Correct. This does NOT provide a boot screen.
You can buy EFI flashed cards on eBay or from MacVidCards
And I assume there isn't any post explaining how to do it yourself right? Again thanks for clarifying this, it helps to know.

Correct, there currently is no DIY method of doing so.And I assume there isn't any post explaining how to do it yourself right? Again thanks for clarifying this, it helps to know.
Being dumb here, but I'm helping out someone here with upgrading his 5,1 Mac Pro. From my understanding, this still won't allow for the GPU to show the boot screen at startup? Really need to know since he depends on it. Thanks!
Why he need boot screen?
I personally don't see the need for it, since most things can be done blindly, or one could just simply swap the GPUs, but he just doesn't want that hassle lol.
Are the hints discussed on this thread valid only for Sapphire-branded cards? I ask because I have a MSI RX 580 Gaming X 8G (https://www.msi.com/Graphics-card/radeon-rx-580-gaming-x-8g/specification) that I would love to tune by reducing the voltage (to make it cooler) and changing the fan profile. However I'm on a hackintosh, not on a real Mac.
Nope, that model has only one bios.Isn't there a bios switch on the card? I've got one on my Sapphire, click and done.
No need to do this anymore. Newer OS can ident the GPU correctly natively.hi would this work with the SAPPHIRE NITRO+ RX 590 GOLD EDITION?
You are right, I just tried it. I guess i'll use this in my mac pro now. thank youNo need to do this anymore. Newer OS can ident the GPU correctly natively.
Which OS? Catalina?No need to do this anymore. Newer OS can ident the GPU correctly natively.
From memory, HS, anyway, that's for RX580, not HD7950.Which OS? Catalina?
Ok so for the 580, one should be able to take a PC version, install into a Mac running HS or Catalina, and get a boot screen without having to flash the card's bios?From memory, HS, anyway, that's for RX580, not HD7950.

Understood now. Thanks for clarifying.Not on a 5.1 or prior, no. The OS detects the card and uses it properly; The pre-boot environment still runs UGA not GOP
You can, but the question become why.i am running Mojave is this possible also ?
OK you are right when i get the chance i will install open core .You can, but the question become why.
This whole thread is basically depreciated.
We prefer NOT to flash the RX580 nowadays, but use OpenCore to inject whatever we want.
By using OpenCore, we can get boot screen, HWAccel, and Orinoco framebuffer without flashing the card. So, there is no point to flash the RX580 anymore.
Just with WEG or are using any settings to get those? If you don't mind could please share your config.plist with me?We prefer NOT to flash the RX580 nowadays, but use OpenCore to inject whatever we want.

It is actually DELL OEM RX-580 which shares the hardware of the reference RX-480. I have 4 ports: 3DP and 1 HDMI. One of the DP will not work with this setup.is your RX 580 Sapphire or a different brand?
I am looking for a second-hand Sapphire Pulse but there is always the Nitro version. are these the settings you send works with also Sapphire Nitro?It is actually DELL OEM RX-580 which shares the hardware of the reference RX-480.
