEX8 slots conform to PCI Express 3.0 standard.)
    * The PCIEX8 slot shares bandwidth with the PCIEX16 slot. When the PCIEX8 slot is populated, the PCIEX16 slot will operate at up to x8 mode.
    * PCIE Gen.3 is dependent on CPU and expansion card compatibility.

  3. 1 x PCI Express x16 slot, running at x4 (PCIEX4)
    * The PCIEX4 slot shares bandwidth with all PCI Express x1 slots. All PCI Express x1 slots will become unavailable when a PCIe x4 expansion card is installed.
