Help with 290x Crossfire

I've tested each card individually in the same pci-e slot and they work fine. Ran gpu-z and I see it says x-fire is disabled. Went into ccc and see no option to enable xfire. Anyone help me out? Running AMD Catalyst™ 13.11 Beta Driver's.
 
I had the same issue. Get this program and start into safe mode (hold shift while clicking restart on windows 8/8.1 to get the menu), remove all drivers. Boot with one card only, install the 13.11 beta drivers. Reboot and make sure that card is good, then shut down and install the second card. It should pop a notification as soon as you boot up that CCC needs attention and you can then enable crossfire.
 
It worked for me, I had to go searching because I just got both cards and immediately popped them in as I have in the past, it detected both but crossfire was nowhere to be found. I'm assuming it has something to do with the new over-the-bus implementation.
 
Hmmm followed those steps (already have driversweeper installed) and I am running into the same issue. No warning from CCC asking me to fix settings.
 
Did it enable automatically? Dunno what to say then, what is the rest of your machine?
 
I got the z87 asrock extreme 4. I am using pci-e slots 2 and 4 like it says to in the mobo manual. i7 4770k 16 gig ram and few hdds with a ssd. Fan is spinning on the second card, not recognized in gpu-z though and the option to enable xfire isn't even there where it should be in CCC
Edit - Also using the NZXT 1200w PSU
 
ULPS problem maybe? If you have the latest afterburner beta try disabling that and rebooting.
 
ok I think I figured it out.... it's pretty dumb.... I unplugged the known working card from primary pci-e slot and plugged second card into primary pci-e. Booted and no display.... plugged pci-e power connectors from known working card into unknown card and it boots fine. Looks like its a loose pci-e power cable or defective psu port. Going to investigate, will report back later.
 
disaster averted.... no rma's needed (as of yet lol) Turned out I was hasty when installing the new PSU with the cards and the pci-e modular cable came loose on the power supply... once I secured that x-fire was recognized immediately and afterburner now see's 2 gpu's

thanks for the help Ligtasm
