Here is a final update on this repair attempt. I was quoted €397 for a replacement GPU chip, guaranteed working, and even though I offered to repair this card with no costs for work undertaken (just pay for parts) the owner felt it was uneconomical to repair. Which in fairness I have to agree. He decided let me keep the card for parts as it would make a good donor for other repairs, and hoped it could be used in the future to fix somebody else's graphics card. From my point of view this is one less uneconomical to repair graphics card doing the rounds on ebay, it will most certainly not be going back into circulation. Luis, if I can help you again in the future I will not be charging for my time, that's the least I can do for you.
Yeah that is what I also said. Question. I understand the missing RAM bank can be in various places, and I assume the GPU BIOS specifies the missing bank location, so if you replace the GPU from another card, how do you know it is ignoring the correct misssing RAM bank?

Hi Richard, This GPU is "very nice" delaminated by heatgun, but also missing one of the RAM IC on the right bottom next the GPU. I hope you can get those spare IC's from China to be able to repair these cards! Regards Marc
Are you sure about it missing a RAM chip? As far as I understand, these 11Gb 1080ti always have 12 places for RAM and only 11 fitted. I also understand that the missing one could be in any position and there are settings in the GPU BIOS to tell it which bank to ignore. How that affects the situation if you replace the GPU and how to make sure it is set to ignore the correct bank I an not sure..... yet 😉
@@laszlomarktoth7492 Yeah it isn't common - AFAIK it is only 1080ti that have this weird thing with 11Gb. I sometimes wonder if it is because many of the GPU chips are faulty from manufacture on one or another of the 12 RAM banks, so they disable the one bank (not always the same one) in the BIOS so they can sell the faulty chips?
Not necessarily. Though it often would be the GPU chip, there could be a short circuit capacitor for example or faulty VRM (low side mosfet short to ground) on PEX. However I would say if you have a short on *both* PEX and 1.8V you can be pretty damn sure the GPU is dead (shorted) This is what I predicted I would find once I saw the heat-gunned GPU and I was absolutely correct.
@@LearnElectronicsRepair On 1.8 rail I have 1.8V and 130 Ohms (pretty low!). On PEX there's 5 Ohms(!!!) and 0V . Should I inject low volts to PEX inductor to found what's hot?
Hi Richard, how are you? Your channel is great and educational. I love it. I would like to ask you can you remove a gpu chip with just a hot air gun ? Kind regards
Oh that is really not possible. Even with the Quick 861DW which is a good hot air station. It should be possible with the Quick plus a good infrared preheater, but my small hot air preheater (Kada 853B) is only capable of getting high thermal mass PCBs (such as GPU) up to about 90C which isn't hot enough. I have tried this before with LGA socket removal, which is pretty similar and I made a video of that - have a look. If you can't get enough heat evenly into the entire PCB, you may still get the BGA off with a powerful hot air station but the PCB delaminates (plus you are likely to strip some pads off as well) and is then useless. th-cam.com/video/x9Xiv19Kx-8/w-d-xo.html
Hi Richard, First of all, thx for the time spend on it :) The history is quite simple. This card was bought by a friend and he has been "scammed". The price was below the market and he thought that was a good deal... which was absolutelly not... He try to get his money back but with no success... The missing screws was my fault because I dismounted the fans and the back plate as the card was not functionning and I loose some of them. Thanks again for your time :)
Thanks for letting us know the history of this card. If it was sold as working, he was certainly scammed. If it was sold and described as anything other than spares or repair he was scammed. If it was spares or repair, well it could be used as donor for spares (donor board) or could be repaired by replacing the GPU chip (depending on any pcb damage) so it fits that description. Sorry about the bad news, he certainly got his fingers burnt. Please email me and let me know what to do with the card.
Depends on the price I am quoted and the owners decision. I have the equipment to change the GPU as you probably saw on previous videos. Anyway I will post updates in the comments section and pin them. If it ends up being replaced there will certainly be a follow up video. The first thing before ordering would be to remove the faulty GPU, check out the PCB condition under the GPU and make sure all the DQxx connections to the VRAM test OK (basically checking the RAM chips are probably OK). All depends on the owners decision before I do that work but will let you all know anyway.
Hello, i bought the same used card as on video, while checking for shorts i ran into kind of a problem where my multimeter reads or not some ohms depending how i put a probe on the part, also a capacitor that is above your index finger at 7:01 (the one thats kept alone above the screw hole) is missing could that be an issue keeping gpu from getting detected? (I know that the video is one year old, but I appreciate if you actually see it)
Hey LER, have a question, I've come upon a certain issue, after replacing the thermal paste on my laptop (XPS 9570, which I got for a good deal), I forgot to connect the fan header, and upon playing games, it started crashing, so I was like what's goin on, until I turned off my OC and noticed the temps were quite high, then when I restarted the laptop a DELL thing started and checked for device performance and status, and said that gpu fan was not working, ... so, lol, after connecting that I went back in and the crashing continued, but now it only crashes above a certain OC threshold (like I've degraded the performance and the chip is damaged), What could the issue be, could something have gotten damaged in either the chip or maybe the power phases that regulate or adjust the power lines to the card? It only seems happening now after a certain threshold (where before it would be okay), now after a certain threshold it just crashes, like it can't go further than that, so somewhere along the power delivery there's gotta be a fault and I'm worried that the un-fanned and OCed gaming attempts with several crashes not knowing what the issue was, could've caused damage to either the chip or some power delivery lines to the chip or I don't even know, any help would be appreciated! I don't have a multimeter so wouldn't be able to check (but want to buy one), if it were a cap (those are the ones next to the chip right? On the green background (as per your video), then those could be very hard to replace right, if at all?) Anyway, any and all input is very much appreciated, and nice video btw. Thanks, David.
@@remartogonon5606 The PSU tester usually does not load the PSU - I use a 100W 2 Ohm resistor. This puts about 1.6A load on 3.3V and then it should stabilise all the other voltages. Try this before you spend any more time trying to diagnose the fault

No idea John. As I mentioned I also ordered another milliohm meter, the cheapest one I could find, not that I need two of them but purely to entertain you guys. 😁 I'll be making a review/comparison video of the two once it arrives to see if there is any reason to buy the Vici VC480C+ vs cheaper options and to investigate how useful these type of low resistance meters actually are for short circuit finding.

Good video. It will be interesting to see what happens with this one.
Someone repaired it for good :D 1080 ti is an 11 gig card. There has been no RAM chip at the empty position from the factory.(for the comments)

@@LearnElectronicsRepair it is always the same bank that is empty as far as I know. Your memory chip brand is micron by the way.
@@LearnElectronicsRepair I would pay to know how to configure bios to ignore specific memory bank.
50 bucks via PayPal.
Anyone ?
@@tonycstech thatt not possible. Banks are configured via gpu internal firmware, this information would cost more like 500k.

The coil below the memory is PEX, the other one is 1V8, if both are shorted the core is most certainly dead.
