I had the same problem as you have.
but now it's enabled after I downloaded and reinstalled the latest driver on AMD website.
Hi i had problem with my new Mac Pro , under Bootcamp i didn't have the option to activate crossfire. After several new Installations from WIN 8.1 i look for some help.
i didn't have to install any new drivers, you just need to restart the machine twice just to get all the drivers loaded and settled - after you get logged into windows the first time
Hey guys is there anybody out there ????? Someone with a D500 with running crossfirex here ? Is it normal that i can find the second D500 card in the control panel ? what is the right driver to use ? Please i need help , i still wait months for the Mac and now i go wild![]()
