280X? Impossible. The HDMI is a V1.4 port, not 2.0.
If you need 4k 60Hz via HDMI, you will need a DP to HDMI ACTIVE convertor.

280X? Impossible. The HDMI is a V1.4 port, not 2.0.
If you need 4k 60Hz via HDMI, you will need a DP to HDMI ACTIVE convertor.
normally if your card subvendor website says it goes to 4K, your flashed card will go 4K with the same resolution too, i tested mine with 4K tv and monitor 3800x, all ok, but dont play games, so cant tell you the behavior in games
There is NO R9 280X has HDMI 2.0. So NO 4k 60Hz via HDMI on any R9 280X.
He was asking about 4K 60Hz, not just 4K. Please show us how you get 4K 60Hz on your 4K TV with the R9 280X onboard HDMI port.
No GCN 1.0 GPU supports HDMI 2.0. HD 7970/R9 280X are GCN1.0 GPUs and only support HDMI 1.4.
GCN 1.0 GPUs are almost 20 months older than the HDMI 2.0 spec, so no 4K 60 Hz via HDMI, only via active DP to HDMI adapters.
Maximum HDMI resolutions for a HD 7970/R9 280X GPU are:

If I don't care about the boot screen/efi stuff.... Will a R9 280x vapor edition work? I have a mac pro 5,1 and I can't seem to get any video. The card was working in my backup gaming rig so I know the card is good. I am using 8pin to 6 pin adapters. I have tried using both adapters and just a single adapter. On my gaming rig I would only use one power plug and it always worked fine. Basically it just doesn't allow me to use the secondary DVI connection (which is fine since I don't use two monitors and it uses less power this way). IE: one power cable is for one port/portion of the card and the other power adapter is for the other port/portion of the card.
Am I missing something?

I'm trying to understand your question, if you want to use a r9 280x on a macpro, no matter it's Mac efi or not, you need to connect both power cables, or it will not work properly, if your card is original one without flashed, you should have four video ports activated under Mac osx, and you can connect with 3 monitors simultane, but I don't play games, don't know if two dvi use more power? I doubt it !
Thanks. I have both power cables hooked up. Tried two different monitors, tried display port, hdmi and dvi... no dice. My ati 4770 that came with the machine works fine. The r9 280x works fine in multiple other machines.
I will try the boot rom 140 and see if it helps.

I have a Sapphire R9 280x VaporX OC that I am waiting on the cables for. It has 2 - 6 pin power connectors on the card, instead of an 8 pin and 6 pin like others have. Is this perhaps an older version? I picked it up on eBay cheap, and will use it in my Mac Pro 5,1. Was thinking of flashing the ROM, and it has a pushbutton switch for the two ROM positions. I want to run Mojave on it, so this card, if it will work, is a good one. I think I will try it first, and see if I need to flash it, I don't need the boot screen really as I have the ATI H5770 that came with the 5,1.
But, if I do decide to flash it, any recommendations as to the version file I will need? I have read Netkas, and here, but will be flashing with the Mac version of the program.

Lol, we'll that fixed the apple chime I never heard before, but now it won't boot into the OS. Keeps going in a loop asking me what language and then gives me utilities to reinstall, time machine restore, disk utility etc.
Good thing I have time machine. Doing a restore and then will try putting in the r9 280x after.

I had that happen before from a corrupted BootRom. Also, every time it asked me for a language selection, it added another language selection file to my nvram.
Rebuilding the firmware was the only way to fix it. I hope this isn't a similar situation for you. At least one successful boot is required to refresh the firmware. If you manage to get it booted, don't shut it down. Do a firmware dump, and binwalk your rom dump to make sure you're good there. If there seems to be a firmware problem, reach out to @tsialex for help.
Ok, restored and all looks good again... now you have me worried about rebooting. This is the wife's machine and she will be very upset with me if I Bork it. Lol.
I would assume if it rebooted fine once it should be good again.
No guts, no glory! Here comes the 2nd reboot.

That's why I said you should binwalk a rom dump just to make sure. You're probably okay, but it wouldn't hurt to check.
I have rebooted it a half a dozen times now and it's seems fine. I put the r9280x in the machine and I still do not get video. I decided to take my other machine use its power supply to plug in and power the video card using the same connectors that I knew worked in that machine and then I powered up the Mac and still no video. Don't think it's a power issue at this point. Put the video card back in my backup gaming box and it works fine. Put the original video card back in the mac and it's normal again
Shrug, guess I look into another card

try this: when start chime, press alt, choose your working system, when entre in the desktop, enter paramettre systeme - start up disk - choose your disk actuel, then restart mac to see if it shows again the reinstallation.
Recently my MSI 280x Gaming 3G starts going into what I can only describe as screen fits, but only when I try to run the BOINC client running Einstein@Home, which makes calls to the GPU for calculations. If I turn off the GPU, all is normal.
Wondering if it's something in 10.14.3 that's doing it, as things were just great in 10.14.2.
Hate to have to jump ship to a non-EFI card like the RX 580, but 280x seems to be hard to find for reasonable price on non-eBay sources.

having no ideal about your problem, but if you want to buy r9 280x, it was a model with great succes for the time, you will find a lot of sellers on your local "personnal trade" website in almost every country, ebay is more expensive than local website, but you will not be covered by guarantee when you buy from other website!
Looks like the issue was caused by the delta update of 10.14.3. It brought me to 10.14.3 build 18D42.
People are now reporting Apple fixed the combo updater, so I downloaded it, ran it, and I'm now at 18D43.
Deleting and re-installing BOINC got my project running again. Temps seemed a little high in the PCIe sensor so I revved up the fan just to make sure.
I got this MSI Gaming 3G 280x back in September of 2014, it may be time to take it out, give it a thorough cleaning, and re-apply the thermal compound...

Started getting screen fits again and decided to disassemble the MSI. Removed the cooler assembly and lo and behold- sloppy paste application, it was all over cooler die and covering mounted resistors.
Plus, the paste had four years or so to dry out/drop below spec.
Used Q-tips and 99% isopropyl alcohol pads, removed excess paste from area around chip and cooler.
Carefully applied brand new tube of Gelid Extreme paste, sculpted a nice thin, even square over the GPU, then closed up the unit making sure no paste was toothpasted out of the contact area.
Card now acts like nothing ever happened, all temps normal and I can saturate the GPU with the BOINC project without screen fits.
When I do get a new GPU like perhaps a 580 or Vega, gonna take it apart first and make sure the thermal paste is applied properly..

I simply apply liquid metal to all my GPU now. Super effective, never dry up, just need to make sure it won't short the circuit around (and the contact point is not aluminium).
