MP 1,1-5,1 RX 580 on 2012 MacPro 5,1

[danallen]

Looking at RX 580 Sapphire Pulse graphics cards for 2012 MacPro 5,1. Everything I read says this will work great, especially if am ok running this without the mac boot screen.

There is one detail I am wondering about. I see various pci versions on these cards. This macpro has pci 2.0 slots. Is it ok to run GPU with pci 3.0 connection? I read something pci backward compatiblity, so I think it will be ok.

Any information you can provide will be much appreciated.

Yes. I used one a few years ago, and it worked perfectly!

They work fine, just make sure you get the right power cable to run them.

If the Sapphire Pulse RX580 8GB is a bit hard to find, you can also use a Sapphire RX6600XT 8GB and flash that (using a PC) so that it is compatible with the 5,1 Mac Pro. You will need MacOS Monterey however.

Bootscreen is no issue anymore, thanks to EnableGop:

Thank you for responding. Just to clarify, so I can be certain, was your RX 580 flashed with whatever it is tha causes the boot screen to appear? I am trying to make certain that R 580 Sapphire Pulse without the Mac flash will run my 2012 MacPro 5,1

Seems like there a many RX 580 Sapphire Pulses available on ebay.

I've got the Sapphire in my 4.1 Mac Pro and it works great.

Love mine. But as was mentioned above make sure you get the right power cable.

A few years ago I sold my new RX 580 Pulse ... and then realised I needed one afterall. So I bought one again - and it cost me more! A fair bit more!! They are cheap as now though ... I should have waited ... except that I did need one.

They were popular for bitcoin work, and the rule back then was avoid an ex bitcoin one. Good luck.
