PCI Express x1 Slot
There is one PCI Express x1 slot that is designed to accommodate less bandwidth-intensive
cards, such as a modem, LAN card, or soundcard card. The x1 slot provides up to 250
MB/sec bandwidth.
PCI Express x16 Slots
These three PCI Express x16 slots are reserved for graphics or video cards. The design of this
motherboard supports three PCI-Express graphics cards using NVIDIA’s SLI technology.
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.
