Problem with my used RX580 4Gb

[Adorable Cat]

(just copy/pasting this from my reddit post so I hope the formatting doesn't get all weird)

I bought a used RX580 4Gb on Ebay in January and I've been having a problem with it whenever it's under load. My screen will just go completely black and the fans will ramp up to 100%, and I'll have to hard reset (although what's weird is that I can still hear sound like normal.) The rest of my system that matters is an i7 3770, 16Gb DDR3, Asus P8B75-M LE motherboard, and a 550 watt EVGA B3 PSU. So far I've tried:

-Clean driver install (DDU)

-Re flashing the VBIOS

-a completely different system (i5 2400, some HP motherboard, and 4Gb RAM)

-cleaning the card, replacing thermal paste, and running on an open air test bench

-Undervolt (it still crashes at -150mV)

-different windows installations

So far everything I've tried still hasn't worked, so I've already contacted the eBay seller (although if I can get the card to work somehow, I'll cancel my refund request) can anyone help me?

check the temperatures, specifically GPU temperature if you no clue.

under load for how long? 100% usage?

try if under clock helps

black out could be caused by unstable psu, but unlikely for 2 pc...

My go-to tester for this so far has been Superposition 1080p Extreme, and it has the problem right as the loading screen finishes.

When the card lasts long enough for me to get measurable temps, they're not unusually high (high 60s-low 70s).

I tried an unreasonable underclock (1060Mhz from the normal 1380). I'll try reducing the power limit real quick (I wanna finish typing this before I try again)

I also tried with an abomination of a setup with a second PSU only powering the GPU and it still crashed right as superposition started 

 

(no it's not a problem with superposition, it just gives me the quickest results)

 

update - with an unreasonable decrease to power limit in MSI afterburner (-50%) it managed to complete superposition, although at such terrible framerates I may as well just use my GTX950 until I get a new GPU. I'll keep editing that setting and see if it helps

look at how to disable "ULPS".

You can do that with for example MSI Afterburner.

Well does it happen in games? If it's only happening during a stress test, then stop using that stress test. Also try Stefan's suggestion.

I tried and it did nothing (in superposition and games)

 

I think it may just be time to accept that this poor GPU was defective when I got it and just get a refund. I'm thinking now that I have more money I'll go for a 8Gb model too. Thanks everyone who gave ideas.

Maybe VRM overheating causing it to shutdown? 99% of cards don't have a sensor for that so it's up to visual inspection, but it is possible that the thermal pad responsible for heat conduction from VRM to heatsink fell off or somehow failed to make proper contact.
