if the fans are not spinning and the card is not recognized then its dead.

The cards are only about 2 weeks old.
I live in Kuwait and this is the first time I have purchased from the retailer where I got the cards from.
Some retailers do play games and refuse to exchange merchandise after box has been opened.
I will try to take it there tomorrow and request an exchange, otherwise.. I'll send it directly to AMD.

If the card is dead, any chance they will know I flashed the BIOS?
Does BIOS flashing void the warranty?

try unplugging the ones that work and isolate the one that isnt working to make 100 percent sure.

I did isolate the card, no risers being used. It doesn't work when connecting to the motherboard.

I would just use that card, unplug all others, disable igpu and than boot on a Linux distro. If it works, it is Windows if not time to rma that card.

I doubt it's windows, otherwise the other cards wouldn't work.
I will however try booting into UBUNTU and see what happens.

I hope u used the modded bios with the same bios number what you originally had on your card
If you using modded bios with different bios version number , you have a chance to kill all your gpu's !!!

I have just checked one of the good cards, noted the current modded bios number, re flashed the original bios.. and the numbers match. So yes, the BIOS version is the same according to GPU-Z

Do you have automatic updates enabled on your computer ?
check if you get some unwanted updates .
use DDU, remove the drivers
plug in the non working card let see what happening

Interesting, I got an update within the past 48 hours.. Although I'm surprised only 1/3 cards is not working, who knows.. it might be something related. Will get back to you on this! Thanks!

So you have problem to boot into windows ? can you see the bios post ? can you boot into your bios with the bad card and monitor connected to the "bad" card ?

No signal at all starting up the computer while connected to the bad card. Screen doesn't see a signal when connected to the bad card. I can boot into windows fine with the motherboard's built in display adapter and with the other two cards.

Two more pieces of info:

When checking things with Sapphire Trixx, both cards go back to 0 Clock, 0 Mem..
It's like something is setting them to turn off..

Also, I've just discovered that I have 1 bad riser.. it is probably the riser that caused this mess.
I tried connected a good card to it, and the card doesn't work..
Tried a different riser, good card works fine.

I now have a bad card and a bad riser!

Question....

If the card is indeed DEAD.. Electrically or otherwise..
Will AMD ship me another card? (I will take it to the shop tomorrow and see what they say)
