Gigabyte advising they cannot find a fault with RTX 3090 when I RMA'd due to BSOD

[hobib_ali]

Hi Guys

So I have this RTX3090, suddenly every time I run a game it randomly crashes to a black screen rendering the PC unusable until a manual restart is done.

I tested it on my work PC and it does the exact same thing.

Playing stalker 2 is a no go as within minutes it black screens the whole PC

The card had like 6 month warranty left on it so I sent it to Gigabyte UK as a RMA

They advised they tested the card with Time spy extreme for hours and that it works with no faults, they sent me a screenshot of the timespy score

So ive responded advising I wouldn't send back a card if it was working, especially when I need one now so bad, I explained that it crashed 2 PC's and that I know when a card has malfunctioned as Ive owned many GPU's.

I dont know I feel like its not been checked properly as I know as soon as it comes back its gonna do the same thing all over again.

Any thoughts on this?

I got something similar with my AMD 7900XTX, random crashes, black screens and fans ramping up. Tried loads of things but what ultimately sorted the issue was replacing my seasonic 1000w PSU (a good few years old by then) with a new modern seasonic 1200w one. Probably overkill but I think it was more likely the newer one was able to handle transient spikes better.

No issues with old psu and old GFX card (radeon VII) so think it was down to just how the later cards handle power draw, or the old psu just getting tired?

its not the PSU because I have used a borrowed 4090 and a 2080ti and both of the cards works flawlessly with zero issues on my PC, otherwise I would have had at least a crash or 2 on my current set up

Right now Im running a 5080 and again zero crashes, but as soon as that 3090 goes in it crashes with a black in screen in minutes

should have sent them a video of the card playing up that way they can't bull rap you.

well I have explained that I wouldnt of sent an RMA over if the card was working, it crashed on 2 PC's so Im certain its the card, I think time spy and actual gameplay may be a bit different?>>?

Do you have an ATX3.0 or 3.1 PSU?

The 3090 has wicked power transients that cause huge voltage spikes, which makes PSUs ‘correctly’ shut down if they aren’t designed to handle these.

I had a gigabyte 3090 that I RMA’ed for random ‘black screen / restarts’ during games. I eventually swapped the PSU and this sorted everything.

Edit: view windows event viewer and see what the black screens are logged as. A power kernel error, I expect.

I had a look and its doesnt specify other than saying a crash and hard power off report

the card was crashing every time I fired up stalker 2, but Ive had 3 cards after the 3090 and they worked perfectly, zero black screens, the 4090 I used every day for around 10 days and it didnt crash or lock up my PC

It's the year 3074 and the OP still hasn't answered what PSU they are using

ive got a Asus ROG Thor 1200Watt Platinum PSU, its new and Ive connected to the 4090 and 5080, zero crashes zero black screens, it cant be my PSU otherwise I would have had black screens with the 4090 and 5080 right?

Can the OP run Timespy extreme for hours. If not, PSU.

Gigabyte are saying they ran Timespy Extreme for hours with zero issues, 2560x1440 yet I discovered you can use the internet, browsing and Utube example with zero issues but as soon as you start a game Stalker 2 @ 4k full settings it black screens on me, did the same thing on a work PC, Lenovo P620 which had a 1000watt PSU and an already installed RTXA6000

So I put the Ada 6000 back in and decided to RMA the card

If it was the PSU then surley the 4090 and 5080 would have black screened right?

No.

The 3090 has sudden, brief, massive power spikes that can trigger the over current protection of a PSU.
This is the PSU working as intended. It would look like what you are describing.

It's a quirk that is specific to the 3090.

really?

if this over current trigger is not considered abnormal? as in if it keeps on crashing a PC and a physical restart is needed to get it back up how will people use this GPU? I had a 3090ti for about 16 months and it didnt display this issue, also the gigabyte 3090 didnt display this issue after like 2 years of owning the card but this appeared suddenly in the past few weeks?
