As soon as I installed 10.12.6, the reboots started happening again within minutes.
I guess I have no choice but to use High Sierra.
I bought a Sapphire Pulse RX 580 on Wednesday, plugged it in with the dual mini 6pin to 8 pin adapter and am having the same random restarts on 10.12.6. It seems the PN of the card has been changed to 299-1E387-000SA.
I can't install HS as I don't currently have an bootable Apple EFI supported gfx card for the firmware update.
Bit bummed tbh.
1) Join the 10.14 beta tester programme
2) Download the latest 10.14 beta FULL installer
3) Run the installer (it will NOT install 10.14, but trigger a firmware update do NOT need Mac EFI GPU)
4) Follow the on screen instruction to update the firmware to 138.0.0.0.0 with your Sapphire PULSE RX580 (the screen will stay black, but the super drive tray will eject to indicate that the firmware update is in progress)
5) Wait until the cMP auto reboot back to desktop
Now, you can install High Sierra if you wish.
Thanks, won't let me, says I need to be running 10.13.6 before I can run the installer.

If you can't get an EFI GPU in anyway, we can circumvent the need for one with ROMTool.
1) Disable SIP
2) Dump your BootROM with ROMDump
3) Compress and PM me your BootROM dump
4) I'll extract your Mac Pro identifiers from the BootROM and insert on 138.0.0.0.0
5) Put your Mac Pro in Flashing Programming Mode
6) Upgrade your BootROM with ROMTool
The dependency on EFI GPUs was caused by the old progress bar display, Flashing Programming Mode has nothing to do with EFI GPUs.
Yes, once in Flashing Programming Mode, you can use ROMTool to flash, but ROMTool is dumb. You can't update your BootROM, it will fully wipe and fully reprogram it with the ROM that you select. So, you need to add the Mac Pro identifiers to the 138.0.0.0.0 BootROM first.
P.S: Never use ROMTool to flash LOCKED.fd files without having a BootROM dump. You never log in iCloud/iMessage/Facetime again if you flash a BootROM without the identifiers.
Yes, both will work to update to 10.13.6, but none will work with Mojave.Thanks all for the info, I've asked a friend close by if I could borrow his 5770 Apple card, failing that his older 2600XT card which hopefully will also work? Both have EFI bootscreen support.
Thanks, good to know. Once I have the firmware update done I'll pop the RX 580 in.
sudo /Applications/Install\ macOS\ Mojave\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/UNTITLED && echo Mojave Installer Created
9) it will prompt you for the firmware update, just go ahead and select Shut Down. My machine would not shut down, after giving it a few minutes (wasn't sure if it was writing the firmware to a location so gave it time), I selected 'Shut Down' from the drop down menu.
This step never worked with my Mac Pros, some people reported that didn't work with theirs too. Glad that it did work for you.

Many people reported only a force power off to exit that screen. Also, some of the same people reported a big silver brick on their desk afterwards.
Basically, it's what you did - when you couldn't shutdown with the createinstallmedia pendrive.Not sure why anybody would force shut down with something as sensitive and fundamental as a firmware update! :/
Ok, I've missed about the part that you got it shutdown with the menu. On my Mac, it just keeps on the shutdown screen forever.Um, say what? I shut down using a menu, I didn't hold the power button down to force power off. The installer quit normally after shutting down from the menu and the machine did a soft shutdown.
edit - anyhow, it worked for me. YMMV.

The soft shutdown never worked with my Macs when updating via createinstallmedia pendrive and did not work with other people, I've posted about this when MP51.0085.B00 was released. People posted about that too, but some got it working like you did. So, maybe it's something about how the Mac is configured, model, etc.

Hey Guys,
Just made an account to MacRumors, this is my first post, youpi !
With that being said : I'm experiencing the same problem as you. Bought a Sapphire RX580 Pulse 8Go last week for an updated MacPro 4,1 -> 5,1 at work, and i'm becoming crazy !
- Random restarts while being on Sierra 10.12.6.
- Upgraded to High Sierra 10.13.2 with the help of the good old GT120 for the firmware update. --> Still have random restarts.
- Update to 10.13.6 --> Still have randon restarts.
- Erased SSD and fresh install of High Sierra 10.13.6. It asks for a firmware update this time too... Well, okay. Firmware update, install. --> Aaaand I just had a random restart ! Grrr !
So if I understood well, the solution would be to install the BootRom firmware of Mojave ? I'm currently on MP51.0089.B00. I'll try the Mojave BootRom.
I don't know for you, but it seems that the restarts occure when i'm having two or more screens plugged to the RX 580. I have just one screen currently and 40 mins without restarts. I'll try to stress a bit the RX580 to see if the restarts occure.
Anyway, thank you guys, this thread helps a lot ! I wanted to tell you, that's why I made an accout.
See you soon.
Sorry to hear that. May I know if you have Radeon Framebuffer

Or the Orinoco Framebuffer?

0089.B00 should makes no difference. I used that with my RX580 until 138.0.0.0.0 release, perfectly stable.
It seems that I have Orinoco. Don't know what's this Framebuffer, i'm gong to google it.
Also, I see that like me, the slot-1. (where is the RX 580) is listed twice. Once with "Audio Controller".
But next to that, I have no driver installed, while it seems you do have one (driver installed : Yes).
Could the problem come from that ?
Thanks for your help !

Edit :
Well, I'm off work for today, but here is something strange that arrived before I leaved :
The system was running for one hour with me installing software, with an online game running at the same time (which usually is quite using the graphic card when in retina quality).
Everything was fine. I launched Pro Tools with a big session and video track, everything good.
But I was with just one screen plugged to the RX 580. So I tried to plug the second hdmi screen, and as soon as I plugged it, the screens became black, keyboard Shift led not responding, and the mac disappeared from the work lan. So looks like a shutdown but the Mac was still running, no chimes, no restart.
So it's definitly the multi-screen which is causing troubles here!
