post #1 of 3
Thread Starter 
Will a 4850 1gb work with a 4850 512mb in crossfire mode?

IIRC, it should work perfectly fine. The only problem is it would only take advantage of 512MB RAM.

Yes, they will work but you will only have 512mb of effective memory. If you use two cards that have different amounts of memory, then the amount of usable memory defaults to the card with the lowest memory. It will act like both cards only have 512mb of Vram.
