Asus Dual RX 580 8GB in Mac Pro 3,1 (2008) in 2020

Installation of an RX 580 in a Mac Pro 3,1 from 2008 is it worth it??
Did it work??

Well yes sort of!!
The Mac Pro 3,1 was from the $100 Tech haul https://youtu.be/_h1UGYwTTlg

Dual 2.8 Ghz Quad Core Xeon processors had the HD 5770 installed, ended up putting a 250GB SSD in bay 1 and 2 3tb HDD's in bays 3 and 4 in a software raid one for storage.

Wanted the RX 580 Metal support and the graphics compute power for rendering and exporting videos. Well for better performance may have to wait for my unicorn the Mac Pro 5,1 Dual processor. I will find it!!!

MAYBE!!


macOS Mojave patcher from @DosDude1 http://dosdude1.com/mojave/

Well the install did not go exactly as planned.
The Mac Pro 3,1 dose not have the SSE4.2 instruction set so the drivers for the RX 580 will not install properly. High Sierra appeared to be working and showed the card properly but there was no video acceleration. @DosDude1 to the rescue again. Installing Mojave with his patcher tool.. Link in the description Got the RX 580 working. Although not the best seems to be running in slow-mo in in OS X and just ok in Windows 10.
