6.6 Graphics cards with different amounts of
memory
Graphics card with different amounts of memory can by used with
CrossFireX™. However, restarting your computer is required. This will
cause CrossFireX™ 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 CrossFireX™ you will be given the option to restart
your computer to restore the original graphics memory size or
continue with the reduced memory size.
6.7 Card Reversal Recommend
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 CrossFireX™ can be enabled, performance may be
improved by reversing the graphics card in the computer.
See you motherboard's manual to determine which is the primary PCIe™
slot.
