Buildzoid: I don't remember how power connectors are wired Steve: But you could find out if you had a modmat

"Reported for excessive violence" 😂

I like your funny words, magic man.

I would like to see a video where you explain it a bit more theoretically, as in "Buildzoid draws schematics in GIMP". You could explain the things you are stabbing, how they are connected, why healthy resistances are how they are, etc. That would help me understand what you are doing a lot.

who care about new rtx series, THIS is the content that I want 😂

I've only watched the first part of the video where you go through and test the Red PCB 7950. It is very insightful and helpful that you go through it slowly and explain everything you're doing while you do it. I recently ordered a used motherboard on eBay and noticed that it was missing a MLCC capacitor on the back behind the Vcore VRM. The board seemed to work fine as it was a 6-phase VRM on a Haswell platform with a FIVR, but I went down quite a rabbit hole trying to figure out what kind of MLCC I needed and then soldering on some replacements. The kind of breakdown you are doing on these GPUs is great experience for me to learn more about power delivery, and I can't thank you enough for sharing your knowledge on the platform!

There's a ghost saying "yea" at 20:29, buildzoid consider an exorist before it starts lifting the liquid out of your LN2 pots mid OC

I like this type of content a lot! You must definitely look into doing more of these.

If I’m not mistaken, that first card MAY be mine. Can confirm that a fast psu was used.

Awesome, just what I'm looking for while diagnosing dead ish GPU , since no KZfaqr wants to try fixing it lol

Thank you so much for this content. This is gonna be really helpful to myself and others

12:55 - The smoke does come out of the location of the short - it comes out of the location with the weakest link. Which is why you desperately need a current limiting benchtop power supply for this sort of thing.

I was recently thinking it would be nice if you could do this kind of video showing what are you looking for in dead gpu and here it is. Thanks!

Great content, I love it! Thank you.

Thank you for this well done video.

Thanks this content is interesting we’re will you get the replacement inductors and fets from

great video, would it be the same way to try and diagnose an issue with something like a polaris card ?

The first victim, err patient!

I loved it mate, great job

Love how he's mastered his craft.

Where do you get the schematics to know where to take measurements? Been wanting to troubleshoot a card but not sure what's what, honestly.

got a 1060 with a short at the 12v pcie slot gpu let out smoke so removed the core theres still short what can i do to check where short is can it be on the ram ?

I wish you knew how long I have waited for this. Like two haircuts ago lol.....

Excellent! Thank you.

G'day Buildzoid, Thanks so much for this, now I can do some probing of my Sapphire R9 270X Toxic that has no signal out 😁

That's what we've been waiting forrrr

Where were you checking for the mosfet shorts? How do you know which power supply on the board powers what? You say this one is for Vcore, this one is for memory............ How do you know? Thanks

Can you help Me fix my vega 64 gpu thr psu cuts power to it when I ip the resolution on my 4k monitor so I suspect it's vram. ? This all goes above my head a little

BuildZoid is MY bestfriend :)

i need more videos like this

I got a random 6870 msi Hawk sitting here. Received it without heatsink from someone who threw it in with a GTX280 that I bought. I always wondered if it still works or what was wrong with it. I did not dare to plug it in, in case there was a short. I stabbed it now like you did and I found ~2.6 ish Ohms for core, 16.X for memory and 80 on a random choke which is probably some aux stuff for the rest. Some kOHms from 12V to ground. Fuses close to the power connectors are intact. Should be safe to try it? Just gotta find a fitting heatsink.

OUCH! They looked sharp!

@Actually Hardcore Overclocking Hey mate, I have an HD7950 Dual X here as well, same one as in this vid (last card). It suddenly gave a black screen during gaming about 2 years ago and I still have it. Recently wanted to find out what was wrong with it and if I could maybe fix it myself, so I can put it in another system. Found that there was a ceramic capacitor missing. Long shot here, but if I would give you the location (back of the card, just below and left of the bottom left heatsink screw) and/or number (C2119) would you maybe be able to tell me the specifics of that ceramic capacitor? Like the metric code and resistance that it should be, I don't know anyone else who has this card, just hoping you would see this and reply. 🤞😅

I never thought I'd be listening to Kermit the Frog explain the PCB components of a GPU to me. 🤷‍♂️🤣

I've got one of those PowerColor HD 7950s that you start with and want to gently caress it with my EVC2. Would you know if the four blank through-holes next to the fan header connect to the Chil's I2C pins? I'd check myself but my mate blew up my multimeter and I'm waiting for a new one in the mail.

Where would the best place be to learn where to probe different cards/pcbs for voltage? I bought a job lot of broken cards on eBay and I want to be able to repair them probably if there broken, Idk if anyone will see this comment but I’m new to learning electronics repair however I do have some skill and it’s good to learn :) Interesting video though!

Can we get a toaster reflow station video please?

I got a GT1030 with burned HDMI and after probing PCI-e 12v to ground it has a set resistance... and then DROPS. If put into mobo it blocks POST. Is there any reasoning behind this? xD HDMI was desoldered

Are you going to tighten the timings on video card memory

Here is the thing, I have a very nice MSI RX580 8Gb oc lying around. I'm trying to fix It. After playing a little bit with the multimeter I couldn't find anything wrong. For my surprise the card gives video but It contains artifacts. I was talking to the previous owner and he told me that the card didn't post anything, but It does. He told me that the behaviour started to be strange, he did a memory test and the memory was in good shape until he got no longer video out. What is the next step? should I use the heat gun trick? is there any video that explains what is the science behind this? thanks

Title: Reflowers: HEAT THE BOAAAARD!!!

Question.. for the r9 380, there are mem chip slots empty. I’m guessing those are the pads there? If so, is that what’s under the occupied mem chip slots? & can you put mem chips there to add to the mem capacity?

Where'd you get them? :)

BZ should film such videos with TF2's medic voice. - Anozer successful prozedure! We need more body bags for ze kards! Mein probes got dummkopfed with all ze stabbing!

Doesn't bubblewrap build up a static charge? I remember unpacking things with that stuff and having my armhair standing up.

I just wanna know where you learn all this stuff because I want in

21:03 If I'm not mistaken there's quite a bit of PCB discoloration around the socket. I wonder if the ASIC itself just burned itself out.

Which card(s) were the best of the 5700XT series? (i expect its AMD's own on #1, asus #2 and Pow.Col. on #3.)

Its okay Buildzoid. We've all "overestimated our probing skills" once or twice. Just part of the game.

Have you made a video on replacing/upgrading mosfets on cards? I need K0393 and K03B7 or equivalents for my GTX 980. Reliable places require buying hundreds of each and I'm afraid that my ebay purchase of 5 for $4 are probably going to be fake. As far as finding more available equivalents that might be better with more amp rating, I'm an idiot and have no idea if a mosfet that says "8mΩ Rds on" will work in place of one with "3.3mΩ Rds on " at 10v. So I guess, which parameters besides 30v and Amps have to be the exact same? OK to have higher amp rating? Will the driver care?

ND - no display? that black stuff is BGA underfill

Finding bargains on Ebay can be hard. Those selling broken stuff for twice retail new, gah.

#ActuallyHardcoreOverclocking what manufacturer do you think makes the best AMD aftermarket card??

Buildzoid, put a webcam on these videos. I think would be funnier to see your face when say these funny things :)

I have a 8 gb RX 470,, Chip got hot but no display, I then put it in as secondary card and windows crashed as soon as I installed the driver. I then heat treated the VRM and chip for 6 min at 280c. I've put it in the pc, and got Display, then the PC shut down and now the GPU trips the PSU, I am by no means a Electroic tech guy but Ive learned a few tricks, just not sure where to search for the short. I have a multimeter. Not expecting much but any direction will help :D

The black stuff is on the mem ics is factory for powercolor

I really miss the red ATi\AMD pcb's :( EDIT: 1:18 OH NICE! Your a man of fine taste God&Jesus bless you my friend ;)

I got 0.2 Ohm for Vcore, how bad is that?

had an rx 570 die on me, controller/driver/ and mosfet died. idk which one died first in the chain reaction but it also killed my m.2

i want sub in your patreon ... you have videos about how repair graphic cards? and how to diagnose

Very interesting

15:50 you'd think that, until you get a box of stuff that's just bare PCBs wrapped in blankets (along with heatsinks and some other random parts), all of which smells like both smoke AND dogs, with a free complement of hair everywhere (including in the motherboard socket). That stuff had to get some serious deep cleaning...

I cant believe that people still put card on that oven (or toaster) torture as it's always a gpu fault with these things and heating only GPU area (from behind without nozzle or from front side around die with small nozzle) will resurrect a card without temperature stress on all other components and premature death of some of them soon after. I fix who knows how many cards that way and only one ever die again (I can be sure just for 3 month warranty period I give for fixes like that but I hear many times "hey, it still work" but not even once someone mention that card die again) was my own card and that was only after few overheating sessions because "someone" didn't notice that loose cable from m.2 to sata adapter stop a fan. Oven jobs usually have life from few days to few months, at a time I also do them (10 years ago) I never give any warranty because it was better for me just to charge less for fix and avoid problems later.

i actually dont know anything that you're talking about, but its cool

This is why they call him Captain Stabbin'.

I have a broken sapphire 290x, do you want it? details: cheap power cable melted and fried it. no visible damage.

Uploaded 5 minutes ago and there's comments from days ago👀👀

God I wish there had been a sapphire fury in the pile so I would know what to check

8:05 Just get yourself a cheap buck regulator module with a display and replace the post with some 10k ohm 10 turn pots with real knobs on them. Power from a PC power supply and set the voltage and amperage to minimum before connecting to the board. It works but its the cheap 'o method...

The memory chips from the 380 were stolen by AMD themselves when they decided to never release a 384-bit 3/6 GB card with Tonga. The Tonga core has the memory controller for it, and someone had a fully functional prototype, but apparently at the last second AMD changed their mind.

That bubble wrap is suspiciously red BZ!

Might be ND, "Not Dead" for that bad audio card. Or possibly WD, "Water Damage"...

My secondary PC has a working Red PCB HD7950 "boost state" :P

Get your poke on.

The alienware PC comes with a red PCB rx5700 in case you wanted a newer GPU in red

Mosfet looking kinda sus

PEGI18 Streamer violated YT regulations LUL.

WD = water damage?

Can't stick head under camera because hair is too OP.

why don't you have a current regulated PSU? you could literally use a current controlled buck converter (5 USD?) or a cheap lab PSU, which is like 50 USD.

Do people send you their cards and you fix them ? What’s the fee?

He he... 'probing speed'

I had to read the title twice.

If BZ is trying to build a stack of GPUs as high as Hardware Unboxed's, good luck to him. :) ;)

Coming back in 2022 where non-functional GPUs are going for $200-1000...

Man how are there comments from days ago on a video uploaded today

lol don't just heat things unless you know how to measure, oh i'm measuring wrong .

I believe the probes are plated brass... Sharpening tips won't work well.

Quid? I didn't know where he was from, but I do now lol.

Maybe you could have explained more thoroughly what kinds of resistances to expect from which voltage rail. All I learned now is that the core is about 2 ohms unless it's not. But I dont care, i didnt come to learn stuff, I came to see you "stapping not working AMD GPUs with a multimeter" and taking about it.

what is quid?

"Stabbing not working." Well, try not stabbing, see if that works.

I wish I could stab GPUs like you, I have a dead Reference 290X lying around but I haven't used the oven/heat gun method on it. After using a multimeter it seems to be not receiving VCORE and VDDCI Voltage.

"Stabbing not working" vs. "Stabbing not-working." Discuss.

Red Mem is Sus

You can put gpus in the toaster? Nice

The moment your boss is waiting for you , but buildzoid is stabbing gpus with a multimeter so we all know you get an *urgent* family call :D

Pretty sad to see him spending cash on not working GPU's when you could've just answered my email about my donation with working GPU"S.... Or maybe there are so trash that don't need even a reply ? Sad to see this

WD = Water Damage

You shouldn't stab your GPU's.
