based on GPU 216-0810005 - 6850M datacode 17 with 2048 mb or 2Gb video memory
This card was implemented at the end of 2017,  supervised this card only one person.

in general this is a valuable experience.
it can be useful to all who wish, extend the life of your imac.  .
Rominator,  special thank for your work, and a significant contribution to everything.  .  

At the moment, work is underway to upgrade the 6970M video card with video memory expansion to 4096.
you will be the first to know about the results.  whether it's good or bad.  .

There is still a space plan, at 8970M which speaks of itself "- I can work in imac", in theory everything indicates this.  for example from

AMD7000Controller.kext - device id 68c1.

so intresting that, FrameBuffer is - pitcairn

How do you think Rominator, EFI part from Desktop Video Card "Pitcairn" theoretical can be approached?  and whether it will be necessary to edit the device id already in the Decmpressed EFI part.

6750M MXM card with 2GB doesn't exist so it's a fake 2GB
 or the russian guy changed the VRAM on the board and modifiy the PC bios.
That's is impossible to do for most of technicians in the world.
