Use Graphics Cards with Different Amounts of Memory

ati.amd.com/crossfire
Use Graphics Cards with Different Amounts of Memory
In some CrossFire configurations, graphics card with different amounts of
memory can by used. However, restarting your computer is required after
enabling CrossFire. This will cause 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 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.

Card Reversal Recommended

A recommendation message to reverse the graphics card positions may appear
if the master graphics card is not installed into the primary PCIe slot. Although
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.

3D client is Active

You will not be able to start 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 CrossFire.

CrossFire is Currently Unavailable

hardware or there is a problem with the software.

Close all running 3D applications.
