lYou have performed the steps in Turning Off Your Computer and Safety Instructions.
lYou have read the safety information that ships with your computer.
lA component can be replaced or—if purchased separately—installed by performing the removal procedure in reverse order.
Technical Specifications
For information on technical specifications of your computer, see the Quick
Reference Guide that shipped with your computer or see the Dell Support
website at support.dell.com.

down your operating system, press and hold the power button for about 4 seconds to turn them off.
Safety Instructions
Use the following safety guidelines to help protect your computer from potential damage and to help to ensure your own personal safety.





1. Ensure that the work surface is flat and clean to prevent the computer cover from being scratched.

2. Turn off your computer (see Turning Off Your Computer).
CAUTION: To avoid losing data, save and close all open files and exit all open programs before you turn off your computer.
WARNING: Before working inside your computer, read the safety information that shipped with your computer. For additional safety best
practices information, see the Regulatory Compliance Homepage at www.dell.com/regulatory_compliance.
CAUTION: Only a certified service technician should perform repairs on your computer. Damage due to servicing that is not authorized by Dell is
not covered by your warranty.
CAUTION: When you disconnect a cable, pull on its connector or on its pull-tab, not on the cable itself. Some cables have connectors with locking
tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep
them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented
and aligned.
CAUTION: To avoid damaging the computer, perform the following steps before you begin working inside the computer.



3. Disconnect all telephone or network cables from the computer.

4. Disconnect your computer and all attached devices from their electrical outlets.


CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the cable from the network device.
CAUTION: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back
of the computer. While you work, periodically touch an unpainted metal surface to dissipate static electricity, which could harm internal
components.

Repeat if removing two bridges from a triple card configuration.
WARNING: Before working inside your computer, read the safety information that shipped with your computer. For additional safety best
practices information, see the Regulatory Compliance Homepage at www.dell.com/regulatory_compliance.
NOTE: If a graphics card is installed in each of the PCIe x16 card slots in the multi-graphics configuration, the PCIe x1 and one PCI card slot are not
accessible for use.

5. Remove the captive screws on top of the PCI card fan shroud and remove the shroud.

6. Remove the card retention screw(s) on the top of the card retainer at the appropriate card slot and pivot the card retainer back through the chassis
wall.

7. Press the securing tab (if present) on the system board connector as you grasp the card by its top corners, and then ease the card straight out of the
connector
.

8. Install a filler bracket in the empty card-slot opening. If you are replacing the card, see Installing Graphics Cards for Multi Graphics Card.


9. Replace the PCI card fan shroud, replace the computer cover (see Replacing the Computer Cover), reconnect the computer and devices to electrical
outlets, and then turn them on.
Installing Graphics Cards for Multi Graphics Card
This section pertains to using dual and triple PCIe graphics cards to take advantage of NVIDIA's SLI (Scalable Link Interface). For installation of other types of
PCI or PCIe cards, see Replacing a PCI/PCI Express Card.

NOTE: Installing filler brackets over empty card-slot openings is necessary to maintain FCC certification of the computer. The brackets also keep
dust and dirt out of your computer.
NOTE: The graphics card bridge (not present in all multi-graphics configurations) is not necessary in a single graphics card configuration.
CAUTION: Do not route card cables over or behind the cards. Cables routed over the cards can prevent the computer cover from closing properly
or cause damage to the equipment.
NOTE: To upgrade to or downgrade from a dual-or triple-graphics card configuration, you may need additional parts that can be ordered from Dell.

Some expansion card slots will not be available for use if a dual-slot graphics card is installed in any of the PCIe x16 card slots. If you are upgrading from a
single-slot graphics card to a dual-slot graphics card, you will need to remove any card installed in these expansion slots. To remove a PCIe card, see
Replacing the PCI and PCI Express Cards.


1. Follow the procedures in Before You Begin.

2. Remove the computer cover (see Replacing the Computer Cover).

3. Remove the captive screws on top of the PCI card fan shroud and remove the shroud.

4. Remove the filler bracket or existing graphics card to create a card-slot opening.

5. Install two SLI-ready graphics cards into the two outer PCIe x16 slots on the system board.

6. Prepare the cards for installation.
See the documentation that came with the cards for information on configuring them, making internal connections, or otherwise customizing them for
your computer.

7. Position each card so that it is aligned with the slot and that the securing tab (if present) is aligned with the slot.

CAUTION: For information about upgrading your system to use NVIDIA SLI (Scalable Link Interface) multi-graphics technology, see the Dell
support website at support.dell.com.
NOTE: If you are upgrading to a multi-graphics card configuration and have a card installed in the PCIe x1 card slot, remove the card (see
Replacing the PCI and PCI Express Cards).
