I'm a regular viewer of NorthRidgeFix and somehow I stumbled upon your channel. Glad i can find another tech who are so talented like you! I absolutely will looking forward to your other repair videos!
Northridge was supposed to send me a bunch of cards for repair. Once we agreed, I have not heard back. Not sure what his deal is but from what I understand about his operation, 90% of all GPUs on his shelf he gonna call a no fix while in my case, 90% is a fix. Just takes few days and I charge a flat fee.
@@northwestrepair yeah, Alex is a very busy person and with that much of work that has to be done, he rather choose to deem "no fix" than to actually fix it (only for devices that takes too long time or truly unrepairable) because it's not worth his time to spend. I bet he work on tens or more devices on daily basis.
That film left on the pads is why some of them, e.g. Gelid, have something printed on the film. Gelids only have them printed on one of films so peel the blank side off first and stick them on, that way you can see which ones still have the other film on before you assemble the card. The resin bonding for the VRAM chips nearest the PCIe slot will be to stop them peeling off as the PCB flexes. Loads of prebuilt PCs have had that problem due to the G forces the cards endure as they're being couriyeeted.
That black residue around the memory chips is called underfill. Yes, they use it to strengthen the structure of BGA components near PCI-E socket, where bends can occur. Some reworkable resins can be removed with heat, whereas others, like the one shown in this video, are impossible to remove without brute force.
Another key note, that is a Micron variant. The Micron 2080 Ti's were bombs in general. I bought a XC Black, the first two I received were Micron, and artifacting out of the box. The third came with Samsung memory, and have had zero issues since (2020).

Expecting the average consumer to be able to solder at this level of skill just isn't going to happen. We should repair more and I always open broken tech up to give it a shot, but such small surface mount components require incredible skill and precision - not to mention all of the equipment needed, from a quality heat gun, multimeter with needle probes, a good soldering iron (usually with temperature control) and a thermal camera - plus buying the memory chips, which are often so expensive in anything other than bulk quantities that would leave consumers with a mountain of useless extra parts that consumers have no incentive to do it themselves. Repair needs to be made easier and cheaper through right to repair initiatives, not complaining that the average person somehow hasn't invested hundreds of hours practicing SMD soldering, or into nice repair equipment and doesn't have several donor boards lying around.
its already know that early micron memory on 2080 ti failed a lot. tons of news stories about it when the 2080 ti launched. gave the card space invaders artifacting.
FYI, this residue is called "underfill" and it's purpose is to avoid/lower risk of cracks in solder joint's if it's getting under physical "stress". It's usually applied in devices which can exhibit that (like phones and other handhelded devices). Apparently wohever designed that, came to idea that memory chips near PCI-e slot are also at risk of that so that's why it's there.
That 2080TI ,they had a waterblock on there and put the stock cooler back on later. That's why the screws are mismatched and why the thermal pads are all freaky looking. The stock thermal pads look very different.
There are times when I'm envious of someone's knowledge and expertise and this is one of those times. In saying that - well done for the fix and i hope you see some reward for your efforts. I have a 1080ti which needs repairing, i genuinely believe t it can be fixed - I just don't have the knowledge to even start diagnosing where the problem stems from. The card is still operational but under stress it crashes.
I have almost the same issue but with an R9 280X that for some reason, I was playing call of duty warzone before the cold war forced integration and suddenly image frozen but the system didn't recover and while booting, the gpu never worked again and I had to remove it because the system was getting frozen before the POST so I think this gpu died or something horribly wrong happened and it needs dedicated repair, that would cost me way more than what I spent to buy it and some people either don't want to repair a gpu or they don't know or can't be bothered to order the parts necessary for the repair to be done.
try to underclock often times it just cant hold certain clocks anymore or try adding voltage at lower clock frequencies in frequency graphtuner from msi afterburner.
This tells me so much,first how good you are at diagnostics and secondly,the reason for resin around the memory, is because they run this memory so hard it gets hot enough to soften the BGA solder,the resin stops the memory moving around, that explains why so many fail just after warranty, i used to buy high end cards,now i dont,just money down the drain.I remember the early days,when graphics cards usually outlasted the PC,the only reason to replace a graphics card back then,was to upgrade.Seems like everything now is made by, make fast buck companies.I liken it to buying a ferrari,it's great at waht it does,but you pay the price for this performance & its engine isnt going to see many 10000 of miles,before a rebuild.Great vid,thank you.
That's a BGA underfill and is not there because the solder is melting. The chips would stop working long before it ran hot enough to do that and holding it in place would only do so much anyway. Underfill is meant to relieve stress on the BGA solder balls. Usually to minimize the effects of thermal expansion over time but Nvidia doesn't really care about that. It's only on the chips nearest the PCIE slot because they're the most prone to damage from board flex. I suspect it's also there as added protection for OEMs and prebuilts shipping these pre-installed in systems. It's also likely part of the reason Nvidia has moved as many chips away from the slot as possible on the heavy 30 & 40 series cards.
@@JJFX- ok thats fair enough,i was thinking low temp solder 188 deg c,as i would imagine it would allow for a very small amount of thermal movement,under overclocking for instance,ive also had laptop system boards with resin around memory BGA's ,i wonder if it's the same reason. Do you think high end graphics cards are always going to have a high failure rate because of thermal stress,or is it something else? As for the small SMT tant caps,ive repalced a fair few of those, bit like the larger ones,they go short circuit as well. As the old saying goes,the cooler you keep components ,the longer they live.
@@enoz.j3506 Well this is almost certainly all lead-free solder which really melts well above 200C. Issues with the GPU itself tend to be on the large dies as thermal cycling has a more significant impact on the substrate joints over time. Different parts of the die heat up at different rates so the effect of thermal expansion become more significant. How the die is bonded to the substrate, the type of underfill combined with acceptable production tolerances have been difficult to get right while staying economical. This a big reason for the infamous Xbox 360 RLOD early on. Hard to say how modern chips will hold up. Package engineering is very complicated and Nvidia has made plenty of mistakes in the past. However advancements in underfill and BGA assembly have come a long way since their more notorious issues. That said, they are dancing with the devil by using bigger and bigger dies pulling more and more power. I definitely agree that those looking for longevity should keep everything as cool as possible. IMO, putting a full size water block on $1000+ GPUs capable of well over 350W is a no-brainer.
yes the thermal expansion in all dies is very difficult to control,if you think of the 28 billion transistors+ ,it is amazing it lasts as long as it does, yes i remember the xbox problems.
@@enoz.j3506 Yes it's pretty mind blowing. As processes get smaller and smaller it'll be interesting to see how the transistors themselves hold up. Interestingly, Nvidia's vcore target has largely stayed the same since Pascal despite going from TSMC 16nm to 5nm now.
Bought a used Strix 2080Ti for $274 (incl. an installed Strix waterblock + the original OEM shroud/fan/heatsink assembly w/backplate). As I do not do water cooling, I removed the watercooler for resale and installed the air cooling assembly/backplate (after a deep clean, thermal-pad check, and re-paste). Unfortunately, the white shroud for the male FAN power connector to the GPU board was damaged (as-is) and although the pins make good contact, the shroud does not securely maintain the connection. Tie-wrap to the rescue. Done. Now the card runs perfectly well. Benchmarked SAT. I then did an under-volt using MSI Afterburner...for safe measure. GPU runs cool and stable...very happy with a fine 2080Ti that cost me, NET, about $220.
It's interesting to watch your repairs. Wish you good luck. Some gpus repairs maybe won't pay back, but maybe some new experience you get push you bit further avoid any more same symptoms on bad/dead stuff. It reminds me my old GF 8800GTX died after 2y heavy gaming long 10 years ago. I put it to service, was something like heat treated and UV too(Not rly sure), it worked again for another 6mo until it died again. That previous 20-25USD(500CZK) repair cost I didn't wish to repeat. That was time to get new gpu.
That silicon around the bottom memory chips is to protect them from coming loose/solder joints cracking from the sheer weight of the cooler that the GPU manufacturers started implementing quietly a couple of months into production.
Dumb question: Assuming that the warranty is not voided with this kind of teardown, does the unpeeled plastic cover on the thermal pad at @6:53 constitute "faulty workmanship"?
can you explain more to depth about why 8 ohm on that coil means memory modules dead ? is it too little resistance ? too much ? there isn't supposed to be resistance maybe without coil ? its all a big mystery for someone like me with basic understanding.
I added a shit ton of additional pads to my 2080 when i got it after replacing the old ones and it still gets crazy hot on the back plane. Probably going to have to add heat sinks to the back shield with thermal adhesive.
Do you know if other GTX / RTX or even RX cards tend to have that same type of Micron vram chips? Asking so I know what to look out for when purchasing used GPUs.
Browse through his older videos. He already did some repairs and mentioned it there. IIRC it´s related to 2018 manufactured Microns. You will not find it out, tho. At least not without full GPU disassembly and thorough cleaning of the chips. GPU-Z does not offer this kind of info.
Crazy it got resurrected from the grave. Alot of knowledge and skill here. Remember there was a big thing with this card about the memory having alot of problem. RTX 2080 Ti owner here and I haven't had a single issue thus far and I push the GPU to the absolute limit. Still, can't wait to eventually grab an RTX 4090 this upgrade
Sure. Struggle reading? Different type of memory were outfitted on the 2080 Ti depending on the purchase people could end up using a defunct version destined to be RMA or have severe longevity issue. Luckily I didn't get this particular chipset Micron or Hynix I got Samsung, but this could be an issue going forward. Not that would I expect you to comprehend this, drug addict.
@@nicekeyboardalan6972 i think 3000 series will face different set of issues, mostly due to all the shortages, that were happening during their manufacturing. I expect something similar with AMD cards too. Many companies had issues during Covid shortages and were using literally anything to make their products.
As someone who got a comp sci degree, therefore only knows programming, not hardware, I like your funny words magic man! Note: I know basic hardware not GPU and such
your CS degree DIDN'T teach you basic hardware? what sort of CS degree is that? I had multiple modules dedicated to hardware. Of course the electronic engineers have more in depth knowledge, but we were expected to be able to design (i.e traces, component positions), fabricate (milling etc...) and assemble (surface mount inductors, caps, resistors etc...) a PCB and accompanying hardware, and program the MC on said PCB to control any accompanying hardware.
@@lewisd56 I am currently doing mathematics and computer science (UK joint degree) and I never got any hardware course, even compilers were exclusively taught to computer science people. I've mostly just had theoretical stuff as compulsory courses and the rest to choose myself. And among the options we get, there's basically nothing hardware focused. Still, I have been studying more on the side because I'm afraid of coming out useless from university even if I have pretty good grades.
@@leonro UK computer science degrees too, (BSc and MSc), I had dedicated modules for embedded systems (C++ programming arduinos and other MCUs as well as designing accompanying circuitry), even had a module that went into specifics of logic gates and operations in a CPU. The MSc took a step back from the hardware, but I specifically picked the hardware oriented modules, so ended up working with more complex embedded systems and designing a whole PCB from scratch.
They lasted the warranty Period. Wouldn't be surprised if Nvidia knew that and used them anyway so they can sell more Cards, given their usual scumbag behavior. EVGA pulled out for a reason.
I've had two cards die since I bought mine in 2020. First two cards were PALIT 2080ti Gaming Pros, both died due to issues with the GDDR6 memory - pretty serious problem from what I've heard from other 2080ti owners. Sucks even more that the RMA process takes around a month due to PALIT being in china. Thankfully, they ran out of PALIT 2080ti Gaming Pros to send me last year due to the 3000 series coming out. 😂 They sent me a PALIT 2080ti Gaming Pro OC which is a card that costs £600 more than the £999 card I bought due to much higher quality components, thermal cooling additions and a much bulkier design for heat dicipitation. Haven't had the same problems with this card as the cheaper ones (touch wood), so I'm assuming it's due to thermal performance or the issue was fixed post-june 2021 (first two cards died within 4-6 months).
Repairmire:Diggie digi good work partner if i were near you would buy this art sadly we are far from each others always watching your videos for learning something new keep it up my friend
When watching any of his video's you can see the results of a true technician not somebody that thinks they know what they are doing! He has repaired a card for me with 100% excellent results, so if you have a card and were worried about his honesty or work ethics fear not he is the best !
Remember Micron from 2019? It has big troubles for 2080's as Hynix GDDR6 1gb modules for 3060ti. Yet appearing after years of service. Noone is safe from such things to happen, sadly. It also depends on cooling too :p
Well, I guess it's beware if you're even buying something like a 2080TI in 2022 going into 2023. However, it would appear that you're doing those who would go that route a good service with this video.
@northwestrepair could you explain to me how to find the gpu schematics showing the layout and values of each component like the one shown in this video? Also how do you know exactly where to touch your voltage tester probes when looking for a short in memory, resistors, vrms ect..? Would you be willing to do a video explaining how others like myself can get a beginners guide to checking for damage/ short circuits using a voltage tester to check for ourselves? Any tips or advice would be greatly appreciated. I genuinely enjoy watching all your videos and each one inspires me to do some troubleshooting myself (I have a decent but still beginners level of experience with electronics) but i am to nervous to attempt anything more than a thermal pad/ repaste on any of my GPUs.
with the resin on the bottom memory ic's... I think evga might have determined that the pcb flex near the pcie connector plus thermal cycles leads to those sm components breaking contact.
Makes me wonder how my 1070 is still chugging along with almost no issues. A motherboard swap when I upgraded from my r7 1700 to an r5 5600x got rid of intermittent snowflakes... Why? No idea.
This is why ebga has stopped producing GPU. I have a 1 year old 3060 ti sc gpu that I suspect memory has died. They sent me a replacement and not even a week after I have artifacts and cannot be reinstalled anymore. Pretty sad.
micron memory chip since the beginning always have issues in 2080ti mine die like in 2 months of usage in 2018.I Remember telling EVGA to replace it for a Samsung memory chip don't want any Micron memory and since today still using my 2080ti with Samsung memory.
i took my 2070 super apart and the pads on the memory and vrm was fucked, 4 different kinds of pads, most of them not thick enough or too thick and also like a thermal puddy that was used ontop of thermal pads in a few places, and just too clarify this was a founders edition card, glad i took it apart before i really used it
That's what happens when you're a kid watching Linus Tech Tips. You replace the thermal pads for no good reason, improperly of course, and you also put liquid metal on the GPU for no good reason.
How do you get these diagrams? I'm new to this channel, I will spend some time looking through what you have available this weekend. I watched Rossman for years but I will never get into a situation to mess with apple products. This is way more along the lines of somethin I would love doing.
Nice video. I recently had a problem with my 2060 where the first November update caused an issue and I could not solve it. Important: I have never clocked my PC's components. I have rolled the drivers back, reinstalled Windows 10 and tested multiple working components from another PC. When the graphics card was tested in another PC - it was the same issue. It is weird, because I can either play for 3 days, 5 hours or 2 minutes. The problem was random and the temperatures were always normal. I have stress-tested it and most of the time it pushes through the test with no issues. I have even replaced the pads and the paste on the 2060. The original paste was almost rock solid. But even with that - the card never exceeded 85° Celsius. It still holds that temperature with fresh paste. I have never gotten a BSOD, only the monitor shuts off and the coolers on the graphics card spun at the maximum speed, then I restart the PC. Sometimes it just crashes the game and closes it, without the coolers spinning on the max. Guild Wars 2 game always tells me, after crashing, that there was an error with the graphics card driver. Other games just close themselves with no specific error message. The Windows error log always showed two errors: Kernel Power ID 41 and Whea-logger ID 18. I have never ran the 2060 on ultra settings in games. I saw no fix and I got the 3080. How common is this problem that I have had with my 2060? Anyone more knowledgeable than me to give any answer?
Had ro RMA my 2080 ti FEs (yes plural) 13 times total back then, Nvidia failed to properly repair the cards or I got them back with another issue. Dead Vram was a common problem with my cards.
Very informative video. I have a faulty 2080Ti (error 43) with a KO memory module detected by the "mats" program. I did a 6 min reflow with a heat gun on the memory but it's worse, the card no longer sends a video signal, the fans not working but it seems Windows starts up and I hear the drivers updating. Did the reflow cause a short circuit or break the RAM or something else ? I had put aluminum foil around the memory. My measurements : PLL connection (0,5Ω), PCI buffer(8Ω ), motherboard connection 12V (76Ω) & 3.3V (240Ω) ? Did the reflow cause a short circuit or break the RAM or something else ? Thks a lot
Noob question why does the memory being Micron from 2018 mean we have to replace all the chips? Is it soem imcompability betweene 2019 and 2018 modules?
Hey, since you're good at this, say, do you think that if i send my 6900xt to a generalist electronics guy, that he would be able to fix coil whine? he's good at general stuff and he has repaired game consoles for me before. i just want to know if it's something that's easy to fix and that one would know it. i mean, i'm inclined to use the superglue method for electronics illiterates such as myself that seems to works very well, but i'm not very comfortable with that one.
pretty sure my 2080 ti strix just had a memory failure, card still gets power and will passthrough video from the cpu, but windows disables the card saying it reported an error. also the picture that does still come through the gpu is artifacted with lines all over the screen.
I suspected it was failing memory on my Sapphire 280x it would have a square on squeen randomly like swap places with another square and parts of the textures would get mixed up/missing, and would commonly get horrible tearing issues with meshes. Also motherboard handshaking issues. It cleared up a bit after a oven bake (not proud of lol but it was that or it was dead) interesting to see and not as scary as I thought to replace memory now that I've gotten alot more experience soldering just haven't worked much with BGA
Hi there, great videos, keep on going, and i whant to ask you how do you test memories when they are off board? Ohms or diode mode but wich pins will tell that is bad memory, thanks...
Awesome video! So the take away is, avoid Micron chips with the 20 series. Something crypto miners kept annoyingly asking me whenever I sold off my GPUs, because they preferred Samsung. Now there's even more reason to avoid these memory chips, sheesh.
If you need a repair, please find contact info in the description.
When I saw the custom thermal pads I immediately thought it was user error. Lo and behold a plastic film left on the thermal pad. Wow!
I recently handled one of those pads for an SBC. The thin film is completely invisible to the naked eye, the only reason I didn't fall into this trap was that I remembered to check right before mounting the cooler.

I sort of had 2 of them in the last week usually when coming out of a game. Updated the drivers let's hope it's gone.

That's a BGA underfill and is not there because the solder is melting. The chips would stop working long before it ran hot enough to do that and holding it in place would only do so much anyway.
Underfill is meant to relieve stress on the BGA solder balls. Usually to minimize the effects of thermal expansion over time but Nvidia doesn't really care about that. It's only on the chips nearest the PCIE slot because they're the most prone to damage from board flex. I suspect it's also there as added protection for OEMs and prebuilts shipping these pre-installed in systems.
It's also likely part of the reason Nvidia has moved as many chips away from the slot as possible on the heavy 30 & 40 series cards.
@@JJFX- ok thats fair enough,i was thinking low temp solder 188 deg c,as i would imagine it would allow for a very small amount of thermal movement,under overclocking for instance,ive also had laptop system boards with resin around memory BGA's ,i wonder if it's the same reason. Do you think high end graphics cards are always going to have a high failure rate because of thermal stress,or is it something else? As for the small SMT tant caps,ive repalced a fair few of those, bit like the larger ones,they go short circuit as well. As the old saying goes,the cooler you keep components ,the longer they live.
@@enoz.j3506 Well this is almost certainly all lead-free solder which really melts well above 200C. Issues with the GPU itself tend to be on the large dies as thermal cycling has a more significant impact on the substrate joints over time. Different parts of the die heat up at different rates so the effect of thermal expansion become more significant. How the die is bonded to the substrate, the type of underfill combined with acceptable production tolerances have been difficult to get right while staying economical. This a big reason for the infamous Xbox 360 RLOD early on.
Hard to say how modern chips will hold up. Package engineering is very complicated and Nvidia has made plenty of mistakes in the past. However advancements in underfill and BGA assembly have come a long way since their more notorious issues. That said, they are dancing with the devil by using bigger and bigger dies pulling more and more power.
I definitely agree that those looking for longevity should keep everything as cool as possible. IMO, putting a full size water block on $1000+ GPUs capable of well over 350W is a no-brainer.
yes the thermal expansion in all dies is very difficult to control,if you think of the 28 billion transistors+ ,it is amazing it lasts as long as it does, yes i remember the xbox problems.
@@enoz.j3506 Yes it's pretty mind blowing. As processes get smaller and smaller it'll be interesting to see how the transistors themselves hold up. Interestingly, Nvidia's vcore target has largely stayed the same since Pascal despite going from TSMC 16nm to 5nm now.
This is like the Tech equivalent of those AMSR videos,🤫its just so enjoyable and relaxing to watch 😀
INCREDIBLE! loved it, i don't know any person who do that in my country, you have my respect 🙏
Bought a used Strix 2080Ti for $274 (incl. an installed Strix waterblock + the original OEM shroud/fan/heatsink assembly w/backplate). As I do not do water cooling, I removed the watercooler for resale and installed the air cooling assembly/backplate (after a deep clean, thermal-pad check, and re-paste). Unfortunately, the white shroud for the male FAN power connector to the GPU board was damaged (as-is) and although the pins make good contact, the shroud does not securely maintain the connection. Tie-wrap to the rescue. Done.
Now the card runs perfectly well. Benchmarked SAT. I then did an under-volt using MSI Afterburner...for safe measure. GPU runs cool and stable...very happy with a fine 2080Ti that cost me, NET, about $220.
wow...I am speechless at your genius level skills
6:20 how does one go about creating a linux usb with vram tests? I can't find anything on google about it
You're amazing, hope you get your money back for that hard work :)
It's interesting to watch your repairs. Wish you good luck. Some gpus repairs maybe won't pay back, but maybe some new experience you get push you bit further avoid any more same symptoms on bad/dead stuff.
It reminds me my old GF 8800GTX died after 2y heavy gaming long 10 years ago. I put it to service, was something like heat treated and UV too(Not rly sure), it worked again for another 6mo until it died again. That previous 20-25USD(500CZK) repair cost I didn't wish to repeat. That was time to get new gpu.
That silicon around the bottom memory chips is to protect them from coming loose/solder joints cracking from the sheer weight of the cooler that the GPU manufacturers started implementing quietly a couple of months into production.
Dumb question:
Assuming that the warranty is not voided with this kind of teardown, does the unpeeled plastic cover on the thermal pad at @6:53 constitute "faulty workmanship"?
It's likely voided.
can you explain more to depth about why 8 ohm on that coil means memory modules dead ? is it too little resistance ? too much ? there isn't supposed to be resistance maybe without coil ?
its all a big mystery for someone like me with basic understanding.
i love to watch your videos as its informative on about the issues that cards can have over time. great job on the fixing of the rtx 2080 ti!
I added a shit ton of additional pads to my 2080 when i got it after replacing the old ones and it still gets crazy hot on the back plane. Probably going to have to add heat sinks to the back shield with thermal adhesive.
wrong thickness=temps
nice. unlike the other youtuber, you talk soft, no rude and work clean.
This dude is an absolute Guru, why is your channel only 16k subs wtf lmao.....
Please start speaking about GPUS, PCB quality and such.....
Do you know if other GTX / RTX or even RX cards tend to have that same type of Micron vram chips?
Asking so I know what to look out for when purchasing used GPUs.
Browse through his older videos. He already did some repairs and mentioned it there. IIRC it´s related to 2018 manufactured Microns.
You will not find it out, tho. At least not without full GPU disassembly and thorough cleaning of the chips. GPU-Z does not offer this kind of info.
2000 series cards do.
You cant look without opening it up.
If its micron and starts with 8, get something else of problem will come sooner or later.
You done very good job. The question is how long it will last until break up again?
For mw B0 had write failures and sometimes it would be okay so i bought a rework station and reflowed it and its working for now.
Crazy it got resurrected from the grave. Alot of knowledge and skill here. Remember there was a big thing with this card about the memory having alot of problem. RTX 2080 Ti owner here and I haven't had a single issue thus far and I push the GPU to the absolute limit. Still, can't wait to eventually grab an RTX 4090 this upgrade
RTX 4090?
Are you puffing the magic smoke dude?
Sure. Struggle reading? Different type of memory were outfitted on the 2080 Ti depending on the purchase people could end up using a defunct version destined to be RMA or have severe longevity issue. Luckily I didn't get this particular chipset Micron or Hynix I got Samsung, but this could be an issue going forward. Not that would I expect you to comprehend this, drug addict.
Just get a 3070/3080
Not likely, the 4090 is nearly 2* stronger

I only know hardware, the programming is a foreign language to me. Funny seeing the opposite end of the spectrum. Lol
@@OCtheG same
your CS degree DIDN'T teach you basic hardware? what sort of CS degree is that? I had multiple modules dedicated to hardware. Of course the electronic engineers have more in depth knowledge, but we were expected to be able to design (i.e traces, component positions), fabricate (milling etc...) and assemble (surface mount inductors, caps, resistors etc...) a PCB and accompanying hardware, and program the MC on said PCB to control any accompanying hardware.
@@lewisd56 I am currently doing mathematics and computer science (UK joint degree) and I never got any hardware course, even compilers were exclusively taught to computer science people.
I've mostly just had theoretical stuff as compulsory courses and the rest to choose myself. And among the options we get, there's basically nothing hardware focused.
Still, I have been studying more on the side because I'm afraid of coming out useless from university even if I have pretty good grades.
@@leonro
UK computer science degrees too, (BSc and MSc), I had dedicated modules for embedded systems (C++ programming arduinos and other MCUs as well as designing accompanying circuitry), even had a module that went into specifics of logic gates and operations in a CPU. The MSc took a step back from the hardware, but I specifically picked the hardware oriented modules, so ended up working with more complex embedded systems and designing a whole PCB from scratch.
I've had the same 1060 for 6 years no issues besides when I replaced the thermal paste the original was like cement on the gpu.
I'm surprised how there are no class action cases for failing of 8 leading GDDR6 micron chip.
They lasted the warranty Period.
Wouldn't be surprised if Nvidia knew that and used them anyway so they can sell more Cards, given their usual scumbag behavior.
EVGA pulled out for a reason.
Dude Ur a genius
bro love your vids by the way
I've had two cards die since I bought mine in 2020.
First two cards were PALIT 2080ti Gaming Pros, both died due to issues with the GDDR6 memory - pretty serious problem from what I've heard from other 2080ti owners. Sucks even more that the RMA process takes around a month due to PALIT being in china.
Thankfully, they ran out of PALIT 2080ti Gaming Pros to send me last year due to the 3000 series coming out. 😂
They sent me a PALIT 2080ti Gaming Pro OC which is a card that costs £600 more than the £999 card I bought due to much higher quality components, thermal cooling additions and a much bulkier design for heat dicipitation. Haven't had the same problems with this card as the cheaper ones (touch wood), so I'm assuming it's due to thermal performance or the issue was fixed post-june 2021 (first two cards died within 4-6 months).
Repairmire:Diggie digi
good work partner
if i were near you would buy this art sadly we are far from each others
always watching your videos for learning something new keep it up my friend
It’s why I soak the plastic and let it rehydrate, then ram work better then new activating all the cells whenever and not just that teturns
So my 2080 ti its getting blue screen when i play some games or driver try to install, idk what it is, i need to investigate more.
Very nice video, keep a good work :)
When watching any of his video's you can see the results of a true technician not somebody that thinks they know what they are doing!
He has repaired a card for me with 100% excellent results, so if you have a card and were worried about his honesty or work ethics fear not he is the best !
Thats why I still used the good ol 1080ti thing is a tank.
Remember Micron from 2019? It has big troubles for 2080's as Hynix GDDR6 1gb modules for 3060ti. Yet appearing after years of service. Noone is safe from such things to happen, sadly.
It also depends on cooling too :p
4:58 every PBS show at the begining be like
Would it be possible for you the mention the price of the memory chips during the videos? Always interesting to know!
I think he just salvages them from other boards so it's not like they have a specific price
I don't think you'll get those GDDR6 Micron chips soo easily in the market. Nvidia and AMD makes specific orders which are then delivered by Micron.
i feel like a tech after watching
How often do you see instances of the plastic covering on thermal pads not being removed?
Good job team.
Thank you
4:47 whats the name of this software an where i can download the shematics ? greetings
Well, I guess it's beware if you're even buying something like a 2080TI in 2022 going into 2023. However, it would appear that you're doing those who would go that route a good service with this video.
Yeah... this video explains why there are now so many 2080ti's on the market (for cheap... like $200 cheap in case there are those not in the know.)
@northwestrepair could you explain to me how to find the gpu schematics showing the layout and values of each component like the one shown in this video?
Also how do you know exactly where to touch your voltage tester probes when looking for a short in memory, resistors, vrms ect..?
Would you be willing to do a video explaining how others like myself can get a beginners guide to checking for damage/ short circuits using a voltage tester to check for ourselves?
Any tips or advice would be greatly appreciated. I genuinely enjoy watching all your videos and each one inspires me to do some troubleshooting myself (I have a decent but still beginners level of experience with electronics) but i am to nervous to attempt anything more than a thermal pad/ repaste on any of my GPUs.
Nice Work!👍
I would buy it!
Sadly, i am come from Overseas....
I have an old Radeon 7xxx that I would donate. The fans turn on but it seems no signal over hdmi. I can't test the dp or dvi outputs.
with the resin on the bottom memory ic's... I think evga might have determined that the pcb flex near the pcie connector plus thermal cycles leads to those sm components breaking contact.
Makes me wonder how my 1070 is still chugging along with almost no issues. A motherboard swap when I upgraded from my r7 1700 to an r5 5600x got rid of intermittent snowflakes... Why? No idea.
This is why ebga has stopped producing GPU. I have a 1 year old 3060 ti sc gpu that I suspect memory has died. They sent me a replacement and not even a week after I have artifacts and cannot be reinstalled anymore. Pretty sad.
Very cool video. If I had the time, I'd like to experiment with component level repair, but I lack the necessary tools and shouldering abilities.
search a local shop in your area
Thank you soo very kindly for showing the music. Asher is amazing and its my new fave song!
micron memory chip since the beginning always have issues in 2080ti mine die like in 2 months of usage in 2018.I Remember telling EVGA to replace it for a Samsung memory chip don't want any Micron memory and since today still using my 2080ti with Samsung memory.
the micron ram in those 2080 TIs are basically like the 90nm RSXs in fat ps3s, they are timebombs, how can i look for 2080 TIs with samsung ram?
The glue on the memory chips near the PCI connector is there to keep them from detaching in case of excessive board flex?
That is for reflow soldering
where did you get the gpu schematic?
I thought he was going to talk about why it’s getting bad when it isn’t
clickbait
i took my 2070 super apart and the pads on the memory and vrm was fucked, 4 different kinds of pads, most of them not thick enough or too thick and also like a thermal puddy that was used ontop of thermal pads in a few places, and just too clarify this was a founders edition card, glad i took it apart before i really used it
You can tell which comments were made without even watching the video
That's what happens when you're a kid watching Linus Tech Tips. You replace the thermal pads for no good reason, improperly of course, and you also put liquid metal on the GPU for no good reason.
I bought my first thermal pads ever recently and even I knew that they come with plastic on both sides.

How do you get these diagrams? I'm new to this channel, I will spend some time looking through what you have available this weekend. I watched Rossman for years but I will never get into a situation to mess with apple products. This is way more along the lines of somethin I would love doing.
Nice video.
I recently had a problem with my 2060 where the first November update caused an issue and I could not solve it.
Important: I have never clocked my PC's components.
I have rolled the drivers back, reinstalled Windows 10 and tested multiple working components from another PC. When the graphics card was tested in another PC - it was the same issue.
It is weird, because I can either play for 3 days, 5 hours or 2 minutes. The problem was random and the temperatures were always normal.
I have stress-tested it and most of the time it pushes through the test with no issues.
I have even replaced the pads and the paste on the 2060. The original paste was almost rock solid.
But even with that - the card never exceeded 85° Celsius.
It still holds that temperature with fresh paste.
I have never gotten a BSOD, only the monitor shuts off and the coolers on the graphics card spun at the maximum speed, then I restart the PC.
Sometimes it just crashes the game and closes it, without the coolers spinning on the max.
Guild Wars 2 game always tells me, after crashing, that there was an error with the graphics card driver.
Other games just close themselves with no specific error message.
The Windows error log always showed two errors: Kernel Power ID 41 and Whea-logger ID 18.
I have never ran the 2060 on ultra settings in games.
I saw no fix and I got the 3080.
How common is this problem that I have had with my 2060?
Anyone more knowledgeable than me to give any answer?
i have a 2060 for 2 years and never got any issues, maybe you got unlucky ? i guess it was a good excuse to get a better gpu :p
@@Chaton_Mignon And a new PSU. :D
Very interesting and satisfying, how on Earth do you learn to solder like that, I can’t even solder 2 wires without problems 😅

Very informative video.
Had ro RMA my 2080 ti FEs (yes plural) 13 times total back then, Nvidia failed to properly repair the cards or I got them back with another issue.
Dead Vram was a common problem with my cards.
Very informative video. I have a faulty 2080Ti (error 43) with a KO memory module detected by the "mats" program. I did a 6 min reflow with a heat gun on the memory but it's worse, the card no longer sends a video signal, the fans not working but it seems Windows starts up and I hear the drivers updating. Did the reflow cause a short circuit or break the RAM or something else ? I had put aluminum foil around the memory. My measurements : PLL connection (0,5Ω), PCI buffer(8Ω ), motherboard connection 12V (76Ω) & 3.3V (240Ω) ? Did the reflow cause a short circuit or break the RAM or something else ? Thks a lot
Noob question why does the memory being Micron from 2018 mean we have to replace all the chips? Is it soem imcompability betweene 2019 and 2018 modules?
Because replacing one can cause adjacent chip to artifact.
Or it will artifact very soon after.
Hey, since you're good at this, say, do you think that if i send my 6900xt to a generalist electronics guy, that he would be able to fix coil whine? he's good at general stuff and he has repaired game consoles for me before. i just want to know if it's something that's easy to fix and that one would know it.
i mean, i'm inclined to use the superglue method for electronics illiterates such as myself that seems to works very well, but i'm not very comfortable with that one.
pretty sure my 2080 ti strix just had a memory failure, card still gets power and will passthrough video from the cpu, but windows disables the card saying it reported an error. also the picture that does still come through the gpu is artifacted with lines all over the screen.
I suspected it was failing memory on my Sapphire 280x it would have a square on squeen randomly like swap places with another square and parts of the textures would get mixed up/missing, and would commonly get horrible tearing issues with meshes. Also motherboard handshaking issues. It cleared up a bit after a oven bake (not proud of lol but it was that or it was dead) interesting to see and not as scary as I thought to replace memory now that I've gotten alot more experience soldering just haven't worked much with BGA
Hi there, great videos, keep on going, and i whant to ask you how do you test memories when they are off board? Ohms or diode mode but wich pins will tell that is bad memory, thanks...
Awesome video! So the take away is, avoid Micron chips with the 20 series. Something crypto miners kept annoyingly asking me whenever I sold off my GPUs, because they preferred Samsung. Now there's even more reason to avoid these memory chips, sheesh.
