pduke Posted February 21, 2017 Share Posted February 21, 2017 Hi all! so after 6 months of dead ending(!!) and finally with the priceless help of MaLd0n, I am writing from my new Sierra installation! CPU: XEON E5 2670 v1 Board : x79 Lenovo Erazer X700 GPU : XFX R9 180X RAM: 16GB G.Skill RipjawsX 1600MHz PSU : Corsair rm750 Surprisingly enough using injectATI and Load vBios (with some Asus, sapphire etc roms - nearly everything works fine except the XFX one...) in the clover settings, I managed to get my XFX R9 280X working great well it wasn't so great after I run cinebench in which I got a maximum of 42 fps (while in windows it reaches 98 fps). so loaded some 3d games and noticed that the card is using about 40WATTS in full 3d gaming and off course the in game FPS are ridiculously low (and that I have the most energy friendly Tahiti chip in the history of French Polynesia ) so is this a kext thing - Sierra recognises the card and its memory of 3GB , or this is the best I can get by injecting a different rom with load vbios? could this be anything related to power ? (turbo boost doesn't work either but this is a much more common problem as I read in other threads) I am totally confused.... Link to comment Share on other sites More sharing options...
pduke Posted March 3, 2017 Author Share Posted March 3, 2017 and finally it is working!! it was under my nose all the time. it seems that the stock rom is incompatible but not all XFX roms. so after testing here is what is worked (for my card at least) - DD Black Edition https://www.techpowerup.com/vgabios/148939/xfx-r9280x-3072-131026(1080Mhz memory clock) - DD https://www.techpowerup.com/vgabios/147218/xfx-r9280x-3072-130926(1000Mhz memory clock) - Nearly every Asus, Sapphire and Gigabyte 280X rom from the same site (150Mhz memory clock!!!! > Ultra energy efficient (!!) but poor performance. Not bad though for simple everyday tasks) Clover : 1. FB Name = Hamachi 2. tick Load VBios 3. tick Inject ATI In EFI : download one of the above Roms, rename it to 1002_6798.rom and place it at CLOVER/ROM/1002_6798.rom. (I keep the ASUS Rom as backup) attaching screenshots. so only turbo boost for me to solve! and my Mac is kicking asses!!! Link to comment Share on other sites More sharing options...
p.sudo Posted August 11, 2018 Share Posted August 11, 2018 I did pretty much that so far, but my XFX 280X DD is running at 150MHz and I've tested tons of different ROMs from either XFX and Asus. The ones that worked are all still running at 150MHz. I can't figure it out how to make it run properly. I've read that someone used MacPro5,1 definition and deleted the AppleTYuMCE.kext and his LuxMark got up, but I disabled this same kext within Clover and nothing changed. I shouldn't make a difference if I disable it in Clover or delete, right? I'm clueless and stuck at this 150MHz thing. Link to comment Share on other sites More sharing options...
p.sudo Posted August 11, 2018 Share Posted August 11, 2018 I don't know if this means anything but there is no GPU info being output on HWMonitor at all. Link to comment Share on other sites More sharing options...
nirvanausual Posted May 25, 2020 Share Posted May 25, 2020 curiously this spec recommends a 650w strong PSU but I don't think that's the problem. That system should be able to Run at a good FPS. Have you checked for the latest drivers? Link to comment Share on other sites More sharing options...
