Wow, this is the most detailed post about GPU support for Hackintosh. Thumbs up for you.

The only brand of GPUs to avoid with Vegas are XFX and Sapphire. Reason being is VBIOS communication issues which can't be easily solved with a reference BIOS due to how Vega's powerplay table interacts between the OS and GPU.
On Apple's support page they list these Vega cards as compatible in an eGPU enclosure. Both Sapphire and XFX. So if Apple has tested these in an eGPU and they work via TH3 why not installed internally in a PCIe slot in a CustoMac ? What is different when connecting externally that gets around the VBIOS communication issues ?

Nice post there have been a lot of changes in Mojave.

XFX R7-R9, and 7xxx cards have incompatible vbios.

XFX RX 460-560 models have the vbios issue as well.

There are reports of some users not being able to use XFX RX 570-580 models but it could be user error. I have 2 XFX RX 480s that have been running fine since the Sierra beta software and work great in Mojave beta. And many other users have XFX Polaris 10 cards working well.
XFX RX 590 Fat Boy is incompatible the vbios issue. So in general one should check to see if their XFX model is supported before buying.

Reference cards don’t have the fan issues whereas the multifan models sometimes have the fan issue (mostly in the Vega cards).

Sapphire is the go to Apple vendor. But there are reports of a few models having issues (RX 590). In general the Pulse models are compatible.

Well connecting externally isn't what changes as 2010-2012 MacPros don't have this issue either, it seems to specifically come down to how Hackintoshes use an emulated EFI vs a native one like in real Macs. This means that since we're emulating, we can get odd issues with translating from the hardware/firmware to the OS itself and this is the same reason why WhateverGreen requires a UEFI compatible graphics card to properly work

I can tell you that 100% would get crashes on my hack with the Vega card if I do not reboot every few days. Right now the max days uptime without reboot is 6 days and as the Op describes it is a disconnect. However, that same card in a EGPU on a MacMini TB3 does not have the problem. The card is a XFX Vega 64 Reference card also tried a MSI Vega 56 Reference card. Both card needed fan help VGTab in the hack, in the EGPU they do their thing just fine.

So by this standard someone with a Hack and TB3 with EGPU would experience the same issues because of the Emulated SM?

Theoretically yes, but since we're now routing the PCIE lanes through the chipset it instead of the CPU like on a desktop you can encounter either better stability or worse. Hackintoshes are on a case by case basis for these kinds of things and so it's hard to tell what would happen
