1) Ensure that the second graphics card you plan to install:
- Has the NVIDIA® SLI™-Ready badge on the box
- Has the same graphics processing unit (GPU) as the SLI-Ready card already installed in your PC. (Note: The graphics card manufacturer may be different, as may the GPU clock and memory speeds, but the GPUs MUST match. For example, if you have a GeForce 7600 GS-based graphics card, your second card, regardless of manufacturer, must have a GeForce 7600 GS GPU in order to take advantage of SLI technology.
IMPORTANT NOTE: Static electricity is dangerous for PC components. Avoid working in areas with high static electricity (avoid carpeted areas). Whenever you are about to touch the insides of a PC, be sure to ground yourself by touching either the power supply or the outside frame of the PC before touching any interior components.
2) Remove the side panel on your PC to expose its components. Along the back of your PC case, there are between 4 and 8 metal inserts, each about 4.5 x 0.75 inches in measurement. These "tabs"are usually secured by small Philips head screws. Locate the second PCI Express slot on your SLI-Ready motherboard. This slot is immediately below where the first graphics card is installed. Using a Philips screwdriver, remove the corresponding "tab" for the second PCI Express slot
3) With the SLI-Ready graphics card in your right hand, and the back of the card facing to your left (and the back of the PC), gently insert the card into the open PCI Express slot. When installing the card, ensure that the gold "fingers" on the card line up with the slot on your motherboard.
While lining up your gold "fingers" with the PCI Express slot, also make sure that you line up the back plate (the part of the graphics card that your monitor plugs into) in between the edge of the motherboard and the back of the case – this back plate will go where the tabs used to be (see step 2).
Most SLI-Ready motherboards come with a small clip on the PCI Express slot, located toward the front of the PC. This is designed to engage with the "hook" on the SLI-Ready graphics card, and you will hear it "snap" into place once the SLI-Ready graphics card is seated firmly into the PCI Express slot. Remember to move slowly and carefully when installing the card into the slot.
4) Once your SLI-Ready graphics card is securely seated in the PCI Express slot (and you've heard the audible "click" securing it in place, gently tug upwards to ensure that it's locked down in place on the motherboard. Next, where the back plate meets the back of the PC, screw the one (or two-depending on the size of your graphics card) screws through the back plate, and into the back of the PC, to further secure the card in place. This will ensure that there is no "up and down" travel with the graphics card when the PC is positioned upright. Replace any remaining "tabless" openings with their original tabs and screws, reversing the order in step 3.
5) Locate the second PCI Express power cord from the SLI-Ready power supply and plug it in to the second graphics card.
6) Attach the SLI connector to the golden "fingers" on each graphics card. Every SLI-Ready motherboard comes with an SLI connector designed to work with that motherboard. Note that when you power up the PC, you'll want to ensure that the video connector (to your monitor) is plugged into the same card it was before – the "top" card, or original card that was installed prior to adding this second card.
7) Plug in your PC's power supply and turn on the PC.
8) When you first boot up, you will be greeted with a "pop up" bubble in the lower right hand corner, telling you that you have an SLI-enabled PC – click on the message. Once you click on the message you will be taken to a desktop properties menu, which will allow you to enable SLI technology by checking a single box or radio button; check the box or button and select the "Apply" button. Note: Currently, SLI technology does supports one display when enabled. If you have multiple displays and wish to use more than 1 display, you will need to disable SLI technology in the same desktop properties menu. You can enable SLI technology at any time, but note that you will only be able to power 1 display when enabled.
YOU HAVE NOW ENABLED SLI TECHNOLOGY!
