@Ben T. I understand that someone can like best of best... but if PC draft 1000W from wall its sometink wrong... you NEED to dissipate 1000W worth of heat... On the other hand you don't need a heater in your room, buuuut you will have problem in summer :)
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.
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!
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 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.
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
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!
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.
@Ben T. There certainly is a second, unpopulated header directly under the fan one that only has three through-holes. I can say for sure that that's a fan header minus the PWM. If the four pin one is for I2C I've got no idea what SCL/SDA and ground will be, let alone what the fourth is for.

@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. 🤞😅
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
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
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...
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

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?
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
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?
@Ben T. I'd love to but digikey and mouser sources require purchasing 100s of each, so I bought some on ebay, probably fake, I'll wipe them down when they get here.
@Ben T. china. 5 for $4. Still learning. Trying to find out if the resistance from drain to source when closed means anything and how close the replacement's should be to the original or if that matters at all. Because I have no scope, but I was wondering if I could get one of those $30 ones and use it.
google "basic electronic components" and start there. next step could be learning how they work together and how they can look and have different properties/uses in specific circumstances like in a gpu which in the most simplistic sense is a type of calculator
Asus fan boy here, Extremely biased after switching from 5yo laptop to threadripper 3970 + ASUS dual OC rtx-3070 + ASUS prime trx-40 desktop. Logical me: "I know any desktop probably would have blown me away just as much" Emotional me: "ASUS ASUS ASUS" There manuals are great, they have a site where you can register your parts and check for updates all at once, and if you plotted 3070 computing power vs volume I think the ASUS dual would be in the top right.
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...
I added a bunch of SMD caps to the back of a HD 6350 core. After I did, there was an unusually low resistance from vCore to ground, lower than the core itself. Since I had taken the card to 1.8v on ambient already I just connected a AA cell across vCore. The cap started smoking, I knocked it off, and the short was gone :)
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.
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.
@Ben T. Not literally, but close enough. The fact that they told their board partners to start designing and manufacturing PCBs for a 384-bit bus ($$$) means they axed the product too late.
@Ben T. Practically no, theoretically maybe. If the memory controller has not been efused or laser cut, then what you would need to do is solder on the BGA memory chips, and somehow find or make a new VBIOS for the card. The latter part would be extremely difficult.
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.
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.
there are no schematics to read so it's mostly experience and trial and error and knowing how each component generally works. There is a method to his madness because he has revived many a gpu and i might do the same with my failed 290x. seeing him trying to revive a motherboard in the other hand was painfull. I would not take the job
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.
@Ben T. The voltages were measured while the card was running. At first I measured resistance and found that there were no shorts so measuring voltage was the next step.
@Ben T. tbh I don't even know where to begin as I'm not an electronics engineer nor I have any know how's to access schematics for this let alone read it properly I'm just going to see give it the heat gun treatment and see what happens. Perhaps if I can find a place locally to take a look at it or just send it to Buildzoid so he can play with it. I just googled stuff about dead R9 290X's and found how people read the PCB with a multimeter and followed there.
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
if they are working then no need. if they are not working then you are mostly safe stabbing them with a multimeter to read voltage or resistance. Do it outside of the system and when you are grounded. who knows maybe you learn something. just don't short anything or knock a component off the board

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
really depends on the GPUs you want to send. Also working cards are in a way less intresting than dead ones.
@@ActuallyHardcoreOverclocking Thank you for you message
You can put gpus in the toaster? Nice
Depending in the GPU, you may be able to use a dual GPU AS a toaster.
Using a dual GPU set-up as a toaster to reflow the solder on a third card.
@@tomhsia4354 lol crossfire the toaster
don't forget to sprinkle some more cheese on top
Very interesting
what is quid?
Money, dollar

WD = Water Damage
You shouldn't stab your GPU's.
if they are working then no need. if they are not working then you are mostly safe stabbing them with a multimeter to read voltage or resistance. Do it outside of the system and when you are grounded. who knows maybe you learn something. just don't short anything or knock a component off the board
@@Corei14 I understand if it didnt come off as a joke :3 I did forget the indicators after all.
@@Kojiro3210 You were fine. I mean, read his name. That will tell you a lot about him :P
My gpu doesn't work, I know I'll just put it in the oven then heat gun it, that will magically make it work

its last resort. he said multiple times in many videos and many people say the same thing but if you just want to bake it then go ahead
Yeah, if there was no attempt at repairing, you might be frying the die of a perfectly repairable GPU
One day we'll get a chance to see the magic bz repair toaster.
