Hi, I just bought a Sapphire Radeon HD 7950 (http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1157&pid=1878&psn=&lid=1&leg=0), the same model that is sold as compatible for mac. 
I use clover with monitor 27 2650x1440. 
 
I have several problems; 
-DP works only 1900x1200 
-DVI works  full res if plug/unplug cable when computer is turned on
-System Informations reveals HD 7xxx instead of HD 7950
 
I have tried different framebuffer but the result, best should be Aji and Hamachi. 
I read that 10.9.3 should fix the problem, I installed kext from 10.9.3 but nothing has changed.

 

Has anyone solved the problem? Someone use a 7950 without problems?

 

Thank you.
