Absolutely fantastic. In the late 1970s, I first worked as a repair tech on Moog and Arp synthesizers. It is heartwarming to see people still doing component-level repairs, even more so to see it done without unnecessarily replacing components. I have heard of reballing an IC but have never seen it done before. Tony, thank you.
You are very wise not to be trying to repair them today... a world of hurt. Especially after teh owner has "had a go at recapping it".
@@paulperry7091 i live for this
Oh hell yes! I'm an analog synth guy. You're so lucky, and probably got to meet Robert Moog too! I also do component repairs on my own gear. I'm a big fan of the youtube channel Mr. Carlson's Lab for techniques and inspiration.
@@Nathriel I did in fact meet Robert Moog. He made a presentation at the technical school I attended, and he was talking about the future: digitial synthesis.
Pretty cool!
My ASUS 4090 Strix low voltage light showed up, tried it in two rigs, still the same. I would have taken it back to Microcenter, but knew getting a 4090 replacement was about impossible. I thought I'd roll the dice and send it back into ASUS for repair, big mistake. They wanted to charge me 500 more dollars than the price of the gpu to fix it, 40 dollars for shipping, and 20 dollars for laborto fix it. No negotiation whatsover, called a customer serivice call center that didn't care for my plight or the repair cost, told me basically tough luck, finally contacted the ASUS US CEO, (Reddit research gave me the address) and they replaced my card, They said they fixed it, but sent me a replacement instead. It's working now so theres that. Nice to know that there are people out there fixing GPUS instead of rip off repair centers. (edit on price of repair update lol)
ASUS repair centers are blackholes.
I don't know how popular the long format videos are but I do know that they show us a slight portion of all the work and effort that you put into every card into every repair Tony. I hope you had a nice lunch or dinner after that 😊
It's not always about the video's length. It's more about if the video keeps your interest and attention during it - so that you don't worry about how long the video is.
@@johnpaulbacon8320 People are less likely to click on a 40min video than on a say 10min video. It's just a larger time investment and the algorithm knows that. It's pretty common knowledge that longer form videos get less attention on YT comparatively.
Edit: I personally totally agree with your statement. I just wanted to point out that longer form videos are less viable on YT generally.
@Bassalicious Hello. I know that. For me subject matter is more important then length. Length is next. Thanks for replying and keep up the good work.
@@Bassalicious They see less traffic but tend to perform better. Longer form video's tend to take a larger time commitment, absolutely agree, so those clicking them usually have an idea of the content and are more likely to both watch it through fully and also comment.
Shorts for discovery, mid length (the 8-20 min vids) to get people comming back and long form for better revenue and audience retention/engagement.
(long form kinda games the system, particularly for premium viewers revenue share)
One of those random TH-cam suggestions that pops-up and keeps me watching until the end! As someone who has done SMD work myself, I can say a very good job! Glad to see that there are stil component-level work being done by specialists in the throw-away society we live in!
Great video, thank you!
Hello i'm usually not writing comments but I've been watching your videos since you had 2k subs and I really enjoy ur Sorin's style but with GPUS :) .
Actually i'm really interested by your tools because i've seen that not only u are choosing good tools but also you have a lot of them that are homemade like the core lifter or the probe with the button to inject voltage only by pressing when we want and even your broom made or small wires that allows you to find traces on the board without the boardview. I would be really interesting if you do a video to introduce them all.
The 3090 has memory on both sides of the board. I fixed this by putting a heatsink and fan on the backplate. I used mine for mining, so I really had to manage those memory temps. In the end, the mining paid for the card and then some. Mine was not a FE, it was a Gigabyte and had a metal backplate.
my FE 3090 survived when i accidentally spilt tea all over my PC a few years ago. had to open it up and washed the pcb in dish soap, then dried it with isopropyl alcohol & replaced thermal pads; surprisingly it still worked even after accidentally knocking off a filter cap. this card has been an absolute champ for 3 years. the old skylake motherboard didn't survive however
You must think you’re cool using 666. I hope you know what that means.
Why would you pair a 3090 with a Skylake era CPU anyways, that would be the Thanos of bottlenecks lol
@@antonchigurh8343Maybe OP is planning to upgrade CPU but lack cash for MBD and CPU upgrade. Cash bottleneck is more common than PC bottleneck.
@@antonchigurh8343 from 2014 to 2020, cpu advancements weren't very progressive. was planning to upgrade eventually. ended up getting an i9 14900K after the old PC died and paired that with the 3090. the bottleneck for skylake wasn't too noticable
What do you mean CPU advancemens weren't very progressive at that time? Intel's biggest performance leap ever was from 7 to 8th gen when the number of cores increased by 50% from one gen to the other on the i7's
Nice repair as usual. I like the small pre-heater, a must for sure to avoid having to blast silly temps to a cold IC. I use my main pre-heater (same as yours, just still in one piece!). I place an aluminium plate on top and the IC goes there. The small one is convenient though.
I've never heard of a 3090 memory upgrade mod but I'm sure it's probably possible given it is on just about every other model. The strap configurations are likely similar to the other models that have been modded.
It is definitely a mod for the 2080Ti (22GB), 3070 (16GB) and 3080 (20GB). I think I have seen Chinese sellers even selling pre-modded 2080Ti's and 3070's.
if the 3070 & 3080 mods works well on games & stuffs oh boy! that's a very tempting attracting value cards right there!!!
but there are firmware cap though iirc, nvidia being nvidia as usual
why aren't the memories replaceable using the new JEDEC format, its ridiculous nvidia keeps capping memory and selling it so much more overpriced
I remember my PS3 came with a factory defect... They told me to send it in for a replacement... 17 years later im still waiting for that replacement.
I love your attention to detail. Excellent video. Thank you for posting.

Forget about the memory, would be a miracle if these pricks at nvidia had forgotten to make it impossible, somehow.
Easy in the 1990s, impossible now, mostly because of cooperate greed.
you speak nonsense, u can edit the memory for 3000 series, theres are 3070 with 12gb, 16gb, 3080 with 20 gb, 3080ti with 24gb... if someone finds in bios how to disable the back memory we can do it if it wasn't doing done already
@@Kiburici Yes, with 48GB and Quadro bios, it would be a Quadro RTX A6000.
Apparently, flashing GTX to Quadro with resistor modding or something wasn't impossible until not too long ago, GTX690 to K5000, I think, then Nvidia got greedy and decided to do some laser lobotomy, so RTX will never be a Quadro ever again.....
@@hinz1 you can still do it with RTX cards what are u speaking about
@@Kiburici 20 and 24GB 3080/3080Ti are actually made on 3090 PCB, you can't use 16Gbit GDDR6X on 3080/3080Ti core
I have old gpus with upgradable socketed memory
Very interesting video. Had a motherboard with a gpu on it that needed exactly this fix (gpu pulled and re-soldered). A common issue with this mb. Was able to heat gpu and got it working for a short while. ThX for sharing.
The bigger downside to halving the number of chips (the possibility to even do it due to firmware restrictions not withstanding) is the reduction of the bus width, in effect halving the advertised memory bandwidth. And those chips crave memory bandwidth.
no, because 3090 use clamshell configuration, the chip on the front and the back shares the same 32 bit bandwidth
totally awesome work there. it is always cool to watch someone like you work. get some food.
Enjoyed this video, I’m going to check my temps using the same method on my sapphire nitro plus 7800xt because I’ve spotted some inconsistent temps between hotspot and memory junction, I did very carefully check the tension on the retention plate 4 screws thingy and got about a millimeter worth of movement out of them, this made a difference of a few degrees on hotspot temps then I adjusted the fan curve to keep things in check, will now check those memory temps using gpuz and furmark and compare them to the hotspot 👍🏻
Tony, you are a GPU professor, full of knowledge, and you know how to teach and explain. To be clear, there are people who know, but they are not like you, you know how to explain and that is the most important thing. A genius professor specialized in GPU repairs, and probably many more. People like that made me fall in love with electronics.
I did not expect to spend nearly 40 minutes of my early morning watching a GPU repair video, but I was enthralled. Awesome stuff.
Nice work as always Tony. I'll post a link to a DIY re-balling station you may or may not have seen on your DC. In respect to the VRAM increase or 2GB modules on the fron...I'm intriqued myself. Great job and thanks.
Hey there. I recently subbed. Very good repairs and attention to detail. I am also doing BGA rework professionally, but i must admit, you achieve 5 star results with the basic tools you have(mad skillz). I would recommend that you look into tools like PDR infrared rework stations, Finetech rework stations, and you deffinitely need a Martin mini oven for those bga chips. Your attention to detail and determination is very motivating. All the best!
The 4004 CPU’s with 4K of memory I was repairing back in 79 weren’t quite this complicated. Switching in the paper tape boot loader on the front panel switches was the biggest pain.
20:08 is the time you are looking for
Oh no Tony's bringing the heat!
very detailed as always Tony, thx to You I have learned to repaire grafic cards and boards in general. Been asking in last few videos, what kind of new software for memory are You using ?
did not know about MSI's artifacting feature, thanks dude! I like to run these tests myself, just to make sure :D
If you are looking for reballing machines, have a look on the IR8500 (entry level) or a Honton R490/R690 (more “professional”). The IR is not that expensive, the Honton cost a bit more but might be worth for a person doing this for a living. Plenty of videos on youtube about both models. Hope that helps. Kind regards
another great job. if you can't fix no one else could.
Awesome! Thank you for Sharing! 💯✴
Great repair!!! I feel the struglem but that"s the way!!!
Nice video. I like your professionalism a lot.
Ahhh!! Another long format video! Much better! Better then that!! Your custom core lifter is baller
Dude. I want one. Lol. I saw at one point you tried an ir plate above. Hot air better distribution?
When trying to find where rubber thermal pads are NOT touching the heatsink, a piece of glass is a great tool.
You can see which ones touch the glass just by pressing it against against the board.
How does that help if boards have multiple levels?
@@juliusvalentinas use a small piece of glass, like a microscope slide
Thanks for the class time friend!
Measure the power consumption. If excessive, the unit is putting out more heat. Of course, good compression of thermal pads and good wetting of thermal paste is important as well. I work more with audio than computer, but it's not uncommon to have an OP amp drawing abnormally high current and running hot, even though it functions perfectly. You might even invest in a FLIR camera, that would let you single out the hot running chips.
i think they are all covered up while running so as they have one combined heatsink it would not be FLIR useful?
SPEEHLESS. Simply stunning ......
I used to own this GPU, I replaced the pads on memory, which fixed the memory heating up so much. I actually had memory junction temps of 110 degrees celsius! After replacing the pads the core even was able to go into thermal throttle rather than it throttling on memory.
You do this stuff couse you enjoy doin it, no rush.
LOVE the longer videos, people can skip around if they like shorter videos...
The quadro version of that gpu does indeed have 48 GB VRAM
Yes. The RTX A6000. The Quadro name was dropped. The RTX A40 has the same GA102 chip with slower GDDR6 and passive cooling.
@@Ranguvar13 make a ramdisk and run windows off that xD
nah rather use RAM as cache for ZFS@@SArthur221
Great job finding the fault. It was a bit surprising that you decided to fast-forward through the discovery of it though.
The small PCB of 3090 FE makes the memory temp situation even worse, throttling the GPU clock down the drain. This card begs for a water-block.
Brill repair, thanks for the info.
ive got a 3090 fe and ive repadded its gone down from 105 to around 86-90 depending on the case its sat in , this is as good as it gets for the 3090 FE. Also i came across something on the interwebs which states theres 2 revisions of the card and depending on which one it is depends on the thickness of the pads required. i used artic tp3's 1.5mm on mine and its been fine ever since :D
You probably have said before but what do you set the heat bed to and the overhead heat temp when removing and replacing the cpu? Thanks for your time and videos
Hello firts thank you gor squematics and show this defect in thr GPU NVIDIA nice day and greetings from Mexico
You make reballing look so easy.
Just for reference my 3090 FE, just like in this video, has the Memory running at 90c under load.
Thinking this was an issue on my 3090 I found that the memory, has a Max temp of 105c, before its an issue on the 3090.
This is the design that NVIDIA did with this generation, I believe due to the GDDR6x chips.
So seeing the 90c+ on this 3090 FE, is not a surprise to me.
If you want it lower, then its at best memory pads, replacement from the crap (white straw) pads that NVIDIA does at the factory.
My card ran fine, and did very well in Microsoft Flight Sim 2020, at max FPS.
Those crappy pads were the sole reason people started trying various thermal pads and even copper shim mods. Especially under backplate, where some individual GPUs had no pads at all (this was during covid, so there were possibly shortages or workers just "forgot" to add them)
The higher temp in 30 series is due to Nvidia using Samsung node if they were gone with tmsc it would have been lower
Just because they say those temps are within spec doest mean it's safe for longevity of the card life/board its attched too including excess heat on the core from behind. I would always advise to watercool the card on front an back plate for 3090 and 4090 series gpu just because of memory chip temps are way too high with any stock cooler on for my liking ,since watercooling my temps on memory under load are maxed at 39 after long periods at full load
On the 3090s the mem temp being so high is due to half the chips being on the back side of the pcb. Almost no cooling. The sensors will always report the highest temp of all.
10:18 you can add a 3d printed impeller and diverter to your output to achieve the spread of hot air. A changeable diffuser nozzle would allow for directed heat versus diffused heat for specific applications.
Great Details-Thanks
As long as you're there, a few strips of soft copper on those mem chips could fill the gap and conduct better than extra thermal tape ?
nah this dude its a next level fixing god
A few levels above the "NO FIX" guy...
@@Nordic-sm3urthat "no-fix" guy does not fix only replace. 😂😂😂
@@fixeuskeane ...and occasionally blow up customer hardware by injecting 3V into a laptops CPU and charging the customer a fee for him destroying it live on stream, then going on a banning spree for anyone pointing that out 🤡
To change the memory sizes on the GPU, you must have access to a schematic from the board (not public available) and be able to reconfigure the jumpers on the board (0 ohms resistors or not, I saw previous models worked by percentages in drop voltages) and may be some cases changing the memory space inside the GPU bios.
I really like your videos, i can relax while watching and learn something i'm never gonna use in my life lol. What was the problem at 20:06? one of the circles was grey, while the other ones where silver? was there a contact point coated or something?
I love all the 3D printed gadgets you have :D what do you use the PWM for?
Amazing Work Again 👏
Good video, Nvidia's quality control is great as we can see.
nvidia is a giant defect in general
AMD PEASANT BURGER FLIPPER BUDGET GAMER STRAIGHT FROM THE BASEMENT DETECTED!!!
Yeah I beg to differ. I have had MANY different Nvidia RTX cards. And I have not had a single issue with any of them. Including the 3080 and 3090. I have had a 2060, a 2070, a 3050, 3070, 3080, and a 3090 and had zero issues over the years. And these are cards I have found off Facebook marketplace on top of that. I like AMD as I have some AMD cards as well. The only problem I have with AMD is that I don't know if it's the drivers or software that's not optimized properly but it does not get along with some games or editing software. Nvidia just does it right.
I mined with my 3090 Fe (in a waterblock) 24 hours every day for a year, and now I've been gaming on it ever since. It still works lovely.
I do have Fujipoly pads in it. My Vram tops at 53c while gaming.
@@cesaru3619you are retarded
Speaking from experience, the completely working gpus you get sent will likely trace back to a failed PCI-X socket. Had one of those in the other day. These stupid cards or the MB/case's they put them in put too much stress on the slots, and the slots fail.
When we check piston to valve clearance in an engine we use plasticine and measure how much it squashes, I guess you could glue down little balls of alum foil and measure the height after a dummy fit.
plastic gauge is far more commonly used for good reason no? It won't scratch or damage.
@@AppriIt's more for the even squishing properties. Things that would scratch or damage would not squish so well.
@@MSFSFreeware Both true I suppose lmao
@@AppriI also love the way they talk about measuring the height, rather than the squish width lol - I can see those aluminium balls not squishing and causing some snappage also !
It's crazy to think that this wouldn't be covered under Warranty where you are.
Here in Australia I think government demands 3-5yr for computer electronics.
Use to deal with a lot of these grey pads (dry solder joint) back in PS3/XBOX360 days.
This level of repair is rarely worth it unless device is REALLY expensive.
Why are you reballing? The issue is most likely between the die and BGA package, not the package and the PCB. The thermal stress from reballing might solve the problem temporarily, but you're charging the customer for a fix that probably won't last.
you can change memory chips on nivida i assume since someone did do something similar by increasing the memory cap on a 40 series card manually.
3090 memory getting super hot is so common, passive backplate was never really enough cooling. When I had a founder's edition 3090, I put a waterblock on each side and that's what it took to get decent memory temps.
i got rid of my 3090 because of the memory heat
replace the awful stock thermal pads with 1.5mm Thermalright pads - MJT rarely goes above 100c
any 3000 series with GDDR6X run that hot. I have 3080 FE similar memory temps when maxed out.
Im selling my 3090 and went back to my old 1080ti or who is my "ole reliable" power draw and heat on the 1080ti was great. Hoping battlemage is on par with the 3080 or so with less issues in regards to heat and power draw.
I have a question, from your experience repairing gpus, which of the mainstream brands make the best gpu in terms of the quality of the materials and parts like pcb and its construction? Thanks
It's just so amazing to me. The simplicity of it all, but how say a piece of foam makes makes all the difference in the world. I didn't realize the alignment of a heat sink was that important.
One problem with some of these boards is that they really need a brace or to be run vertical due to weight. I've seen many GPU boards that have a suspicious amount of flex in them when installed. One old card of mine you could see light between the pad in a couple of places as it had simply pulled away too far.. My son's computer was remedied by putting in a long zip-tie to the chassis to relieve some of the excess weight.
Even though they don't seem to likely cause any contact where it shouldn't occur, when you switch off the little hearing plate there still seem to be little traces of solder paste inbetween the points the should be at, almost looking like dendrites (14:44, left corner, a bit earlier also right corner)
Have you tried furmark 2? Seems pretty good from my usage
I redid all the pads on my 4 4080s. I can not remember the sizes but you can find them on many crypto mining sites. The new pads made a huge difference in memory temps for me. like 15-20 degrees under full load.
How many gigabyte 4070ti GV-N407TAERO OCV1 issues have you had come in? curious since im an owner, and sold my 3070ti FTW3 the other day. i do have a bracket on the car to hold it up. Still, makes one curious when ive seen so many cracks, and cooling issues from V1 of this card. (650 bucks) new so i couldn pass it up.
Since 3000 series the memory temps are a joke.
In like 5 years we will possibly see a lot of them actually die from silicon ageing.
hello, im searching a kind of study to make the same job as you. Do you have recomendation ? Exept 5 year of ingenior, there is simple formation. What kind off study you recommand. Thanks
3090's memory temps are always insanely high when in use. they can even go up to 100c bcs there is no active cooling on the back of the card, where the other memory modules are
Woo hoo another video!
You can buy Achi up IR heater. Pretty good solutions.
Great video! You mentioned the Founders Edition 3090 is the worst. Which are the best?
When you are constantly trying to make things cheaper stuff like this is bound to happen. Like the pads that are about as thick as a piece of tissue paper in the name of saving a few pennies on copper. They clearly are designed more for one time soldering than repairability but the fact that they are pulling off the boards merely from uneven mounting pressure shows they are not even sufficient for that.
Wow, it's like they made a special "rub off here for no returns" pad! ;)
One of the rare occasions I purchased an extended warranty
Hello great video absolute wizardry what temps do you use to remove a core?
Depends
Why is it running at 1350mhz? That's a fail safe clock speed
9:50 "Why am I wiggeling this thing around? I don't know." Heard enough.
The amount of work you put into it is worth more than the card probably
Was this a badly tinned pad that worked just enough to pass factory tests but break when put to use?
GPU seems to be clocking a lot lower at the end of the video after the card has been fixed. Could this have any impact on the error appearing or not appearing?
my guy is playing battlefield 1, you got my like
Have tried use a straight edge a lets say a 1 to 2 " long flat piece on top of the CPU and then check what are the gaps or height differences in relation to CPU ?
It's possible the tightening sequence was done incorrectly around the core, tightening one side first, then the other leaving it on with uneven pressure.
Great job .... awesome :)
hi, I really admire your videos, I watch them all... I wanted to ask you if you could create a video where you show how you adjust the temperature of the station you built, that is, what times you respect, how many degrees, how long to desolder and heat the graphic chip of video cards without breaking them. with some advice and I hope for your video on this topic thanks
On memory arrangement change it depends entirely on the GPU.
In many GPUs all the memory chips are arranged in parallel to increase the bus width. In this case you can't.
However, if you have two chips per a channel instead of one, you MIGHT be able to, depending on the pinning of the chip type and the ability of the board firmware to recognize the new arrangement.
A FrankenGPU with workstation memory but a gaming card core is not possible because workstation card memory is typically parity memory and thus uses and extra bit line to ensure data integrity, at the expense of a tendency for slightly higher latencies.
As a note, you CAN upgrade the RAM in many smart devices, although most require you to mod the firmware to recognize it.
Yeah, this is why I buy branded known to be good graphics cards as opposed to those made by NVidia themselves. A lot of the "issues" of framerate differences can be contributed to cost cutting factory practices at the expense of quality control.
I know in the old days when you used to overclock video memory you would get artifacting because the transistors would be overloaded. So yeah I would suspect VRAM.
Looks great, I have a 1060 GTX card that is acting up in a similar way. Normal 2D works fine, but if you run a 3D-intensive game, like the System Shock Remake for about 15 minutes or so, the whole system hangs. It's not a driver issue, because the fault experienced is exactly the same whether I run Linux or Windows.
I've seen a GPU case where it would 100% pass furmark with zero artifacts or crashes but random polygons would disappear in games, it was annoying AF.
All memory was OK. I traced the anomaly to vCore fluctuating like crazy. Unfortunately the card died with a probe slip before I could fix it or even determine if it was defective core or vrm.
vrm controller swap didn't help.
This may be dumb but i have always wondered this. What are the gold pins at the top of the board for? Not the regular pcie slot gold pins but the ones on the other side, at the top of the card when its on the preheating station. Im slightly tech savy and learning new things daily so i was just wondering.
Oh wait is that for sli? I thought that was obsolete.
@@danielhulan3058It is obsolete but yeah was still included on 20 and 30 series despite it not being useful for any games any more, technically it is called NVLink. I guess it still had workstation applications?
@@danielhulan3058Nvidia calls it NV-link now, but still possible on xx80 and xx90 cards
