6800 XT - No Video Output (BIOS or OS) - Advice before RMA?

Hardware Hub Build a PC

Long story short, I’m trying to figure out if I just need to RMA this card, or if there’s something I’m missing or another check I can do.

Long story longer… I got a 6800 XT, but it has no video output (on BIOS or OS), but the old GTX 1060 it’s meant to replace does. Doesn’t matter the PCIE slot (I’ve swapped them and the 1060 works) nor the cable (DVI or HDMI) as both work on the 1060, and not on the 6800 XT. I’ve tried it in both slots alone and in tandem with the 1060, and it never has an output.

It is “seen” by the OS (though I’m running Fedora Silverblue).

Motherboard: ASUS TUF GAMING X570-PRO (updated BIOS 4802)
CPU: AMD Ryzen 7 5800X 8-Core Processor
OS: Fedora Linux 38.20230915.0 (Silverblue)

I’ve no idea how to make the driver actually run (I’ve removed Nvidia drivers and kernel parameter blacklists, but this is what is running.

$ glxinfo | grep -i device
    Device: NV136 (0x1c03)

My understanding is that the linux kernel has drivers built in (and I still have no idea why the BIOS never shows – that’s what makes me think RMA), but my understanding is that the below output seems to suggest I have drivers that should work.

$ lsmod | grep -i amdgpu

Posted on Fedora Forums here, but I’m mostly trying to figure out if I just need to RMA a 6800xt I just got to replace my GTX 1060.

I’m willing to believe I’m an idiot and have overlooked something basic, but I’ve also never had to RMA before, so want to ensure I’m not missing something obvious as I’d rather it work.

Any advice or guidance appreciated. Happy to post additional output if useful.

Adding more output from a live Fedora USB.

Still on the live USB. Seems as if there are no drivers loaded (even though my understanding is that they should be). It’s possible the Live USB is preferencing the nvidia card?

At any rate, I’ve bolded the part I’m understanding to be important below (from this thread).

More fun liveUSB output. This has error messages I can try to track down.

Further notes. I’m reading here that apparently one of the above error lines may show up if there is not a HDMI cable plugged into the GPU when booting in linux… so I’m going to reboot and try that (I think I have, but we’ll try again).

Did not matter. Same result and output. Ideas welcome.

If the GPU has no output in the bios, then linux has nothing to do with it. Aside from trying different ports, or changing your bios config(enable/disable rbar, switch pcie link speed), or maybe testing with a different power supply/different board, the card is a dead duck. RMA.
The GPU it’s self may work perfectly, and the display signal controller is dead. It could also be all four dead ports.

Thank you. This was my suspicion.

not much help from the manual… other than a white led will light up on the error panel and stay on if the gpu has an issue.

the board supports ryzen with graphics so make sure your set to peg-1 mode and the gpu is in slot 1.
unplug everything that isn’t the boot drive, pull all the ram bar 2 sticks making sure there in the correct slots for 2 stick config.
try and boot.

if you still get the white led then i would try the gpu in another build if i can to make sure.
then rma it if it fails there too.
regardless though it does sound like you got a DOA.

No idea if you’re still trying, but I had to reset my CMOS when I got a GTX 960. I had the same deal. No video output. Pulled the CMOS battery (and power cable), left it for a minute and then tried it again and it worked…
In my case I knew the GPU was fine because I’d tried it in another system when it didn’t work in mine.

Smells like this

Set the bios to CSM disabled and enable above 4g decoding and resizable bar

And make sure bios is up to date

If that doesn’t work try setting the slot to manually work at pci-e 3.0
