AMD Radeon R7 260X User Manual

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.
6.1.2.3 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.
6.1.2.4 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.
6.1.2.5 AMD CrossFire™ is Currently Unavailable
This error has occurred because AMD CrossFire did not correctly detect your
graphics hardware or there is a problem with the software.
•
Check that the graphics cards are installed correctly.
•
Check that the interconnect cable, if applicable, is installed correctly.
•
Close all running 3D applications.
•
Check that the AMD CrossFire mode is set to Software in the Control Center
application. (The AMD Radeon™ R7 260X can only use AMD CrossFire technology
in software mode.)
•
Reinstall the Control Center software application and drivers. For more details,
see knowledgebase articles GPU-57: How to Uninstall Pre-existing Graphics Card
Drivers and GPU-33/GPU-1/GPU-2: How to Install AMD Catalyst Software on
Windows® 7/Windows Vista®/Windows® XP.
6.1.2.6 Screen Rotation is Unavailable or Does Not Work
Screen rotation is not an available feature on AMD CrossFire systems.
6.1.2.7 Video Displays Flicker During System Startup
This is normal during AMD CrossFire startup.
6.1.2.8 AMD CrossFire™ Disabled after Swapping/Moving Cards
If you change the AMD CrossFire configuration by moving the graphics cards to
different slots on the motherboard, disable AMD CrossFire and restore factory default
settings in the Control Center software application first. Once the cards have been
swapped, enable AMD CrossFire. This ensures the new configuration is detected by
the computer.
