ZOTAC nForce 790i-Supreme SLI Motherboard
PCI Express x16 Slots
These three 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 three 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).
3. Turn the AC power supply back on.
