I've succsessfully installed a Asus Radeon 5970 in my i7 hackintosh. Both DVI ports are working but the Mini Displayport stops working right after the apple logo disappears on boot, the screen just gets black. All the ports works with Windows.
Has somebody got the Mini Displayport working on a 5970 in OSX? I have read that the 5870 works good, all the ports are working, in OSX. Isn't the 5970 just two 5870 with lower clocks on the same board? Could you disable one of the cores and trick the graphics card that it is a 5870?
Please Help I've searched for hours and hours and i can't find anything.
