    This thread is about compatibility of Polaris & Vega graphics cards with the Mac Pro. In general Sapphire Pulse GPUs have the best compatibility. Please help others in the community by sharing your experiences with these cards. Also be aware that the behaviors of these cards is different in a hackintosh and this thread is limited to the genuine Mac Pro only.

    Apple supports and recommends Polaris and Vega graphics cards for the Mac Pro 5,1 in macOS Mojave. They support all Metal feature sets in Mojave, including family 2 version 1. However, none of these cards support the boot screen on a Mac, FileVault, FreeSync in MacOS, or the ability to apply firmware updates. But they do support Recovery Mode. For Boot Camp without a boot screen see this thread: https://forums.macrumors.com/threads/how-to-boot-camp-without-a-boot-screen.2114788/

    GPUs with the following Polaris GPU device IDs are supported in macOS 10.13.4 through 10.14 beta:

    The following Vega graphics cards are properly identified in About This Mac and System Information:
    -Radeon Pro WX 9100
    -Radeon Vega Frontier Edition
    -Radeon RX Vega 64
    -Radeon RX Vega 56

    Current issues for PC graphics cards:

    -Some of these cards have trouble displaying over DisplayPort 1.2 or later. Solutions: Set your monitor to DisplayPort 1.1 mode or use a DisplayPort to HDMI adapter.

    -The power requirements for some of these cards exceed cMP specs. Note that a Vega card takes very little power from the PCIe slot and instead takes nearly all power from the boost cables, so to be safe go by the boost connectors (6-pin = 75W & 8 pin = 150W). For example, the Sapphire Pulse RX Vega 56 has a TDP of 180W which is actually 45W less than the Pulse RX 580, but since it has two 8-pin boost connectors it may try to pull more power over them than the cMP can handle. The solutions for that are Pixlas Mod or separate power supply. However, there are a few Vega cards that have a 8-pin + 6-pin boost connectors. It may be possible to use a dual 6-pin to single 8-pin cable and use power from the optical bays (SATA) for the 6-pin connector. That solution may not be as safe as Pixlas mod, but some people are successfully using that method to power other cards with that connector combo. 8 + 6 pin Vega cards include Radeon Pro WX 8200, Radeon Pro WX 9100, PowerColor Red Dragon RX Vega 56, and PowerColor RX Vega 56 Nano Edition.

    -Some Vega graphics cards have high idle fan speed when installed inside a cMP (but not when installed in an eGPU enclosure). See Vega High Fan Speed Issue section below for more information.

    -eGPU connected over TB2 to Mac Pro 6,1 does not work. Solution: Patch available here.

    -These cards have a link speed of 2.5 GT/s (PCIe 1.1) rather than 5.0 GT/s (PCIe 2.0) when installed in cMP's slot 1 or 2. However, this does not reduce performance in realistic scenarios.
    Update: These cards have 5.0 GT/s (PCIe 2.0) link speed with 5,1 firmware 138.0.0.0.0 included with Mojave beta build 18A365a. Note that some cards still incorrectly show 8.0 GT/s in System Information.

    Vega High Fan Speed Issue

    There is an issue where the fan(s) on some Vega cards spin constantly at high speed. Below are lists of cards that have been tested by myself and/or by others. You are encouraged to test additional cards. The fans on cards in the "Issue not present" list still run at idle, but at low speed. As of Mojave beta build 18A353d the fans on those cards now behave normally at idle (zero RPM), but a new issue has been introduced (see the second fan issue section below.) Note that this issue only applies to cards installed internally in a cMP. Note that the reference RX Vega 56 & 64 cards are available from most of the AMD partners and are the original blower design with AMD PCB. Reference cards all have the exact same AMD supplied BIOS.

    Issue present:
    -Reference RX Vega 56 & 64
    -Radeon Vega Frontier Edition
    -Radeon Pro WX 9100
    -XFX Double Edition RX Vega 56 & 64
    -Gigabyte RX Vega 56 & 64 Gaming OC
    -ASUS ROG Strix RX Vega 56 & 64
    -MSI RX Vega 56 & 64 Air Boost

    Issue not present:
    -Sapphire Pulse RX Vega 56 (model 11276-02)
    -PowerColor Red Dragon RX Vega 56
    -PowerColor Red Devil RX Vega 56 Note (!): The Red Devil card is too long for the cMP unless the PCIe case fan is removed (not recommended).
    -Sapphire Nitro+ RX Vega 56 (model 11276-01) Note (!): The Nitro+ card is too long for the cMP unless the PCIe case fan is removed (not recommended).
    -Sapphire Nitro+ RX Vega 64 (model 11275-03) Note (!): The Nitro+ card is too long for the cMP unless the PCIe case fan is removed (not recommended).

    Unknown/untested:
    -Radeon Pro WX 8200
    -PowerColor Red Devil RX Vega 64 (Probably doesn't have fan issue since 56 version doesn't.)
    -PowerColor RX Vega 56 Nano Edition
    -ASUS AREZ Strix RX Vega 64
    -PowerColor Red Dragon RX Vega 64 (Probably doesn't have fan issue since 56 version doesn't.)
    -Dataland X-Serial RX Vega 56 Note: Appears to be the same card as the PowerColor Red Dragon RX Vega 56 so probably does not have fan issue.

    Solution for RX Vega 56 and 64 that have this issue: Use BIOS for non-affected card such as Sapphire Pulse or Nitro+, but only if your card model is known to readily accept a different BIOS. See BIOS compatibility section below. Note that an RX Vega BIOS cannot be flashed to a Frontier Edition, WX 8200, or WX 9100.

    These combinations have been tested and appear to be working normally:
    -Reference RX Vega 56 with Sapphire Nitro+ RX Vega 56 secondary BIOS

    Alternate solution (for all Vega cards): Modify kext (driver) to change fan speed. Instructions linked here. Note: This solution is not recommended because the Kext Signing and Filesystem Protections of System Integrity Protection (SIP) must be disabled in order for the modified driver to load which may leave your system vulnerable. It must also be performed each time there is a macOS software update.

    Second fan issue

    As of Mojave beta build 18A353d the cards that don't have the high speed fan issue listed above have a new issue where the fans spin up high under load as expected, but then fail to spin down. The fix for this is playing an H.265 (HEVC) video until the fans spin down.

    RX Vega BIOS Compatibility

    There are 2 main variants of the RX Vega PCB, standard (full size) and nano. To be safe I recommend only flashing a nano card with a nano BIOS. This is because the VRMs are smaller and must not exceed 105 °C. Standard PCB bioses often have a VRM target temp of 115 °C or more. The standard card can be safely flashed with either another standard BIOS or a nano BIOS.

    Nano PCB:
    -Sapphire Pulse RX Vega 56 & 64
    -PowerColor Red Dragon RX Vega 56 & 64
    -XFX Double Edition RX Vega 56 & 64
    -PowerColor RX Vega 56 Nano Edition
    -Dataland X-Serial RX Vega 56

    Standard (full size) PCB:
    -Reference RX Vega 56 & 64
    -Gigabyte RX Vega 56 & 64 Gaming OC
    -ASUS ROG Strix RX Vega 56 & 64
    -ASUS AREZ Strix RX Vega 64
    -MSI RX Vega 56 & 64 Air Boost
    -PowerColor Red Devil RX Vega 56 & 64
    -Sapphire Nitro+ RX Vega 56 & 64

    Warning (!): Some cards do not accept the BIOS from another card. The following cards do not readily accept another BIOS and the failed flash may not be recoverable:
    -XFX Double Edition RX Vega 56 & 64 (unknown if other version of same card can be flashed to it)
    -PowerColor Red Dragon RX Vega 56 & 64 (unknown if other version of same card can be flashed to it)
    -MSI Air Boost RX Vega 56 & 64 (other version of the same card can be flashed to it)

    The following cards are known to readily accept a different BIOS:
    -Reference RX Vega 56 & 64
    -Sapphire Pulse RX Vega 56

    To flash a different BIOS to your card it must be done using Command Prompt in Windows ran as an Administrator. The following commands will force flash a different BIOS:
    AtiFlash.exe -f -p 0 path-to-new-vbios.rom (with single card installed)
    Note: It appears atiflash starts the slot position count at the top. For example, if you had 2 cards installed with one in slot 3 that would be 0 and one installed in slot 1 that would be 1. So then if you wanted to flash the card in slot 1 with 2 cards installed you would type, "AtiFlash.exe -f -p 1 path-to-new-vbios.rom". If you accidentally flashed the wrong card then quickly flash it again with the correct bios before restarting the computer.

    If you put the new BIOS in the same directory then you just need to type the name of the new BIOS file (replace "path-to-new-vbios.rom" with the name of your rom). A new BIOS can be found online such as TechPowerUp’s VGA Bios Collection. Note that some BIOSes such as for the Pulse and Nitro+ are found under unverified uploads (the verified Nitro+ on their website is for the limited edition card and should not be used on a card that does not have 3 power connectors). Note that using a different BIOS on your card may void the manufacturer’s warranty (if you weren’t able to restore the original BIOS). Always backup your original BIOS using a program like GPU-Z.

    Note that it doesn’t seem to make any difference if a card has Samsung or Hynix memory for a Vega BIOS. The BIOS will autodetect the memory type.

    Some people feel an open-air cooled card BIOS should not be used on a blower cooled card due to concerns about temperature. It is up to you to monitor temperatures. The BIOSs have the same target temps for both types of cards so this concern may be unwarranted.

    If you flashed a BIOS to your card that didn’t work then shut down the computer and flip the BIOS switch on the card. Then start Windows and while the computer is still running flip the BIOS switch back. Then you can proceed to flash over the failed BIOS.

    "No fan issue" BIOS list:
    -Sapphire Pulse RX Vega 56 (nano PCB): 113-376XL-UO1 (primary), 113-376XL-U43 (secondary), 2nd version: 113-376XL-UO2 (primary), 113-376XL-U44 (secondary)
    -Sapphire Nitro+ RX Vega 56 (standard PCB): 113-D0500310-O01 (primary), 113-D0500310-S01 (secondary), 2nd version: 113-D0500310-O02 (primary)
    -Sapphire Nitro+ RX Vega 64 (standard PCB): 113-D0500110-O01 (primary), 113-D0500110-S01 (secondary)
    -PowerColor Red Dragon RX Vega 56 (nano PCB): J8320JAD.ROM (primary)
    -PowerColor Red Devil RX Vega 56 (standard PCB): J8B27OAL.HLD (primary)

    Andrew’s cMP Graphics Card Recommendations

    Here are my recommendations for cards that have a good balance of performance & power consumption and have good compatibility.

    Basic cards:

    MSI RX 560 AERO ITX
    Pros: Recommended for Mojave by Apple for Mac Pro 5,1, low power consumption (60W), good for general purpose computing
    Cons: Not good for demanding 3D workloads or gaming
    Other considerations: 2 slot-width, requires no power cable

    Sapphire Pulse RX 560
    Pros: Low power consumption (90W), good for general purpose computing
    Cons: Not good for demanding 3D workloads or gaming
    Other considerations: 2 slot-width, single 6-pin power connector
    LuxMark luxball score (Mojave): ~5500

    Radeon Pro WX 4100
    Pros: Low power consumption (50W), good for 2D workloads (CAD)
    Cons: Not good for 3D workloads or gaming
    Other considerations: single slot width, requires no power cable

    Mid-level cards:

    Sapphire Pulse RX 580
    Pros: Recommended for Mojave by Apple for Mac Pro 5,1
    Cons: Less powerful than Vega except in certain apps, relatively poor efficiency for performance (225W)
    Other considerations: 2 slot width, single 8-pin power connector requires dual 6-pin to 8-pin cable
    LuxMark luxball score (Mojave): ~15,000

    High-end cards:

    Sapphire Pulse RX Vega 56
    Pros: Powerful, very efficient for Vega (180W), quiet, low temperatures, readily accepts BIOS flashes
    Cons: 2.5 slot width blocks second PCIe slot
    Other considerations: Dual 8-pin power connectors require Pixlas mod or separate PS.
    LuxMark luxball score (Mojave): ~26,500

    PowerColor Red Dragon RX Vega 56 (also sold as Dataland X-Serial RX Vega 56)
    Pros: Powerful, very efficient for Vega (180W), quiet, low temperatures, 2 slot width
    Cons: Users on other forums have reported that a different BIOS cannot be flashed to this card and the failed flash cannot be recovered.
    Other considerations: 8-pin + 6-pin power connectors require Pixlas mod or separate PS. Alternative solution may be a dual 6-pin to 8-pin cable plus 2x SATA (from the optical bays) to 6-pin.

    OpenGL issues appear to be resolved with RX Vega 56 GPU. Google Chrome now works well with hardware acceleration and WebGL enabled.

    Preview no longer crashes when attempting to crop a photo.

    The LuxMark v3.1 luxball score increased by 2531, from 20251 (on 10.13.1 beta build 17B25c) to 22782.

    Also, on previous builds sometimes a window would flash solid red when minimized or the section of the screen would be solid red where a crashed window was. So far that no longer occurs.

    If they don't fix the fan speed issue I may have to switch to the liquid cooled 64. Something to keep in mind if you haven't upgraded yet. Everything else so far appears to be perfect.

    may I enquire if you have tried a PRAM and SMC reset to see if that stops the fans from spinning all the time?

    I haven't tried that yet because that will reset SIP and I need it disabled to run Boot Champ. I'll see if I can boot into Recovery mode. On previous builds it would boot into it but only show a grey screen.
    --- Post Merged, Nov 2, 2017 ---
    Recovery mode works now. Resetting SMC and PRAM did not fix the fan speed issue.

    thanks for the update. What brand of card are you using? I am looking to buy a Sapphire Vega 54 and hope the fans get fixed in the next update.

    Little chance for this... In 10.13.1, at idle, reference vega frequency already throttle because of the heat.
    10.13.2 first beta brings better heat handling, and the card is far cooler now at idle: it allows higher frequencies (I got 15% geekbench compute score increase), at the detriment of fan speed and noise.

    Admittedly, this isn't very scientific, but I've had situations where my fans (RX480) kept going after startup. I learned that if I started a benchmark like 'Heaven', that in turn would trigger 'full fan mode' after a while. But once I exited Heaven and the card cooled down, the fans would go quiet as well.

    Can't say when it began or if it was fixed permanently, but if I hear the fans after reboot, I start Heaven and let it run for a bit. Then I exit and the fans go quiet. That "trick" has never failed me.

    Might be worth a shot.

    The fan should not be running that fast at idle. A geekbench benchmark does not run at idle. It puts a load on the card and in that scenario the fan should run faster.

    Thanks for the tip. I tried it. It didn't work.

    Here's another issue. The Mac does not wake from sleep and the graphics card fan continues to run at full speed when it's sleeping.
    --- Post Merged, Nov 5, 2017 ---
    I've reported these issues to Apple using Feedback Assistant.

    On my MacPro with a RX-480 and a 5770 wake from sleep is definitely an issue. Started with 10.13.2 beta 2.

    Interesting, haven't had any issues with other VEGA 56, but haven't tried the Sapphire as well. Will buy one and report

    Are you using 10.13.2 beta? Since these are AMD reference cards they should all have the exact same vendor ID, device ID, subsystem vendor ID, and subsystem ID so MacOS should be treating them the same. I know those all match between the XFX and Sapphire cards. And since they are the same cards you don't have to buy another one. You should be able to flash the Sapphire BIOS onto one of your existing cards.

    Vendor ID: 0x1002

    Device ID: 0x687f

    Subsystem Vendor ID: 0x1002

    Subsystem ID: 0x6b76

    Revision ID: 0x00c3

    This is the BIOS on my card. I verified that with the GPU-Z app and it said this is it.

    It looks like you wouldn't actually have to flash the BIOS because according to Techpowerup, they have the exact same BIOS. Version 016.001.001.000.008766. Therefore, no difference at all between these cards.

    Same Bios: AMD RX Vega 56, Gigabyte RX Vega 56, MSI RX Vega 56, Powercolor RX Vega 56, XFX RX Vega 56

    There is another BIOS, but I've just verified that is the secondary BIOS. Version 016.001.001.000.008767: https://www.techpowerup.com/vgabios/194756/sapphire-rxvega56-8176-170730-1.

    The fan and sleep issues were not fixed in the 3rd beta (17C76a).

    It's hard to believe this will stay broken. For the iMac Pro... maybe they have a custom power controller firmware or something else custom.

    But for eGPUs... that would be using stock PCIe cards. So I hope we get fan and sleep fixes because Vega as a PCIe option looks pretty nice.

    Even I have no plan to go Vega at this moment. I still wish Apple can fix it to leave us more practically usable GPU option.

    However, the iMac Pro will not coming with the Vega chip at standard setting with the reference cooler. There is no need for the driver to handle that.

    And Apple officially only support the Sapphire PULSE RX580 8GB as the eGPU. I don’t think they really care if Vega can’t work properly as an eGPU.

    There have been a lot of hints out there for Apple and partners that Vega will be supported as an eGPU.

    RX580 is just the hardware that was out at the time of the beta eGPU program. It won't be the end of the supported hardware.

    It's even likely post-beta Apple will roll out official support for third party eGPU drivers.

    I am sure lots of eGPU work, just like my 1080Ti never ever officially supported by Apple. But it works flawlessly in my cMP now.

    However, it work doesn’t mean that’s supported. As long as it’s not officially supported by Apple, anything can happen.
