The jumpers below are used to select the bandwidth of the PCI
Express lanes.
Important:
When the jumpers are set to 2-3 On, the system board only sup-
port one graphics card. Install the graphics card onto the PCIE 1 slot.
Do not install any card on PCIE 3. This is a chipset limitation there-
fore if there is a card installed on PCIE 3, the system might fail to
boot.
We strongly recommend that you install the PCI Express slots with
the corresponding PCI Express cards shown in the table below.
