I don't know if there is a thread for this yet, but I didn't see one.


This is a sold eBay listing.
Screenshot_20180708-142809_eBay.jpg




This was the items description:


Electronics recycling can sometimes lead to uncovering treasures of the past, or incredible hardware of the modern day.

Most of the time, these finds are a whole bunch of fun, and we often get some neat stuff.

Sadly, this lot is not one of those fun finds.

These cards have gone through hell and back, and are borderline destroyed. There is evidence of water damage, dirt, several missing SMT components, PCB damage, etc.

I am optimistic in hoping that someone can put these to some sort of use, as it'd be a shame to just scrap them.

This listing is for one lot of 4 PCIE video cards FOR PARTS OR REPAIR

Due to the condition of the items being listed, there is NO GUARANTEED LEVEL OF FUNCTIONALITY.

The lot includes:
EVGA GTX 980TI 6GB 06G-P4-4990-BR
Dell Nvidia Quadro 4000
HP Nvidia Quadro 4000
PNY GTX 10?? (Appears to be a 1080 or 1070, but is missing the backplate, and has no label. This card is in the roughest shape)

We did not attempt to test any of these units.

yea, makes one wonder if people are not just stupid but absolutely stupid, drunk, drugged out or the seller bought his own listing, then does refund and that results in positive feedback and no fees (or shipping) paid.

Unfortunately, eBay has become a piss hole where stupid high prices on used computer hardware prevails (mostly motherboards, CPU's and GPU's. Other item can occasionally be found at an ok price but most often ... just buy it New BESIDES, you'll have a warranty)
 
ok? Sorry, I'm failing to see the point of this thread. Was it just to show people bid on broken shit?
 
you may be suprised to see how much can be done by extremely smart people with the right tools. I would HIGHLY assume the actual chips on those cards are still functional and with some cards it may be worth it to find another card with a intact pcb but a burned up chip and swap them.
 
VERY few people could pull anything like that off and nobody at all without specialized and very expensive equipment. A burned up resistor, capacitor, MOSFET, sure, that's doable by technical folks with decent soldering skills. But a GPU swap with a thousand tiny contact points? No chance.

it's easier than what you think if you have a reballing station, and those can be cheap for the manual models up to very high dollars for the automatic models.. any decent electronics technician have at least one of those.

these are few examples:

I once bought a 7970 on Craigslist for $20. The seller was upfront that a drink had spilled on the card. But the card was just released a few months prior and was still selling for over $400. I figured I’d take a shot and buy it. Maybe I’d be able to rma it (xfx card). So I brought it home and called xfx. They were like it has water damage. The previous owner called it in and told them a drink spilled on it! Oh well, I got a $20 show piece.
 
Exactly how do those reballing stations work? Got any youtube videos of someone using one to replace a GPU chip?

So it uses hot air to remove/install the chip?

issue is not remove/install the chip but the correct placement of the tiny balls.. it have to be a perfect match that's that's the hard part.

manual method require to use a lot of heat gun not good for GPU) an stencil which require to be purchased or be made with another machine, lot of flux and desoldering wire mesh, (also lot of patience) automatic reballing station can do the chip removing (as the name say) automatically with a perfect temperature control and automatic BGA removing, some machines (and this is where most of the price vary) can do automatic BGA replacement (not only remove but also install it) so the usage of the stencil won't be necessary, however one of the most important part it's the correct temperature control which where machine shines with a combination of infrared heat focused flow.

look at this video, it's a factory-like quality BGA replacement.

not nessisarily perfect but withen 1 ball or so. if they are close enough the serface tention of the solder will pull them together
 
No worse than buying a lottery ticket, I'd throw 20 bucks at it. That one looks more like the cooler got messed up more than anything. People have brough Xbox 260's back to life by wrapping them in blankets and people have revived video cards by putting them in the oven. Who has broken that many cards? lol.
 
I LOVE how this has developed,
Want a reballing station, and some day will have one.
Also intend on seeing what it takes to turn a GTX into a quadro (More VRAM, BIOS mod, specific missing hardware)

no real point anymore but people used to be able to mod a gtx card into a tesla quadro or titan by changing the resistance levles of the straps that defign what card it is. thats for nvidia amd is still just as simple as throwing on the difernt vbios and it will often work fantastic.

And that's how Terminators are made :p

Seriously though, really interesting video, thanks.

I saw some guy who turned a 980Ti into a fully custom Titan X by moving vRAM and GPU chip into a fully custom 980Ti PCB (EVGA classified), turned to be an amazing overclocker Titan X GPU with all the extra cooling and power delivery.

I used to work with someone who I know used to hand solder small SMT parts and BGA chips and who I think reballed one or two small ICs just to prove he could do it; but for something as big as as a GPU die proper tools really make a huge difference in odds of success. Especially since off by 1 or shorted pin errors could connect Vin to Ground and let the magic smoke out.

Yes.... But I want to try it at least once.

Using a GPU that you are okay with losing would help :-P

good to know there are such honest people like you floating around out there who do what their [H]ard|Forum ID indicates
 
I work at a electronic recycling facility. It's absolutely amazing what comes through. Guess I should pull some cards and chuck em on ebay "as is".

PLEASE post pics here if you can..... I like the cringe

Well most don't have a lot of horrific physical damage, they simply don't work. I keep an eye out for anything interesting, pulled a couple Quadro K4000 cards recently that looked pristine, but one would not output any video at all and the other had heavy graphics corruption. Oh well. :(
 
I would love to get my hands on some of those....
It would be great to work with trashed Hardware to see if it can be fixed.

I really have wanted to bake a card.
I'm not going to do it to it fully functional one, why would you try and fix something that's not broken :-D.

And then if not fixable, I would love to swap parts off of different cards....


Damn I wish I could work there for a few months

I worked as a diagnostic technician for 2 years at one point doing board rework of various equipment. I still do it with computer hardware/electronics as a hobby. It is cool as a hobby but aweful as a job. Every task is almost always a different fix but the issue is even if the item is fixable will it take more time than it is worth? It also means revenue loss when you can't fix an item. So to put it simply it sucks as a job to rework boards but it is amazing as a hobby.
