2 Radeon Cards?

Hi Guys,

Today I went out and bought 2 new graphics cards. Since I'm looking for screen real estate, and not gaming, I got 2 Sapphire Radeon R7 260X 2GB cards to replace my Nvidia 610's.

I installed the cards, and I cannot for the life of me get all 6 monitors to work at once. I installed the drivers, and checked pretty much everything I can think of. My displayport adapters are active, not passive, however I had the same issue with the passive adapters too. If I disconnect one of the cards, I get a picture on the other 3 monitors. And then if I reconnect it, I get a picture on those. Catalyst control center doesn't even recognize that there are 6 monitors attached, however windows device manager shows both cards.

Additionally, I tried plugging in one monitor into each card, and that did not make a difference - it still worked on one or the other. I tried both display ports, both DVIs, and both HDMIs, as well as a combination of the 3.

Other specs

- 8GB DDR3 RAM
- AMD 9590 8-Core 4.7GHz Processor
- Gigabyte 990FXA-UD3 board
- 600 Watt PSU
- Windows 7 Ultimate (64)

 

Hi,

Got it resolved. It was due to CrossFireX being enabled. CrossFireX disables the second card's outputs, and just uses it for graphics processing.

 

Thanks for posting the solution!
