I have tried two different Crossfire bridges and i have tried switching them around in different pcie slots (i have them in my 16x pcie slots) i have tested them one by one they work just find by them self. I don't know what else to try. Specs are MSI 990fxa-gd80 mobo, AMD 6200fx 3.8 Ghz, 600 GB WD HDD, MSI and HIS 7850's and a 750w Corsair gold PSU Please help me find a fix for this.
My HIS 7850 and MSI 7850 will not talk to each other (HELP)

Ok, this is going to sound insulting, but have you connected the crossfire bridge between the two cards?

after that,
How to get Crossfire going:
1. install latest version of Drivers found Here
2. reboot
3. open up the AMD catalyst control panel
4. go to 3d application Settings
5. make sure crossfire is enabled for the games you want to play

Now, do they have the same amount of vram....if they do not have matching v-ram quantities, they simply won't work together (like say one is a 2gb model and the other is a 4gb variant)

Worst case scenario is that you don't have a crossfire capable motherboard.
otherwise, you need to make sure crossfire profiles are setup for all your different programs

They will not work together with different vram quantities. It's just common knowledge. any sli and crossfire tutorials will also say the same thing

You've got your facts wrong.
The GPU is different in SLI -- won't work.
GPU is different but class is same in crossfire, will work
RAM will scale to smaller.
Clock speed will scale to smaller.
GPU HAS TO BE SAME for SLI however.
Even the gtx460 and gtx460 v2 will not sli because one GPU is gf104 and other is gf114.

Yes, this is the differences between sli and crossfire now. nvidia is kinda sticky on what you can and cannot sli together while the amd cards are much more lenient. Now let's get back to the problem
So I made a profile for BF4 and now both cards are running at about 45%-50% ingame and runs at about 75 fps with "microstudders" that's just a problem with crossfire and sli in bf4 tho. Did the same with War Thunder and it ran just fine with both cards being utilized. Thanks for the help!
