Hardware that seems relevant:

    Video cards - Powercolor 7870 HD Myst Edition (Tahiti LE) x 2
    Mobo - ASRock Z97 Fatal1ty
    PSU - 750w

Things I have done to try and resolve this:

    Uninstalled drivers/CCC
    Uninstalled display adapters and let windows find the cards
    Updated BIOS
    Checked BIOS for CrossFire setting and can't seem to find any option that would help
    Reseated both cards
    Swapped card slots
    Can't plug the Bridge onto another slot because there is only one on these cards
    I've tried the newest normal and beta version of the drivers...maybe I should go farther back?


I feel like I've tried everything that I can think of and from what I can google, so now I'm here. :|

Have you got the xfire bridge on from card to card?

Are both cards locked into their pcie slots?

Are the power supply connectors on both cards?

Do both cards show up in Device Manager? And working OK?

Do you need to update CCC?

Well something isn't working.

Sure you've got it set up right in CCC?

I'm not talking about drivers. I'm talking about CC being up to date.

I downloaded CCC directly from the website. I clicked on Update at the bottom and it says everything is up to date.

Hmmm OK. I'm running out of ideas.

Does the card work in another pc?
Does another card work in your pc?

Both cards work fine when plugged in by themselves. Windows is picking up the other card and reads it in the Device manager but still no CrossFire option.

A few things:

Just to be sure, have both cards got the same amount of VRAM?

Someone recently said that their bridge had to be slightly less than all of the way on to work properly, could try that

It sounds to me like a faulty bridge cable (Failing my other 2 suggestions), so if you could find another one of those then try that (If anyone you know has bought an AMD card then they should have one)

@i7Baby - The PSU is Coolmax CUL-750b and should be compatible.

@CGurrell - They're the same exact cards. The bridge is brand new and I've tried the second, since I have two. I'll try the whole, "not on all the way" bit, but that sounds sketchy.

Your psu should be per - http://www.tomshardware.com/answers/id-1804779/power-su... - preferably Tier One.

Those specific models aren't in any Tier. By default they are in Tier Five - 'immediately replace'. At least think about it.

And yeah - some bridges you do have to push hard to get them on properly.
