RTX 3090 Asus rog strix 24GB NOT SHOWING GPU

Hay frends

I have a big problem with one of my 5 rtx 3090 asus rog strix 24gb gpu s, i tryed many things from the internet, bios settings gen 1 and 4g decoding, i changed risers and also try to start my rig with the card on board. I try also to use hiveos because of the auto detecting gpu bu also then the card is not showing, im realy confiused i realy hope that the card is fine, i buy everything newly all the cards also new and dont used before. Im struggleing above 2 weeks on that so any solution will be tiped, also i try man windows solutions but no one worked like deleting display drivers and installing new or running several scans on cmd.

These are my datas:
Motherboard: asus z270-p
Ram: one 8gb ram stick
Power supply: 2000w
Cpu: interl i5 9th gen

Whoa - so you have five of these RTX3090 cards that cost around $AUS3500 each.
must be some rig setup you have!

and the other four cards are working fine?
if so, and it’s just this one card not being detected by the motherboard, I’d be assuming it’s dead on arrival and returning it.

Yeah the others work fine and i try it on 2 diffrent motherboards, how can it be dead ? I get it new and is there any way to repair it or is there a way that i can be 100% sure that its dead

[Bruce]

dead on arrival, while rare, does indeed happen, that’s one of the reasons they have warranty for.

if you brought 5 cards, 4 work and 1 doesn’t, then it’s not your setup (plus you have tried it in another mobo) and assuming you are connecting the dodgy one the same as the others, then yes, chances are excellent you have a bad egg.
