Need MaciASL.app to edit .aml file.
In 100 and 200 series mobo, normally use peg0 for DGPU.
Attached files, ssdt-67381002-fb with framebuffer, another without, rename to ssdt-?.aml and place it to

/EFI/CLOVER/ACPI/patched/

Try without framebuffer first.

Friend, thx for help!
File without FB doesn't work.
File with FB works, but only with my first display, a second not work. The second display doesn't appears in window "About This Mac", only the first.
May be something else? )

If your second display is connected to 2nd DVI port, it may not work, is a known issue, see below link

Me ElCapitan works good with 2nd DVI port.

• Pithecia
• Bulrushes
• Cattail
• Hydrilla
• Duckweed
• Fanwort
• Elodea
• Kudzu
• Gibba
• Lotus
• Ipomoea
• Muskgrass
• Juncus
• Osmunda

This FB's don't work.

I compared two clover configs, ElCap and Sierra.
In ElCap I used a 0x68391002 fake ATI ID and some kext patches.

But, when I try to set the 0x68391002 fake ATI ID in Sierra config, I have a kernel panic (look the attachment).

Your ATI connector patch no longer work in 10.12.5, Baladi framebuffer data has change, same as Duckweed, also 0x68391002 may not suitable in this version.
My suggestion is use 0x67381002 boot up, download AMDFramebufferUtility.app to check BIOS framebuffer data of graphics card, how many ports, ports data and ports sequence order. Then decide to choice which ID, framebuffer name and create new connector patch to match ports layout.
