Configuring Key ForceWare Graphics Driver Features
Power Supply
Some graphics cards that are capable of supporting SLI technology may require an
external power cable.
As SLI technology based computers support up to two high-end graphics cards,
the load on the computer’s power supply can increase significantly. A minimum
of a 450W Power Supply Unit (PSU) is recommended.
Note:
An inadequate power supply can result in erratic and unpredictable system
behavior.
Note:
For the latest updates on SLI technology-certified power supplies, see
www.slizone.com/content/slizone/build.htm.
Installation and Operating Instructions
Note:
Before removing current graphics cards and installing two NVIDIA GeForce-
based graphics cards, be sure to uninstall any current drivers.
Installing the Hardware
Note:
Perform the installation in a static safe environment and utilize a properly
grounded anti-static wristband. Place any static sensitive components in anti-
static bags.
1
Turn off the computer and remove the power cord from the power supply.
2
Gently remove or open the system enclosure.
Refer to the owners manual that came with your computer.
3
Remove any graphics cards that are not SLI technology- capable and may occupy
the x16 expansion slot and replace them with your SLI technology-capable
graphics card.
4
Install the second SLI technology-capable graphics cards in the adjacent slot.
You may also need to relocate a card. The chosen slot must be x16, x8 or x4
capable.
5
Connect the two graphics cards with the SLI bridge connector.
