"Fixed" a shady GTX 1080 today. It can't be that easy, right?

I am guessing that a 1000W hairdryer won't do the job? Even if held for a long time?

I am starting to suspect its a bad connection to something. If the card warms up it doesn't crash. But if I take it out of the machine for a day and try and start a game it'll crash.

Exactly what happened the day after I posted the thread, woke up. Installed the GPU in my GF's machine. Ran Cyberpunk, and it crashed.

Fair points, but a key aspect is effectiveness of application. Lower water content means the IPA potency will be higher and the cleaning effect will be greater. 90ish% is the sweet-spot of cost and usefulness. 70% will still get the job done, as would 50%. One just has to use more of it.


True. Care should be taken to avoid using 90%+ on certain plastics.

Yeah im trying to see if i can find a conditioner to restore the color
 
I've had OCCT run for an hour on the VRAM. No errors there.

Kombustor ran for an hour and zero issues there also. WTF?

Currently undervolted at -150 both at core and memory.
 
Could try a cold spray on parts of the board.

Seems interesting, I would give it a try.

I replaced my GF's RX580 with the 1080, if crashing continues I will try this and torching it. If all else fails it'll make for a nice wall ornament. I remember drooling over the idea of owning this card years ago... :D

Also I want to ask you, will an ordinary heat gun, like a DeWalt for an example work fine for this application? I am looking to rent one out, I don't see value in buying a heat gun for this card.
 
$10 to rent, $20 to purchase...
 
The card still works... WOW. -150 on core, -150 on memory and 90% power limit, just to be sure. It seems stable with stock clocks but I don't wanna cause further degradation.
 
If the card works then great, although the die is pretty obviously degraded. Underclocking and undervolting totally helps stabilize a gpu; there's nothing wrong with it. I strongly suspect it is used for mining before... you don't get that much dust and crap inside a normal gamer's pc, although a few did come close in this thread: The Filthy, Rotten, Nasty, Helpdesk-Nightmare picture clubhouse. Some of those pictures always give me a good laugh. However, reflowing might actually improve the situation somehow, as you mentioned tightening the backplate screws actually made the artifacting issue slightly better(although you shouldn't really do that. It might crack the die). I would STRONGLY suggest NOT using an oven though. It heats up the whole card and those resistors on the back might fall off. In addition to that you get a smell of burning crap inside your oven and a risk of melting the 8-pin pcie power connector. You should buy a heat gun and maybe watch some Youtube videos to get a better understanding of how to reflow stuff. Also getting some thermal pads and applying them to the VRAM might help, as artifacts are usually associated with them.

But maybe when the GPU and ram is running at full pace the ram gets to hot maybe ?, maybe wrong pads on them ?. Or even a pad missing from some were on the board.

Better to check what the pad thickness is and make sure.

And if you must try a heatgun better to shield those caps as it will damage them and while at it see if the caps are bulging or not.

Yeah that's probably a smart thing to do. Better use some Kapton tape to cover things up. Pay attention to the pcie power connector as well; I've melted one of those while soldering loose resistors on a GTX 750.

Also THIS is what you'll get if you put stuff in the oven:

Not sure if I posted this yet, but here we go.

That's on topic of people with questionable intelligence baking shit on every imaginable occasion. Poor GTX660 only had a malfunctioning PWM controller, before it was put in the torture oven.

If someone is offended by my post and wants to mention some examples of successful "baking", please move on. I am short-tempered. :nutkick:

Yeah, I've been watching northwestrepair, he cuts off soda cans and makes a shield with that. Probably gonna do that if the card shits itself again.

I have calipers, I'll measure the thickness. Any ideas what pads to get, what brand?

The card works now, I won't touch it. It 100% was owned by a miner, the guy I bought it from told me the story of the card. I don't believe it was used to play games.

"I bought it from a guy, he gave me a week to test it, but i didn't. When I tried to play games with it it crashed. Then I messaged him, he told me that the card didn't have an issue when he used it."

I then asked him, have you tried fixing it? And he told me that he tried underclocking it and it didn't work.

I knew it the moment I saw the description. Those mining cards are pretty much always pushed to their limits, it's a miracle this poor card still works at all.
Also, about the thermal pads, this site seems to have a nice list of recommendations Best Thermal Pad for CPU, GPU, RAM, VRM, Laptop and Chipset in 2025. I'm not exactly sure on what pads to buy either; I'm still finding ones for my RX590.

Just ask the company who made the card.
