First and foremost thanks for checking out the guide, however I have been very busy and haven't had time to respond lately, so please accept my apologies for that.


Okay, how further?

What do you mean?

Hi,

Thank you so much for this guide.

I tried all step you mentioned but my sapphire 7970 vapor x ghz edition 3gb has different outputs than others =/

1xdp, 1xhdmi, 1xdvi_d, 1xdvi_i

decoder and decedo

and i tried the make code construction

Code:
12040501 dp
22050104 hdmi
11020603 dvi
10000306 dvi

Could you please help me for last step.

Place your constructed code in the template in post one and and then add it to your config in the kext to patch section post one has examples

I have followed this guide to create a connector layout that matches my MSI Radeon RX 560 video card. For some reason, when I put the patch in the config file, the system does not boot. I see the Apple logo and the progress bar reaches almost to the end but it never completes the boot. I used the Acre framebuffer as it matches my video card.

Code:
Acre (3) @ 0x622e0
DP, HDMI, DVI-D
000400000403000000010101000000001102020100000000
000800000402000000010200000000002103050400000000
040000000402000000010300000000000000030500000000

Here's my modified framebuffer:

Code:
000400000403000000010100000000001102020100000000
000800000402000000010200000000002103050400000000
040000001402000000010300000000001000030500000000

I created an entry for AMD9500Controller. Under Find, I put in the original framebuffer and under Replace I put the modified one.

Code:
<dict>
                <key>Comment</key>
                <string>MSI Radeon RX 560 Connector Patch</string>

                AwUAAAAA
                </data>
            </dict>

When I copy the framebuffer in Clover Configurator, should there be any spaces between 8 digit numbers? I also enabled ATI, selected Acre and RadeonDeInit.

Sounds like you forgot one step rebuilding kextcaches do so in single user mode with these commands
Code:
mount -uw /
touch /System/Library/Extensions/
kextcache -Boot -U /
exit
may need to do it a couple times

Hi, I would like to buy this card using dual dvi port.
https://www.asus.com/us/Graphics-Cards/R9270XDC2T4GD5/

I read the guide, but don't understand at all.
What's the process for using it in dual monitor?
I don't find any framebuffer in 7000.kext with the same output, what to do?

Thanks, and excuse my noobing.
Sometimes the dual monitor setup just works sometimes it doesn't and hence the need to patch the framebuffer. I think you need to get a better understanding of the guide before I dive deeper in to it here.

Why does running decoder in terminal result in this mess:

Looks like you didn't point it to your vBios rom file of your card.

What do you do if some of your values from redsock and redgate are hex values such as 0xFF ? That isn't a 2 digit number...

What do you do if none of the framebuffers in the kext for your card have enough connectors? Mine has 5 and the AMD8000 kext only has 2 framebuffers and neither are even close?

FYI - my card is a FirePro m6100. It's an MXM card.

Thanks!

Mobile cards are very poorly supported in hackintosh for which I have no suggestions

Thanks so much for this amazing guide. I am still digesting all this, but I would be most grateful if anyone could confirm one thing for me:

I am planning to buy a card such as the Asus 7970 DirectCU II which has 2 x DVI + 4 x DP ports. I then hope to use the following 5-monitor config: 3 x DP + DVI + DVI

Could anyone confirm that it should be possible for me to get 5 or 6 working displays on a 7970 which has 6 ports? I am worried that it appears that no reference/standard FrameBuffer has that many ports, at least not a recent one. The only one I can see on the Radeon Compatibility Guide which has 6+ ports is from 5xxx, a "5870 EyeFinity 6". Can I use one that old with a 7970?

EDIT: I've since looked through the 7000 personalities and see several that have six ports, but none with 2 x DVI + 4 x DP. I'm hoping it might be possible to patch to the required config.

However a bigger problem I didn't previously think enough about is the fact that I have no UEFI - I am on an X58/LGA1366 system with Legacy boot and no iGPU. The OP specifically states this is not supported for the patching method, so this may be my biggest problem.

I must say though I still don't fully understand the need for an iGPU in all cases, given that the real MacPro 5.1 uses LGA1366 and had no integrated GPU. It's possible to buy AMD 7XXX cards that specifically state they're for Mac Pros, eg a 7950. And in fact I could buy a refurbed MP 5.1 from a reseller which comes with an AMD RX 560.

So it seems to me that surely iGPU can't be a hard requirement in all cases? Unless this ia difference in Hack vs real Mac.

The reason you need iGPU/Nvidia Card is so you can boot to the desktop to obtain all this info to perform the patching, on non UEFI based systems. Now you can use a six port framebuffer for a five port card. You just must edit the first five ports in the framebuffer and leave the last one alone data length must still be the same.

No luck yet with the m6100. Here is a summary of my efforts if anyone has time for a suggestion. Please note the hot plug id of "ff" and the enc value of "0x10?". Very odd to me. If I made the "ff" decimal, it would be 255, and more than 2 digits... :(

Again mobile is poorly supported and I have no suggestions for it note this is desktop section of the forum.
 
Hi @carpentryplus25, I own a R9 270X and like most others suffering from "black screen" on High Sierra from DVI output, HDMI does work. I'm on X58 platform with legacy BIOS, the card is MSI with latest BIOS and yes that is UEFI compatible; is the guideline you given here going to work on my old good system?
 
Alright I processed the mod but encountered difficulties. My card is MSI R9 270X HAWK, with DP, HDMI, DVI-I & DVI-D.

[DVI_D]  11020105

I tried 2 mod on Namako and Futomaki but none is success. Still black screen on DVI, worse HDMI not working too. Please can people with more experiences help me to check if these patches are correct?

Hello @carpentryplus25, here is everything, thanks for looking into it.

Meanwhile I am using Futomaki without patch, but limiting output to 2 to get DVI working. This is just a workaround as other ports are not working under this circumstance.

Hello @carpentryplus25, here is everything, thanks for looking into it.

Meanwhile I am using Futomaki without patch, but limiting output to 2 to get DVI working. This is just a workaround as other ports are not working under this circumstance.

Patch looks ok. Have you rebuilt kextcache? If not do so via single user boot I had to do it a couple times before the kextcache was rebuilt properly. You may wanna try the secondary control flags mentioned in the guide. You may also wanna look into the black screen issues related to mac pro smbios. Also it may be needed to use the Namako framebuffer instead of futomaki.
 
Hello @carpentryplus25,

At the beginning I'd like to thank you very much for this guide.
With the recent security update I am not able to get a display on DVI and HDMI on my R9 280X. It worked fine before so I don't know what might have changed. I updated Clover to the latest version and also done all the steps again including rebuilding kextcache.

It used to work on all ports before update with a limitation of 2 monitors connected at the same time but after this update I can only utilise DP. I was also wondering if there's any way of getting more than 2 monitors displaying. That would be totally awesome.

I worked out my numbers for the framebuffer modification to be :

Code:
12040501
22050402
11020104
10000306

I've got 2 x DP, HDMI and DVI so I chose Dashimaki buffer to edit

Find :

Code:
Dashimaki (4) @ 0x59e00
DP, DP, DVI-D, HDMI
000400000403000000010101000000001204020200000000
000400000403000000010200000000002205030500000000

000800000402000000010400000000001102010100000000

Replace :

Code:
Dashimaki (4) @ 0x59e00
DP, DP, DVI-D, HDMI
000400000403000000010151000000001204050100000000
000400000403000000010261000000002205040200000000
000800000402000000010343000000001102010400000000
000200001402000000010433000000001000030600000000

I am attaching all files that would be required to troubleshoot so if anyone can help I'd really really appreciate it.

Once again many, many thanks !

Hello. I was hoping for some help. I have a Sapphire R9 280 that has DVI-L and DVI-D how should I be configuring the DVI-L as it shows up twice in the BIOS Decoder? I only have 1 monitor and only use HDMI to connect to my monitor but I want to have the FB configured correctly for the card. I have attached a zip that includes the output from both BIOS decoders as well as the Code Construction for the ports( transmitter,enc,etc). Thanks for the help!
