Installing and Configuring the EVGA nForce 680i SLI Motherboard PCI Express x1 Slot There is 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. Jumper Settings The motherboard contains a 3-pin BIOS configuration jumper that enables all board configurations to be done in the BIOS Setup program. The silk screen on the motherboard shows a ∆ next to pin 1. Clear CMOS Jumper: CLR_CMOS The motherboard uses the CMOS RAM to store all the set parameters. The CMOS can be cleared by removing the CMOS jumper. Use the following procedure to clear CMOS: 1. Turn off the AC power supply and connect pins 1 and 2 together using the jumper cap. 2. Return the jumper setting to normal (pins 2 and 3. Together with the jumper cap). 4. Turn the AC power supply back on. 28

PCI Express x1 Slot
There is 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.
Jumper Settings
The motherboard contains a 3-pin BIOS configuration jumper that enables all
board configurations to be done in the BIOS Setup program.
The silk screen on the motherboard shows a
∆
next to pin 1.
Clear CMOS Jumper: CLR_CMOS
The motherboard uses the CMOS RAM to store all the set parameters. The
CMOS can be cleared by removing the CMOS jumper.
Use the following procedure to clear CMOS:
1.
Turn off the AC power supply and connect pins 1 and 2 together using the
jumper cap.
2.
Return the jumper setting to normal (pins 2 and
3.
Together with the jumper cap).
4.
Turn the AC power supply back on.
