2x radeon pro duo quadfire issue

Hi guys, I've just recently bought 2x radeon pro duos and am now having problems with getting both of them to work on quadfire or even all 4 gpus to be recognized by the computer.


The problem is that whenever I have both cards plugged in and check windows display adapter properties, it shows that only 3 cards are recognized the 4th one would have an error code 12.


That said after installing the latest crimson hotfix and going to advanced radeon settings, I've tried to turn on the crossfire there but the option for it does not appear. Even the gaming tab is not available.


However when I've removed the second pro duo, the computer recognizes the first pro duo as if it were normal and when going to the radeon settings, I am able to enable crossfire normally.


I hope someone can help me to make both radeon pro duos to work on my computer.
