Radeon HD 7850 Crossfire Questions!

[Jollebolle]

Well hello there!

So, I`ve recently installed a second sapphire 7850 graphics card and I have some questions. First of all I had major problems just starting up the pc, screen froze, disconnected xfire bridge and then everything back to normal.. Anyway after 2,5 hours of troubleshooting it seems to run smoothly now (Don`t ask me what I did cuz honestly, I have no idea)

Okay, so... I just installed trixx and looked at some of the info and I noticed the drivers, bus width, interface and shaders are not the same.. So I wanted to post the info here and hopefully have some of you more experienced broskis to have a look and hopefully tell me I shouldn`t worry too much

About the drivers, shouldn`t both cards run off the same driver? If thats not the case, is it prefered to have another driver for the second card? and how would I even get 2 of the same drivers

Yeah thats fine but running crossfire is never recommended its far to buggy

If everything is working now I'm not sure how we can help.

You can ignore all that driver information you posted. I don't know why it's different, but that's certainly a mistake. The shaders couldn't possibly be of different number. Both cards are running from the same driver from what you posted.

Both cards HAVE to run from the same driver. You should usually just have the latest driver installed (avoid Beta versions).

*I see no issues. Enjoy.
