nlbailey Posted December 16, 2011 Share Posted December 16, 2011 Haven't been able to find anything definite on this card. Anyone have it working in lion / link to post or instructions? Looking to purchase a new card and found it for a good price. Thanks! Link to comment Share on other sites More sharing options...

Mine got one DVI port working only and its RAM size is wrong (should be 1024MB instead of 1536MB) Link to comment Share on other sites More sharing options...
Edkroket Posted December 21, 2011 Share Posted December 21, 2011 I have all ports working but audio I don't know I don't use it. I play movies from my Hack on my tv trough HDMI and sound comes from my Hack with that. Never used audio trough hdmi but I think it should be possible I've seen topics here about that. Use the latest Chamera bootloader and add Graphics enabler to Yes, don't use GraphicsMode! And do not use ATY_init or something like that. Here is a good start for your card. http://www.tonymacx86.com/viewtopic.php?f=15&t=35148&hilit=AppleGraphicsPowerManagement.kext+edit Ed Link to comment Share on other sites More sharing options...
