AMD Radeon HD 7750 Crossfire

Hi Chaps

Having a problem setting up my first ever custom build.

I have installed 2 graphics card onto my Asus P8h77 Motherboard.
The graphics cards are AMD Radeon HD 7750 Crossfire.

When i plug a dvi into one card and a HDMI into another (to test to make sure i have them both working i only ever get signal from the first board or first slot. I cant figure out for the life of me how to get the second card working.

Both cards work 100% as have swapped them over in the slots.

I have updated my drivers so in device manager nothing is required.

I have made sure on the catalyst program that crossfire is enabled and have also been in the bios were i thik i have selected the right part for making it display multi monitors,

Any advice would be very appreciated.


Completely stuck atm..

Thanks
Iain

Only because it isn't mentioned...

Did you put the Crossfire bridge in there?

I have been told and can also see on the board that it doesn't need one.

Duuuuuuuuuuuuuuuuuuuuuuuuuuuuuhhhhhhhhh! Of course, you're right!

I've gotta ask though, have you tried running any games yet? I'm not 100% with AMD cards, but have you tried just running a game and seeing what the performance is like? If it's good performance, Crossfire is working. If it's as slow as a single 7750, well, it's not working then.

Have you also tried using the DVI and HDMI ports from the same card?
