Nice attempt, unfortunately these kind of diy repairs are very much dependent on the exact temperate, distance, airflow and time applied. Sometimes a few millimeters of distance, degrees, or seconds can mean success or a total failure as in burnt. Another issue is that after the "repair" under normal operating conditions the joints can become debounded again usually due to the heat generated by the graphics chip. Nonetheless, it's worth a shot. :)
Thank you. I'm typing from my resurrected computer :) Machine was crashing every ~30 mins to 1 hour for about a month until finally it showed artifacts on the screen during bootup process and would freeze before getting into Windows. I used a Porter Cable brand 1,500W heatgun with the temperature dial at around 85-90% power for 3 mins and 45 seconds. I see you only did yours for 1 minute but my chip is about 4 times bigger (Sapphire Radeon HD 7970 Dual-X). I also watched a 2nd video on this process which is how I gauged where to set the temperature dial (also - they did 5 minutes, but I decided to do only 4 because if it didn't work I could always go back and try again). Best of luck to everyone attempting this.
Great great video my friend! Simple and very good example of "Reflowing" from start to finish! I've spent HOURS looking for this EXACT process being demonstrated in practice / as well as before & after examples of the electronic itself and the effects of the reflow! Tyvm for this wonderful example my friend! Maybe add "Reflow" in the title and add a Reflow tag so it can be referenced because you seriously have the best example here that I have seen on TH-cam and it could help even more people than you already have. Thanks again :)!
My mid 2011 iMac (27") stopped working completely after the graphics being all weird for a short while. I used that video to check the appropriate temperature and how long the heat should be applied. After un-mounting my iMac to remove the graphics card (which was hell), I did about 200℃ (looking at the indicator on the heat gun) for about 50 sec as in the video. It worked the first time. This saved my buying a new card (about 2万円) or Apple telling me to buy a new iMac instead. Only those old iMac can be used as a secondary screen for a Mac laptop which are so useful during COVID. Thanks man! You deserve my upvote!
Nice video and good job on the card! I have done similar repairs in the past, mainly on Xbox 360s because of the whole RROD. I also thought you may have applied heat for a little too long but if it works! Don't think it matters too much really, anyway. The only problem with these repairs is that, I find, they don't seem to last too long and the problem reappears weeks/months down the line... Another thing I think is fairly important, is that the board needs to be kept very still throughout the whole process and for at least half an hour afterwards. I couldn't tell if you did this because of the way it was edited but I just hoped you had, at the end of the day you got it working, though, so great!
+Oliver Huckstep thank you! The card still works for the moment, but as you say, sadly it's not a definitive fix in most cases. I don't remember how long I left the card unmoved, but it might be for less than what you said, so I will do that in future repairs for sure.
OMG.....The HP TouchSmart 300 screen turned on....i heated the small gpu chip (next to the cpu) for 30 seconds. I replaced the power supply and was about to buy a new motherboard. THE VIDEO CAME BACK ON, WOW!!! This really does work man!
Not that good of an idea. 1. Solder on the chip? seriously? what if u short something like that? 2. Solder ON the chip will melt MUCH FASTER than solder UNDER the chip. Bad idea to "measure" this. What he did in the first place was ok. Just a bit longer and than test if it worked.
A common fault >>> Caused by Video Card Sag. The Sagging happens over time with gravity and a low heat generated by the electronic processes running the card. This also happens with machines that run continuously ie: 24/7 without being used. The video card in a Tower is not vertical > this sagging happens over a long period. This is not common in Small form Factor Machines at all. The evidence points to 'Solder dry out' and softening by heat of the video circuit board and influenced by gravity, culminating in bending.
Sagging is a result of the gpu card tabs being much smaller than the slots they fit into on the case behind the motherboard thus they drop and appear as sagging.. Nylon screw or toothpicks in the slot where the tab goes after card is installed will fix it (Just hold card level and use non conductive piece in the slot to keep it there Nylon screw works best). Too many myths not enough new designs.
Youre a life saver!!!! Thank you so much! Didnt really have a heat gun used a soldering gun and inverted the gpu like cooking it and it worked. It fixed my gpu which had no signal.
You can put foil over the surrounding components to keep the plastic from melting and protect them generally a little bit. I put a D630 with the notorious nvidia card in the *oven* and it worked for a little while. I'm viewing this video because I have an older Dell monitor that I bought cheap because it occasionally blinks and has artifacts. Lived with it for 2 years but I'm thinking it's time to try a reflow. Only thing is I don't just open a spacious case and unscrew it.
I have a dead card that I suspect needs a re-flow, and I say that with some confidence, because it gradually got worse and worse. I was thinking about using an oven to bake the card, because people have been suggesting that recently on the internet. However, by heating only the chip, there's less chance of creating new faults on other components. The chip shouldn't take any damage from such treatment. I think I have to consider a heat gun instead, and yeah, they are cheaper too. Thanks for showing your success and make me re-think this!
@@UltimateDIY Well, it seemed to work! I just hope it lasts. I gently warmed the whole board a bit first to reduce any stress in the material, then I covered off the other components with a bit of aluminum foil like some others on TH-cam have done. Like you, I tried to gradually heat it up and gradually cool it down. It's hard to judge the temperature and time since the heat need to go through the whole thing, but a couple minutes of heating up and then about 4 minutes of the most intense heat period seemed to do the trick for me, with a little bit of motion to spread the heat. Older cards probably take less time to heat up. The gun I got has two settings, and I used the lowest one which is 300 degrees Celsius, which is well above the melting point of the solder, and lower fan speed. Good luck to others that want to try this!
Many say that this is not a good fix and it should not be done. But in my opinion, it's worth reviving a bad card even for a few months in the worst case.
I just managed to fix a Sapphire r9 280x with a heatgun. The card produced artifacts and went black during boot. I disassembled the card, cleaned it with alcohol and covered the circuit around the GPU with aluminium foil. Then I used a cheap 2kW heatgun for approx 30 sec directly on the GPU, with a distance of ~3 cm and moving in circles. After I let it cool I added a new coolant paste and reassembled it, and now it works!
I’m glad to inform that two of my graphic cards are working again! Thank U! In details: I have Nvidia 8800GT (artifacts on the screen to the point that just after loading OS it freezes) and Radeon HD5770 (couldn’t even start the computer - black screen). I used exactly the same heat gun with 350°C settings only and for about 2.30 - 2.40 seconds. When finished I left both of them for 30 minutes to cool down and assembled again. That’s all :) Cheers!
Great video. Just as far as I am aware reflowing should also be consisting of letting a nice amount of soldering flux under the GPU chip to remove all oxides. Also this isn't most durable fix for GPUs according to most people that work on this. Just a heads up :) Great video anyway. Really educational
Dunno why some ppl are spreading all this serious HATE! If it's your own card, and you will otherwise throw it away, what do you lose by trying it? DIY re-balling is MUCH more difficult, so best left to techs with experience - and that's gonna cost you plenty..
My card was dead, starting with artefacts, 24h latter black screan, nothing. Card was on my shelf last six months, i found heat gun today, it worked. Im typing from dead GPU...hahahah, hope will last some time, will see. I baked only GPU with heat gun for 30 sec. at 550c (heat gun spec), i used metal foil to reflect unwanted heat from other parts. I did not use flux i will do some testing and report if somebody is interested, Cheers
This is a temporary "fix". The issue is the bumps that adhere the die to the substrate and not the solder balls between the board and the GPU. Heating the chip causes these bumps to make contact again. After some heating and cooling cycles the bump(s) will break again. This is usually after 30-90 days
After watching a few videos on this subject, that is also the conclusion that I reached in the end. The weird thing is that the GPU in my video is still working.
Ultimate DIY it really depends. Some may last for a good while and some won't. It depends on what part of the chip fails too. I mainly do motherboard repair for MacBooks... Check out my channel if you'd like
Other video that I've seen stick Kapton tape to the heart of the big chips. Also they apply flux wherever they could so they can see it it's melting. Flux also remove oxide from the old solder making them reflow more readily
"this is bloody working" great comment,! going to try this on a lcd tv main board. have mounted a CPU computer fan over the board and i no longer get my problem. normally the problem appears once the board is hot so i am thinking a bad solder joint. good video!
So if you have decided to reflow a pc card then do it a little more efficient and professional.Use a flux paste like RMA223 that is somehow liquid to flow underneath the bga,use your electrical home barbeque grill for bottom preheating and for upper heat the same heat gun until the solder balls to melt and with the lightest poking the bga looks like floating on the solder balls.Floating the bga is the evidence that all the solder under the chip has melt and the chip resolders in its place.Greetings.
I was getting alot of artifacts & screen going off and on using a 5 yr old 560 ti I tried this but I pasted some reflux on all the sides of the processor & hovered the nozzle of the heatgun in a circling motion blasted it for a minute. Works like a charm no more artifacts & blinks thanks man I was ready to give up on my 560 ti I have money ready just incase it does not work I'll go ahead & buy a new 1 very nice so far I'm playing dota 2 on it for 2 hrs straight no issues will update you guys if something comes up.
@@UltimateDIY Well, it kinda worked on mine lol just dont move the screen hinges much, or else a big line shoots through middle of screen! Yeah looks like time for new chip, or new computer... nahhh it works good enough for me haha better than no screen!
Is it still working? Any new video about the card working? I would add a few drops of flux under that chip, preheating the chip and not putting too close the nose and covering the other components with alluminium foil.
Ok good. I do have some gfx cards with almost same problem. It is kinda of annoying... Gfx cards should have sockets where we could put gfx chips like in the older days where socket pins were tightly with the pcb.
Well i got myself a heat gun recently and 100cc of flux and so far i fixed 3 gfx cards, im using one right now named geforce 8500 gt and it is running on windows 10 pro. and there is one 12cm fan with magnet installed vertically blowing air to the gfx and to the motherboard. so far so good. this 8500gt does really get too hot without any airflow. 80c with just the cooler,
Fixed GTX 580 artifacting by just heating up the concerned GDDR5 module. You can identify the problematic VRAM module using the MODS/MATS software. Heating up the core risks damaging it permanently.
@@DarkoPetreski not entirely true. In my experience repairing PS3's the NEC/Tokin caps are the problem *maybe* as high as 15% of the time. One reason people thought the Tokin's were the problem most of the time was because the heat required to remove and reinstall the capacitors had an unintended side effect of temporarily reflowing the RSX (since they are so close)
Funny enough, I came here to see if I could fix my own GPU from an old Core 2 Duo machine, it's a 7300 LE lol Going to attempt this repair, hope it work. Thanks in advance for this video!
@@illiakolosey4285 No, unfortunately not. I must've tried a dozen times and I was actually noticing some differences sometimes but was never able to get it back 100% to working state. As a last resort since trial after trial it didn't fix it and it was very time consuming, I tried turning my heat gun to a higher setting but that killed the card completely. It's absolutely worth a shot but I guess my card was too far gone.
I absolutely love this video! Your accent is very ASMR-like too- it's great ^_^ (I only have a big gun like this, not a fancy one, so I'm glad to know it's a viable option!)
I did this while pressing down on the chip itself while in between heating the chip also used fluxpen and ran that underneath the chip. That was 5 years ago and the gpu still going strong even with overclocking
Sir Prancelot it seems to make the solder balls make better contact and puts more material where it needs to be. Just make sure not to over press it and do a even press
Faisal Ayub I’m glad it worked out fine for you. I don’t think pressing down is a good practice though. Firstly because is shouldn’t be necessary because the chip and the board should both be flat. If not pressing on the chip would bend the board even more possibly making things worse. Secondly it’s not done during manufacturing nog during professional reflowing and reballing. Thirdly and maybe most importantly, when you put pressure on the chip you might also move it slightly. The balls are very close to each other and even an offset of a fraction of a mm can be disastrous. The chip normally positions itself by the capillary force of the melted solder. Best not to interfere with that. Just my 2ct.
Just for everyone information this is not a permanent fix! It will likely only get you 1- 3 months use out of card! The cold joints below the chip are oxidized and a simple reflow does not get rid of the oxidation- only reballing will!
Yes, it's not a permanent fix. About the reballing, no, not actually, because the fail is in the chip itself. Louis Rossman has a video that explains this.
This might be better than oven baking. Think about it. The oven may not melt the solder under the GPU. The videos on reballing GPU chips are the best way really.
Not sayin you didn't actually fix this issue, but until I see it live I doubt you did. All we really seen was you heating a part up, we didn't see the behind scene footage you choose to leave out. More likely chances are, lines on a screen like that is either a bad screen, or bad video ram.
This terrifies me but I just know I'm going to have to do this at some point. Re-soldering components one by one gets old fast.Easy enough for old stuff like 70s & early 80s machines. But anything 90s+ gets pretty tight.
+ Ultimate DIY Yup, very, very good tutorial how to easily overheat and fuck up PCB... Heat guns are useless for BGA reflow because it applies too high temperature, so you put very high thermal stress on the PCB and chip, so you can overheat and damage them... To do this in acceptable way, you shout put card on the pre-heater, preheat PCB to around 120 degree C and then reflow using hotair gun... The best way to this is BGA rework station...
Hello everyone. On my 8th pc rig. Using all msi z390 motherboards. Have an issue with the first gen evga 1650 super ultras. The screen just went blank out of no where. I tried all the video outputs, and I've watched enough videos now that I know it can be done and we'll why not try haha. I have the time. My question is can you either I guess upgrade or replace the gpus processing unit.
My advice is to use a temperature gauge after I believe I cooked my card through overheating! It doesn’t work at all now after using the heat gun. I used baby wipes to remove the old thermal paste - could it have been that? Oddly it doesn’t smell bad
Novices like me can't tell the difference between the first screen you showed when you said "you can tell exactly the problem " and the second one at the end and said "It's fixed the card". They look exactly the same to me. What's the difference?
With this fault will it give external vga out display? My dell laptop is black screen but gives external display, the lcd and lcd cable are definitely working
You heated it for about a minute, right? What heat gun is that - is that for taking off the paint with 2 speeds? I have a damn BGB with unlead flux and I tried so far several things (cooking in the oven at 190C does not help, this flux melt at 220 I think). I tried with heat gun for electronics too, nothing. I need more power :) but the trouble will be temperature control.
Yes, about a minute, an yes, it has two speeds and it heats up like crazy. You coud try some temperature control with a multimeter with temperature probe, but it will still be some sort of guessing involved.
Salut! Am un Radeon 280x toxic edition de la Sapphire de aproximativ 5 ani. Acum 2 ani am fost nevoit să o duc în service să îi facă un reballing pt că îmi apăreau artefacte pe ecran. După reballing a mers surprinzător de bine și a ținut mai mult decât mă gândeam, însă problema cu artefactele a reapărut. Crezi că merită să îi mai fac un reballing sau să încerc metoda ta cu heater-ul? Țin să menționez că placa îmi stă între 55-60 de grade când rulează și încă face față multor jocuri de grafică bună. Ar fi păcat să nu o pot salva și tind să cred că merge salvată încă o dată.
Salut. Asta e intrebarea de 1000 de puncte si din pacate doar tu poti raspunde la ea. Personal nu i-as face reballing, pentru ca o consider o reparatie temporara pe bani multi. In schimb si solutia mea s-ar putea sa nu mearga sau chiar sa strice placa daca nu e facuta corect. Deci doar de tine depinde ce alegi.
Bro I have a weird question. I have a dedicated graphics card in my laptop that also has an APU, so i was wondering is there any way that I can pull out the dedicated card and put it on a pcb and use in my desktop?
I have no idea. But if you manage to do it, it does not make sense because a laptop gpu is much more expensive than a similar desktop gpu. You are better off selling it and getting a desktop one.
Hey can this work on motherboard chipsets? When I let it work for a bit without the heatsink and it heats up it works until it cools down, then it doesn't post. I'd try this
hey my laptop condition is like this. everything just works fine, but when i played games with demanding graphics, the laptop will gives blue screen error. is it graphic card problem? ca i solve this with heat gun?
Nice video! i have some questions my laptop GTX1070 chip has no signal, so i wanna reflow it but my heat fan gun also has no temp. display neither, so how can i fix it, and how long did you heat it??
@@UltimateDIY i hope to do that but service centers doesn't wanna repair my laptop and they just said i should change all of motherboard and it will cost at least 1000$ so i just gonna reflow it. how long did you bake chips?
@@야굴 it was too long ago, for me to be able to give an answer. In your place I would search on forums to see how long others did it on laptop gpu cips. Also, use flux.
+MarwinGaming that is up to you to decide. If you have other options, like a pro fixing it for cheap, then do that. If this is your only and last option, that what do you have to lose?
it helped me my gpu is working dead pcs+ hd 7850 into working card by heating right into chip for i dont know 30to 50 minutes when it smeells burning near the core i stop heating and i heat with air dryer full heat thanks
Well the word you was lookin for in the end for the thing you *heat shrink* over soldered wires are called heat shrinks :D hopefully it will work with my two faulty ATI graphics cards, I've got them nearly for free, so I think it's worth trying. BSODs on high resolutions, weird color stripes on desktop.
good Job. I think you've heated the chip a little bit . I think then the cars are made the temperature is not supposed to be higher than 150 degree Fahrenheit and for no longer than 180 seconds. I don't think you had it on for longer , but with a much higher temperature
+Michael Paradigm thank you. Yes, the temperature is hard to control with the heat gun and not enough temperature results in no or just partial reflow and on the other side too muck temperature fries the chip, so it's a little hit or mis. Luckily it survived and it's still working :)
You know you can protect the other components , by using aluminum (aluminium) foil and cut out the center of what you're working on. Be aware that the shiny side reflects heat , while the non reflective side lets it through.
Michael Paradigm The shiny surface only reflects radiation. The heat gun mainly uses air (convection) to heat up things so in this case it doesn’t matter with side you put up. It could be anything that can withstand the heat and will stop the airflow from reaching the card. You’d be right if one uses an infrared heat source.
Don't laugh but I f***ed up my acer aspire 5552 board. It was my first gpu reflow attempt and I forgot to take off the little film on top of the chip so it melted all over it! I tried to scrape it off but ended up disturbing the tiny pieces on top of the chip (not sure what they are called). To top it off, a capacitor came loose and because detached. Strangely enough, the board still powers up, I thought it would be totally dead. However it does turn itself off after about 3 seconds.
I have one more board which is the same to try this out on so any tips would be greatly appreciated. I'm using a 2000w heat gun btw. The lowest setting gets to 400*C
Auch....that's not good. Try to use flux on the second board. Also do some tests on the board that is already dead, just to learn how your particular heat gun works.
@@UltimateDIY yeah I am like reflowing once a week now , since it works great after reflow. Overclocking, heavy games, long hours, doesn't matter, but then the GPU kills itself and I'm like resurrecting it every week lol

by saying 2.30 seconds you mean 230s or 2min 30 seconds? thanks!
Gj I will try,, I think he said ,2m
Will try this on 9600m gt. Artifact on screen. Will update again the progress
@@balazsio yes sir - 2 minutes, 30 seconds. Sorry for confusion.
Great video. Just as far as I am aware reflowing should also be consisting of letting a nice amount of soldering flux under the GPU chip to remove all oxides. Also this isn't most durable fix for GPUs according to most people that work on this. Just a heads up :) Great video anyway. Really educational
Thank you! Until this video I never used flux, but after reading the comments I started using it and soldering/reflowing works way better.
Dunno why some ppl are spreading all this serious HATE! If it's your own card, and you will otherwise throw it away, what do you lose by trying it? DIY re-balling is MUCH more difficult, so best left to techs with experience - and that's gonna cost you plenty..
Thank you!
My card was dead, starting with artefacts, 24h latter black screan, nothing. Card was on my shelf last six months, i found heat gun today, it worked. Im typing from dead GPU...hahahah, hope will last some time, will see. I baked only GPU with heat gun for 30 sec. at 550c (heat gun spec), i used metal foil to reflect unwanted heat from other parts. I did not use flux i will do some testing and report if somebody is interested, Cheers
Glad you revived it :)
3 weeks laters does it still work? Gonna attempt to do this tomorrow or in the near future
thinking of doing the same then sell the card
It unfortunately didn't work for me
I'm sure you will not do that ;)
Thanks you very much it helps me with a Mac Pro dead card. Now is rocking good!
Welcome!
Is it working yet?
This is a temporary "fix". The issue is the bumps that adhere the die to the substrate and not the solder balls between the board and the GPU. Heating the chip causes these bumps to make contact again. After some heating and cooling cycles the bump(s) will break again. This is usually after 30-90 days
After watching a few videos on this subject, that is also the conclusion that I reached in the end. The weird thing is that the GPU in my video is still working.
Ultimate DIY it really depends. Some may last for a good while and some won't. It depends on what part of the chip fails too. I mainly do motherboard repair for MacBooks... Check out my channel if you'd like
Yes, it's a hit or miss kind of a deal...
You have a new subscriber :)
Other video that I've seen stick Kapton tape to the heart of the big chips. Also they apply flux wherever they could so they can see it it's melting. Flux also remove oxide from the old solder making them reflow more readily
Thanks for the info 👍🏻
"this is bloody working" great comment,!
going to try this on a lcd tv main board. have mounted a CPU computer fan over the board and i no longer get my problem. normally the problem appears once the board is hot so i am thinking a bad solder joint. good video!
Hope you get if fixed!
So if you have decided to reflow a pc card then do it a little more efficient and professional.Use a flux paste like RMA223 that is somehow liquid to flow underneath the bga,use your electrical home barbeque grill for bottom preheating and for upper heat the same heat gun until the solder balls to melt and with the lightest poking the bga looks like floating on the solder balls.Floating the bga is the evidence that all the solder under the chip has melt and the chip resolders in its place.Greetings.
+George George thank you for the guide!
put a 1mm long solder on top and when it melts.. add a little time for the underside
Thank you for the suggestion.
I was getting alot of artifacts & screen going off and on using a 5 yr old 560 ti I tried this but I pasted some reflux on all the sides of the processor & hovered the nozzle of the heatgun in a circling motion blasted it for a minute. Works like a charm no more artifacts & blinks thanks man I was ready to give up on my 560 ti I have money ready just incase it does not work I'll go ahead & buy a new 1 very nice so far I'm playing dota 2 on it for 2 hrs straight no issues will update you guys if something comes up.
great that you got it fixed :)
Still working?
Good Job, every repair is a good repair.
Thank you!
Lead free solder, great for the environment, terrible for electronics! lol
So true...
@@UltimateDIY Hey thanks for this BTW! I have to do mine on my HP G62
Welcome! :)
@@UltimateDIY Well, it kinda worked on mine lol just dont move the screen hinges much, or else a big line shoots through middle of screen! Yeah looks like time for new chip, or new computer... nahhh it works good enough for me haha better than no screen!
Randomly bad image is better than no image 😁
Is it still working? Any new video about the card working? I would add a few drops of flux under that chip, preheating the chip and not putting too close the nose and covering the other components with alluminium foil.
Failed a few months ago. Will do a follow up video when I reflow it again.
Ok good. I do have some gfx cards with almost same problem. It is kinda of annoying... Gfx cards should have sockets where we could put gfx chips like in the older days where socket pins were tightly with the pcb.
Cheaper for them to solder and they don't want us to be able to fix them time and time again...
Well i got myself a heat gun recently and 100cc of flux and so far i fixed 3 gfx cards, im using one right now named geforce 8500 gt and it is running on windows 10 pro. and there is one 12cm fan with magnet installed vertically blowing air to the gfx and to the motherboard. so far so good. this 8500gt does really get too hot without any airflow. 80c with just the cooler,
That is really nice. Glad it worked for you :)
Fixed GTX 580 artifacting by just heating up the concerned GDDR5 module. You can identify the problematic VRAM module using the MODS/MATS software. Heating up the core risks damaging it permanently.
Thanks for this info 👍🏼
This help me fixed my red blinking light on ps3!
ps3's die because of faulty NEC/TOKIN caps, not the gpu or cpu dies smh.
@@DarkoPetreski not entirely true. In my experience repairing PS3's the NEC/Tokin caps are the problem *maybe* as high as 15% of the time.
One reason people thought the Tokin's were the problem most of the time was because the heat required to remove and reinstall the capacitors had an unintended side effect of temporarily reflowing the RSX (since they are so close)
Funny enough, I came here to see if I could fix my own GPU from an old Core 2 Duo machine, it's a 7300 LE lol
Going to attempt this repair, hope it work. Thanks in advance for this video!
Welcome! Hope you get it working :)
Did u fix it?
@@illiakolosey4285 No, unfortunately not. I must've tried a dozen times and I was actually noticing some differences sometimes but was never able to get it back 100% to working state. As a last resort since trial after trial it didn't fix it and it was very time consuming, I tried turning my heat gun to a higher setting but that killed the card completely. It's absolutely worth a shot but I guess my card was too far gone.
Woohoo, revived my r9 390, can send the RTX crappie card back now
Thank you..I will try it on my dead R9 270X. The oven method is pretty dangerous tho as it will contaminated the oven used for baking food.
+Rozely Lindim welcome. Yes, regarding the oven thst is true.
I was thinking of that, so I might just go out and buy a cheap toaster oven from good will.
+Jon's Tech Channel that would be the best solution
I absolutely love this video! Your accent is very ASMR-like too- it's great ^_^ (I only have a big gun like this, not a fancy one, so I'm glad to know it's a viable option!)
Hehe, glad you like it ✌🏼
I did this while pressing down on the chip itself while in between heating the chip also used fluxpen and ran that underneath the chip. That was 5 years ago and the gpu still going strong even with overclocking
That is really good!
Good result! What difference does pressing down on the chip make?
Sir Prancelot it seems to make the solder balls make better contact and puts more material where it needs to be. Just make sure not to over press it and do a even press
@@TheF209 OK Thanks for the information!
Faisal Ayub
I’m glad it worked out fine for you. I don’t think pressing down is a good practice though.
Firstly because is shouldn’t be necessary because the chip and the board should both be flat. If not pressing on the chip would bend the board even more possibly making things worse.
Secondly it’s not done during manufacturing nog during professional reflowing and reballing.
Thirdly and maybe most importantly, when you put pressure on the chip you might also move it slightly. The balls are very close to each other and even an offset of a fraction of a mm can be disastrous. The chip normally positions itself by the capillary force of the melted solder. Best not to interfere with that.
Just my 2ct.
Is that a 6200 card? I had one start having artifacts and repaired it by replacing the RAM chips. The RAM was $9.12 plus shipping from Mouser.
Just for everyone information this is not a permanent fix! It will likely only get you 1- 3 months use out of card! The cold joints below the chip are oxidized and a simple reflow does not get rid of the oxidation- only reballing will!
Yes, it's not a permanent fix. About the reballing, no, not actually, because the fail is in the chip itself. Louis Rossman has a video that explains this.
wow...it worked, i fix my GPU, but i used flux....thnx man.
+Ehsan Khan welcome! :)
how long did it last bro
Gonna try this! Have an amd 6850 without any signs of life. It may help...
+Jan Sirkia hopefuly you will get it back. Anyway, it can't make it worse :D
This might be better than oven baking. Think about it. The oven may not melt the solder under the GPU. The videos on reballing GPU chips are the best way really.
I was always afraid of the owen method...
I actually bought the exact same cheap heat gun recently. I'm going to try to do this, using the same method as you. What heat setting were you on?
This has been a really long time ago, so I don't remember that.
I understand thank you for replying@@UltimateDIY
Not sayin you didn't actually fix this issue, but until I see it live I doubt you did. All we really seen was you heating a part up, we didn't see the behind scene footage you choose to leave out. More likely chances are, lines on a screen like that is either a bad screen, or bad video ram.
If you would simply look trough my channel you would understand that it's real. But, no worries, I have nothing to prove to you.
Congratulations, my friend. A method, of course, to be used with great care, but, of course, that is exactly how you used it. Thank you, sir.
Thank you! :)
I am almost sure that you are Romanian xD
Might try it with an R7 265 but I am not sure if it works for VRAM as well.
Indeed, Romanian :)
Not sure also.
Charcoal works best ... get the grill out and fire it up ... leave on high for an hour ... good to go! come back and let us all know how it went
+Jay Graphix did it work well for you? Did you use seasoning?
Would this have been better if some no clean filux had been used to help the solder joint viability. This way the sooner joints may or may not last
Yes, for sure.
This terrifies me but I just know I'm going to have to do this at some point. Re-soldering components one by one gets old fast.Easy enough for old stuff like 70s & early 80s machines. But anything 90s+ gets pretty tight.
Smd resoldering by hand...no fun...

Ultimate DIY
Yup, very, very good tutorial how to easily overheat and fuck up PCB... Heat guns are useless for BGA reflow because it applies too high temperature, so you put very high thermal stress on the PCB and chip, so you can overheat and damage them... To do this in acceptable way, you shout put card on the pre-heater, preheat PCB to around 120 degree C and then reflow using hotair gun... The best way to this is BGA rework station...
Nice to see, but next time put a little rosin ball by the chip and let it seep under the chip to reflow this better. Less risk if you do. ;-)
Thank you for the info :)
*****EXACTLY*****
Im the only one who dont like when he is just pushing the chip all over the board and hitting other components? Omg....
No, I feel the same 😩
Hello everyone. On my 8th pc rig. Using all msi z390 motherboards. Have an issue with the first gen evga 1650 super ultras. The screen just went blank out of no where.
I tried all the video outputs, and I've watched enough videos now that I know it can be done and we'll why not try haha. I have the time. My question is can you either I guess upgrade or replace the gpus processing unit.
My advice is to use a temperature gauge after I believe I cooked my card through overheating! It doesn’t work at all now after using the heat gun. I used baby wipes to remove the old thermal paste - could it have been that?
Oddly it doesn’t smell bad
It's not an exact science without a hot air station, so maybe you overheated it, or a solder bridge formed somewhere under the GPU.
Used 70% alcohol wipes to remove the paste.
This akin to "BAKING" THE BOARD at 385 DEGREES for 12 MINS , Which works but only for Ax. 3 months. Others please advise with technics? - Thanx
I don't think there is any way to permanently fix it, appart from changing the gpu die.
my wife keep asking me what I do with 4 OT grillers!
:))
Novices like me can't tell the difference between the first screen you showed when you said "you can tell exactly the problem " and the second one at the end and said "It's fixed the card". They look exactly the same to me. What's the difference?
The artifacts and weird collors are present on the first screen and not present on the last one.
@@UltimateDIY Ok Thanks!
It'll be the heating of the chip not the sodder that temporarily fixed the failing chip.
Quite possible.
I've seen a few comments saying that this method only works for a few months. What is a preferred alternative method?
You can try reballing. But depending on the price of your gpu, it might not be worth it.
THE BEST PART 6:35
;)
few months - yes. few years - nope. mine gtx580 lived for 2 months and solder cracked again.
I think the higher the temperatures reached by the card, the shorter the fix will hold.
yes...also the cards with two fans...there's vibrating problem. which is not good for gpu solder. new card is a new card
Indeed!
how long does a fix like this normally last?
From a few months to a few years.
What is the model of the heat gun....
It's just a random one. Not a known brand.
Could you write us the actual name of the heat gun or give us a link? Thanks you a lot
Here is a variant: www.banggood.com/custlink/KDGyWsVj3h
With this fault will it give external vga out display? My dell laptop is black screen but gives external display, the lcd and lcd cable are definitely working
Impossible to guess.
Bravo !
I think it is VERY important to use flux
True 👍🏻
@@UltimateDIY I brought back 2 video cards yesterday (with flux) and am now pushing them with FurMark GPU Stress Test to see if it holds up.
Great to hear that :)
You heated it for about a minute, right? What heat gun is that - is that for taking off the paint with 2 speeds? I have a damn BGB with unlead flux and I tried so far several things (cooking in the oven at 190C does not help, this flux melt at 220 I think). I tried with heat gun for electronics too, nothing. I need more power :) but the trouble will be temperature control.
Yes, about a minute, an yes, it has two speeds and it heats up like crazy.
You coud try some temperature control with a multimeter with temperature probe, but it will still be some sort of guessing involved.
Hmmm when I bought a multimer I got temperature probe and I wondered why is that for. Time to search for it.
Hello any alternativs for heat gun? Does blower have effect on it?
Nope, not enough heat. Search on YT for the owen method.
you need FLUX dont do it dry coz it wount last
+FunnyCatsOnline yes, it is way better with flux
how do you control the heat ramp?
Do you think putting flux on it will help?
Yes, for sure!
Salut! Am un Radeon 280x toxic edition de la Sapphire de aproximativ 5 ani. Acum 2 ani am fost nevoit să o duc în service să îi facă un reballing pt că îmi apăreau artefacte pe ecran. După reballing a mers surprinzător de bine și a ținut mai mult decât mă gândeam, însă problema cu artefactele a reapărut. Crezi că merită să îi mai fac un reballing sau să încerc metoda ta cu heater-ul? Țin să menționez că placa îmi stă între 55-60 de grade când rulează și încă face față multor jocuri de grafică bună. Ar fi păcat să nu o pot salva și tind să cred că merge salvată încă o dată.
Salut. Asta e intrebarea de 1000 de puncte si din pacate doar tu poti raspunde la ea. Personal nu i-as face reballing, pentru ca o consider o reparatie temporara pe bani multi. In schimb si solutia mea s-ar putea sa nu mearga sau chiar sa strice placa daca nu e facuta corect. Deci doar de tine depinde ce alegi.
thank you it worked!!!!!
Welcome!
Bro I have a weird question. I have a dedicated graphics card in my laptop that also has an APU, so i was wondering is there any way that I can pull out the dedicated card and put it on a pcb and use in my desktop?
I have no idea. But if you manage to do it, it does not make sense because a laptop gpu is much more expensive than a similar desktop gpu. You are better off selling it and getting a desktop one.
Hey can this work on motherboard chipsets? When I let it work for a bit without the heatsink and it heats up it works until it cools down, then it doesn't post. I'd try this
It's worth a try.
Dude your heating your GPU on a nice wooden desk. My head hurts.
Not nice. This desk I got for free exactly for working on it.
My asus gtx 650 card is not showing any display but the fan is moving, should i use this method
That is up to you to decide. If you have no other option left, then yes.
Hello. What is the name of the tool you use to heat the graphics card?
Hello. It's a heat gun.
"a few months to a few years" that's a bit hopeful ain't it?
Yes, because nobody knows how much it will last. This is not a permanent fix, as no permanent fix exists for this problem.
hey my laptop condition is like this. everything just works fine, but when i played games with demanding graphics, the laptop will gives blue screen error. is it graphic card problem? ca i solve this with heat gun?
Hi. If it's an old laptop and not worth repairing it at a proper repair shop.
How many watts is the heat gun
I think I show in the video
What if my gpu is already reflowed,it can be reflow again?
Yes, but ut will last less and less each time...
do you need a flux to reflow the chipset?
Yes, it's ideal to use flux.
@@UltimateDIY the paste one or the liquid one?
Does not matter.
The cause is the shitty heatsink for these cards, 7300GT rarely fails if is cooled properly with an active cooling system.
+Coroi Alexandru-Mihai sadly so many gpus have shitty coolers on them...
Iwant to upgrad my SPU for my laptop acer to gamer
Nice video! i have some questions
my laptop GTX1070 chip has no signal, so i wanna reflow it but my heat fan gun also has no temp. display neither, so how can i fix it, and how long did you heat it??
I would not do it on such hardware. Better take it to a service.
@@UltimateDIY i hope to do that but service centers doesn't wanna repair my laptop and they just said i should change all of motherboard and it will cost at least 1000$ so i just gonna reflow it. how long did you bake chips?
@@야굴 it was too long ago, for me to be able to give an answer. In your place I would search on forums to see how long others did it on laptop gpu cips. Also, use flux.
@@UltimateDIY is indispesnsible to use flux?
@@야굴 yes.
I want to try it with my GTX 770. You think it's safe enough?
+MarwinGaming that is up to you to decide. If you have other options, like a pro fixing it for cheap, then do that. If this is your only and last option, that what do you have to lose?
Ultimate DIY Okay! Thanks for the answer. 😊
+MarwinGaming no problem. Hope you get it fixed easily :)
temperature and how many minutes?Thanks
About 200℃ for 50sec worked me.
Try on a broken PCB first to get the about right temperature.
My heat gun has only a 100℃ increment.
it helped me my gpu is working dead pcs+ hd 7850 into working card by heating right into chip for i dont know 30to 50 minutes when it smeells burning near the core i stop heating and i heat with air dryer full heat
thanks
Thank you for watching the video and for your info.
Minutes? Don't you mean 30-50 seconds?
he said he used a hair dryer
Well the word you was lookin for in the end for the thing you *heat shrink* over soldered wires are called heat shrinks :D hopefully it will work with my two faulty ATI graphics cards, I've got them nearly for free, so I think it's worth trying. BSODs on high resolutions, weird color stripes on desktop.
+webfischi yes, that's it :)
There is a high chance it will work. For how long, that only time will tell.
Can you do an update video, is it still working after 2 years?
Sean Eredia still working, but it was never used for intensive tasks, so it never got really hot again.
Use kepton masking tape to protect other parts.
Thank you for the info :)
Any update?
Long gone.
No liquid flux?
Yes, you should use it. I did not have at the moment.
subscribed and liked thanks a lot for the idea
welcome and thanks for the sub!
good Job. I think you've heated the chip a little bit . I think then the cars are made the temperature is not supposed to be higher than 150 degree Fahrenheit and for no longer than 180 seconds.
I don't think you had it on for longer , but with a much higher temperature
+Michael Paradigm thank you. Yes, the temperature is hard to control with the heat gun and not enough temperature results in no or just partial reflow and on the other side too muck temperature fries the chip, so it's a little hit or mis. Luckily it survived and it's still working :)
You know you can protect the other components , by using aluminum (aluminium) foil and cut out the center of what you're working on. Be aware that the shiny side reflects heat , while the non reflective side lets it through.
That is good info, thanks :)
thx for info :3
Michael Paradigm
The shiny surface only reflects radiation. The heat gun mainly uses air (convection) to heat up things so in this case it doesn’t matter with side you put up. It could be anything that can withstand the heat and will stop the airflow from reaching the card.
You’d be right if one uses an infrared heat source.
La ce temperatura si cat timp trebuie tinut,te rog raspunde!!!!
Nu stiu mai mult decat ce e deja in video.
Can i use torch burner for reball gpu
No.
Wladimir Wladimirowitsch likes this!

Don't laugh but I f***ed up my acer aspire 5552 board. It was my first gpu reflow attempt and I forgot to take off the little film on top of the chip so it melted all over it! I tried to scrape it off but ended up disturbing the tiny pieces on top of the chip (not sure what they are called). To top it off, a capacitor came loose and because detached. Strangely enough, the board still powers up, I thought it would be totally dead. However it does turn itself off after about 3 seconds.
I have one more board which is the same to try this out on so any tips would be greatly appreciated. I'm using a 2000w heat gun btw. The lowest setting gets to 400*C
Auch....that's not good. Try to use flux on the second board. Also do some tests on the board that is already dead, just to learn how your particular heat gun works.
I refluxed my GT 730 , and it works for a few days but then again the artificats reappear,
Is there a certain type of flux I should use?
No, but probably the card is too damaged. In many cases the gpu die itself has issues, not only the solder joints, so a reflow helps only momentarly.
@@UltimateDIY yeah I am like reflowing once a week now , since it works great after reflow. Overclocking, heavy games, long hours, doesn't matter, but then the GPU kills itself and I'm like resurrecting it every week lol
@@KailasNathX at least you keep it working as long as you can.
