Awesome video. I repaired gas stations for twenty years and usually if you are getting the volt meter out shit is getting real. Loving your video. Keep the great work. Thank you
great video mate, love the fast pace of it, I really don't have the patience to go through chilled down speaking videos. I need to ingest the info quick. You got my second subscribe ever. Keep it going!!!
Ok. The thing with the buck controllers and their power good signal is that they almost always is an open drain output. It means the actual power good signal is an 'always on' signal drawn directly off the main supply through a high value resistor. The controller chip connects this signal to ground through am internal MOSFET that is in off state (hence the name 'open drain'). Whenever it senses the output voltage to be outside an acceptable range, the internal MOSFET is turned on, shorting the power good signal to ground and driving it low. It is done this way probably to safeguard the circuit by driving the power good low in case if the controller is damaged with an internal short circuit.
Just think of all the graphics cards out of warranty that were thrown away because one tiny component failed. Really wish board level repair was more common for GPU's, especially in these times when there's such severe shortages.
In the UK at least, it's very tricky to find someone who knows what they're doing. Many companies offer repair but really all they do is some shitty reflow and hope for the best.
missing the 1.8, and in turn all of the memory VRMS is the most common problem ive been seeing on cards that i cant figure out how to fix. Can't wait to get through this video and learn something.
Thanks for the video with the explanations as you went. I have purchased 6 video cards that are broke and I am trying to learn how to fix them. These are cheap cards, and most of the channels are for expensive cards and they are laid out differently and that makes it tough to try to follow along. I bought 4 nvida cards that are 9800 cards and had 3 others. Ebay has these for 30.00 for 5 cards. Thanks again for the video.
Hello, great videos. thank you very much. Your explanations how all works together are really usefull. I am trying to get into this hobby as well and getting even the most basic informations is very helpful.

First of all, great fuckin' job dude! Very good video, I subbed and will share this on my Twitter page. I have the ftw3 version of the 1080Ti that is giving me a similar issue. I vape in my room, and the ventilation isn't the best and my PC started not wanting to post... You can see where this is going. Thankfully it was JUST the GPU that had vapour condensation on it, but it was quite a lot. long story short, I stripped the card, gave it a scrub with some isopropyl alcohol and a toothbrush. The strange thing is, the PC boots, and games fine, I've even got it overclocked to 2ghz and it's fine, cool and fast. However, the card will not output a signal when the card is past ~42c, the PC will boot up and I can login to Windows, but I have no signal to the monitor. Once it cools down, I get a 'VGA card not supported by UEFI driver, CSM has been enabled for compatibility'. I then go into BIOS, disable CSM and the PC boots. I've already been through a week of all of the software, bios, vbios troubleshooting you could possibly do with this thing and I'm 99% confident it's a problem with either the 1.8v 3.3v or the 5v which was the issue with this card. I don't have a multimeter and wouldn't quite how to use it if I did. Do you think heatgunning the card might help? I don't know what to do, this has been thoroughly annoying.
Great video! Do you buy these cards locally? Saw a local post his Asus RX 580 4gb variation for 30€. Says there is no image output and have been thinking about getting and have been watching repair videos for a while now. Glad I found your channel, used to watch Eli Tech but he stopped posting. Also do you have a community discord server by chance?
Nice job. I repaired a few cards mainly stupid people doing traces and pry damage. I haven’t had the chance to troubleshoot one as no schematics/board diagram plus most cards are different. Just curious how did you figure most cards? Just reverse engineer etc?
really great stuff, i hope you can make it man, you seem to be very smart, but damn like i said before you seem to know the voltage values almost everywhere on the card
Very interensting, great video ... I would appreciate an advice - my friend has an issue with his GTX 980 Strix as it boots to desktop but it crashes (to a pure blue or black screen) a minute or two after entering a game (for example Lost Ark). We ordered a new PSU as we though it would solve the issue, because for a while he was able to use GPUTweak to lower GPU Power Target to 65%, underclock GPU and memory to lowest possible and he would be able to play games for hours. The new PSU (Corsair RM650 CP) did not solve the issue so we changed the thermal pad on the GPU VRM and repasted (GPU) and it did not solve the issue, but now it got worse - even with 65% power target and underclock it would crash a minute after entering a more demanding game. There is no visible damage on the card an it works with windows desktop ... I would also note an oil leak was present on the VRM the first time we opened it and we have cleaned it, so we are now wondering if the card can be repaired by a professional electronic or should we give it up?
The VRM is failing and unable to keep up with the demands of the GPU. VRM's don't leak oil, what you seen was probably the effect of it getting too hot. It can be repaired, this channel has repeatedly proven that. However there may be more than just one VRM that needs replacing as suggested by the observed worsening performance. I imagine it could still be cheaper to repair than to buy a new replacement card.
Hi, I have the EVGA GTX 1080ti SC - i don't see any voltage from the PCI Express inductor. no voltage. component tested fine. Although every other component seems fine. Any ideas? Keith
Very informative video. I'm trying to diagnose my own EVGA 1080 Ti Gaming card that doesn't boot. Nothing looks obviously burned on the board.

Hello. Im a k1, that module missing tbat its count? For example starts with A1 and A0 is missing, does it is A0 or it jumps to B1 and actually B1 its not B1 and it is A0???
Hey after watching this and researching wherever i could i still could not find if my graphics card 1.8v rail is shorted is is still possible to save it or is it gone for good?. if its gone for good does that mean that the main gpu chip is broken or what. would be appreciated if you can answer me. thankyou soo much
its actually 1070ti evga edition that is short right at from the main 1.8v component that we usually checks from and from that every single component connected to it is shorted and the repair shops after immediately telling them they are like its not save able you have to get the gpu chip replaced and stuff

Hi, thanks for the video very informative. I am trying to fix my own 1080 ti sc2. I have no shorts, all resistance measuring look good, I have 12v and 5v. I am missing 1v, memory vrm and gpu vrm voltages. What kind of damage can improperly measuring the 3.3v cause? my 1.8v was measuring properly and after measuring the 3.3v (which was 3.3) the 1.8v is gone and the core no longer gets warm.
@@TechCemetery I measured my 1.8v buck converter and got 12v VIN, 5.33v VCC, and 3.5v on EN. The inductor that is supposed to be 1.8v is actually sitting at 0.138v. Do you think the inductor could be the cause for the problems? Mainly just trying to figure out if the core is dead and if its worth taking to a repair shop becasue I do not have the tools to repair it myself. The card stopped working with a pop sound and a burning smell but with no visible marks on the board. Thanks!
I have a short on 12v... it happen when i measured voltage in mem. Vram whether it get 1.35v or not..and my gpu suddenly... shut down.. After do several check..one of my 12v 8 pin is now shorted.... ..also may resistance for 5v 1.8v 1v is now not at normal value...before this good value.....is it mosfet?

Fantastic video and very informative, I have a reference mode and I have a believe I have a short on the 1v but the card had memory and vcore voltage as normal, any help would be great thank you
@@matthewburke5363 Do you have 1V on the inductor when you turn the card on?. If yes, that's easily a dead GPU. If not, consider the buck converters and nearby capacitors.
@@TechCemetery The inductor and capacitors to left are shorted to ground and when the card has power there is no voltage but I have the correct stand by voltage for memory and vcore, hopefully with a bit more testing I can find the problem and hopefully don’t have a dead chip lol but thank you and hope the channel is very successful 👍
I need help with my 1v buck converter. I’m not getting any voltage. Everything else seems good. Shot I replace it or is it something that is causing it?
For some of these discontinued/harder to get parts, I'd recommend looking for them on sites like Aliexpress, Alibaba, Taobao. Just remember you can't always trust the sellers there.
Hi Mate, great job, I am learning a lot from your videos, please keep posting. I got an issue that I never understand how to fix it. I few cards similar to this one in the video, (standard gtx 1080ti Nvidea founders design), and the cards works normally, but when I try to install the drivers the screen goes black and the drivers never install properly. Identify as 1080 ti but not allow to run 3D applications. I already check / update VBIOS but still no luck. Do you (or someone) know what it could be and how I can check it? Please help ???????
@@TechCemetery hi mate thanks to come back to me. No, I did not try MATs yet, but I will, I saw the video, very good. About capacitors behind the memory, I did not check it yet, but I will do it and report my finding as soon as I complete the above tests. Thank you a lot again.
Hi mate, I did what you asked and the MAT software pass the test without any issues, and no capacitors are missing near to the memory. However, when running the card without drivers i scan the card with a thermal camera and I find out that both of the memory inductors were the hottest spot on the card after the GPU. These inductors were around 55 to 60 C degrees, and this is not normal for a card without drivers and no under any stress. What do you think? Should I suspect bad memory MOSFETs? A memory chips which taking too much power and the memory power bank cannot not hold it up? Please let me know what you think it is and how I can confirm it! Thanks

I have 5v and 1.8v but missing 1.0v because of that nothing at vram and GPU vrm. Could you help me with next steps in locating the missing 1.0v. thanks
The ordering in the video is slightly incorrect. You don't have the 1V rail because you don't have the GPU VRM running. You need to focus on the UP9511p phase controller on the back of the board. You'll want to check if it receives VCC (5V) which is passed through either a 2.2 ohm or 1k ohm resistor, and you'll want to check if you have EN (2V or so) which is passed through a six pin dual transistor I believe near UP9511p.
@@TechCemetery you're amazing, thank you for the advice and quick response, I'll take a look into this. Do you have a discord or anything for further support? If I get this sorted I'll definitely be sending you a donation!.
You have said that the fans are not even twitching. May I ask why? What is the significance of fans twitching? I have EVGA Geforce FTX 1080Ti that was working fine. Then I removed it from the motherboard and it sat unused for a couple of weeks. I installed it into a different motherboard and it does not work. Tried in 3 different motherboards and it will not get recognized. Upon power on, the fans twitch. That is all they will do. The lights do come on. I tested the power connectors for shorts and PCI short testing gets a beep on pins 4 and 7 which I believe is what is supposed to be. Going shopping later today for proper screwdriver set so that I can disassemble it further.
Generally speaking, the 1.8V power rail needs to power on for the fans to at least to try start running. No twitch suggests a failure at 1.8V or before. Take a resistance measurement of the 1.8V, 1V, and memory phase and let me know what they are.
@@TechCemeteryHopefully I am measuring the correct components. Even though this card is the same make/model the board is a little different. 1.8V shows 129 ohms 1V shows 14 ohms memory phase is 59 ohms
@@mark98115 If you really have both 14 ohms and 129 ohms on the 1V and 1.8V rail respectively, then there is a very strong possibility you have a dead GPU.
Also, I just put the naked card into a motherboard and fired it up with windows10. Card not showing in the device manager but I could feel the GPU chip getting warm.
@@TechCemetery sorry, I did not see that you had already replied when I wrote that the GPU was getting warm. After I took the ohm readings I went and put the card into a motherboard to check it out a little more. That's when I noticed that the GPU was getting warm. (kept touching it because I was paranoid about not having a cooler on it).
it's funny how you say in this video youre spending your own money on broken gpus and now i cant even submit a gpu repair request on your site because you're being inundated with broken gpus that people pay you to fix lol
The beginning of the video is just gold I'm going to watch and do the steps over till I actually commit itvyo memory

@@TechCemetery The inductor and capacitors to left are shorted to ground and when the card has power there is no voltage but I have the correct stand by voltage for memory and vcore, hopefully with a bit more testing I can find the problem and hopefully don’t have a dead chip lol but thank you and hope the channel is very successful 👍
I need help with my 1v buck converter. I’m not getting any voltage. Everything else seems good. Shot I replace it or is it something that is causing it?
1v gets enabled by the main PWM controller's PGOOD pin. Check the main PWM controller if it's getting enabled or not.
helllo what is the name of the parts he changed?
Amazing :D
i love u
What resources are you using to find the power on sequence of the components?
Nothing, I know this from experience.
awesome
How do I find a amcg 591 buck converter I can't even locate a data sheet let alone a chip to buy much appreciated brother

That was quick thanks I'm trying to find a nb671lbgq but can't find the exact one they are showing nb671lb or lbq or just L or gq it's weird 😂
For some of these discontinued/harder to get parts, I'd recommend looking for them on sites like Aliexpress, Alibaba, Taobao. Just remember you can't always trust the sellers there.
I have 7 pcs gigabyte 1080 ti not detectable. Can you fix them?
Yes, send me an email. It's listed in the description.
Hi Mate, great job, I am learning a lot from your videos, please keep posting.
I got an issue that I never understand how to fix it. I few cards similar to this one in the video, (standard gtx 1080ti Nvidea founders design), and the cards works normally, but when I try to install the drivers the screen goes black and the drivers never install properly. Identify as 1080 ti but not allow to run 3D applications. I already check / update VBIOS but still no luck. Do you (or someone) know what it could be and how I can check it?
Please help ???????
Have you tried running MATs? it's a memory testing program - I have a guide video on it. Is the card missing any capacitors behind the memory?.
@@TechCemetery hi mate thanks to come back to me.
No, I did not try MATs yet, but I will, I saw the video, very good. About capacitors behind the memory, I did not check it yet, but I will do it and report my finding as soon as I complete the above tests. Thank you a lot again.
if you got an address where to donate, I will be pretty much happy to put my contribution to you into making these amazing videos and support.
Hi mate,
I did what you asked and the MAT software pass the test without any issues, and no capacitors are missing near to the memory.
However, when running the card without drivers i scan the card with a thermal camera and I find out that both of the memory inductors were the hottest spot on the card after the GPU.
These inductors were around 55 to 60 C degrees, and this is not normal for a card without drivers and no under any stress.
What do you think? Should I suspect bad memory MOSFETs? A memory chips which taking too much power and the memory power bank cannot not hold it up?
Please let me know what you think it is and how I can confirm it!
Thanks

I have a graphics card can you help me to fix
Hello can you help me? I have same problem with my gigabyte 1080 ti extreme
I can't give any advice without a diagnostic - resistances and voltages for all power rails.
What do i do if I have 6 shorts on my external 8 pin power conector
6 beeps on an 8 pin indicates a short on the 12V rail. If you check the inductor connected to it it should also beep.
@@TechCemetery what to do?
I have 5v and 1.8v but missing 1.0v because of that nothing at vram and GPU vrm. Could you help me with next steps in locating the missing 1.0v. thanks
@Tech Cemetery any help would be greatly appreciated thanks
The ordering in the video is slightly incorrect. You don't have the 1V rail because you don't have the GPU VRM running. You need to focus on the UP9511p phase controller on the back of the board. You'll want to check if it receives VCC (5V) which is passed through either a 2.2 ohm or 1k ohm resistor, and you'll want to check if you have EN (2V or so) which is passed through a six pin dual transistor I believe near UP9511p.
@@TechCemetery you're amazing, thank you for the advice and quick response, I'll take a look into this. Do you have a discord or anything for further support? If I get this sorted I'll definitely be sending you a donation!.
I think I've found the issue, is there a way I can post or send a pic to confirm
@@RahmanKhan-lk2wx I have an email listed in the about section of my youtube channel.
You have said that the fans are not even twitching. May I ask why?
What is the significance of fans twitching?
I have EVGA Geforce FTX 1080Ti that was working fine. Then I removed it from the motherboard and it sat unused for a couple of weeks.
I installed it into a different motherboard and it does not work. Tried in 3 different motherboards and it will not get recognized.
Upon power on, the fans twitch. That is all they will do. The lights do come on.
I tested the power connectors for shorts and PCI short testing gets a beep on pins 4 and 7 which I believe is what is supposed to be.
Going shopping later today for proper screwdriver set so that I can disassemble it further.
Generally speaking, the 1.8V power rail needs to power on for the fans to at least to try start running. No twitch suggests a failure at 1.8V or before. Take a resistance measurement of the 1.8V, 1V, and memory phase and let me know what they are.
@@TechCemeteryHopefully I am measuring the correct components. Even though this card is the same make/model the board is a little different.
1.8V shows 129 ohms
1V shows 14 ohms
memory phase is 59 ohms
@@mark98115 If you really have both 14 ohms and 129 ohms on the 1V and 1.8V rail respectively, then there is a very strong possibility you have a dead GPU.
Also, I just put the naked card into a motherboard and fired it up with windows10. Card not showing in the device manager but I could feel the GPU chip getting warm.
@@TechCemetery sorry, I did not see that you had already replied when I wrote that the GPU was getting warm. After I took the ohm readings I went and put the card into a motherboard to check it out a little more. That's when I noticed that the GPU was getting warm. (kept touching it because I was paranoid about not having a cooler on it).
my card has the same condition
Excellent video mate, but for gods sake slow down and think before you speak then you don't have to say it three times.
consider buying cheap gpu like 650ti , 750ti . more subscriber wiill come
it's funny how you say in this video youre spending your own money on broken gpus and now i cant even submit a gpu repair request on your site because you're being inundated with broken gpus that people pay you to fix lol
17 minutes of "ehm... yeah... I mean no... errr.. sorry I mean yes... well, I think, maybe."
huh,,, i wonder if u could fic my card :D
