gigabyte r9 290x 7mb vram

[maxrainy]

Hi!
I've seen other threads, but for me there are no solutions, and it drives me crazy.
as you could understand, i got AMD 290x 7mb vram on sierra. I tried so many different ways but still no results - fb names, smbioses, fake ids, edited amd kexts, clover flags and patches.. mb you got your own guide to fix it - go ahead.
btw my monitor is 27' but sierra thinking its 30,5'.
with hd4600 and unplugged 290x sierra works perfectly (as iMac 15,1).
here is my last config.plist
help me pls

Try this config.plist
Make sure that you have disabled integrated graphics in your BIOS settings - Set PEG as primary.
Use a digital connection - DVI or HDMI - VGA is not supported.

still the same.

currently i'm using dp. dvi works but nothing changed.
hdmi don't work at all - no signal. have no idea why, notebook+tv with this hdmi cable works fine.
now Sierra don't recognise vcard but still 7mb lol
there is physical toggle on 290x-card for preset quiet or boosted mode. will it change anything? I think I'm using boosted mode
