Get Triple Monitors Working on 10.9 With XFX HD 7750

Recommended Posts

Hey Guys!


I've managed to get Niresh's OSX 10.9 running on my ASUS M5A97 LE R2.0, AMD FX 8350, XFX HD 7750 System...


Works pretty well apart from the network adapter locks up every now and then when multiple downloads are running, and onboard sound was broken (no problem for me as I'm using an external USB M-Audio).


It even works well with 'Dual' 1080 Monitors and I seem to have full Graphics Acceleration.
(One monitor connected via an active Display-Port to DVI, and the other on DVI Output 1).


My Stable Config is:




The only real issue is that I have to disconnect my third monitor (plugged in to DVI Output 2) before power-on in order for the system to not lock up around 10 seconds after log on. I have tried several methods but have NEVER (well, nearly never) managed to get the third monitor to display anything other than black at all.


The configs I have tried are:


  1. GraphicsEnabler=Yes
  2. PCIRootUID=0
  3. NCPI=0x2000
  4. GraphicsEnabler=Yes

But none of these have proved fruitful, they have all ended in the same way.... with only a black screen on the third monitor (the other two showed the desktop fine and had the translucent menu bar) and then the system would lock up around 10 seconds later. Apart from number 4.... after a lot of flickering and 'FBRotate' doing it's thing the system didn't lock up but the third monitor was powered on, but black. A quick check of the more info on about this mac showed that all three monitors were recognised and active, but no picture.... I did notice that when moving the mouse between 2 screens the cursor would disappear while it apparently was travelling across the black screen, and then it would finally appear on the other working monitor! Strange! :P


I have also tried the FBRotate on user login fix, but this didn't work.


I have tried the sleep fix, which showed some promise, by which I mean the system would wake from sleep and all 3 monitors would come on and show a desktop (not mirrored! yay!) but immediately either the mouse and keyboard wouldn't work or the system had locked up (I couldn't tell which).... plus, it seemed that my CPU cooler hadn't powered back up (I use a Corsair Hydro H80i) so I immediately hard-powered off to avoid burning out the CPU!


I have even tried 'hot-plugging' the third monitor into the free DVI port, sometimes I get nothing, sometimes I get the equivalent of analogue tv static).


As a last resort I also tried the kexts for the HD 7850 from: osx86.net/file/3687-amd-hd7850-maverick-kexts-1092/ - but OSX didn't even seem to recognise my card with those installed (I did check that the device ID 0x683f existed inside them first), no avail :'(


So does anybody have any ideas in getting triple monitors working on this card, or has had any luck with anything similar?


Sorry if this is information overload!


Thanks in advance for any and all replies ;)

    • I get this message no matter what I do, I've tried changing my SMBIOS to a newer model to no avail. Anyone no how to get the second install boot to work?
    • This is my first time doing Hackintosh. I've several other machines running Mac using UniBeast and Multi beast. I wanted to try Hackintosh Vanilla. So far, no luck. I followed the Guide and MacPwn Mojave Guide. 
    • Hello! I wanted to install MacOS High Sierra, but the SSD does not appear in Disk Manager. I have a Samsung Pro 840 250GB. Is there a Driver for Intel Gigabit 82579LM Network LAN for MacOS High Sierra?
    • This is my very first post and have looked around the forums to my question but I wasn't able to find the exact specifics that I need. This is my very first windows/mac dual boot project. I chose to attempt high sierra and I hope I am posting in the correct area. High Sierra seemed to be the newest that is possibly more stable than Mojave so I chose that. I'm reaching out to the more advanced builders and experienced people. I'm currently running Win 10 as of now and bought a separate SSD to install a macOS on. Before I invest time and energy into this. I'm wanting to get the best recommendations on what OS I should choose , if my hardware will be up for the task and my best plan of attack. I'll be honest I'm not ready to bang my head on the keyboard for hours. I've been there and done that.  My hardware was some of the best at its time in 2011 and I'm not 100% confident it will work with a more up to date macOS I'm also concerned about drivers for my GPU.  All input is welcomed   Here are my current specs:   CPU
          Intel Core i7 2600 @ 3.40GHz    28 °C
          Sandy Bridge 32nm Technology
          8.00GB Dual-Channel DDR3 @ 668MHz (9-9-9-24)
          ASUSTeK Computer INC. CG8350 (LGA1155)    26 °C
          NS-24E730A12 (1842x1036@60Hz)
          1023MB NVIDIA GeForce GTX 560 Ti (NVIDIA)    31 °C
          3726GB Western Digital WDC WD40EFRX-68N32N0 ATA Device (SATA )    25 °C
          111GB PNY CS900 120GB SSD ATA Device (SATA (SSD))    33 °C

          3726GB Western Digital WDC WD40EFRX-68N32N0 ATA Device (SATA )    27 °C

    • Hi! Everything seems to install ok, but after reboot, it just says Disk Booth Failure Insert system disk and press enter.. Don't have a clue about what can I do!   Francisco
