applehacker Posted January 14, 2015 Share Posted January 14, 2015 I have succeeded in making a single 7970M work in OS X, would it be possible to make two cards work in OSX86? Currently, even with frame buffer mod and DSDT edits, I am getting a black screen on LVDS. Would it be possible to get both cards working, or a way to disable one of the crossfire cards?

Rampage Dev Posted January 14, 2015 Share Posted January 14, 2015 You do not need a FB for 7xxx series cards. So remove the FB to start with. Link to comment Share on other sites More sharing options...
applehacker Posted January 14, 2015 Author Share Posted January 14, 2015 FB is required, it is custom patched to support internal laptop LVDS Link to comment Share on other sites More sharing options...
Rikoshet Posted February 23, 2015 Share Posted February 23, 2015 I'm interested too! Have read on Rampage Dev blog the possibility to enable, very interesting! And BTW, both card work and have internal LVDS working! Link to comment Share on other sites More sharing options...
applehacker Posted March 19, 2015 Author Share Posted March 19, 2015 I couldn't get _OFF to work because that scope is inaccessible from crossfire mode. I did make some progress though. If I plug in my HDMI cord to my TV, it activates the laptop internal LVDS screen. If no HDMI, it remains black screen. What can I do to fix this?

Pavo Posted March 19, 2015 Share Posted March 19, 2015 Just FYI there is no Crossfire mode in OS X Link to comment Share on other sites More sharing options...
applehacker Posted May 13, 2015 Author Share Posted May 13, 2015 I know, but I would like to get OS X to load on internal LVDS with both cards plugged in instead of having to take one out, which requires disassembly of the whole laptop. Link to comment Share on other sites More sharing options...
