Question I have a brand new GTX 3090 that was just sent to me by nvidia but it doesn't seem to be working, the previous one that I sent back experienced the sa

[film_guy01]

A friend asked me to build him a crypto rig. I did. He paid for all the parts. He got a GTX 3090. I set it up quickly and easily (I've built 6 or 7 computers before but this was my first crypto rig). The 3090 worked fine for maybe a month. Then it just stopped. It wasn't recognized when I plugged it into the PCI-E GPU Riser and it wasn't recognized when I plugged it directly into the PCIe slot either. Won't power a monitor either. It worked on both previously.

I figured the card must have gotten fried or something, so I got an RMA and sent it back. I just got the new one, and it exhibits the same problems.

I know that the PCIe slot it working fine because I also have a RTX 3060 that works perfectly when I plug it in.

I was wondering if perhaps it's some kind of power issue, but as it worked before I know my power supply CAN run it, and also all the GPU rainbow lights come on when I turn on the computer (for whatever that's worth). Also, if I take out the 3090 and drop in the 3060 everything works fine and exactly as expected.

Any thoughts on what the problem might be?

Thanks!

Have you tried the 3090 in another rig?

Also, how old is the PSU?

Agreed try in another system.

I haven't tried it in another rig, unfortunately, I don't have another rig to try it in.
But since it came directly from the manufacturer, unopened, and it exhibits the same problems as the last one, it seems like it's probably not a GPU problem. But I do wish I had another rig to test it in.

The PSU was one I had sitting around. So...not too new. Maybe 4 or 5 years old? But it DID work with a 3090 at one point. And it will run the 3060 any time.

If the PSU was providing inadequate power, it would perform the same with two GPUs. PSUs can, and do, break down over time, including providing less power. This seems a possible PSU issue.

Was this rig running 24/7 before the GPU problems occurred?

It was running 24/7 with the 3090 for about two weeks before it abruptly stopped. I suspected it might be a PSU issue to I ordered a new one. Should arrive tomorrow. Fingers crossed.
I'll let you know if that solves anything.

Thanks for your help!

🤞🤞🤞 Good luck. Looking forward to your update.

BTW, does this rig have more than a single GPU installed at a time?

It has in the past, but when I've been trying to get the 3090 up and running I've disconnected the other GPUs for the sake of simplicity and streamlining the troubleshooting.

 

[COLGeek]

Sounds like a failed PSU (previously overloaded and now unable to handle the high demands of the 3090).

Ok. So, update. Brand new power supply arrived today. HydroG 850W. I only ever plugged the 3090 into the motherboard since I've gotten this new power supply. Same deal as before. It won't even work with a monitor plugged in via HDMI. The rainbow lights come on, the fans spin for 10 seconds or so, and then spin down (although perhaps this is normal. I don't know. Maybe the fans power down if it isn't under heavy load).

I'm pretty much out of ideas at this point.

Any thoughts?

Did you use the new cables that came with the new PSU, or did you recycle the old ones ?

The old cables won't even fit the new PSU. I got an entirely new, better PSU than I had before. I used the cables that came with it.

I'm wondering how this ever worked, given the cpu and motherboard are not compatible.
The H110 chipset only supports 6th and 7th gen cpus. The 9100f is 9th gen and requires a 300 series chipset.

Sorry. I listed the wrong CPU. I edited my OP to correct that. The CPU I have is Intel 3.70 GHz Core i3-6100 3M Cache Processor (BX80662I36100)

Man. You sure know your chipsets.

 

[film_guy01]

Any other ideas? I don't even know where to go from here. I feel like I've tested every component separately and they all seem to be working fine.

-3090 doesn't work in the riser, 3060 works in the riser
-3090 doesn't work directly in mobo, 3060 does
-Power supply replaced, no old cables were reused, nothing changed
-3090 replaced for another 3090, but new 3090 does the first 2 things over again

Did I get that right?

That's exactly right.
Also a 3090 did work once for several weeks when I first installed it.

Does the 3090 use a 12pin adapter that was included in the packaging?

If the above is no:
The motherboard may be the REASON the 3090 isn't picked up, but it's not the actual culprit.
I suspect the riser is the actual culprit. Looking up reviews of these Ubit devices, QC is all over the place. Worst cases, people lost motherboards, gpus - and the risers themselves - to:
Capacitors blowing up, catching fire, or leaking.
USB shorts.
Pulling more current than they're supposed to, aka, an overload. That would explain the capacitors...

There were no adapters in the packaging. Perhaps this was because it was a replacement? There wasn't anything in the packaging except for the GPU itself. Not even instructions or stickers.

I'm not certain I understand what you're saying. So you think maybe the riser caused some kind of motherboard damage that is now keeping the 3090 from functioning properly?

Well, did the previous 3090 have such an adapter?
There was a slightly older thread - HERE - where the OP's 3090Ti wouldn't run. Turns out the original adapter that came with it turned sour, and replacing it got the gpu up and running again.

I'm not certain I understand what you're saying. So you think maybe the riser caused some kind of motherboard damage that is now keeping the 3090 from functioning properly?

Aye. The motherboard is like a messenger of sorts between all your devices. If something isn't recognized, that's usually on the motherboard.
The 3060 and 3090 run on the same driver packages; that shouldn't be keeping it from being detected. Besides, if the system hasn't gotten past POST, then the drivers haven't been loaded yet anyway.

I can't ask you to try the 3090 in a different slot - going from the images of ASRock H110 Pro BTC+, there's only one x16 slot, so that's not an option.
Is there no shop nearby where you could try the 3090 there? If you can get the card to work in another PC, then I'd believe the motherboard is busted.

I don't think there was any adapter in the box, but now that I've sent it back I can't be certain.

It's true. There's just one x16 slot and it doesn't have integrated graphics either which makes it difficult.
Thanks so much for your help!!

 

[film_guy01]

Ok. I just made a discovery that might help troubleshoot things.
I was moving the old PSU and saw this:

Soooo, now that I've got a new PSU and GPU and it still doesn't work...I guess this lends support to the theory that maybe the
motherboard was damaged somehow?

 

[Phaaze88]

Oh geezus... that's gone.
So, High Current Gamer 750M? Been around for about 10 years, but I see there's some good reviews on it.

Hydro G 850 isn't quite as old, but it also appears to have done well.


I think the new 3090 is gone too. Check the sockets around the new psu too - you might not have run it long enough for physical damage to appear on the exterior, like on the HCG.
The riser needs to go into the trash bin though.
IF a new 3090 is acquired - straight into the motherboard.

Well the funny thing it the PSU was still working? I ran the 3060 alone for weeks after the 3090 stopped working (I've since thrown the PSU away).

I actually got it working!! I swapped out the GPU riser for a different one, and now it works. That must have gotten fried as well. Still a little strange the 3090 won't work plugged directly into the mobo though, but I won't complain.

Thanks again to you and everyone else who helped! Much appreciated.
