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.
As h98 says, fw 0089 is fine.
I have RX580 with 2/3 displays attached, zero restarts in Sierra.
I do have an original 5.1 though, maybe a problem with the 4.1>5.1 fw!

Mine is an official 5,1. I looked up the serial number and it's genuine 5,1

Edit: I'm the original poster of this thread so mine was restarting.

First post here in this forum...being a lurker for a while.

Anyway, Installed a Sapphire RX 580 Pulse last week with a dual mini 6 to 8 pin in my Mac Pro 2x3,46 Ghz, so far no problems. Everything is running smooth in Mojave beta 7

Happy to hear it works right for you guys ! Thanks for chiming in.

I have an 8pin cable to dual 6pin, and I use for the moment two 6pin to mini 6pin cables from HD5770 cards of others MacPros.
I noticed a little thing on this Y cable : one of the 6 pin connector has only 5pin in it...

So everybody have an original 5,1 it seems. Maybe the problem come from the fact mine is an upgraded 4,1 to 5,1. I have spare original 5,1 MacPros, I'll give it a try during the day.

Just checking : My SMC version is 1.39f5

Any info about the Orinoco FrameBuffer ?

One more time, everything ok with just one screen. Will see what happen with a second screen today.

---
EDIT : 5 mins after connecting the second screen, restart...
When I connect the second screen I hear a fan running faster in the MacPro. Maybe it's just a problem with my cable, whichi s ok for powering the card with one screen but not two screens, as two screens seems to ask more at the RX580.

EDIT 2 : I saw reports of someone using an upgraded 4,1->5,1 MacPro running a RX 580 without problem.

One more time, everything ok with just one screen. Will see what happen with a second screen today.

The FrameBuffer is to define the port layout. The Sapphire PULSE RX580 should be good fit with the Orinoco Framebuffer.

But AFAIK, only the PULSE RX580 with part number 113-4E353BU-O4E or 113-4E3531U-O4V will be assigned Orinoco Framebuffer.

All other RX580 (including PULSE with other part number) can only have the generic RadeonFramebuffer.

I open a bug report in Apple, and have reply already. So, the Apple engineers may be working on it.

But anyway, my 49" 32:9 monitor can be use as 2x 27" 16:9 monitor. I connected both input to the PULSE RX580, and use it as two monitors side by side. Loading, temperature, fan speed all normal. No restart.

I have a 4,1 > 5,1 and have had up to 4 screens simultaneously. One of the screens would have been connected to a GT120 however. No issues with random restarts, or any other noticeable issues either actually.

Something is fishy, like crjackson suggesting possible piece of failing hardware, but it's not because of being a 4,1 or 5,1 cMP model.

Since you have two monitors. Obvisouly you already tried only connect monitor 1. Did you try NOT connect monitor 1, but only connect monitor 2?

My 5,1 was restarting randomly after upgrading to the RX 580, and it only seemed to happen in macOS 10.12.6 Sierra and it was fine in boot camp.

I'm running a 1440p 144Hz display via DisplayPort.

I haven't had a restart in a long time though even though I'm back on Sierra again. I did move my boot camp to a completely separate drive from my macOS drive though, but I doubt that's what fixed it.

@Jayson A : Now that you have upgraded the firmware of the MacPro (for Sierra or Mpjave), maybe the card is well recognize so no problem anymore even on Sierra ? My monitors are just 1080p 60Hz, on HDMI/DVI.

@h9826790 : Thank you for taking the time to set your wide screen as two screens and for these details ! I’ll check the part-number of the RX 580. And yes, I tried each of my two montors only, and my TV.

@skizzo : Thank you for ruling out the fact that a 4,1 MacPro would be the problem ! Happy to hear yo can run 3+ monitors at the same time without problem on a 4,1 MacPro :)

I maybe found where is the problem. I have bad feelings about the cable I have (8pin to dual BIG 6pin), and about this RX 580 itself.

As told before, the 8 pin to dual 6pin cable have one of its 6pin connectors with only 5 pins inside… (I use two 6pin -> mini 6 pin cables to make the link between the motherboard and the Y cable).
And it seems that the restart occur when the fans of the RX 580 starts spinning.
I let the side of the MacPro open, and put every fans of the Mac at 50% with MacFan, and for the moment everything is fine with 3 monitors. But the fans of the RX 580 are not turning for the moment.

However, since yesterday the DVI output has a color problem. I tried to connect 3 different screens with different cables, and every time the graphics are pinky (never saw a pink apple loading screen before ^^).
Strange thing, at the beginning of use of the RX 580, I had 3 screens with perfect color, DVI was fine. Then the restarts happened.

So it might be a powering problem : when the RX 580 has some « heavy » work to do (well, having a second screen for example), the fans of theRX 580 starts turning, which asks for more power but my cable is faulty so the motherboard can’t give enough power with just one connector, so the Mac shuts down for it’s own safety.
Having the MacPro open with all fans of the mac running at 50% is enough for cooling the RX 580, so the card don’t use it’s own fans and everything work even with 3 monitors. It does make sens.

OR, the card is faulty, that’s why I have a pink screen, that’s why i have restarts.

SO : Until I receive the cable (express delivery from modDIY -> 30€ ouch) with should be here between 2-5 days, i’ll return the card to Amazon because of the faulty DVI, and ask for a new one.

Just to be sure i’ll put the card in an original 5,1(under sierra) to see if I have the same problems (restarts and/or pink DVI).

If you want to monitor the GPU parameters, this automator workflow can do it.

Just unzip the attachment, double click it (automator should open automatically with the workflow loaded), then click "run" on the upper right hand corner.

The View Results windows will display the GPU parameter and update every 2 seconds. (Note, that Total Power is NOT the GPU's power consumption but something else. So, don't worry about it)

That missing pin is completely normal. I have a dual mini 6 pin to 8 pin cable and I also tried using 2 mini 6 pin cables attached to a dual 6pin female to 8pin splitter cable and had the problem both times.

Also, I noticed the random restarts would happen when I wasn't even hardly doing anything... just browsing the web. Nothing that should be stressing the card too much. It doesn't happen in Windows though where I stress the card A LOT.

First of all, thanks h9826790 for the automator workflow, it allowed me to investigate further…
(Also, under Sierra it only displays the device utilization)

Interesting informations Jayson ! I might cancel that 42$ command on modDIY for just a cable...
And indeed, you already told us about your intense use of the graphic card under Windows on your cMP and everything was fine. It should have made me think my theory was wrong.

So, I made some more tests ! It seems that, IN FACT, it’s just an overheating problem…

I stressed a bit the card (around 30% use), with 3 monitors (whose one pinky…), and the Mac’s fans at 50% spinning using MacFan. Everything good. The card’s fans where not running, so I stressed it a bit more (around 40%), everything good, and the card’s fan where spinning too around 17% of their max speed.

I put all the Mac’s fans at 100% (trying to use a lot of power). Everything good. The card’s fans stopped spinning (logic). Stable, no restart.
Card was around 45°. Was 47° when Mac’s fan at 50%.

Then I put all the Mac’s fan back in automatic mode, and exit MacFan.
After 10 mins, restart. Saw the card temperature at 53° before restart.

—> Also tried the card in an original 5,1 cMP. Same problem ! After 10 mins, restart.
So I put the fan’s of the Mac at 50% with MacFan, I thought were was no problem but after half an hour, restart…
I’ll incriminate the fact that the system of the 5,1 cMP is Sierra, with classic Sierra firmware.

SO it’s seems it’s « just » an overheating problem !

Second thing : the image of the DVI monitor is not pink anymore in this 5,1 Sierra MacPro.
So the RX580 is maybe not really « broken » as I thought it could.

I think tomorrow I’ll give a try to the firmware of Mojave.

I saw that Jayson’s working fw is MP51.0084.B00, while the one I have with High Sierra is MP51.0089.B00, even if h9826790 said he used this one without problem.

Currently, under Sierra in the 5,1 with Mac’s fans at 75%, no problem after 35mins.

Well, off work for today ! See you tomorrow guys ! And thanks !

I was having restart issues when I only had 1 6-pin to 8-pin connection to the RX 580. I switched to 2x 6-pin to 1x 8-pin and no more restarts.

You absolutely need dual mini 6-pin to single 8-pin to power the card. Not at all shocked at issues with using only one 6-pin cable.

If I read his post correctly. He has

a) 2x mini 6pin - > 6pin
b) dual 6pin female -> single 8pin

And he use this cables combination to power the RX580

TBH, 53C should be way way below overheating. Just curious, did you remove the backplate?

And if you have Windows, You can simply boot to Windows and see if tis restart issue still happen. (You can also has better GPU monitoring in Windows as well).

That combo fully works. Was powering GTX 1080 FE for a few weeks that way.

The post above notes only one 6-pin cable and restart issues.
I was having restart issues when I only had 1 6-pin to 8-pin connection to the RX 580.

Maybe it is a faulty cable or mobo connector.
Could he try unplugging one 6 pin with one monitor connected, this should still work with just desktop surely?
It may show that one 6 pin actually doesn’t work, whether on the mobo or cable?

OP stated he put the card in a different cMP and it did the same thing. This should show the problem is not isolated to his cMP. See quote below.

—> Also tried the card in an original 5,1 cMP. Same problem ! After 10 mins, restart.

He may still have a faulty card IMHO. OP should document EXACTLY how he "stressed" the card so others can verify that this problem is unique to his particular configuration. I agree it sounds like a heat related issue, but it tends to make me believe the heat issue is with the card.

Without further testing details, it's just a shot in the dark though. My 0.02¢

Also OP, I assume you have the card in Slot 1, mine is in Slot 2. Slot 2 will have more free airflow around the card. You may want to try this since heat seems to be an issue.

I don't have any restarts, but it would be nice to be able to control the fans on the RX580 like we can with Mac fan control for system fans. I wonder if anything like that would ever be available for a Mac to control the AMD fans

Ah sorry I missed that, still could be a faulty gpu cable then........:)

AFAIK, no software can do that in macOS.

However, it's possible to mod the ROM's fan profile.

When my macOS was restarting, I wasn’t stressing the card at all. I was doing some web browsing and also it didn’t take long for the restart to happen.

Since the card works perfectly in windows (I even ran some benchmarking utilities like fur mark and uengine) and it was fine. No instability there.

The other thing to note is I was getting restarts under macOS Sierra, so I tried a clean install of Sierra which didn’t work, then I updated to High Sierra which seemed to cure the problem. However, I put Sierra back on the same partition and the restarts started happening again. So then, finally, I separated my Sierra drive from my boot camp drive and haven’t had a restart yet with this config.

It’s also worth noting that I don’t spend much time in macOS anymore, but from the times I was using it, it seemed like smooth sailing.

I don’t think the Mac firmware is the key.

Also, for what it’s worth, I have 2 different ways to power the card and both ways did the same thing. I have 2 mini 6pins to 6pin cables connected to a dual female 6pin to 8pin splitter. That’s the first way. The second way is by using a dual mini 6pin to 8pin cable. I tried it both ways so I doubt it’s the cables.
