Thank you for this! Is there a chance of solving the 290x multi-screeen issues by following this?

 

Yes. Per example I got a problem with second DVI connector on Radeon 6850 HD which I was been able to fix by using this method.

Well, I tried but unfortunately it seems this method is not enough for the 290x. I followed your tutorial and made a few patches for the Baladi personality (the only one in AMD8000Controller) but none of them seem to make any difference - boots fine with one screen, as soon as you plug another one in -> black screen.

 

It was worth a shot I guess :) Thanks for the effort, hopefully someone will figure this out one day.

 

I'm attaching my "notepad" from this, maybe it will be of use to someone: http://pastebin.com/zMJbg8xP

There are several guides out there already for connector patching, but last time i had to patch a framebuffer I had to get the information from like 3 different places. Now it's all in one place. Thank you for such a comprehensive guide.

My 290X (ASUS 290X DirectCU II OC) results are the same as yours (came up with the exact same patch using this guide), however every time I try either DVI-D port it never works - just black screens on boot. DVI-D is the only output my monitor displays, so I'm stuck with it. What Clover settings do you use?

Just barebone defaults with imac14,2 preset and trimenabler patch, no graphic injections.

Thanks. Unfortunately, no matter what I do I can't get stable DVI-D output. Either the patch(es) cause black screens upon boot indicating the patch is a failure, or it boots normally with the glitchy DVI-D output causing me to put OS X to sleep then immediately wake it to workaround the DVI glitches.

i dont understan in step 3,, 
where you get this code ? --- = First I’ll put the list of all types of connectors:

 

Connector Type LVDS 0 × 00000002 = 02 00 00 00 Note: Laptop Monitor

Connector Type DVIDL 0 × 00000004 = 04 00 00 00 Note: Dual Link DVI

Connector Type VGA 0 × 00000010 = 10 00 00 00

Connector Type SV 0 × 00000080 = 08 00 00 00

Connector Type DP = 0 × 00000400 00 04 00 00

Connector Type HDMI 0 × 00000800 = 00 08 00 00

Connector Type DVISL 0 × 00000200 = 00 02 00 00 Note: Single Link DVI

Well, it seems like I am the first one to be successful and  praise your outstanding post:  (I did this for cosmetic fix in System Profiler )

 

I got an Asus R9 280x (R9280X-DC2T-3GD5), with vBIOS version: 6798HB.15.39.0.0.AS04 (113-AD47800-100) , I extracted the BIOS with GPU-Z v0.8.0. 

 

Like you calculated, i got similar results: 

Typ 1: DP:  	21 03 01 04
Typ 2: HDMI:	11 02 02 03
Typ 3: DVI-I:	12 04 03 02
Typ 4: DVI-I:	00 10 04 02
Typ 5: DVI-D:	10 00 05 06

My Graphics Card was using Futomaki before (atleast 1 Screen worked, i have a DSDT injection for the Framebuffer), so I decided to use it as well.  (But this shouldn't bother us in any way, since we are going to modify it completely anyways, right?).  Since i have two DVI- Dual-Link Screens connected, I wanted to have two DVI Lines, so my final Code was:

00040000  04030000  00010401  21030104  <- DP    (init. as last) 
04000000  14020000  00010101  12040302  <- DVI-I (init. as first)
04000000  14020000  00010200  10000506  <- DVI-D (init. as second)
00080000  04020000  00010300  11020203  <- HDMI  (init. as third) 

I used the Clover Method with Patch AMD7000Controller, and it is working like a charm.

Thanks for the great info..

My graphics card is Mobility Radeon 4870 on an Alienware m17xR2 .. i got it working with 10.10 Exotic pack QE/CI works .. my only issue that i can't get the HDMI connector to work thats the contents of the info.plisit file in the AMDFramebuffer.kext in S/L/E :

Thanks for the tutorial! I always wanted to know how you made your driver packs. I'm happy I can do it myself now if needed.

However, I have an Asus 270 (non-X) and have some questions about some things that were not entirely clear from your guide:

 

- I understand the device id for the 270X is already in AMD7000Controller but the one for the 270 is not. I guess I can add it manually, but I was wondering if there was an update-proof way? What if I use clover's fakeid feature to set it to the 270X id (the hardware is very similar, no?). Will this work or will things go wrong.

 

- Do I still need to enable the "Inject ATI" feature in Clover? What does it do anyway... 

 

- Do I still need something like ATYinjector.kext from your original pack? What was its purpose, is it the same as the Clover Inject ATI? I always assumed if your id was in the kext the driver would be loaded and if the framebuffer is correct it would work. But apparently you needed this for the 270X so I'm curious what it does.

 

I was hoping you could help me figure out these details so I can get my 270 working with your method.

Thanks again!

Those lines represents definitions of all connectors inside the code. This is just example or explanation so that you know what is what!

1. Clover should do the trick with fake serial number, but you'll need to patch kexts too (AMD7000Controller.kext and AMDRadeonX4000.kext). Check the Step - 4 in this tutorial.

 

2. Yes. This option injects proper FB + in your case fake serial number

 

3. No. You don't need ATYInjector.kext from the pack. Inject ATI option via Clover do the same thing, so you don't need it.

Thanks for this topic!

 

I have a XFX DD 270X on 10.9.5. I was using the default radeon FB, but was unable to get 2560x1440 DVI DL display+ 1920x1080 DVI/HDMI display working with it.

 

Loading FB via DSDT and can confirm it is loading.

 

Why can I not get my Dual-Link DVI working at full resolution? See below. Thanks!

Is it possible to get my mini-DPs working? Any ideas?

 

 

 

I have edited Futomaki to the following:

 

00 04 00 00 04 03 00 00 00 01 03 01 12 04 01 01 :: Not working mini-DP (tested with single-link active mini-DP to DVI cable)

00 08 00 00 04 02 00 00 00 01 02 00 11 02 03 03 :: Fully working HDMI

04 00 00 00 14 02 00 00 00 01 01 01 10 00 04 06 :: Dual Link DVI-I (only working as single-link; if I plug in my dual-link DVI then screen stays black, but IOreg shows attached display here)

00 02 00 00 14 00 00 00 00 01 05 00 21 03 06 05 :: Fully Working Single Link DVI-D

 

 

Not using:

00 04 00 00 04 03 00 00 00 01 04 01 22 05 02 02 :: Another DP (did not work when tried it earlier)

04 00 00 00 14 02 00 00 00 01 01 01 00 10 05 06 :: Dual Link DVI-I Internal KLDSCP_DAC1

 

 

EDIT:

Switched Futomaki to:

04 00 00 00 14 02 00 00 00 01 01 01 00 10 05 06 :: Dual Link DVI-I Internal KLDSCP_DAC1

00 08 00 00 04 02 00 00 00 01 02 00 11 02 03 03 :: HDMI no longer hotplugs, but will work as second monitor with the Dual-Link DVI plugged in!

04 00 00 00 14 02 00 00 00 01 01 01 10 00 04 06 :: Dual Link DVI-I (Now works as Dual-Link DVI-I if replugged after loading OS X) 

00 02 00 00 14 00 00 00 00 01 05 00 21 03 06 05 :: Single Link DVI-D no longer hotplugs, does not work at all with Dual-Link DVI plugged in and prevents Dual-Link DVI from showing anything.

Well, that was bittersweet.

 

I went back to a vanilla AMD7000Controller.kext out of curiosity and the DVI Dual Link + HDMI (or SL DVI) works OOB. Turns out my version of 223x chameleon was too old to make the default radeonFB work properly (I guess) =/

 

Installed 2510 and the defaultFB just works.

I can't get the Radeon_bios_decode or redsock_bios_decode to work in terminal. I don't know what I'm doing wrong. But, I did look at the info.plist in the AMD7000Controller.kext package. it shows the following frame buffers and what appears to be 4 ports.

 

Z77N-WIFI, Sapphire r9 270x Vapor-X, 10.10.1, latest Chameleon w/DSDT

 

Hamachi

Ikura

IkuraS

Kani

KaniS

Maguro

Namako

 

It shows the same thing on my real iMac 12.1 Radeon 5750,  Hackintosh 10.9.5 backup, Hackintosh 10.10.1 current installation, also iMac 12,1 definition. I'm trying to patch my DSDT to fix the speed.

With 10.9.5 I get 2850 FPS in NovaBench and 1590 Lux. With 10.10.1 I get 701 FPS in NovaBench.

I can't get the bios decoding files to work either, terminal gives me "Permission denied".

 

OSX will only boot if I have InjectATI enabled in Clover, and even then it finds the card properly, but reports it as 7MB in "About this Mac". If InjectATI is false, OSX starts the boot sequence, but then just reboots and repeats.

 

Any help for an XFX R9 270x Double D would be appreciated. System details in signature

Vlada- Thank you for the post.

 

But Im a little slow on this stuff. If you have a bit of time and feel like checking my calculation I thank you more. Or anyone else that knows and is quicker.

      Hello there!
       
      TL:DR; I built a Hackintosh system using the OpenCore Vanilla Desktop Guide (running Catalina 10.15.4) and I use an AMD Ryzen 1600 CPU and Radeon RX 5700 XT GPU. All works well except my displays are very blurry and it feels like I’ll get a headache if I try to look at the screen for very long. The picture quality is noticeably worse than Windows or Linux. What can I do to fix it?
       
      --
       
      Let me start off by saying that this is my first hackintosh build. I based my build on the Opencore Vanilla Desktop Guide at https://khronokernel-2.gitbook.io/opencore-vanilla-desktop-guide/. I’m running macOS Catalina 10.15.4.
       
      So I finished installing macOS after slowly and carefully taking about 8-10 hours to go through the guide yesterday and make sure I did everything properly. It paid off - it has been solid as a rock. However, there is one problem that is currently bugging me to no end - my displays are very blurry. This seems to be independent of any application or display resolution. My dock icons are blurry, the system text is blurry, app text is blurry (like in Slack, Safari, Notes, etc). This does not occur in Linux or Windows when using the same screens. 
       
      Also, as a test, I hooked up my girlfriend’s MacBook Pro to the same two screens, and the monitors are crystal clear again, just like they usually are in Windows. This leads me to think that my EFI may be configured improperly or my system may be missing some software or a kext that enables the displays to show a sharp image. I attached my EFI folder and my config.plist file for reference. 
       
      EFI setup:
      ACPI: SSDT-EC-USBX-AMD.aml Drivers: ApfsDriverLoader.efi OpenRuntime.efi VBoxHfs.efi Kexts: AppleALC.kext AppleMCEReporterDisabler.kext Lilu.kext RealtekRTL8111.kext VirtualSMC.kext WhateverGreen.kext (version 1.3.8) My boot args are: "npci=0x2000 agdpmod=pikera keepsyms=1 debug=0x100 alcid=1"  
      System specs:
      Ryzen 5 1600, no overclock or anything special Corsair Vengeance Pro RGB RAM, 32GB total (2x16GB DDR4 dimms running at 2400MHz) XFX Radeon RX 5700 XT RAW II 8GB GPU (this is listed as a PCIe 4.0 GPU, could that cause issues since my motherboard is PCIe 3.0 only? Works great in Windows/Linux) ASUS Prime B350M-A motherboard Samsung PM961 256GB NVMe SSD  
      My monitors:
      Samsung U32J59x (32” @ 3840x2160) ASUS MX279 (27” @ 1920x1080) The blurry issue also occurs when I plug directly into my 58" Samsung 4K TV.  
      I’ve already tried these steps:
      Adjusting monitor “sharpness” settings, totally unbearable at “0” but still looks pretty bad even at “100” Trying a bunch of different resolutions in the “Display” preferences. On the 4k monitor, the only one that looks any better is the 1920x1080p option, but then I have far too little screen space left. Using SwitchResX, no different than using different resolutions in the regular Display preferences Using subpixel antialiasing in the terminal with no noticeable difference, even through reboots Turning on/off AMD FreeSync on my 4K monitor — if I turn on FreeSync, the display lags and stutters, and quality is not any better. Also tried turning on/off “game mode” but that had no difference. Tried switching DisplayPort version between 1.1 and 1.2 in monitor settings (on 4K monitor) Checking my BIOS settings, such as making sure CSM is off, against the OpenCore guide that I used to make sure everything was correct  
      Does anyone else have some other ideas that could help to correct this issue? Any ideas would be greatly appreciated. Thanks in advance!!

      I have been using clover to install and configuration my Hackintosh High Sierra 10.13.6. It's been a struggle and a pain. Can't restart/shutdown/wake from sleep. Random freezes. When freeze happens mouse works but in loading state. UI and open apps freeze not the mouse. I can make the apps smaller and move them.

      I haven't used any DSDT nor SSDT. Tried 5 or 6 of them from others but sometimes i end up not booting. Could someone explain me do i even need them and why? Do i need DSDT or SSDT or both?

      I'm going to try to install everything OpenCore. The first thing is i can't use a method that needs an internet while installing MacOS cause my ethernet/internet only works when i install MacOS. So i can't use the images i need full installation. Okay i have the full installation for 10.13.6. I need to use a version 10.13.4-6 versions cause application Sketch needs the newer one High Sierra 10.13.4++ version.

      Can you tell me? Can i use same kexts from Clover on OpenCore? Secondly how can i install full USB MacOS installer? (High Sierra 10.13.6 version i have is 7gb i think thats it)
      Is there a version of AMDHigh Sierra version made from the community for 10.13.4++ version?
      If i use the normal 10.13.6 High Sierra should i use this AMD 10.13.6 Kernel when i have installed the MacOS or some other kernel that's better for my system? https://github.com/Shaneee/AMD-High-Sierra-XNU/releases
      Whats the best version of High Sierra to use for Ryzen and Nvidia system?

      Will it be better to use OpenCore?

      Mortar Max B450M
      Ryzen 2600x
      Nvidia GTX 1060

      Hi everyone,

      I have run into a frustrating problem here.

      My hardware:
      MSI x399 Meg Creation
      2990WX
      64GB ram @2933Mhz
      Radeon 7
      Sata: Samsung 130GB SSD
      M.2: Samsung 970 Pro 1TB(latest firmware)

      Using OpenCore 0.5.6
      (NVMeFix NVMeDxe installed)
      I have successful installed OSX catalina onto my 130GB. It works flawlessly.

      and then I figure I should do it on my M.2 drive. It installs flawlessly, at the last stage of installation, it naturally restart and thats it.
      I can not boot into this newly installed OS on the M.2 drive. it keeps throwing: "error loading kernel cache 0x1"

      I have tried deleting the prelinkedkernel from recovery partition. Tried rebuilding cache(I have not installed any kext into L/E).

      All this time, I can use the same boot USB to boot into catalina on my sata 130Gb SSD working just fine.
       
      attached is my EFI folder. I have tried all the suggested SMBios iMacPro1,1 MacPro6,1 MacPro7,1
       
      is this ruled out that samsung 970Pro doesnt work?
      Please help.
