Chapter 2
Hardware and Software Installation
This chapter details how to install your graphics card in your system as well as where
to download associated software and drivers.
2.1 Installation Overview
Once you have determined that your system meets the minimum requirements,
perform the following tasks to install your new graphics card. Detailed installation
instructions are provided in the following sections.
1. If you are replacing an existing graphics card, uninstall the old graphics driver
and software.
Note: If you are using a motherboard containing an on-board graphics solution
and do not intend to use it as part of a multiple monitor configuration, disable
it.
2. Turn off and disconnect your computer system.
3. If needed, remove any old graphics card(s).
4. Install the new graphic card.
5. Reassemble and connect your computer system and display(s).
6. Start the computer system and install the new AMD Catalyst™ drivers and
configuration software.
7. Restart the computer system.
2.2 Installing the Graphics Card
1. Turn off the computer, monitor(s), and other peripheral devices.
2. Unplug the computer's power cord, and then disconnect all cables from the back
of the computer.
Caution:
Wait approximately 20 seconds after unplugging the power cord before
disconnecting a peripheral cable or removing a component from the
motherboard to avoid possible damage to the motherboard.
3. Remove the cover to the computer's case.
Note: If necessary, consult the computer manual for help in removing the
cover.

Caution:
Static electricity can seriously damage computer components. Discharge
your body's static electricity by touching the power supply or the metal
surface of the computer chassis before you touch any components inside the
computer's case to avoid damaging them.
4. Unscrew or unfasten and remove any existing graphics card from the computer,
if necessary.
5. Locate the appropriate bus slot and, if necessary, remove the corresponding
metal backplate cover(s). Make sure all internal cables are clear of the slot.
Note: If you cannot find a bus slot to match the card, you need a graphics card
with the correct bus to match the motherboard.
6. Align the graphics card with the slot and press it in firmly until the card is fully
seated.
7. If your card requires supplementary power and must be connected directly to
the power supply, locate the appropriate power connector cable(s) from the
power supply and connect it (or them) to the graphics card's supplementary
power connector(s).
Note: If applicable, before installing a card that requires a supplementary
power connection, make sure your existing power supply has such a
connection available.
Tip: The location of power connections may vary between models. They can
be located on either the side or back of the card.
Figure 2–1 Possible Power Connection Locations on the Graphics Card
1 Power supply
2 Graphics card
8. Fasten the graphics card securely to the back panel.
9. Make sure no internal cables are interfering with components inside the
computer (for example, a cooling fan), and then replace the computer cover.
4 Hardware and Software Installation

10. Reconnect any cables you have disconnected during installation, and then plug
in the computer's power cord.
11. Turn on the monitor, and then the computer.
If you have properly installed the graphics card, the computer should start normally.
Proceed to install the software and drivers for your AMD Radeon R7 240/R7 250
graphics card.
2.3 AMD Drivers and Software
Drivers are small but important programs that enable an operating system to
communicate with a piece of hardware, such as a graphics card.
When you install a new graphics card, you must also install the driver and
configuration software the card requires to function properly.
You also need to install (or reinstall) your AMD Radeon drivers when you have
reinstalled or upgraded your operating system or when you download updated
drivers.
The latest drivers are available from AMD's Web site at http://support.amd.com.
Note: When reinstalling drivers, always uninstall any previous drivers that are on
your system, even if they are for the same graphics card. Always start "fresh."

3.2 Display Adapters (Optional Accessories)
The following table lists the options for connecting displays that are not directly
supported by the connection types available on the graphics card.
Adapter Description
DVI-to-VGA adapter
DVI-to-HDMI
If your graphics card includes a DisplayPort or Mini DisplayPort connection, you can
use the following types of DisplayPort-compliant adapters/dongles with your graphics
card:
•Adapter—Uses DisplayPort signals to transmit audio and video information
between variants of the same connection type (for example, Mini DisplayPort to
standard DisplayPort).
•Active dongle—Allows connection from a DisplayPort connection to a non-
DisplayPort display using DisplayPort signals.
•Passive dongle—Allows connection from a DisplayPort connection to a non-
DisplayPort display using non-DisplayPort signals.
Adapters/donglges that are not provided with your graphics cards can also be used
as long as they are compatible with your graphics card and displays. They can be
purchased from AMD's Web site or through your local AMD resellers.
A list of compatible adpaters/dongles can be found at: http://support.amd.com/us/
eyefinity/Pages/eyefinity-dongles.aspx.
3.3 Configuration Options
The AMD Radeon R7 240/R7 250 graphics card provides hardware support for up to
six displays. More than one display can be connected to a DisplayPort connection using
a daisy chain configuration or a hub (via the DisplayPort v1.2 standard).

3.4 Using Adapters
The following procedure describes how to connect a display to your graphics card
using an adapter.
1. Turn off your computer and display.
2. Plug the adapter into the connection from your AMD Radeon graphics card and
tighten the thumbscrews (if there are any).
3. Connect your display's cable to the adapter and tighten the thumbscrews (if
there are any).
4. Turn on your display first, then your computer.

AMD CrossFire™ Technology
Note: AMD CrossFire™ Technology features are available only for systems installed
with more than one compatible AMD Radeon™ graphics cards.
4.1 AMD CrossFire™ Overview
AMD CrossFire technology is designed to enhance the graphics quality and
performance of 3D games and applications by combining the processing power of two
or more AMD Radeon graphics cards, essentially creating a multi-GPU performance
gaming platform. A typical AMD CrossFire setup involves two graphics cards.
For more information, visit the AMD CrossFire technology Web page at http://
sites.amd.com/us/game/technology/Pages/crossfirex.aspx.
4.2 Installing AMD CrossFire™ Graphics Cards
These instructions assume that a PCIe® graphics card has already been successfully
installed in the secondary slot (slot one), and that the primary slot (slot zero) is empty.
Note: Consult your system builder or OEM to ensure that your system has an
adequate power supply.
For an up-to-date listing of AMD CrossFire certified motherboards and power
supplies, see support.amd.com/us/certified/Pages/certified-components.aspx.
1. Make sure the computer, monitor, and other peripheral devices are off.
2. Unplug the computer power cord and disconnect the monitor cable from the
back panel of the computer.
Caution:
To avoid possible damage to the motherboard, wait approximately 20 seconds
after unplugging the power cord before disconnecting a peripheral or
removing a component from the motherboard.
3. Remove the computer cover.
If necessary, consult the computer manual for help removing the cover.
Caution:
Remember to discharge your body’s static electricity by touching the power
supply case or the metal surface of the computer chassis.

4. Remove any unneeded graphics cards from the computer.
Warning:
Some graphics cards can get hot while operating. Wait approximately five
minutes after turning off the computer before touching the card.
5. Locate the PCIe slots on the motherboard. If necessary, also remove the
corresponding back panel cover.
6. Align the new graphics card in the secondary PCIe slot next to the existing
graphics card and press firmly until the card is fully seated.
Tip: For optimal performance in a dual-GPU AMD CrossFire configuration,
make sure that each AMD Radeon R7 240/R7 250 graphics card is separated by
at least one empty expansion slot.
7. If needed, connect the power supply to the cards.
Tip: The location of power connections may vary between models. They can
be located on either the side or back of the card.

8. If your AMD CrossFire configuration requires an AMD CrossFire internal bridge
interconnect between cards, remove the protection tags from the ends of the
AMD CrossFire interconnect before using it to connect the cards.
Caution:
Always handle the AMD CrossFire bridge interconnect by the connector only.
Do not push or pull on the flexible cable.
