The PCI Express x16 slot�is reserved for a graphics or video card. The bandwidth of the x16 slot is up to 8GB/sec. 
When installing a PCI Express x16 card, be sure the retention clip snaps and locks the card into place. If the card is not 
seated properly, it could cause a short across the pins. Secure the card’s metal bracket to the chassis back panel with the 
screw used to hold the blank cover.
