Radeon™ HD 3800 CrossFire™ Edition User Manual

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.
