PCI Express Cards.
The PCI Express x1 card slot is not available for use if a graphics card is installed in each of the PCI Express x16 card slots in a dual-graphics card
configuration. If you are upgrading from a single graphics card to a dual-graphics card configuration, you will need to remove any card installed in the PCI
Express x1 card slot (see System Board Components to locate the PCI Express x1 card slot). To remove a PCI Express card, see Removing PCI and PCI
Express Cards.
To learn more about dual-graphics technology, see "Understanding Dual Graphics Technology" in your Owner's Manual.
1. Follow the procedures in Before You Begin.
2. Remove the computer cover (see Removing the Computer Cover).
3. If present, press the tab on the card-retention device that lays over the installed cards and rotate it upwards to gain full access to the card.
4. Press down the tab on the top of the card retainer at the appropriate card slot and pivot the card retainer back through the chassis wall.
5. Remove the filler bracket or existing graphics card (see Removing a PCI Express Graphics Card from a Dual Configuration) to create a card-slot opening.
6. Prepare the card for installation.
See the documentation that came with the card for information on configuring the card, making internal connections, or otherwise customizing it for your
computer.
7. Position the card so that it is aligned with the slot and the securing tab (if present) is aligned with the securing slot.
NOTE: If you are upgrading to a dual-graphics card configuration and have a card installed in the PCI Express x1 card slot, remove the card (see
Removing PCI and PCI Express Cards).
