Its been a month now since I have started creating my workstation. So far everything else in my system has been largely plug in and play without much trouble the only thing left to do is get my Sapphire rx580 Nitro+ running.
It should be noted this card was purchased second hand on ebay, (I knew the risks). Part of my task is to validate that this card actually works which is tricky on a customac build. I have been working on using a backup linux os for recovery and also to validate that the card works. The goal of this build is to create 3D graphics and also to code personal projects.
Relevant info:
Smbios: iMac 14,2 (default from multibeast)
OS: Sierra 10.12.6
PSU: 650w
Manufacturer: Sapphire
HDMI is my only option
TLDR
Here are the results so far:
Scenario 1
Given I have No kexts
When I Boot
Then I get 60% through Apple progress bar booting then GPU stops making noise, fans stop and I get no signal.
Scenario 2
Given I have whatevergreen and lilu @latest. with igpu in bios set to pcie
When I Boot
Then I get 60% through Apple progress bar booting then GPU remains alive with a black screen
Scenario 3
Given I have multibeast Sierra and install whatevergreen and lilu @old_versions with igpu primary
When I Boot
Then I get a working Sierra
And my GPU works
And the display is bright
And Card is recognized as amd Pro 580
And performance is okay
Scenario 3 updated 16/01/2019, overall I'm happy that the card is functioning, but now I can do better. I want to move up to High Sierra. By the way I am taking an interactive approach. If I jump straight to my desired goal, I won't have learned anything.
I am very rusty and so you can count me as a partial newb in need of some help. I would be very grateful for any assistance but will use this regardless to track my results and hopefully help somebody in need. The rx580 appears to work for most people so I am trying to find the caveat.
