Rx vega 56 not recognized

[jojojo2810]

My specs are i5-4690k,Msi z97m Gaming,evga supernova g1 750w psu,16gb ram and i have a gtx 970 and a new Vega 56. I previously had another Vega but i returned it cuz i thought it was DOA. Well it tourns out that the new Vega I bought (while waiting for my old one) shows the same problem. The motherboard dosn't recognize it at all. I tried swaping the ports and everything. Now im running a gtx 970 next to it just to se if it works and the gtx 970 works. The radeon logo lights up but the power leds don't show anything. The one before did the same thing and when I pluged it into my firends pc one power led lighted up and nothing else. Any thoughts?

Stop buying AMD graphics cards?

But on a serious note, is everything properly connected and your GPU properly powered with the PCI-E cables? You need to make sure the cards is properly inserted and clicks. And do you get to Windows or just a black screen?

Well i bought it to mine and yes everything is properly connected and locked

Can you get into Windows with it? Or how do you know it's not recognized.
If you can get into Windows and you can run 970 and not this one, I know which is the problem for sure. You need to do a clean install of your drivers using DDU, and get the proper AMD drivers after reboot. Install them, reboot again. GPU recognized.

Well i get no signal from it so i have to connect it to the integrated gpu to get to windows and then i see that there are no display adapters found other that the Intel HD Graphics 4600. Also i can't instal the amd drivers cuz it says no AMD cards connected.

I'm not sure and I can't find anything online to say Vega has issues with non-UEFI installations of Windows. If someone with a Vega card can help it would be great. I've seen a similar case earlier but the person that posted knew for a fact, the type of card since he already changed the legacy compatibility. Vega doesn't seem to mind about that. You could still try to reset the bios by taking out the battery. I'd back up my stuff before going further with tests to make the card work.

I’m having the same issue with 2 of my Vegas. The mobo recognizes the other Vegas but the logo lights up on the two that don’t work but the power indicator lights don’t turn on and the mobo doesn’t recognize them. Not sure what the issue is yet.

Is there any development on this issue?
I have the same problem, only the logo shines and does not recognize it.
