1 or 2 crossfire connectors?

I am about to buy a second Radeon HD 4850 so I can run a crossfire setup.

After looking at ATI's website, I can only find a flash demo, no written instructions.

With two cards, do you only need one internal crossfire connector, or both?

I figure it would be one, since if you run a tri or quad crossfire setup, you have one bridge between each card (as far as I know), but I'm wondering if using 2 connectors would increase bandwidth between the cards.


Will check back in a few hours when I go to get the second card.


Thanks ahead of time for any and all help!

You may need to use two bridge connectors,depending on the resolution of your monitor. If you are running a high resolution ,such as 1920x1200,With only one bridge attached, CCC will report a lower resolution for your monitor and not allow you to go higher. Adding the second crossfire bridge will cure that.

but with one connector only for 2x hd4850 i get better scores than this review at this adress below

my cpu is q6600 so i had to overclock it to 3.6 to come close the testers pc, even then it outperforms mine yet my crossfire does better with one connector....
