golfleep Posted May 30, 2015 Share Posted May 30, 2015 I have dual Sapphire Vapor-X R9 280x cards installed, which have been working well, and which I had read worked OOB. Under ATI injection with a futomaki frame buffer (chosen by Clover), the cards are reported appropriately under the system report, and utilize the AMD7000controller kext when I look in the IOreg. However, I would only have certain ports available to me depending on what frame buffer I chose. I've spent the past few days editing and testing various frame buffer edits in an attempt to get all the ports on my cards working, without much success. I've gotten various combinations working, but not all of them at the same time. After remembering someone's post about simply just turning off ATI injection and using the default radeon frame buffer, I figure I'd just try it for the sake of completeness. I was completely surprised when after just changing that "true" to "false" and rebooting, that I had all the ports on my cards available and working. Should I continue to try and customize a frame buffer personality, and am I missing out on something if I stay with the default frame buffer? I don't see any difference in Luxmark scores - although that's the only synthetic test I've run so far, and have not really seen any negative effects on performance, as far as I can tell. About the only negative (if that) is that the cards are no longer reported correctly in the system report, and show up as 7XXX vs. the 7970/8970/R9 280x that showed previously. In IOreg, instead of the AMD7000controller, it's now the ATY,AMD,RadeonFramebuffer that is being used. Thanks in advance for the help Link to comment Share on other sites More sharing options...
golfleep Posted May 30, 2015 Author Share Posted May 30, 2015 Ran Unigine Heaven and Valley benchmarks with both the default radeon frame buffer and with Clover injected frame buffer, and saw no difference in bench marks between the two frame buffers.

Slice Posted June 1, 2015 Share Posted June 1, 2015 Check DVDPlayer and output to second monitor. Link to comment Share on other sites More sharing options...
golfleep Posted June 1, 2015 Author Share Posted June 1, 2015 Thanks Slice, appreciate the input and all the hard work you've put into Clover and your other projects. The output to the second monitor as well as DVD player output seem to be the same (as far as I can tell) with or without ATI injection Link to comment Share on other sites More sharing options...
