I love watching your videos! You are an old school craftsman reviving GPUs for us sweaty. Mountain Dew drinking gamers who have been scorned by the RMA gods! I obviously never want my 4090 to die but if it does, I'm requesting your services. I was in a car accident that left me paralyzed from the sternum down. It affects my finger dexterity to the point where I could never work with my hands. Had that not happened, you probably would have inspired me to do this kind of work. At least in a hobbyist capacity! Keep up the good work and good luck with future 5090 repairs! As soon as i saw the founders edition board design, i thought of how techs like you will tackle it. Should make for a great video.
For those who ever wondered why a high side shorted mosfet on memory kills the core but a shorted high side on vcore doesn't (at least most of the time) is because of the resistance of those lines in respect to the resistance of the shorted component. The resistance of a shorted mosfet is usually something around 0.8 (that's very specific and can vary, i know) or more, since the resistance on vcore is usually lower than that, the shorted mosfet "takes" most of the voltage drop on that line, that means the core itself doesn't "see" 12v, but a lower voltage. But on memory you have a way higher resistance than vcore and usually higher than the resistance of the shorted mosfet, in that case it means the components on the memory rail will actually "see" a higher voltage than shorted mosfet cause they have a higher resistance and therefore killing everything in there, memory chips and the controller inside the core.
Yep, I have repaired a GTX 970 back then that keeps shorting the high side fet from a vcore phase, and it happened 3times, the card still works fine After 2years right now, it's from my friend, it only stopped shorting the high side when I also replace the 2 low side cause I'm out of options that time, even replaced the mosfets driver twice. The 2high sides works fine when I tested them multimeters it still a mystery to me why its causing the high side to fail
Everyone makes mistakes once in a while. Glad its not a brain surgery lol Also, the card is dead anyways so further adjustments won't make any difference.
Yeah "the other guy" will just take your money by glancing at your card, saying its a no fix (because it would actually mean. He has to work) call it a no fix and charge you a bench fee. His business model rewards him for just saying your cards a no fix and moving on.
Hey Great work as always, but just a side note Not doubting your experience as mine is super limited, but I had an artifacting 3050 a month ago, and I tested it instantly without checking resistances, it worked and showed artifacts as described. After disassembling it, checked the resistance on the memory rail and it was 0.3 Ohms. Turned out 3 out of 4 hynix chips are short, replaced all 4 and it works. Not sure if it's worth it in your case to check or not, but yea, weird stuff happens sometimes
Может шорт с памяти не ушел, потому что на 9:32 слишком много лишнего припоя, который соединяет несколько выводов повер стейджа с конденсатором/резистором?:)
How hard is it to take off the core and check for the short directly? Seems like it would only take a few minutes. Seems like if you're right there's no harm and if you're wrong, then you learned something. Could it have been that solder blob at 9:30?
Ofcourse they are cheaper, they skimp on the looks, they do not have any accessories, no box, no warranty and you can get them only in used or refurb condition.
amazing video keep it up! where do i get new memory for my zotac 3060 ti the memory i have is hynix memory and im afraid that it is going to artifact soon.
component failure- that black chip he was grinding failed and shorted out the entire card, sending voltage in to everywhere it shouldnt be. bye bye GPU. sometimes components simply fail
try undervolt or framerate limit, also get case with noise isolation or buy materials and make your own, or simply place pc under desk, there is no magical fix for this issue unfortunately
@@Takashita_Sukakoki yes, they usually add a blob of epoxi or some type of putty on top of the coils to prevent it from vibrating. it is normal practice on power supplies.
That shunt acted as a fuse but u need a tremendous amount of current to blow a shunt, and I won't blow in an instant it will take some seconds. And by that time the mem controller and the memory were gettin toasted by the 12v rail
So, you do charge for repair attempts now? Note, I have zero issue with this if you do and think you should with all the work and time you put in on even cards that look like they have little hope.
If one of the mosfets is not good quality enough it will fail. If one of the mosfets is not cooled down properly, it will fail. If the power management chip starts to send bad signal to one of the mosfets, the mosfet will fail. If one of the capacitors in certain positions are failing, the corresponding mosfet will fail. Yes, replacing the shunt with a fuse may help. It's not 100 percent guaranteed to protect the card but most of the times it does.
Whats wrong with pink? For a longer time then is remembered baby-boys had pink clothing and girls had light blue clothing... (pink for red == blood, warrior, light blue == purity, innocence). So, don't worry about colors :)
almost all the DrMos repairs are from this brand. gotta be a red flag seeing this alpha omega ics. Looks 5090 is exclusively MPS at least. you could still get 4090 with these stuff.
I AGREE. But if you think about it, if it didn't come with fuses, do you think there would be pads in place for them? I know you can mod it to add fuses, and THAT would be an awesome instructional video to see!!
@BlueStraza that's why we need a video given we will have to remove the shunt relocate the current sense traces and add fuses I have done it on my old gtx970 but I would still love to see a video from a professional Kris fix Germany also made a video on it but I never found it again
Still waiting for tony to care about something
lol

You must have already given up on "Alex" then? LMAO. 😂

But he doesn’t care 🤷♂️😂 I don’t care either, do you care? 😅😂
Having watched big Clive, i can say that pink electronics are the most exciting
I don't like to like videos when youtubers ask to do so.
Therefore I always like your videos before I watch them.
Sometimes you win, sometimes you do not. Thank you for always showing the unrepairable "patients" as well. Cheers!

8:13 I dare you to use milk next time :D
Also I bet all new cards are lactose intolerant and need vegan nut gluten free milk :D
Hello Content Creator
Just wanted to say hi again.
The old blind geezer from the other side of the pond.
There was a solder blob left betwen the Mosfet and the Cap that you had to reposition.
@northwestrepair
9:31, yeah could be
@northwestrepair
Yeah, I saw that too
Everyone makes mistakes once in a while. Glad its not a brain surgery lol Also, the card is dead anyways so further adjustments won't make any difference.
If I ever need a GPU repaired, I'm sending it in to Northwest repair, not that other channel, that talks down to his viewers.
The "non repair" in the other guy will be faster...😂.

Muchas gracias Tony ❤ great video.
I swear there was a solder blob left behind on that driver mosfet repair
Also did see it.
😮

On TH-cam, you are supposed to show only your wins! LOL. Thanks for the video showing the real world.
The G.O.A.T !!!
Tony there’s a solder blob around the mosfet you replaced that’s shorting the memory.
Tony, for real, will you ever do a live stream fix? Id love to see a live fix.
0:05 Hello darkness, my old friend 😁
I think your old grinder can also reverse direction if you keep the button press
I see tony. I like video. Simple situation we have here
How hard is it to take off the core and check for the short directly? Seems like it would only take a few minutes. Seems like if you're right there's no harm and if you're wrong, then you learned something.
Could it have been that solder blob at 9:30?
Hi! What is your thermal camera thing? I wish to do DIY repair on my dad's tools and that thermal camera would help a lot to have one :)
infiray
Infiray has rebranded to xinfrared, and I think their T2S+ model is fantastic for SMD work. It has a zoomable lens that makes it very versatile
😮
7:20 Any brand or model number of that new grinder?
Thanks for a video.😁
What is causing the short on memory that you could not proceed with the repair?
the short is in the gpu core
@@olDirdey but cant that just be fixed with a reball of the core?
😮
Hello nameless, I'm Vader, Darth Vader from the darkness.
Do OEM cards go for cheaper than their AIB partner counterparts?
Ofcourse they are cheaper, they skimp on the looks, they do not have any accessories, no box, no warranty and you can get them only in used or refurb condition.
😮
I like how the OEM cards look.
amazing video keep it up! where do i get new memory for my zotac 3060 ti the memory i have is hynix memory and im afraid that it is going to artifact soon.
What causes shorts or dead vram memory?! High temperature and what else
component failure- that black chip he was grinding failed and shorted out the entire card, sending voltage in to everywhere it shouldnt be. bye bye GPU. sometimes components simply fail
@@MrPuddinJonesSounds like an apple mackbook failure.
usually high temps and oxidation.

Толь, немного проспал выходы твоих видео. Расскажи про ручные шлифмашинки плз. Это что то из ювелирной сферы?
Did you find your micro lens Tony? Thats good. Ir did you order a new one.
No I got a whole camera from Amazon. I'll return it when replacement arrives.
Do you fix coil whine by chance?
i would worry if whine would stop.
try undervolt or framerate limit, also get case with noise isolation or buy materials and make your own, or simply place pc under desk, there is no magical fix for this issue unfortunately
@@northwestrepair Coil whine is an interesting beast is there even a practical/physical fix?
@@Takashita_Sukakoki yes, they usually add a blob of epoxi or some type of putty on top of the coils to prevent it from vibrating. it is normal practice on power supplies.
@ but doesnt really exclude even psu´s having coil whine but how do you remove it? Change coils?
how many cards do you do a day? Seems like every day you have time to record, edit and upload at least one video
Green PCB, classic Dell
Will you still make the edited videos with the great music? Thank you.
i have the same model
im in danger?
Dell💀
That shunt acted as a fuse but u need a tremendous amount of current to blow a shunt, and I won't blow in an instant it will take some seconds. And by that time the mem controller and the memory were gettin toasted by the 12v rail
new skill learned, lazy readings (without dissassemble) hahahahahaha i will start to do that more often. There are some boards that we can do it 100%
So, you do charge for repair attempts now? Note, I have zero issue with this if you do and think you should with all the work and time you put in on even cards that look like they have little hope.
Oh, we have short on 5, hehehe😂
How much is the attempt price tho
How and why happened short?! i want avoid it cuz i have same GPU
Maybe the shunt mod destroyed a driver MOSFET
overheating, need to replace pads like every two years on hotter gpus.
Replace that shunt with a 5-10 amps fuse. its a 0.001 ohm so i doubt its used to check power consumption.
If one of the mosfets is not good quality enough it will fail. If one of the mosfets is not cooled down properly, it will fail. If the power management chip starts to send bad signal to one of the mosfets, the mosfet will fail. If one of the capacitors in certain positions are failing, the corresponding mosfet will fail. Yes, replacing the shunt with a fuse may help. It's not 100 percent guaranteed to protect the card but most of the times it does.
😢
Why did tony deemed the whole card unfixable? Were all the memory chips dead or the core itself? Would like to have better explained
Pink increases grinding 😂
you can grind the opposite direction by holding the grinder in your other hand
yeah but you have to be leftist
@@northwestrepair😂😂😂😂😂😂😂😂😂😂😂😂😂😂😊
😮
no win because of pink grinder ;-) what is your success ratio Tony, btw?
Dell?
or HP. same thing
@northwestrepair No. It's a Dell. They're both "fugly" though.
Can You give a link for these probes :D ??
Yes, I can in fact read :P

You're the one bringing gender into this. Pink is simply not a professional colour, the same as lime green and baby blue.
yes that is what tony does. he is bleeding in a war.
that pen is also used by people who work with acrylic fingernails I believe.

No shunt mod
Losing stuff thats an arms length. Special like me 👍 lol

Just don't buy Dell 3080 & do shunt mods & you wont have a dead card.
that's enough internet for you

It's PINK! and you're always playing with re-balls.... just sayin. ;)

another day of asking you to make a video of how to install fuses on a gpu which don't have it from factory
I AGREE. But if you think about it, if it didn't come with fuses, do you think there would be pads in place for them? I know you can mod it to add fuses, and THAT would be an awesome instructional video to see!!
