might be worth a shot the 13.10 beta

or better use whql 13.4 first
Ulps is disabled. I'm currently using 13.4. Will try 13.10

Try 13.5 beta 2 if you can get it, that's given me the best 7950 crossfire results so far

wait I could see you have Asus DCUII. Thats the one with triple slot right? How was the spacing? But Im guessing you put the new one to first slot (or top slot) and your Asus DCU2 will be in 2nd slot.

How was the airflow of your case?

I had the same problem, I overclocked my cpu to 5ghz and I still got the same fps in cf. I tried all 13.x drivers including the beta drivers which didn't help.

CF Disabled - 189.2 FPS


CF Enabled - 142.5 FPS

Ok so I installed 13.10, and I tried it out and still not sure. I noticed something weird. Afterburner shows my clocks at 400 and 625 while in-game, ***. I also got a warning during installation, its the attachment.
Report.xml 8k .xml file

13.10 seems to be bad because I got this: http://gyazo.com/4f36afd36f0e8299fe454e096fbadb18

well, your mixing two completely different cards in the same setup, while they should in theory still work there's nothing stopping BIOS bugs appearing...

- make sure your mobo has the latest BIOS, there could also be a fault in the board itself,
- make sure your delivering adequate power, this could also refer to above,
- get info about the status of the board, make sure your cards are getting at least 8 full lanes each,
- make sure your gpus are not breaching 75-80C
- make sure your not overclocking unless you get another of the same card,
- make sure your reading the framerate correctly, the frame pacing in the later drivers can trigger various bugs, commonly the programs reading fake "dropped frames",
- ULPS must remain off until a fix comes,

report shows no errors and both cards were detected and installed perfectly fine, so I'm not sure what you mean there?

Mobo bios is up to date. Now how would I test if the cards are getting 8 full lanes and of there's a mobo issue? And by overclock, you mean the gpu or CPU?
