  1. M using ROM for my AMD Radeon HD 7650m from internet resources, is it ok coz I’ve tried GPU-Z, AIDA64,DarwinDumper,DPCI Manager but no luck.
    M getting Full QE/CI, only wanted to know if its ok to use someone ROM(same device) or it will cause problem to my graphics card.
    Is VBios ROM device specific !
    Also m having Gradient Issue !
    Fully Confused.

    i can see rom in Ubuntu 14.01 (Live USB)!
    ubuntu@ubuntu:~$ find /sys/devices -name “rom”
    /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/rom <- this is Bios (131kb)
    /sys/devices/pci0000:00/0000:00:1c.0/0000:02:00.0/rom <- this is VBios ROM (65kb)

    only need to copy !
    Ive used Sudo but no luck !
    But y does ubuntu is giving I/O error !

  3. SO if i use the clover bootloader ati injection then i would not need the dsdt injection ?
    i have clover boot loader and my card is amd 7970 GHZ 3Gb.my info shows 7xxx 3Gb.. but i think the gpu is not fully utilizing.. i can run 3d apps like uniengine but still feels laggy..
    any help how i can enable full QE/CI for my card. i am very new to hackintosh and also quite confused..

    Reply
    • You do not Need injection for that Generation after 10.8.3. Only some Cards from that Generation Need injection.

      You have fully functioning graphics if you see the Ram ammount.

  9. Hi,

    I have an XFX R9 270. You stated at the top of the page that Sapphire and XFX card’s BIOS are natively unsupported. What do I need to flash it with?

    Thanks

    Reply
    • You do not Flash the Card. You use the ROM Loading Features of the Boot Loader.

      Reply
      • Oh ok, so the card will stay safe then? And the ROM loading features are within Clover?

        Would that just be the ‘ATI=True’ flag?

        Thanks

        • I don’t understand the Part 5 patches for the AMD 270 – could you or anyone else help please? What is supposed to be done with this information?

        • This is a Framebuffer patch. See Framebuffer Editing for more info on how the patch was made and how to apply the patch.

          That said, you do not Need to use the FB if you do not have a issue when one is not loaded. IE when proper GPU and ROM is used.

  11. I have an AMD Radeon HD 6570 card, i just installed yosemite 10.10.1 and I use chameleon bootloader, but I can only boot with -x boot flag so I don’t have QE/CI.

    Or do I need to look at different kernels?

  12. Hello, I have HD 6370M running on ProBook 4421s. I used EDID injection to boot. I thought everything was fine but it turned out there’s still this thing. Every time I open an image file with Preview the image gets distorted. I may say it’s not even viewable. But that only happens when displaying image using Preview. Playing videos and watching videos on the internet seems fine though. Do you have any idea on this issue?

  13. Can you tell me more about it? I’m not really into this. I tried each frambuffer booting like this:
    AtiConfig=”Gibba”

    Are you suggesting to try each framebuffer with atiports bootflag? So for example:
    AtiConfig=”Gibba” AtiPorts=0
    AtiConfig=”Gibba” AtiPorts=1
    AtiConfig=”Gibba” AtiPorts=2
    Etc. Etc.?

    Which is the maximum numer of ports tha i should try?
    Should i also add the GraphicsEnabler=Yes bootflag? And/or any other bootflag?
    Thank you for your kind help.

  14. 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? I have two 7970M btw, using a modded Buri frame buffer.

  19. My exact Graphics Card is a “Sapphire Radeon HD 7950 OC FLEX With BOOST” and i bought this card because i was told this will work OOB, but it turned out that i got the white screen and black screen issue and i don´t have a integrated Graphic Card (Intel Core i5 750). since 10.9 the Card works just fine the only Problem is, it only works with the DVI-Dual Link Port together with Clover and ATI=true FB=Futomaki. Other ports, FB or Bootloader don´t work at all. I tried to edit the personalities my self, but with no luck no ports working, This is what bios Decoder says:

  24. Dear Rampage,

    Your guides have been very helpful while doing my first hackintosh attempt. Thanks for your efforts, guides and for sharing your knowledge!

    My system is composed by Asus P6T motherboard (No delux, no SE, just P6T) Bios Version 1408, I7 920 (not overclocked), GPU: XFX Radeon HD7750 1 SSD & 2 HDD SATA. I took my 320GB disk and used it to install Yosemite 10.10.3 with Chimera . After some research I got audio, network, etc. working.

    I extracted the DSDT from windows, added some kexts for audio and network and voilá!

    The only issue I have is with the GPU. I cannot get full acceleration. I followed your guide, installed kext/drivers, injected the code into DSDT (no errors). After the injection, my card is recognized as HD7750 but with 7MB memory, when it actually has 1GB. I have tried every framebuffer personality there is, I changed my device ID (0683f) code as first in AMD7000Controller.Kext’s plist and on AMDRAdeonX4000.kext, but I’m still unable to get acceleration. I can get 1920×1080 resolution, but the resolution without the acceleration is nothing.

    Is there anything you’d suggest I do in order to get the card working properly?

    Thanks!

  25. Andrew – I have dual Sapphire Vapor-X R9 280x installed and they are working great, other than a port issue. When I tried to hook up a second monitor today, I realized that none of the other display ports were functional (DisplayPort, HDMI, dual-link DVI), only the single-link DVI (which is what I had been using) is functional. I had thought these cards worked OOB, but I guess not! What would be the best approach to troubleshoot at this point? Do I need to try out the various frame buffers you have listed in your AMD guide?

    • You may need to use a FB to enable these functions.

      Reply
      • Thanks for you reply. I played around with various framebuffers and with editing the personalities that worked the best, but have not yet successfully gotten all the ports on the cards to work, other than by turning off ATI injection completely. When I turn off ATI injection, all ports work and I have not yet been able to detect any issues in terms of graphics acceleration and performance. The only thing I’ve noticed is that the proper card is no longer displayed, but rather AMD Radeon 7xxx is displayed (the memory displayed is correct, however). Are there any issues with not using a framebuffer, or something I should be looking for in particular in terms of performance issues?

  26. For the Mavericks 10.9.2 applied this method
    (Patched-DSDT & Patched AMD6000Controller.kext) = iphomea
    and its working good
    AMD 6650M 1GB

    However.
    I installed Yosemite 10.10.3, and used the same DSDT with updated(patched new) kext but despite the DSDT the kext is not active at all. Actually i applied same method to 10.9.3, 10.9.4 but same results i got.

    Normally it is supposed to work. Isn’t it.
    Detailed answer/answers much appreciated.

  27. Hello, Just a quick note to let you guys know how I solved my issue with XFX Radeon HD7750. As it turned out, I didn’t have to inject the code to DSDT.

    I made a clean Yosemite install. Restarted with -x. Copied the original Kexts for AMD7000Controller and AMDRadeonX4000 kexts installed with fresh Yosemite to the desktop. Then installed some kexts (old version 1.20. something) I found on the web and this allowed me to start my hackintosh ok but without accelleration. After normal restart I edited the original AMDRadeonX4000.kextinstalled the original and editex kexts and IT WORKED! Full acceleration, full 1920×1080 resolution and no mouse lag!

    I have my doubts about the procedure, but it worked for me and thought it might help somebody!

    • I am currently using Mavericks with (patched dsdt + patched 6000 controller kext) and the gpu performance is %95 compared to windows but its okay for me. As you mentioned X4000 for your HD7750. in my case have HD6650m and its related to X3000 kext, you can see that in my ioreg up there. So if i can understand what causing the real problem i could go for it.. I literally killed my notebook by the stress of shutting down and booting up cycles over thousand times for test purposes of course. 🙁 This is a very slow process.

  29. I have installed ASUS R9 280x and used your PEGP example to inject graphics. I added two more ports as 4 and 5 and adjusted the size declaration to rid the error.

    Based on the four Display ports and two DVI-D Ports, I used the Personality Ikura. Despite the card having 6 ports, ioReg shows only five framebuffers, 0 – 4, although from what I can tell, each port type is correctly identified. One DP is unidentified.

    Wrong Personality?

    If FB isn’t needed, what shall I put in the PEGP section?

    Reply
    • All ports should be defined. What you should do is take the layout you are using and then patch one that has six ports with the FB you are using for port 1-5 and then try to get the 6th port working. Or just leave it if it works fine.

    My hack is freezing everytime I am plugging/unplugging a monitor cable. No matter if its a HDMI or DVI. The same is happening when I try to rotate the orientation of a screen in system preferences. I have to restart to get it up and running again. My FB are patched, and I have picture on all three monitors so everything is working fine there. Do you have any idea why?

  36. Hello can you help me with FB patch for gigabyte r9 270x. I got a problem to get fully functional card. When i try to apply patched framebuffer i got a kernel panic. I use clover uefi and no custom dsdt, also patches are through clover. My configuration is ga-z77-ds3h + i5-3570k (intel hd 4000) + GV-R927XOC-2GD yosemite 10.10.4. hd 4000 is fully functional.

    Any ideas what can i try to do? i’ve already changed video card by money back service and got another1. Right now card is functional through hdmi, but i can’t get hdmi audio and it seems that there is a conflict beetween intel hd audio and this card, because i lose sound randomly for few minutes or get it back after sleep/wake and yes sleep/wake is functional. Thank you!

      • I have figured out that the problem was not in the patched personality, but in clover AddHDMI_8000000=true key. WIthout it system boots up. Other forum members have confirmed such clover issue as well. However i have problems with applehda, sound randomly disappears then appears (simple sleep/wake makes it appear too). I need to take a look at dsdt/ssdt editing, because clover fix is not an option here.

        Also take a look at hotplugid. Applelifedotru forum member xite666 found a dependency between transmitter and hotplugid:

        12 – 03
        22 – 04
        11 – 01
        10 – 05
        21 – 02

        yet it is not 100% accurate but

        11-01
        and
        10-05

        appears to be always 100% true relation ship.

        and data that goes before transmitter is connector number. in my case as you can see i have 1st dp 2nd hdmi 3 and 4 dvi. however i don’t know what is second pair of digits. In futomaki framebuffer from 10.10.1 there are 01 and 00. Usually in most connectors there are 00.
        01 01 1st dp
        02 01 2nd dp
        03 00 dvi
        04 00 dvi

        • Unsupported boot flag. Inject the card into a ssdt if you want HDMI audio. Do it the right way. 🙂

        • what do you mean “unsupported”? you mean that it simply doesn’t work for me?
          well i know it already)

        • That Boot flag is not supported means its broken.

        • btw i think it is better to make a standalone ssdt rather then keep all in one dsdt, right? then how i can clear main dsdt from card and then add it in ssdt? thanks!
          I mean that if i simply want to remove or change video card i will remove ssdt alongside with card and keep main dsdt without any changes.

        • Nothing should be in the DSDT. All edits to the DSDT can be done externally using the SSDT. That is what the DMGs are all about.

        • Hello do you know anything about progressbar artifacts (progressbar prior login screen). i have these artifacts like on hd4000 and can’t get reed of them. I tried to change dp and hdmi connector number but the only thing changed is that progress bar changes it’s possition from left bottom corner to middle of the screen (where progressbar should be).

    I delete the Fake Id 0x100267b0, and restart with the rest of the modification that you put and works fine. In About this Mac show ¨R9 290X 4096 MB¨, and the test are similar or a little less than before, with nothing added in Config File.

    Any Suggestion?

          However without the fake ID, I get the black screen upon boot. I’m going to play with this some and see if anything helps.

    • No go here.

      I’m only using the DVI-DL port since my monitor is DVI-DL only.

      Though the default 8xxx framebuffer seems to work just fine, minus the fans that don’t ramp up under load. Hopefully the fan fix will work for that at least.

  42. > The only way I found in your problem is check wich smbios are you using. In my case is Mac 14.2 .

    I’m using iMac 14,2 but I see 15,2 is required. I’ll change it and see if the patch works.

    Also, I applied the fan fix (El Capitan Beta 6) but I haven’t noticed any difference using the default framebuffer. Probably needs patched for it to work correctly.

    If I can’t get it to work under iMac 15,2 what would the next step be? What would I need to post?

      I tried your card from a friend, and works in two monitors (DVI + HDMI). No black screen. No fan issues. It’s not fast as my card, justo a little less than a Sapphire reference card. I know Asus is a better card. The only thing I do was do the Guide exactly as Andrew propose from zero. I think Andrew has a combination of files, and script that works better. So, It’s not the last versions of files as I thought, he knows which works and how fit in the major of hacks and hardwares.

      I don’t know if this is the best result for our card. I think 290x has more to give. Now I’am using my Sapphire with Baladi, the patch and nothing else – no fake ID – in two monitors. In Final Cut works better than a 980 and for me it’s enough.

      My recommendation it’s start with a total fresh install from here. Maybe Andrew find something else for this incredible and maybe most powerful card from the range.

      Reply
      • Which method are you using with the card? DSDT/SSDT Injection or Clover injection?

        Reply
      • Yeah, tried it again several times and still no go. It’s strange, it *should* work but it doesn’t. I’ve triple checked everything, it’s following the tutorial for Clover inject to the letter.

        I tried using a clean Clover install and config using the config.plist in the Haswell.dmg – only adding the parts needed to boot El Capitan and the AMD framebuffer patch and it still doesn’t work. Tried both DVI-DL ports and it didn’t make a difference, only a black screen. I’m using one of those Korean Qnix 27″ 1440p DVI-DL only monitors.

        I also tried the dual BIOS switch on the card, doesn’t help either (it’s set on uber mode right now). Also tried using iMac 14,1 and 14,2 and 15,1 and that didn’t work. Then I tried MacPro 3,1 as suggested and MacPro 6,1 and no dice there.

        I’ve had issues for over a year now trying to get framebuffer patches to work. Once in a blue moon I’d find one that’d work for awhile – I’ve searched down those once working patches and again no go.

        I’m highly considering at some point replacing the 290X with a GTX 980 and replacing the monitor if I need to (assuming there’s issues using the DVI-DL only monitor with a 980). Hopefully that’d be the end to the nightmare getting the card fully working as intended.

    It only works when DualLink, VRAM and VideoPorts to be set to the above values. The patch *kinda* works as in it’ll boot with the monitor working… but it glitches like crazy making it unusable. But, nonetheless it’s progress.

    So the issue for me is likely in the connectors patch. I’ll keep trying stuff… maybe I’ll get lucky.

  46. An update. Still no go with El Capitan final, which doesn’t surprise me. I’ve tried multiple patches and it still doesn’t want to work for me. It’s just really, really strange.

    • Why dont try with a cheap motherboard, gigabyte? Don’t waste your money in a 980 if you can go faster with 290x!

      • I’ve had multiple Gigabyte boards the last couple years and let’s just say I don’t ever want another one. The negative experiences have been very bad, especially in regards to support and RMA. That said, if I was going to get another motherboard I’d just get another ASUS Z97 Deluxe, which was the best board I’ve used in the last couple years.

        As for why I’m considering changing from a 290X to a 980 it’s simple… I don’t want to really mess with framebuffer patches and whatnot anymore. I’d rather just install the Nvidia web drivers and be done with it.

        Reply
  47. Yes, that motherboard is the best for me too. Great performance and compatibility.
    With Msi always I had bad expierences, like your case. GA-Ud3h and Ud5h are the most compatibles in my hacks.
    I think with Clover, you don’t have to write or modify framebuffers.
    Lot of user install El Capitan beta like an upgrade.
    I have 980 and 290X and with Final Cut X and Davinci Resolve 12, I can edit faster with AMD, 4K. Maybe 980 Ti could be better, but its expensive.
    Maybe – I never tried this, you can buy a 660 GTX and have both in the same machine. But if I have your problems, I never going to choose MSI motherboards.

  48. Hello, I want to ask for help related to R9 380. This card working OBB without any injection in Yosemite, but in El capitan after normal install and first boot we get black screen -no signal- on monitor. If we change boot option to IGPE and boot with HD4600 working normal and after that reconnect cable to R9 380 working well. If we use boot option IGPE but cable connect to R9 380, everything working except we cant see bios. So please RapageDev for your opinion. This problem is 3 months old and really is insane that we haven’t fix yet?

  49. Hello, thanks for your support. I have a XFX R9-280X and as you said that the roms are not supported, so what could be the work around? Is there any patched rom available for this gpu? Because I tried flashing to older versions but I had all sorts BSOD’s and lock-ups so I am back to stock!

    • Not supported under Mac OS X. You must use a Asus ROM for the same GPU loaded by the Bootloader to make the card work. DO NOT FLASH THE CARD or it will not work under Windows.

          I am using chamaleon and I tried putting it in the /extra folder but with no luck!
          One more question, how to rename that bios file? I mean if I use Asus ROM it will have a different revision and sub-system ID so (while renaming) should I use that or should I use the one of my current XFX Bios?

I have tried loading differnet XFX and ASUS vbios with clover. I have also tried different Framebuffers, however I think the problem may be the bios. I saw a post where you mention ASUS vbios for this card. How do I know which ASUS vbios to use?

    • GPU ROM issue. You can use ROM archive sites to get the Asus ROM. Also please reinstall since your install method is broken and will cause issues. Follow are install guide and never mix and match.

  54. oh no need for framebuffers?? i run capitan, i get my 6650m 2gb displayed as 6750m, with 2gb but the gradient issues are pretty nasty, also i cant run like xcom 2 smoothenough to have decent graphics, while i found a patch earlier that injects _dsm (like 9 lines of dsdt) and i can run the graphics on max, but still gradient.

    what would be my best bet to get full harware acceleration? (currently ipomoea patched i am using with vbios on, vbios patched, then duallink on, in vram i got 2048, and inject edid on, but i didnt put anything in there, just checked it, same as for vbios, no rom is in the folder, but i checked it. also i wanted to say my dsdt is not completely finished yet, as imstill trying to perfect it, i got a 0 error warning remark and optimize dsdt.aml atm, with ssdt from pikeralphascript for my i7-2630qm (sandy) and the pegp ssdt(4).aml is also in the patched clover acpi folder. (and i didnt inject the converted video rom to dsdt code in the pegp either as someone told me i may have to do (but they running mav and im cap) pls , any ideas would be much apreciated, i tend to post a clean overlook of the complete process of my acer 7750g as soon as i am finished, wich shuold be in the near future. thanks in advance

  58. Will my ATI 4670 work with OS X 10.10.10?

    • Some 4670 models work under Mac OS X however some never have. If your model is one that works then yes. Try using the injectors before looking to apply the SSDT/DSDT methods.

  59. Hello

    I have setup a low-cost Mavericks Hackintosh using C2D Processor + Intel Motherboard + 4GB DDR2 RAM + ASUS Radeon HD5450 Graphics card. All working fine.

    The only problem I face is when I open the Photo Preview in-build app, 1st time it show any image properly.

    When I closes the app, it takes a long long time, like minutes!

    When I try to open the same or any other image, it takes long long time and then it shows the images in garbage format!

    Somehow and some where I saw an error saying the crash is due to OpenCL error.

    What to do?

  61. Hello,

    I have tried to get my ASUS EAH HD5450 (0x68E1 1002) to work in vmware with Clover using FakeID. But whatever I do the ID is not beeing faked. SMBIOS fake works but the HD5450 is just not faked to 68E01002 which is the preferred. Is this supposed to work in Vmware?

  62. Hello,

    I’ve been trying to get my GPU working with dual monitors, but unfortunately my setup is not functioning at 100%. Currently, my Hackintosh will recognize the GPU proper name and VRAM, and boths displays work inside OSX, however, I experience slight stutters/freezing every few seconds. To be sure it was a GPU problem, I ran Novabench and got an EXTREMELY low GPU score (in the 100’s range). Over the past few days, I’ve been trying to modify my framebuffer to get everything working correctly, and although I’ve made progress from where I started (only 1 monitor working), this is basically the only remaining issue I have. Here’s some information:

    GPU: SAPPHIRE Radeon R9 270X 100364-4GL
    Monitor1: Asus 1080P (Connected via HDMI)
    Monitor2: HP 900P (Connected via DVI-D)
    Framebuffer: Futomaki
    Modified Code:
    0000000 00 04 00 00 04 03 00 00 00 01 01 00 12 04 02 02 DP
    0000010 00 02 00 00 04 02 00 00 00 01 02 00 10 00 03 06 DVI-I
    0000020 04 00 00 00 14 02 00 00 00 01 03 00 11 02 05 05 DVI-D
    0000030 00 08 00 00 04 02 00 00 00 01 04 00 22 05 01 03 HDMI

    Your listed patch for the 270x results in a green-screen on my HDMI monitor, and a sleeping DVI-D monitor. Through my experimenting of testing EVERY personality, I found that Dashimaki enabled the HDMI monitor, though with DVI-D signal. As such, I use a HotPlug ID of 01 instead of 02.

  63. Hi I have :
    Juniper XT [Radeon HD 5770] [1002:68b8]
    Subsystem: XFX Pine Group Inc. Device [1682:2990] Vervet personality 2DVI, 1DP, 1HDMI.
    I tried it with ozmosis bios on QUO motherboard in EC, but it gets stuck on the Apple logo after the verbose mode finishes, so I am not able to see the reason for freeze. Any help would be greatly appreciated.

  66. @Andrew,

    Can’t believe you’re still answering comments, that’s A-grade commitment.

    Just thought I’d post a link to a tool I wrote a long time ago (but which still works great). It was designed to complement redsock, which was written by a friend whom I was working with at the time. Unfortunately all source code to that has been lost.

    Anyways, https://github.com/sfinktah/lsframebuffer – it’s a fairly simple tool that just dumps the current framebuffer (obtained via the io registry) in a user-friendly format. I find it quite helpful for testing the results of mods. You might even consider using it in an automated boot-log-and-reboot process.

    Output just looks like this (not sure if we have markdown here):
    “`
    Prt Conect CtrFlg Conect Display
    3. 0x0004 0x0004 DL-DVI LCD
    4. 0x0004 0x0014 DL-DVI LCD
    0. 0x0400 0x0304 DP NONE
    1. 0x0400 0x0304 DP NONE
    2. 0x0800 0x0204 HDMI NONE
    ““

    The CtrFlg column should match the two of the last 3 octets in the redsock output, but only in-so-far as the framebuffer should match, and that’s what it’s displaying. It’s pre-adjusted for endieness, which is either helpful or very annoying, depending on how you operate.

  67. I’m attempting to follow your instructions to inject my ATI Radeon 4670 (Gigabyte) into my DSDT (Gigabyte P55-UD4P bios F10 from tony’s dsdt database). I have the path for my display as PCI0@0, but I’m not finding a device other than display@0, and the code just doesn’t seem that similar. Is there something I’m missing here?

    I’m running Snow Leopard and Chameleon currently, with intention to go to El Capitan and Clover.

  70. Hi!
    I’m thinking on buy an AMD HD 6970M 2GB GDDR5 from a dell laptop to put it on my iMac 27 i7 late 2009. The card is identical to the one that you can choose on a mid 2011 iMac.

    My question is if I can flash the rom from the original 6970M that comes with the Mac to the Dell version. Both versions have the same device id.

    The difference is that I only have to pay 55€ for the Dell card and about 300-350€ for the original mac version.
