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 appropriate AMD
driver and configuration software for your card to take full advantage of the
capabilities of your card. You should also reinstall AMD drivers each time you reinstall
or upgrade your operating system.
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."
Included with your driver installation is AMD Radeon™ Settings which is a software
application that lets you control and manage your graphics product. Using
AMD Radeon Settings, you can adjust display, video, and other graphics features,
including AMD Eyefinity, AMD CrossFire™, and AMD OverDrive™ technology.
When connecting displays to a DisplayPort connection, the type of adapter and display
that you use may determine the number of displays that can be used with your
graphics card.
•
An active adapter allows a non-DisplayPort display to be connected a
DisplayPort connection using DisplayPort signals.
•
A passive adapter also allows a non-DisplayPort display to be connected to a
DisplayPort connection but using non-DisplayPort signals.
•
Transmission of audio and video information between variants of the same
connection type (for example, Mini DisplayPort to standard DisplayPort and vice
versa) are considered to be native, active connections.
More information on the number and type of displays that can be supported by your
graphics card is provided in the following sections.
3.3 Connecting Displays
AMD Eyefinity technology is a solution that allows up to six displays to be
simultaneously run off a single graphics card. The AMD Radeon™ R9 390 Series
graphics card is capable of AMD Eyefinity technology and can support Ultra HD
resolutions via the DisplayPort and HDMI connections.
As many as six DisplayPort displays can be connected and controlled independently
per DisplayPort connection using DisplayPort 1.2 multi-stream transport (MST) hubs
or daisy-chain configurations. Hubs and displays in this setup must be capable of the
DisplayPort 1.2 standard.
The following table lists options for attaching displays to your graphics card. The types
of display configurations that can be used depend on the display connections that are
available on your graphics card.
For best graphics performance and quality, always use native (or active) connections
when possible.
Note: Adapters/dongles that are not provided with your graphics cards can also be
purchased from AMD's Web site or through your local AMD resellers.

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
multiple 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://
4.2 Installing Additional Graphics Cards for
AMD CrossFire™
Before installing an additional graphics card, make sure that your system meets the
recommended system requirements for AMD CrossFire technology. If needed,
consult your system builder or OEM to confirm that your system has an adequate
power supply.
For optimal performance, it is recommended that each AMD Radeon™ R9 390 Series
graphics card be separated by at least one empty expansion slot. For more
information, see the installation instructions for your graphics card.
4.3 Enabling and Configuring AMD CrossFire™
Once all your graphics cards are properly installed, you can begin enabling and
configuring AMD CrossFire technology support using the AMD Radeon software
application, which is a component of the AMD graphics driver that can be downloaded
from the Drivers and Support page at http://support.amd.com.
When AMD CrossFire is enabled, the graphics processor in one of the cards acts as the
primary processor; this card is known as the primary graphics card. Graphicsrendering tasks are shared between all available processors to accelerate displays that
are connected to the primary card. By default, displays that are connected to other
graphics cards are disabled but may be enabled by unlocking them.
Note that AMD CrossFire technology can be use with AMD Eyefinity technology
however displays must be connected to the primary graphics card.
Install a different graphics card. If there are no display issues, then the graphics
card in question may be defective.
•
If your motherboard has on-board graphics capabilities, you may need to disable
them. Consult your motherboard documentation for more information.
Note: Some manufacturers do not allow the on-board graphics to be disabled or to
become the secondary display.
For more troubleshooting tips, see knowledgebase article 737-22472: How toTroubleshoot No Display on Re-start Issues.
Verify that the installation instructions were followed correctly.
Make certain that the graphics card is properly connected to the power supply and
the motherboard.
For Windows® operating systems, restart your system in Safe Mode. Use Windows
Device Manager to remove any graphics driver entries under Display Adapters and
restart your system.

For more information, see the AMD CrossFire Web page at http://game.amd.com/us-
en/crossfirex_about.aspx.
5.1.2.2 Use Graphics Cards with Different Amounts of Memory
In some AMD CrossFire configurations, graphics cards with different amounts of
memory can by used; however, restarting your computer is required after enabling
AMD CrossFire. This will cause AMD CrossFire to reduce the amount of memory on
the card with the most amount of memory to match the memory size of the graphics
card with the least amount of memory.
Clicking OK to the memory mismatch error message will restart your computer.
Note: When disabling AMD CrossFire you will be given the option to restart your
computer to restore the original graphics memory size or continue with the reduced
memory size.
5.1.2.3 Card Reversal Recommended
A recommendation message to reverse the graphics card positions may appear if the
primary graphics card is not installed into the primary PCIe slot. Although
AMD CrossFire can be enabled, performance may be improved by reversing the
graphics cards in the computer.
See your motherboard's manual to determine which is the primary PCIe slot.
5.1.2.4 3D Client is Active
You will not be able to start AMD CrossFire if a 3D application, game, or video playback,
such as a DVD movie, is running.
Close all open 3D applications, games, and movie player applications, and then enable
AMD CrossFire.
