Asus Strix GTX 1080 Ti Repair #1 - Not detected

[@morphd82]

Since we can't get a datasheet for the uP9013Q, UPI make another 2 phase controller with the same pinouts part# uP1666Q that has an available datasheet to use.

Nice videos dude, only one question: From where do you take the missing or broken parts of the cards? Do you take them from the same cards or even from a generic cards or even you only buy the pieces from some kind of shop?

[@DonSh3]

Subscribed; thanks for the great videos! I'm currently working up the ability to fix a pair of RX580s that were damaged in a power surge. I'm a EE and have all the tools, but I need to familiarize myself with the anatomy of these cards. The funny thing is that one of them prevents the PC from booting and will damage whatever PCIE slot it's plugged into. The second card is not detected, but the PC can boot with no damage to the slots.

@Tech Cemetry I have the same gpu with a strange problem. The card works just fine, but if you put some load on the gpu the screen will go black and come after that. Drivers and vbios are the latest but still the problem persists. It seems that when the pc wants to use more power on gpu it will not allow to. After several black screens i get bsod with tdr_video_failure. What could be the problem ?

[@TechCemetery]

Most likely the GPU. You could have poor voltage regulation on the VRMs, or something wrong with the PCIe interface ( capacitors etc), but again, most likely the GPU.

I would consider the bios and the resistors around it as well as the GPU itself. In my limited experience, a reball is required if the GPU is not detected (assuming the GPU isn't itself bad).

[@ewardw6062]

Under the GPU1 there are 2 lines with resistors or capacitors?

My 1.8v rail is getting 1.8v, however, the resistance is only 433ohm, could it be the buck converter? I'm not sure who else to reach out to for help, you're the most knowledgeable person I've found. The card is being detected and boots into Windows, but only when the card is ~42c. Once it heats up the BIOS gives me a 'vga card not supported by uefi driver, CSM has been enabled for compatibility'. At which point I can let the card cool, disable CSM and boot right back into Windows. Games fine, and overclocks to 2ghz absolutely fine, cool and quiet. Not sure what to do.

[@TechCemetery]

I've already answered your question, it's a dead core meaning sell the card.

Hi, and many thanks for great videos, I have already subscribed and learn so much from you. I have exact the same asus graphic.card with no display and on this particular buck-converter there is a nr: (AMCG 550) but in my card I can see the capacitor left to the black resistance (5 Ohm) with the L.h on it beeps on both sides. both buck-converters has the same capacitors that beeps on both sides. do you think that it is the same problem with buck-converters maybe?. I tried to find schematics for this card but no luck. and i'm new to this repairing graphic cards area. so any help would be much appreciated. Thanks again and cheers :)

[@TechCemetery]

Hi, You'll have to be more detailed, the same buck converter is used for the 1.8V, 1V, and 5V rail. There are no schematics for graphics cards unless you are an authorized repair center. You'll want to measure the resistance of the memory phase, 1V, and 1.8V power rails. A short or abnormally low resistance can suggest a dead GPU. Also, can you provide a detailed picture of your short capacitors? I'm having a hard time making out which ones you're talking about.

[@faridsh.8669]

@@TechCemetery Thanks so much for your prompt reply, I followed your instructions on voltages, and I can measure all of them 12V, 5V, 1.3V and 1.8V , 1 V are present.

Resistances across the voltage rails?. For an unresponsive card, the standard is to check BIOS, PCIe data lines, and Quartz. In your case, there's not much advice I can give you - I don't get a lot of cards that were pulled out live.

Greetings, I am heaving an issue with exactly the same card. Problem is that card runs normally on standby and crashes when on load. By inspecting it i could hear the coiling on inductors for memory buck converter. And indeed, whole area was overheating before card crashes. Filter (power bank) capacitor on V-in for memory power controller was also overheating. I am assuming that it is not working properly due to faulty mosfets controller. I couldnt find the datasheet for uP9013q. I can see here that you have used RT8815A to replace it and it was working, Am i rite? If so please confirm that is the part you used to fix memory power issue. Also if you have any suggestion why the power for the memory is overheating it would be helpful. I was measuring the voltage on the output of memory power and it is normal on standby but as card starts to run and heat, voltage goes up until card crashes. Again, thanks for this video and for your help.

I did not use a RT8815, I just referred to the datasheet. I used a replacement uP9013Q. Generally these cards that die under load tend to either suffer from very small amounts of memory corruption, or have dying GPUs.

I hope I have people like you in Spain

[@vernanflexx6079]

How can I test the GPU memory bank? I would like to contact you for something I have in mind.

[@TechCemetery]

I'll have a video shortly on running memory tests on select Nvidia GPUs.

[@Swc_Leader]

@@TechCemetery what about amd GPU?

[@cgulayni1777]

how fix PLEASE POWER DOWN AND CONNECT THE PCIe POWER CABLE FOR THIS GRAPHICS CARD

[@Roman9441]

Damn i enjoy you repair VGA :D i wish i could send you one to try haha :D , nice video

[@ScoopDogg]

i heat gun the processr on the gpu its a common fault or reball it if you cant get aanything to work, its a temp fix

[@Anax159]

Hi bro. I have 1080ti it's working but some time it stop working what should I do

[@shermanbaldwin514]

I bought a 1080ti on eBay and of course took too long to test it out and now I can’t return it. The card is dead. I get a post error. And a code 43 if the pcie cables are disconnected. Can I send it to you for repair?

[@TechCemetery]

I have an email listed in the about section of my youtube channel. If you contact me there, I'll consider looking at it.

[@FlyingVideos]

Where are you located and do you repair cards for customers?

[@TechCemetery]

I only repair cards for other people if the card is particularly high end or they have a lot of the same model with the same symptoms/issues.

[@FlyingVideos]

If I don't have 5 v on up9511p? What can I check?

[@TechCemetery]

There's a resistor that bridges the 5V rail to uP9511 VCC. And a capacitor that sometimes goes short.

[@ovymar1924]

@@TechCemetery Thank you 🌟

[@ovymar1924]

And one more thing,under the PGU1 there are 2 line with 8 resistors or capacitors?

[@DrKaku01]

i just left a card outside of my computer for months and it stop working :l what it could happened?

[@Friend_of_the_One-Eyed_Ladies]

Probably knocked a couple components off moving it around. Or the kids did... and hoped you wouldn't notice.

[@DrKaku01]

[@FlyingVideos]

Really enjoy watching these videos. I have a R9 390 which is in bad shape. I have removed the GPU chips and I cannot source a replacement. Number on the old chip is amd 215-0880030. I think I could reball and replace the chip if I could get one. Can you help?

Do you still fix these cards?

[@alvinj6006]

Could you do a repair on my graphics card I will pay..

[@Swc_Leader]

Did you ever get a response from him?

[@zeferrum]

Please note that my Asus Strix 1080TI came with a uP9022P and not a uP9511P from factory

[@TechCemetery]

Yep, as I now know, some Strix cards do have that instead.

[@zeferrum]

@@TechCemetery Do you know if they are interchangeable ?

[@brokenwingsparanormal]

I have this same card with issues. how much are they worth in brick form? lol

[@meranjana]

my gtx 1060 strix is also missing 1.8v and vrm voltage is also 0v .. any ideas?

[@TechCemetery]

Do you have 5V? if not you need to focus on that. For the buck converters, check VIN, EN, VCC

[@meranjana]

@@TechCemetery nope. No 5v either.

[@TechCemetery]

@@meranjana 5V is usually the first voltage rail to turn on. Without out none of the other voltage rails can run. Check the 5V buck converter. EN is usually 3.3V, VIN is usually 12V and VCC should be 5V.

[@meranjana]

@@TechCemetery there are two 5v converters one is above the pci-e lane the other is right below the vrm. That below the vrm one seems to vorking when i poke the probe to the coil it shows 5v. My question is, is that a 5v converter or is really that a defect? That one which above the pci-e lane is givng 0 v.

[@TechCemetery]

@@meranjana There is only one 5V buck converter and in your case, it outputs 5V. The other ones output a different voltage as these buck converters can be configured to output a wide range of voltages. The buck converter you're referring to is either 1.8V or 1V. You need to find the 1.8V buck converter and check the resistance of its connected inductor, as well as the voltage.

[@elihere1242]

How much do you charge to fix them? Do you fix PSU?

[@TechCemetery]

I don't fix PSUs, and I almost never take other peoples cards for repair.

[@dilanhermosillo5974]

How did you flash the bios?
