I hope I'm not derailing the thread too much, but I'm having some weird issue with my Pulse RX580 8GB. I was lucky enough that its part number was close enough to the official "blessed" version that I didn't have to modify anything, it's assigned the correct framebuffer out of the box. Great. But when booting into Windows 10 I get no display output at all until I remove and reinsert the Displayport cable. Same with DVI. HDMI appears to work fine however, so it's not really a huge issue. Has anyone come across this before?
I thought it might have been just an issue with the individual card I had since I bought it used and it had been used for mining cryptocurrency, so I bought another one new on Amazon and it has the same exact issue. Luckily the part number is still good so it still works great in Mojave with no modifications needed.
Another interesting thing about this second card is that it has a switch on the PCB to change from "Gaming Mode" to "Compute Mode". I can't find any reference to this anywhere, I'm guessing it's a fairly new revision? Is it effectively just switching between two different BIOS? I only installed the card last night and haven't had much time to mess with it beyond making sure it actually works.
Flip the switch in the other direction and see if that works better for you.
Mine is on DVI and I have no trouble switching between Mojave & Windows 10. Strange issue...
That's the V2 card. Has dual ROM.
Sorry, can't help about your issue. My RX580 works really well in both MacOS and Windows with DP 1.2+ connection.
Is your RX580 installed in slot 1?
Did you try another monitor or cable?
it shows PCI-E speed only 2.5 Gt, and no one of 2 Display Ports work, only DVI and HDMI ports, and is a problem for my 3-monitors configuration
I think the Link Speed is only solved in the 220.127.116.11 or 18.104.22.168 BootRom. Since you're still on 10.13.6 you'll only get 2.5GT/s. That's what I'm getting on the identical card you have.
Try the card again, but try a different DP cable. When I first tried my card, I wasn't getting ANY video from either HDMI or DP. I think it was the connections.
Was the 10.13.6 a clean install or an update of an update?
What bootrom is on your system?
I would give a clean 10.13.6 a try.I updated Boot Rom to the last one from 10.13.6 - no changes, no one of 2 DP's work... Does it make sense to reinstall the system to the blank SSD?
You're better off upgrading to Mojave which offers far better support for the RX 580. High Sierra RX 580 support is weak.
You can correct the PN, following the guide in the first post of this topic. MacOS doesn't "see" a difference between a PULSE and a NITRO+. Just RX580 and PN.On Windows 10 works perfectly, on Mojave only works with igpu because RX 580 Nitro+ not supported natively.
I am very frustated with this.

The RX 590 is expected to be released on November 15th. I would wait and see if that pushes the price down.
Might also be worth waiting to see if the RX 590 works in a Mac Pro and what the cost/performance is compared to the RX 580.
