GPU suddenly died?

[Kodehawa]

Hello!

Seems like my GPU suddenly half-died while transferring it to another system. Its a sort-of old RX 480, and now any kind of load will make the GPU black screen and put the fans at 100%.

I changed the PSU, so I went and tried the old PSU to power the system (known working before change) and it exhibited the same behavior.

The only way I can get it to not crash is by putting the power limit to -40% which limits it to 80W and underclocked it to 1100MHz, with a hefty undervolt. If it draws any more than 90W, it will crash inmediatly.

I imagined it could have been the PSU but old known working does the same. Guess the GPU just suddenly died, but I want more opinions.

When it crashes the system is still responsive (ex. can still change volume and it will reflect)

Thanks!

Kinda seems like the card is on its way out. Maybe a capacitor is blown or a MOSFETs is going on the card. Clearly its a power delivery problem.

I'd guess it is a fractured solder joint on the GPU that got disturbed on transfer, but that does not really help much unless one intends to reflow (with flux).

Thanks for your suggestions! They all make lot of sense.

Video of the issue:

You can see the power meter going crazy and the simulation stuttering a lot. I used furmark because that causes an almost immediate crash. On a game it takes about 30 seconds.
Fan speed reports 0RPM on the video, but the GPU fans were moving. In fact, weirdly now it only reports 0% or 48%, nothing in-between.

Well, guess GPU just died suddenly. Thankfully a new GPU is on the way, which I bought about a week ago.

The situation is kind of a pain though, I moved the GPU to the new system to have a *working* new system haha. Unlucky moments :<

Update since you both replied, it was indeed just the GPU. RX 5700XT arrived today, and it's running without any issues.
Kinda unfortunate it died while transferring systems, though.

Thanks you both.

May your new gpu serve a long time. Good luck.

Guess it was my turn next. My gigabyte 3080ti vision suddenly died when playing elite dangerous. Had the exact same issue, screens went black, fans to full liftoff but the rest of the system was still on. Couldn't restart again with the gpu so i tested my old gpu that i still have, a gtx 1080, and it works.
Luckily i will now get a 4070Ti from the warranty but still, these stuff sucks butt.

ESD

I can understand ESD when transferring a card, but not when it is in place.

 

[Kodehawa]

I doubt it was ESD in my case too just because the conditions aren't there. Hard floor, extremely high (>80%) humidity, no carpet or anything similar, but it's pretty much impossible to rule out on what happened to my card.

I'm more inclined to say it wasn't completely related to the transfer, as it was giving issues (random black screens with full system freeze) since 2019. Card accompanied me since 2017, so at least it lasted me a good 5 years

There was some pretty bad corrosion on the connectors connecting the PCIe power pins on my card. I imagine it didn't take too well to living close to a coastline for so long, lol

May be that some power phases are faulty. Either some MOSFET or DrMOS, gate drivers, resistors, capacitors and so on.

 

[delshay]

I would give the GFX card contacts a clean. Seems strange it would died just by transferring it. My opinion what I think broke, if indeed it is broken, is solder contact may have cracked somewhere. These things do happen as the card age.

MOSFET Q505 doesn't look so good. Not too sure tho.

I could scrape it off, was kinda caked on there (not just "on" there), but the leg still has a burnt color.
If anyone could confirm that the MOSFET is the culrpit (or if it looks like it would be, you never know), so I can order the part and ask a friend who has the equipment to help me with this

Steps to further nail it down appreciated too. I don't reaally know electronics.

And yes, there's no reason to save it, but it accompained me for 5 years so... might aswell?

If you suspect it's a FET then put a multimeter across it & check for "open circuit". While you are at it, you could check those zero ohms resistors for the same thing, but I don't think that's your fault.

Have you tried a brand new install of windows? you could also do a windows "online file checker" just to be sure you don't have any currupt files..

If you suspect it's a FET then put a multimeter across it & check for a short. While you at it, you could check those zero ohms resistors are not open circuit.

ty. will test

edit: saw your edit, ty

Yes. Also my 6700 (and the 5700XT I had for a whole 5 days) works completely fine.

I'd guess that was just flux

Could be. I'mma test for open circuit as the other guy say and report back once I can. Need to get a hold of a multimeter tho.

If you got multimeter, check:

1. Resistance between D (positive) and M (negative)
2. Resistance between M (positive) and S (negative)

Edit: Unpowered of course. Tho IMO it doesn't look that suspect.

When fault finding I always use "driver only" from the install option. It will not solve the OP issues thou, but this is standard practice here when fault finding.
