Pci Slots; Pci Express X1 Slot; Pci Express X16 Slots - EVGA 680i - nForce LT SLI Motherboard User Manual

Hardware Installation

PCI Slots

The two PCI slots support many expansion cards such as a LAN card, USB
card, SCSI card and other cards that comply with PCI specifications. When
installing a card into the PCI slot, be sure that it is fully seated. Secure the card's
metal bracket to the chassis back panel with the screw used to hold the blank
cover.

PCI Express x1 Slot

There are two PCI Express x1 slots that are designed to accommodate less
bandwidth-intensive cards, such as a modem or LAN card. The x1 slot provides
250 MB/sec bandwidth.

PCI Express x16 Slots

These two PCI Express x16 slots are reserved for graphics or video cards. The
bandwidth of the x16 slot is up to 4GB/sec (8GB/sec concurrent). The design
of this motherboard supports dual PCI-Express graphics cards using NVIDIA's
SLI technology with multiple displays.
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.
To configure for SLI, follow the instructions that come with the SLI kit (the kit
is purchased separately from the motherboard).
