Window Server crashes regularly after installing RX 560

I have a 2010 Mac Pro running High Sierra with a Radeon 5770 in slot 1 but I saw that I would need to get a metal capable GPU to upgrade to macOS Mojave when it comes out.

So I got an RX 560 since that was one of the cards Apple recommended and installed that in slot 2. Ever since installing that I regularly get Window Server crashes. Both of my displays go blank and then it brings me back to the login screen.

Is anyone else experiencing this? I can't tell if this is a software issue or an issue with my particular hardware. If it is an issue with the actual graphics card then I would like to exchange it soon before the return policy runs out. I've attached one of the crash logs and I also created a bug report with Apple.

Example of one of the crash logs: https://gist.github.com/aaronraimist/dfeef94187eb1175ecb592a87909fe07

It is always KERN_INVALID_ADDRESS at that exact address: 0x0000000000000104
 
Can I ask you why you installed the 560 in slot 2 rather than slot 1? Are you keeping the 5770 installed also?

For troubleshooting purposes, you should try a couple of things:

1. Completely remove the 5770, move the 560 to Slot 1. Boot and see if you continue to get crashes. If so, then you may have an issue with your 560.
2. If not, then try leaving the 560 in Slot 1 and put the 5770 in Slot 2 and see if the crashes come back. If not, then just leave everything the way it is. If they do, then at least you know the problem relates to the combination of cards and is not a defective 560 card.

Edit: Also, what version of HS? 10.13.6?
 
Well I installed it in slot 2 because my understanding is I need the 5770 for the boot screen. I'll try those suggestions later today and will report back.
 
Also, see this post: #359

Remarkably similar-sounding issue and he was using a GTX 680 (unflashed) in Slot 2 and a 280x (not sure if it was flashed with the EFI ROM) in Slot 1.
 
Funny, I have the nearly the same problem. But since I`m already on the Mojave Beta I thought it is a bug in the beta.

I have the MSI RX 560 installed in the top Slot in the bottom Slot is a RX Vega 64. The RX560 is driving a Vertical monitor wir Full HD and the Vega a 40" 4K...

It goes black and starts the login everytime I push windows between the two Monitor,try to change Monitor settings etc.

Before I had the same configuration with a HD5870 instead of the RX560 and everything worked fine.

It is a quite strange behaviour...

Yeah its almost the same problem except there is no specific action I'm taking that causes it to crash. I can change window settings or move windows between monitors and it all works fine until it randomly crashes usually when I'm just in the middle of typing some text.

Is your crash log basically the same as mine?
 
I can confirm that there is an issue caused solely by having certain cards in slot 2. I ran a flashed R9 280X in slot 1 driving my primary display, and an unflashed GTX 680 in slot 2 driving my secondary display. This was running Nvidia web drivers for 10.13.6. The login screen loop would occur in this case. I just tried taking out the R9 280X and putting the GTX 680 in slot 1 by itself running both displays, and it booted up (no boot screen) and is NOT stuck in login screen loop.
[doublepost=1531677445][/doublepost]I tested the GTX 680 and flashed R9 280X in slots 1 and 2, respectively, as well as reverse order. In both instances, whenever the two cards are hooked up (I tested a fresh user account as well) the machine is stuck in a login screen loop with no escape. The GTX 680 works fine when it is by itself with nothing plugged into slot 2.
 
Didn`t look at the crash Log yet. But I will try a few different setups and maybe also try what happens, if I connect everything just to one card...

I let you know if things are changing...

But it`s good to know, that it not only happens with the Mojave Beta.

Also I thing that thoose things started to happen since I put in one of the Apple recommend Cards for Mojave...
 
Right now to get around the issue I'm just running the RX 560 (in slot 1 now but that doesn't seem to make a difference) with one display plugged in. I left the Radeon 5770 in the Mac Pro as well with no monitors plugged in to it which seems to work fine. I can plug the second monitor in to the 5770 for the boot screen if I need to reboot.

I assume (If I had the right adapters) I would be able to run both of my monitors off the RX 560 and it wouldn't crash but I don't know that. Seems like it is a software issue with running monitors powered by different graphics cards.
 
I can confirm that :) I put all my monitors on my RX Vega (slot 1) and attached no Monitors to the RX 560(slot 4) but left it in. Everything works fine now. At the moment I'm quite busy so I can't check other scenarios but I will try that out as soon as possible.
So it looks like everything works fine with the card in Slot 1.

Funny is with the RX Vega (non MAC Card in Slot 1) and the HD5870 (Mac Card in Slot 4) it worked perfectly having one Monitor attached to each card. But with the same Slot configuration and two none MAC cards there are problems...
 
How are you guys powering your TWO GPU's in your cMP's ? External PSU for the newer cards ?
The RX Vega 56 in particular has a TDP of 236 watts. The Vega 64's TDP is 334 watts.

cMP's will shut down when power demand is exceeded.

External PSU in the Optical Bay for the RX Vega 64 with 850W :) Should be enough ;)
