This is very interesting thank you. I have a 1070 stored because when I bought it my PC didn't detect it 85% of the time, perhaps it's worth checking with the multimeter
Hey man, great videos please keep them going! What gear do you use for your soldering? GPU pcbs suck a lot of heat so even with a preheater I have a hard time removing big components. Also out of curiosity, where are you based? Thanks again!
@@TechCemetery Ah that makes sense they're really good, I need to get myself one of those haha. I was hoping you'd be a bit closer I'm in the UK haha, not a lot of people fixing GPUs around here. Again, keep the videos going, I just found your channel and subscribed yesterday
This was so complex. I would like to have two of these cards to run sli, but probably beyond my ability. Nevertheless good job. Maybe someday I will be able to rebuild two of these cards.
I worked at NCR in Failure Analysis to board level for quite a while. We repaired CPU and other computer boards but I have never seen one destroyed like this one. Great video on the repair. I know these video cards are in high demand but what kind of price would you charge someone who has done this to the board and then sent it in to you to fix not only what was the original problem but also having to correct someone's terrible try at a self repair. They would have been canned for work like this at NCR.
Just stumbled on your videos today I have to say very nice video you explained things in an easy to understand way. Took electronics in college some years ago im 50 now but just went a bought reflow station good MM and usb micro I have like 15 dead cards from the past and or working on pcs for years. I wanna get into repairing video cards and SSD drives. You Video by far taught me the most thus far. Would love to know where you get your schematics or info on what is where or did you just have to learn on your own. You keep mentioning the 10 series cards. So I assume you have a source. Any ways keep it up may become patron.
Awesome video. I have a 1070 ti that had a bit of liquid damage on the back of the PCB. I've already cleaned the card and it works perfectly fine...except the fans never spin up - even if I use Afterburner to manually set the fans to 100% I still get 0 RPM. I've tried swapping the fan from a known-good card over and same story. Any ideas where I should start? All components appear present and making contact.
Really impressive repair!! One question. How did you manage to find the short component on the memory? I guess you used voltage injection and flir or freeze spray. Can I use an 1.5 v aa batery? I dont have a lab psu.
I used voltage injection with a power supply. For a GDDR5 card, 1.5V should be fine but I've never tried an AA battery so I can't tell you if it'll work.
Excellent video and nice work. I have the same GPU and PCB model but PNY manufacturer, I have an issue with the card and I found that there's no readings for VRAM voltage coil. I think that the controller for VRAM voltage is damaged but I can't find the model on internet
I have the STRIX-GTX1070-8G-GAMING card in my gaming machine. LEDs light up and turn on and off at regular intervals, but the fans don’t spin and there is no HDMI signal put out by the card
I've a repair that I'm stuck diagnosing on that I'd live your help on. I've got a msi golden 980 ti that's fans spin and led lights turn on but no display. I tried running in the second slot of a working system but gpuz and device manager didn't detect it. My current speculation is that the core isn't being powered properly but I don't know how to verify that with my multimeter. Your repairs have been a great resource and keep up the good work.
great video ;) enjoyed it! :) i have one question, i bought broken MSI GTX 1080ti. Card was stoping on B2 error. When i managed to press on it, it booted, it could run on 40-50% power/downlclock, but when in normal mode, after any load, it would show artefacts and crashed after 2-3seconds. I managed to repair it, basicaly using 3d printed support and finding right spot to support it. Now i played 500h+ (Witcher 3/Cyberpunk) with owerclock memory and 115% max core power with 0 crashes, basicaly now its working perfectly.. the card looked brand new and the PCIE slot also looked mint.. Question is, any idea what is with the card? .. the owner used it without support, so i think some copper lanes or solder joint got broken.. thank you very much for you answer :) ...ps: i bought it for 30euros, so im pretty happy man anyway.. guy who sold it, knows about computers more then i do :O but that i learned, after i already paid for it.. im asking because i would love to repair it and keep it or sell it and upgrade for RTX card, i can have those from mine job even now for great prices..
Usually with cards like that they suffer from either PCB bending or some form of PCB damage. There are a lot of data lines around the GPU for both the memory and PCIe lanes and sometimes they can become damaged and have micro-tears. For your card, that would be my guess - I'm not that sure as these kind of symptons/errors can be very hard to diagnose.
@@TechCemetery Thank you very much for your reply/answer .. I will keep it and will not touch it ..if it dies i will sell it as spares.. already got mine 30bucks of fun back :) Wish you best of luck with your channel, i will be watching all of your vids :)
Could you tell if the memory is bad and which ones. Could you say how to tell if the gpu is bad and how to test rash of the items. I have a few bad cheap cards and can't find any videos that go step by step on how to check and what to look for. Might you consider going step by step with explanations on what to look for and why. I am sure it would be long, but it could be very informative. Thanks
I know there is alot if guys that has the 30 series card, I have a few, but I also have two evga xc3 3090's that are not working. The previous owner tried to shunt mod these cards, and it didn't work out. Love to send them to you and give you the opportunity to work on these cards. I would also send you some money to support your awesome channel
Holy hell, two 3090s?. I'd definitely look at it if you're willing to send them to me. I'll eventually have a donation/patreon page, I'm waiting to release a video soon which will be shared with another channel where I'll also announce a patreon etc. Do you have a preferred method of contact?.
Hey buddy , Please make a video on adding display connector to a mining card or just swap a GPU core from a mining card to working card like from a Zotac p106-100 to a GTX 1060 6gb Mini as I think it much easier to transfer a BGA from one board to another than transferring the SMD's and connectors ... It would be great video and it will definitely add a lot of view and subs to your channel... Please consider making this video as this is a very hot topic that is discussed on many forums...
For cards like the P106-100, display cannot be added as it is believed to be disabled on the GPU itself. As for RX 470 mining edition cards etc, I'm just waiting to find a card.
would of liked to see you inject voltage to see what got warm i have a shorted memory or memory controller inside the core would be nice to know what a safe voltage and amps to inject i was thinking 0.8v and 1 or 2 amp
Hi, I hope you'll notice, thanks for all your helpful and very informative videos, I subscribed to your channel. I have a question about Asus RX 580 4gb VRM, I found 1 Mosfet was shorted so I took it out properly and the short on the 8 Pin power is gone using a multimeter, however, the 1st 3 pins on the PCIe connector shows extremely low resistance around 160-170 ohms only, and the pad of the shorted mosfet is still shorted, reason why I did not place a new mosfet yet, where would you suggest for me to look further into? How should I trace where the short is originating from? Any help would be grreatly appreciated.
Thank you for sharing ur knowledge whit us again. Can u please make a video about, if the video card from amd, not nvidia, how can i check the memory banks, i think we can't use mats and mods at amd cards.
Subscribed! You wouldn't happen to know the replacement part # for the 4 ferrite beads(inductors) that explode when R33 inductor burns up and the memory vrm mosfet blows. You mention it in the video so maybe you have a parts list handy... ha!
Also subscribed! I found something in internet that says for the L21 inductor (instead of the 4 beads) a value of 0.1uH. I have many GPUs with this same problem....You say this is often compined with a defect GPU?!? Is there a hope, if I replace the R33, the MOSFET Q13 and the inductors L21 (LB12, LB13,LB14,LB15)????
Hi so i have the same card and variant it was showing artifacts i checked it out and found out the problem was originated from the graphics card core/cpu can i do anything about that?
This was awesome work and with proper thermal mods will run perfectly if the one cap is rewired. Not sure where it runs to but seems hdmi and not critical for vcc or pex. A little ultraviolet masking should keep the card trouble free. It seems you made this card valuable again but would not mine with it as I hate mining and think it is equivalent to growing corn to add ethanol to gasoline. It uses more energy to produce than is returned and ruins gasoline for small engines. Mining with cards wastes power and video cards and is a total waste of human resources and video cards.
Hello, thank you for sharing your knowledge with us. I'm having trouble with my gtx 980Ti and i was curious if you've ever meet this problem with other gpu's. Mine isn't brick dead, it has video signal but it restarts my pc or it freezes it even if the pc is at idle or in full load. I have put my gpu in another pc and the behaviour is the same. Some times it restarts the pc even if it is at idle sometimes i play a game and it's ok an sometimes i open a game and it crashes. Can you please give me an advice on what to check? Thank you! In other order of ideas..did the owner of that gpu board played football with it?? So much physical damage...
This card is one very typical for one that is bought on ebay for a small sum as "parts" since those sellers normally just don't give a crap about them.
Hi ! I got shorts on all small capacitors on the upper side of the 2R2 1808 inductor . Can you help me please to find the reason ? 1.8v and pci 1.2v are missing too . On the left side of the gpu , the 5v and 3.3v are present .
And Idk but I would have removed damaged active components or at least put them back the right way before put power to the card so the damaged components wouldn't give fex any 12v or what ever straight into the gpu.
Are we talking the Strix 1080? from r/hardwareswap?. Honestly $175 for a broken 1080 is pretty good in today's market, I would definitely have made the same choice you made.
Hey o/. STRIX 1080, 3V OK 12v 3x OK, 1,8V OK, 1V NOT OK . Different PCB so i cant find the 5V for UP9511p. 2V on UP9511P is OK. Memory Phase no Voltage. What would be the Next Step for Troubleshooting?
There is no next step, the 1V rail is disabled unless the GPU VRM is running. Check whether you have 5V on uP9511p. You can look up the datasheet and map the pin to a nearby resistor or capacitor and check for 5V.
@@TechCemetery Thanks! Looks like Powergood is Shorted for me 5VCC i Get 5V to Ground and also 5V to a nearby resistor; ISEN1 - ISEN8 is 0.03V ; 37th Pin is 1.8V (1.8V Enable Signal for 1V Rail) ; PowerGood (Pin38) is 0.011V PS: BTC & ETH Transactionfees are like 15 USD ^^ you have other Wallets to buy you an Coffee?
You might be remembering it wrong ( or maybe I've said it wrong in the video), but PGOOD (38th pin) is the Enable signal for the PEX rail. In either case, you have a problem with your GPU VRM or phase controllers. You'll want to check that you have a capacitor on the SS pin and that it's not short, and you'll want to check VREF is 2V, there will be a resistor nearby that connects to VREF. VREF is Pin 2 and SS is Pin 28. If neither of those tell you anything, check REFIN on a resistor, it should be between 0.8v roughly speaking. icware.ru/pdf/0004239.pdf
I have an email in the about section of my youtube channel. Send me a picture of the damage, and the rest of the board if you already have it disassembled.
I have a nvidia 1080 ti, it boots up to desk top no problem but can't install drivers, I get something to the effect of"no nvidia hardware" more or less, during boot up it is not recognize as a nvidia card it is just blank, devise manager has it as a "standard video card" anyone ever hear of that???
Really helpfull. I have radeon 6770 1gig ddr5. It had memory phase low side mosfet short. I replaced it and now the external 12v connector short is gone but i donot have any orther voltages other then base voltages 12 and 3.3. I strongly suspect the 12 and 3.3 from bcie bus is short some where. Can u please send ur email address so that i can send the pics of graphic card. Any suggession would be helpful:)
On cards where some voltage rail shorts, it often pulls so much current that nearby/connected components get damaged. I'd expect the card to have 5V somewhere. I'd focus on that.
sound like U'r having loads of fun! something 2 look forward 2! it's fun 2 take dead item's, and bring them back 2 life! frankencard! pcb repair! use jb wield! it's also nice 2 have a picture of the card,showing it naked!! YUP!! it's wonderful 2 see EE's fixing stuff! just wait till U get in2 chip encryption!! I think Utube keeps everything quite simple! watching people fall down stairs, & musical farts!!!good luck...
i have a 1070, the memory voltage is 0, and all the memory is shorted, I don't know what to do about it anymore hahaha. the gpu heats up but that's about it
