Hello! I just registered even though I read this web since years. First of all sorry for any mistakes with my english.
The problem I'm having is that I have 2 GPU, 2x Sapphire R9 270X Dual-X 2GB GDDR5 aiming for a crossfire, but I can't get it work.
My PSU it's Corsair CX750 750W Builder Series 80 Plus Bronze and my motherboard it's Asrock Z87 Pro4.
The thing is that with the latest drivers, I just can't do crossfire, there is no option at all where it should be, some images:

That's the last drivers, 14.9
With the previous drivers (14.4 I think) I had exactly the same, EXCEPT for one driver, the one who came in the CD with the graphic, 13.10, with that drivers installed I can activate crossfire, but it feels so clunky and bad that I have worse performance, I feel laggy in a way, like the games gets stucked sometimes.
After that drivers, 13.12 doesn't fix the problem either.
So, it's proven that I can do crossfire, but not on new drivers, maybe it has something to be with the "x16 @ x16 3.0" and the "x16 @ x2 1.1" as far as I read somewhere.
I don't really know.
Using drivers 14.9:

Specification for the motherboard:
1 x PCIe 3.0 x16, 1 x PCIe 2.0 x16, 2 x PCIe 2.0 x1
I also have 1 soundcard and 1 network card attached.

Now here you have the screenshots when I'm using the drivers 13.10 with crossfire:

Any tips, please? I think I may just give up and send back the card to the store.
If I'm missing any information you may need, please let me know, but I'm seriously crazy right now.
Thanks for reading and for the help.
