ATI HD4870 Crossfire setup Help needed

post #1 of 3
Thread Starter 
I now have both of my 4870's.

For setup:

Do I need to use both crossfire bridges?

If I need to use one, left or right connectors?

With respect to drivers, can I enable crossfire without reinstalling drivers?

thanks

1 bridge but if you want you can use both i always did because it just looks better. i assume you had one and are asking if you can just pop the other in and have it work without having to install the drivers again?? if so then the answer should be yes

Actually I had to reinstall the drivers once putting in the second 4850 of mine. Also you can use just 1 bridge if you want as 2 are not required.
