nVidia web driver users, hold off on the High Sierra Supplemental Update

[SolidCake]

I wondering if that would conflict with the card that's already in there. Say that I put the GTX 1060 back in and installed the AMD drivers... would I really be able to then just pop the AMD card in later and have it work? I feel as though the AMD driver-installer would have to detect an AMD card.

Generally speaking, there are a lot of variables to consider given your circumstances. It could be a defect in your cards but it could also be something else. I have Windows 10 up and running so I'll tell you how I got it to work in my 4,1 -> 5,1.

When installing Windows 10 I used my stock GT 120 and a DVD of a bootable Windows 10 installer. I could not get it to install Windows 10 from a USB, or preloading the image in OSX.

I got the SSD ready via Boot Camp in OSX, inserted the DVD in the optical bay and shut down the cMP.

I powered on my cMP holding down "c" and the Windows 10 installation went smoothly from there.

Once Windows is installed you can boot back into OSX/macOS and install BootChamp. This allows you to restart into Windows if you don't have a boot screen. When you're finished installing Windows you can go ahead and install the latest AMD drivers and install your RX580 again and enjoy it in windows.

If you encounter any issues when installing. You can reset your PRAM on startup by holding down command⌘ + option⌥ + P + R until you hear the second beep. I remember doing this a couple of times during the Windows 10 installation as it would not boot back into OSX when the Windows 10 installer required a restart.

Good luck!

Thanks for that! I did - indeed - manage to get things to work, by borrowing an adapter and using my GT 120 to install the AMD drivers whilst the RX 580 sat within the machine. NOW, however, the RX 580 doesn't give me a picture unless the GT 120 is in there, headless. When I remove the 120 and boot, it's as if I never installed the RX 580's drivers in the first place. So curious...

BTW, @SolidCake, how do you get back into OSX, from Windows 10? I've heard that it's not as easy as things have been with Windows 7. Are you able to successfully boot back into OSX by selecting 'Boot into OSX' within the Bootcamp control panel? (Note that I have no bootscreens, so I cannot necessarily hold down 'Option,' unless - perhaps - I memorize the drive order.

Depends, if your HS is installed on a HFS+ partition. Yes, the Windows Bootcamp apps should work.

Howeve, if that’s installed on a APFS partition. The answer is NO. Without bootscreen, the easiest way to switch between MacOS and Windows 10 is via “BootChamp + SIP disabled”.

Or you can keep a 10.12.6 inside your Mac, so that you can select boot back to 10.12.6 inside Windows, then further select 10.13 inside Sierra. But I don’t think it’s easier than the BootChamp method.

Or it’s possible to hold Command + R during boot to get yourself into recovery partition. So that you can select High Sierra as the next boot drive. But again, I don’t think it’s easier. Also, in some scenario, the Command + R won’t work when Windows was set as the next boot partition.

Thanks for the info! I'm going to keep Sierra for a while. I'll be trying Windows 10 on my Bootcamp drive - either upgrade or clean installation.

Do you have OSX and Windows on different drives? I don't get the boot screen upon startup but that does not have to be an issue as restarting from Windows automatically boots to OSX. This makes restarting windows a chore as you would have to launch BootChamp from OSX to get back into windows. But I don't mind that. If you really need a boot screen I can recommend installing a stock GT 120 and having it go to a separate 1920x1080 monitor. This enables boot screen on that particular monitor.

Yes, I have Windows on another drive. I select my Windows disk from 'Startup Disk,' within Sys Prefs. In Windows, I select my OSX disk through the Bootcamp control panel.

Anyway, if I can do the same with Windows 10 (Sierra / HFS), I'll be happy. Now, I just got to get a hold of a DVD for my Windows installation.

When you installed Win 10, did you go all the way through the Bootcamp setup, or did you use it only to designate the Bootcamp disk? Also, when the system reboots several times during the installation, does it return to Windows properly, with a non-EFI card?

(I think, BTW, that I'll first try installing Win 10 with a different EFI card, such as the Radeon 4870. Then, I'll put in the RX 580. As for the GT 120, I am not risking putting that back in, unless I am using OSX. If neither EFI card works, I'll try just doing it with the RX 580 in there.)

OK, having windows on a separate drive, SSD preferably, is the best way to go about it IMHO.

I used BootCamp and formatted the drive for a 64-bit Windows install. It then goes to format the drive and install the needed Windows drivers. I did not use BootCamp to preload or pre-install Windows. This was a while back so I don't know if the process has changed up until now. I do remember it taking a while.

When BootCamp was done with preparing the drive I loaded the Windows 10 install DVD and shut down my mac. Upon starting up I held down "c" and went through the Windows 10 install process.

They key for me to get this to work was getting a Windows 10 install DVD. I tried preloading the ISO and making a bootable Windows 10 install USB but none of those worked.

If you get stuck in boot loops or any other issues you can try resetting the PRAM as I mentioned before.

IIRC the install process is done in one boot sequence. When it's done there's a reboot for Windows 10 account activation but you can boot into that via BootChamp in OSX.

How much power does your RX580 draw? One thing to note is that without any AMD drivers Windows can pull a lot of power form RX480/580 cards. There were instances of cMP's shutting down on Windows boot because of GPU power spikes.

Thanks for that info! Will definitely help when I go to do this. Not sure about the power draw being too high. Without the drivers, the only thing the card was doing was blasting its fans. Haven't had a shutdown happen.

Just making sure: you left this option unchecked and simply downloaded the drivers + formatted the disk? In other words, you let Bootcamp do the formatting and downloading of drivers, but you technically installed the OS in a Bootcamp-less manner? Sorry to re-state anything; I just want to make sure I know exactly what you did.

I'm going to be installing to a separate SSD in a separate drive bay - not my main disk. I am also assuming that I will not have to boot back into OSX until the Windows installation has more or less completed (save for account creation / driver installation), as I'm going to be removing every other drive before installation. (When initially installing Win 7, I learned the hard way, by leaving my OSX boot drive in there with it. Windows took over my entire boot manager and bricked the OSX drive. Luckily, it didn't touch my backups.)

Did anyone else get a web driver update in the last few hours. I had one pop up out of the blue.

Yep. 3rd web driver since the supplemental update.

Hopefully the panic after the Software Update issue has been resolved, at the very least.

No, I checked off both options, I enabled both of them. The first one just downloads the latest drivers and the second one formats the drive for Windows, which you need to install Windows. It does not really matter which version you are using as long as it's 64 bit, so you can ignore it stating Windows 7 or 8. 10 Works just as well.

Alright, thanks! Got a DVD and have burned the ISO, so far. Gonna install when I get the chance.

[doublepost=1509471812][/doublepost]So which AMD GPU is the best OOTB replacement for my damned Titan Xp then ?

I see RX 580 mentioned a lot - can see various XFX GTS Core, Sapphire Pulse and Nitro+, Gigabyte Aorus, Asus Strix and MSI variants with 4GB or 8GB RAM - any preferences on any of these or much of a muchness ?

Anything better than RX 580 ? Not too worried by cost - more interested in stability and getting away from these infernal boot loops with nVidia cards.

Well, it depends upon which OS you're using. Aside from its Windows issues (which may not have anything to do with the card itself), this RX 580 is doing brilliantly well. I replaced my glitchy GTX 1060 with it. Even whilst the GTX 1060 did work properly, it performed far lesser in comparison. This RX 580 seems to be flying within OSX (and, it even performs much better in Windows than does the GTX 1060). My only gripe about it is that I can sometimes hear its fans spin up when I'm watching a video or doing anything else that's taxing enough. (Although, keep in-mind that I am running a QHD display.)

All I have to do is figure out this quirk, which may just entail my wiping the Bootcamp disk and installing Win10 cleanly. My machine exhibits no boot loops, mind you. It's just that the 580 seems to not want to show up until the GT 120 is in there with it.

BTW, if you get an RX 580, you have a choice as to which model you buy. You can pretty much get any major brand, except for XFX; this particular brand apparently has issues. Sapphire, MSI, Gigabyte, and ASUS all seem to work fine. The one which Apple specifically uses within their [beta] eGPU kits is the Sapphire PULSE RX 580 8GB. I'm assuming that a 4GB model is just fine; however, I wanted the full 8GB of RAM / the same model which Apple uses, and I was lucky enough to find a like-new 8GB model for the cost of a new 4GB model. It's nice having the extra VRAM.

Well, I tried doing the installation just now, but I received this error screen upon boot-up. I burned a legit ISO (straight from M$'s website) onto a DVD, with Disk Utility... so, I am wondering why this is occurring.

(BTW, none of the options work - they bring me back to this same screen. I get nowhere.)

EDIT: looks as though I simply burned the disc at a rate of speed which was too high to produce a stable installer DVD! I burned at a rate of 3x instead, and all is good. I am currently testing on an actual Windows PC, to see if everything goes well. If so, my Mac Pro will be ready for this DVD.

Windows 10 is all up and running, and my RX 580 is now working fine all by itself!! So excited to configure everything now.

A good rule of thumb is to burn ISO's and critical data at the lowest possible drive speed. I learned that the hard way back in the early 0's while burning games for my Xecuter modded OG Xbox.

Thanks! Typing from it right now, in fact. The only issue is that there is physically no option for system sleep - only hibernate and shutdown. Does a 4,1/5,1 owner have to install Windows 7 Bootcamp drivers or something? I believe that everything else is in order - Bootcamp control panel and all; alas, no sleep option.
