The model of Sapphire Radeon RX580 that I bought, identified by part# 100411P8GOCL, ships with with a single-link DVI port. Most other revisions ship with a dual-link DVI port. It was also until recently cheaper than other RX580s for this reason why I bought it (typing on it right this second.) You need dual-link DVI to support 4K output.
I only have older DVI/VGA only monitors available to me at the moment, don't have access to any newer monitors that have HDMI ports which would let me connect at 4K resolution. I've modified my post to reflect this and deflect confusion.
tl;dr: I'm cheap as sh*t and bought an RX580 that won't drive the monitors I have available to me at higher res.
Right on the box it is identified as a Sapphire Pulse RX580, but it says "DVI-D" not "DVI-DL."
Only paid $219 for it, got it before all the prices got hiked.
SKU is 11265-05-20G.
So you're saying with your bolding what I've been saying all along, since I only have access to DVI / VGA monitors I'm not going to get 4K output even on those that support DL-DVI.
So 100411P8GOCL is the same as 11265-05-20G, which specs state:
Displays Maximum 5 Outputs
Output 1 x DVI-D
2 x HDMI
2 x DisplayPort 1.4
5120×2880 (60Hz) Pixel DisplayPort Resolution
2560x1600 (60Hz) Pixel Dual Link DVI Resolution
4096×2160(60 Hz) HDMI Resolution

I did a year ago for my 2009 cMP and am happy that I did. Even happier after I applied the AMD Hardware hack. Note that I have not yet gone the route of Open Core, which is mentioned at the outset of this thread. It is promising, but there are still unknowns.I am going to buy the

There's a surge of them on Amazon lately after the need to use with RX 580.
This is the Sapphire Pulse RX 580 8GB GPU that is approved. I've purchased this same GPU and it's identified as

Believe the older 30" ACD uses Dual Link DVI only (been awhile since I've used). These are active adapters. Do not believe the passive adapters have resolution required. Some may need mDP>DP adapters (above).

If you're scared of the CPU swap/upgrade and interested, dual 3.46GHz trays are available for purchase. It's much more expensive, but another option. If you do this just MAKE SURE you buy an authentic 5,1 tray and not a 4,1>5,1 tray. They physically look the same but are different parts.

Hey @bsbeamer, having some display issues that I'm hoping you or anyone else on this forum can help me out with. I followed your post (and links) and upgraded to the Sapphire RX 580 on my 2012 Mac Pro (currently on High Sierra). When I connect to my Dell U3011, I only have a max resolution of 1920x1080. I'm using a cable from the DP Out to DVI In on the monitor. When I try using a DP to DP cable, I have no signal. Do I need an adapter of some sort or special cable? I figured a DP to DP cable would just be plug n play? Thanks in advance for your patience and input~
@drose1979 As stated above, make sure you're using an ACTIVE adapter.
Thanks @MIKX, I ordered a similar active adaptor that is coming tomorrow. Fingers crossed**This works for me with an MSI Armor RX 580 8gb but I so not have a 4k monitor.
