Installing Linked PCI Express Graphics Cards
The Desktop Board supports technology that allows you to install linked PCI Express
graphics cards such as NVIDIA* SLI* (Scalable Link Interface) cards. Make sure you
use two identical SLI-ready graphics cards that are NVIDIA certified and the latest
graphics driver. You can use the connector included with the Desktop Board to
connect the two graphics cards together. Visit the NVIDIA zone website
(http://nzone.com
) for more information.

1. Observe the precautions in "Before You Begin" on page 29.
2. In
stall the first card in the PCI Express x16 connector as described in “Installing a
PCI
Express x16 Graphics Card” on page 43.
3. Place the se
cond card in the PCI Express x8 connector (Figure 25, A) and press
dow
n on the card until it is completely seated in the connector and the card
retention notch on the card snaps into place around the retention mechanism pin
on the connector.
4. Secure the card’s metal bracket to the chassis back panel with a screw
(Figure 25, B).
5. Con
nect the two cards together with the SLI bridge (Figure 25, C) as shown.
