Nice work! Always impressed by your skills as a troubleshooter. I was 30 years in industrial automation and robotics; retired now. (We just replaced bad cards and threw them away unless the manufacturer was covering them under warranty!)
MSVDD is indeed a huge pain on the higher SKU ampere Cards. it's still vCore, but Nvidia was trying to skimp so much on VRM design with Ampere that they had to split vCore into two separate inputs to help it be able to handle the Amperage needs. which ended up as a mess anyways, with 3090's tending to have their VRM blow up from being so underpowered. atleast they did fix that for 3090Ti and that no longer has the MSVDD split, the VRM being actually good, but a bit late to fix that by that point. amusingly since 3080Ti's came out several Months later, those Cards tended to have a less underbuilt VRM compared to most 3090 Models, so the Flagship tended to blow up while the cut down was farrrrrrr less likely to.
Enjoy the videos, I can follow what your doing up to a point, I followed the whole video, but at the end you stumped me, on what you did to fix the card.
You are making my brain hurt. This is a great video. So much knowledge you pass on. Thank you for giving us some of your valuable time as you make these videos. If you sold things I would support you and purchase things from you. It is actually a nice way to make a little income. You should consider it.
Thank you for this very informative share. I’m encountering a somewhat similar issue with a short circuit on pin 36 of U812. At 6 minutes into the video, you recommend removing Q13 and testing with a power supply capable of limiting the current. Could you specify the value to which the current should be limited to avoid collateral damage?
Mr Wizard did it again! While showing us the level of knowledge needed to fix these bloody things.... He is definitely on another level 😁 I don't know if I should complain about the bad illumination of your face, I would suggest a ring light pointing at you.
So all these driver MOSFET have a Temperature reporting output on the same bus (probably a serial bus) and they send messages to the controller with some ID in order to for the controller to know which is the MOSFET and the rail.
This happens a lot on Am4 Mainboards as well, where VDDP gets disabled as soon as you power it up with a CPU in it. Also a transistor that you can remove, so the EN doesnt get disabled.
very nice repair and troubleshooting thanks! Are you aware that your oscilloscope has a web interface/VNC server so you don't need a camera pointing at it? :)
Strange how that works.Have you ever spoken to someone like ChrisFix about odd issues with boards? I just want to say you do some amazing work( broken board/broken trace.)😎🤠🧔♂
Dear Northwestrepair can you please tell me where can I bought that test power supply for graphic card 🙏 I also do repair graphic cards and motherboards just like you, thanks in advance 🙏🙏
A 0 ohm resistor is just a wire link that can be placed by a machine, it's there instead of a direct connection because the board is designed to accommodate a variety of similar but not quite identical components, so if they have to source mosfets or memory or similar from a different manufacturer then the 0 ohm resistor or other valued resistors are placed or removed to change the circuit layout slightly to make that slightly different component work with the rest of the board.
Because the AMD cards have completely different board designs, and this annoys him I guess. He is used to nVidia cards, so it makes harder to find the issue(s). And he repairs more nVidia cards, because obviously much more people have them, than AMD cards. And generally nVidia cards are more expensive, so it's more likely someone would spend money to fix it.
He explained ot Nvidia board are cheap shit but the silicon is usually good AMD cards the boards are nice but the silicon dies easy so every so often you see an AMD card and its a dead core Nvidia it's mostly a board repair
Do you think EVGA would get back to making GPU's if Nvidia offered them a better deal to where they could profit ? I hate that they stopped making them it's all Nvidia's greedy fault . Imagine what they would make for the 5090 coming out ...
I didn't see your current room on the million dollar house you walked us around! Scamming us! I want a refund for the $50 advance fee that means you look at my GFX card in 2026 instead of 2028!

Pretty interesting context, thanks 👍
someone talking about overclocking called MSVDD 'core cache'
Excellent diags Tony! Keep up the good work! Have a good rest of the weekend!
It's good to be a smart guy! Excellent work, Tony!
Thankyou..excellent learnings,fault findings and outcome.again..best content imho. magic stuff
Excellent work, indeed! 👏🏻👏🏻
Extremely detailed and complex. My work with consoles and vr headsets tvs and phones is basic cimpared to this. This is truly next level repair.

Always a good video to watch with plenty of things to learn, thanks Tony!
damn I just subbed and already a new vid? Great vid upload rate
❤ Awesome video ❤
i have the same issue. thank you for that tip. mine has overheating mosfet. after replace it and put the diode back. it went normal.
Woooo! Would've never figured this one out!

No. It's just voltage to the same pin.

Epic stuff man;
Damn I always feel stupid when people talk about electronics and schematics. Glad I can just pay you money to fix stuff.
You are amazing sir.
be sure to tell Big Boss I said hello
hi friend, what is the name of the power supply to power the video card?, give me the link.
i like to buy a short finder whats is the dicountcode i need the 0.3% discount 😬
do you use webcams or capture cards and camera?
No
great work

What happened to the OG northridgerepair guy?
Dear Northwestrepair can you please tell me where can I bought that test power supply for graphic card 🙏 I also do repair graphic cards and motherboards just like you, thanks in advance 🙏🙏
I think you have to build it yourself ...
Buy it from big boss
its in his store
You should be able to do a similar thing using a bench power supply with a variable regulated (current limited) output.
The multimeter that you can buy at our store 🤣🤣🤣
"I don't sell any multimeter. I sell my time!" 😅😅😅😅😅
😂
Northridge shade
Can you make a video only about your voltage CPU repair thing and it's features. 😅 thanks
Always good to learn something new....if your not learning your not living lol
I worry about these manufacturers making the cards not repairable. that will be next... like they are doing to everything else.
he's the best he's the best he's the best he's the best he's the best he's the best i learned many things.
So what manufacturer do you prefer
What is the name of the gpu power controlled tool?
I need one like that
What software do you use for schematic?
"half dead Mosfet"! According to the Sorin doctrine the life consists of all kind of shorts!
Wait.. A 0 Ohm resister? Wouldn't that be a passthrough?
A 0 ohm resistor can be referenced as a jumper or fuse (lower current), developers may also make use of them as circuit separation for testing.
So a jumper or passthrough...@@chihofung6860
What card/model do you repair the most?
Nvidia random models
where do u find these schematics for graphics cards man i needed one for my gigabyte gtx 1070 8gb g1 rev2 board and couldn't find one anywhere
Dang! That was a rabbit chase
Its Tesla wireless connection to that diod
Need resistance value on 1.8v and memory
Normal
So what's the fault and the fix? Can some one time code I watched the whole thing but didn't see it
Tha AI voice is also nice.

Is there any card you DO like?
MSI is not too bad
😮
@@northwestrepair lol can't tell if he's trolling or not.
how did made that toy? can you share?
Can somebody tell me why use 0 ohm resistors instead of a wire link or no resistor at all required. ?
A 0 ohm resistor is just a wire link that can be placed by a machine, it's there instead of a direct connection because the board is designed to accommodate a variety of similar but not quite identical components, so if they have to source mosfets or memory or similar from a different manufacturer then the 0 ohm resistor or other valued resistors are placed or removed to change the circuit layout slightly to make that slightly different component work with the rest of the board.

No. Just a 3d printed band holding it attached.
i dont understand where is THE FAULT
in this case ?
