Help with AMD Firepro V5900 configuration in new Sierra Installation

Hi, I was hoping somebody here could give me some ideas on how to get my AMD graphics card working.

This is my first Hackintosh, and first time using Clover.  I have read this thread and also https://clover-wiki.zetam.org, but I have not yet understood everything.

There seem to be many different ways to fix this, but I have spent some time trying different things, which make no difference or break the display completely.  

 

OS: macOS Sierra 10.12.6

My HW:

Dell Precision T5600 with Intel C600 chipset, single quad core Xeon E5-2643 3.3 GHZ 

Graphics: AMD Firepro v5900 2GB (workstation card) Vendor 0x1002, device ID 0x6707 (Cayman, Lotus), set in BIOS to slot 2 (not Auto selected)

Current Clover configuration (v2.4k r4411 config via Clover configurator 4.60.3.3):

Boot: UEFI only ESP,  -v -no-zp, ncpi=0x2000, dart=0, debug=0x100, kext-dev-mode=1

Graphics : InjectATI, LoadVBios

SMBIOS: iMac14,2

Kexts : AppleIntelE1000e.kext, FakeSMC.kext, VoodooHDA.kext

Added drivers : EmuVariableUefi-64.efi, OsxAptioFixDrv-64.efi, HSFPlus.efi

Everything seems to be working with this config, but I have no graphics acceleration (eg v slow and jerky Launchpad overlays).

 

I edited 2 files because device ID 0x6707 was not present :

/System/Library/Extensions/AMD6000Controller.kext/Contents/Info.plist

/System/Library/Extensions/AMD6000Controller.kext/Contents/AMDLegacySupport.kext/Contents/Info.plist

Each time I changed the value 0x6704 (AMD Firepro V7900, Cayman, Lotus ) to 0x6707(My device).

I think that it was after these edits that the system correctly identified my connected display (Apple Cinema Display 23", DVI) and I was able to choose from multiple resolutions. ,where previously it was identified as a generic LCD and only native resolution 1920 x 1200 was available.  

I have tried using WhateverGreen.kxt/Lilu.kext.  This changes the EFI Driver version from 01.00.3180 to WEFR-116-2018-03-09 , but there is no noticeable improvement to performance.

Any suggestions would be very welcome.  

Also, where is the log file saved when kextlog=0xffff is specified in the boot options?  I can't find it.

If you still did not find a solution...

...you need to edit plist in AMD6000Controller.kext and AMDRadeonX3000.kext

Thanks for replying @yapan4, I'd almost given up on getting any help.  Maybe I should have posted in a different section to have more chance of an answer?

I already did edit AMD6000Controller.kext : Changed 0x6704(AMD Firepro V7900) to 0x6707 (My card, AMD Firepro V5900).

Here's the thing : In Yosemite the AMDRadeonX3000.kext plist file, there is a key/section for Cayman cards <key>AMDCaymanGraphicsAccelerator</key>, and inside it there is :           

 <key>IOPCIMatch</key>
            <string>0x67181002 0x67191002 0x67041002</string>

In Sierra however, this key has been removed, and the 6704 is no longer present anywhere in the AMDRadeonX3000 info.plist.

I imagined that they took it out the 0x67041002 because it's an old card (2011), so when I saw the file AMDLegacySupport.kext (file not present in Yosemite) I imagined that it might be there instead, and it is. So I edited that instead.

Do you have any other ideas for getting this to work?

No, sorry...
It looks like GPU Cayman (Radeon HD69xx, FairePro V5900 and V7900) is problematic in 10.12 x. Look for a solution for Radeon HD6970. If not, then I recommend upgrading to FairePro W5000 or W7000. or downgrade to FirePro V4900(Turks)
