Okay, having followed a few instructions from elsewhere in this thread, I find the card is running at about 48-52 degrees at idle. The fans come on at 52. Is there a way to edit the kext to keep the fans on a small amount all the time, say 10 percent? I think that would stop the fan cycling while I wait for Apple to pull their thumb out and fix the drivers.
Got a tip for us?

Thanks for the link. I knew I saw a reference to that in here somewhere, but for some reason when I went back to find it, I couldn't. I'm getting old and feeble, I guess.
I think I found what I need to add on this page:

I'm having a lot of permissions issues, though, trying to add that in and then execute the 'touch' command afterwards. Could someone with patience explain to my aging brain what I need to do, preferably without the need to use nano or vi?
Thanks
You should able to upgrade to 10.13.5 via appstore update with the RX580. It's OOTB supported, the whole process is native.
However, it seems there is a firmware upgrade in the full installer.
So, if you download the full High Sierra installer to "upgrade" (not the combo updater, but the full OS installer). Then it may ask you to perform the firmware update first. In this case, the original GPU is required.
I am still waiting my CCC backup to complete. But yes, it looks like a new firmware is included.

Use Kext Utility (or similar) to install the modified kext.
Thanks. I'll give that a go. In the meantime, I'm waiting on the 10.13.5 update in the futile hope it will fix the driver situation with this card.
I figured out which driver isn't loading in 10.13.5 (and 10.13.6 beta) for HDMI audio. It's the AppleGFXHDA.kext. I ran "sudo kextstat" in Terminal.
I just used the App Store and updated to 10.13.5, got an RX 580 in my system, seems to all be fine.
You need to install an EFI GPU to apply the firmware update from the full installer though.
Well, after numerous failed attempts to update the kext to stop shutting the card's fan off entirely, I had a rare moment of clarity. I Cmd-tabbed myself out into the real world and opted for a hardware solution instead. Since the card was hovering right around the point where the fans were pulsing on and off, I just got some string and hung a quiet, slow turning fan, powered off an unused sata connection, over the card.
With a small fan speed controller I had in my parts pile, I adjusted the fan up to the threshold of audability. The card temperature is now sitting five degrees under the trigger point at idle. The best part is I don't have to worry about keeping a patched kext maintained through updates.

Many people stopped shitcoin mining because they couldn't make money. I told people last Fall and they didn't listen because they didn't want to learn that the difficulty rises with more miners and the profitability goes straight down. They bought all that hardware and destroy our climate to chase stupid pyramid scheme dreams.
I totally agree. Complete waste of resources and bad for the environment.
I just noticed the RX Vega 56 Nano is available now. Priced $449 at Newegg.

going a bit off the deep end here but i wonder
what is the Port configuration for this frame-buffer?
I wonder if Apple is planning to release a Radeon Pro 580 for the MP5,1? Proper mac edition cards have not been on the market for yonks now so if Mr Typical Apple guy wants to upgrade his Mac Pro 5,1 to a Metal card to run Mojave is Apple really going to leave them in the dry?
especially as the Mac Pro 5,1 does make a good development platform if your targeting users who run eGPUs on their modern TB3 Macs.
the other option I could see Apple do in this regard, is officially endorse certain PC video cards to operate in the Mac Pro 5,1 like they did with eGPUs, the only thing is I wonder how they would handle the no Boot Screens thing since in an eGPU setup the PC eGPU is never the only/primary video card/Display output device so they dont have to worry about that there.
interesting times ahead thats for sure
How do you find the port configuration for the framebuffer?
That's a really interesting theory. It may indeed be a new custom Apple card for the cMP.

try using this tool https://www.tonymacx86.com/threads/apple-intel-amd-ati-framebuffers.112299/page-4#post-1640375
(just save the code as a .php file and run in terminal php name-of-file.php and it will list all the frame-buffers like so)
if the new frame-buffer that popped up has something like DP DP DP HDMI then it could well be a PCIe video card of some kind
(if its just like 6 DPs then its probably some iMac or MBP card)
Thanks for the video. Yeah, it runs pretty warm. It sounds like the fan gets loud too. I guess you wouldn't want one of those unless you were determined to fit a Vega in a mini-ITX case.

Okay, thanks. I'll try it. I deleted my 10.13.6 partition when I was doing some backup functions. I'll reinstall it.
