Why your GPU will fail sooner than others ?

Hello, internet. We have two 2080 Turbo Blower cards from Gigabyte. Uh,

that's at least that's what I thought when customers sent these over to me.

Turns out one's a 2080 Ti, so who cares?

We'll fix them both. Um, this one's reporting errors on two chips side by side. Don't know why. We'll have a look

side. Don't know why. We'll have a look around. My guess maybe something knocked

around. My guess maybe something knocked off on the back or maybe board twisted ripped pads or what not. Who cares? Uh,

this one's uh completely dead. no

detect. Um because we have damage in here. So if we were to power the board,

here. So if we were to power the board, I kind of wonder what's going to happen.

I already tried to boot because he said artifacting. So we're pulling 1.4 amp.

artifacting. So we're pulling 1.4 amp.

Uh so that's good. That means the card is powered, but there is no detect and uh I've already looked on the card

and I saw I saw this very little damage. Easily

repairable. All we need is a proper flux. I'm going to be using Mechanic uh

flux. I'm going to be using Mechanic uh UV559. I've tried this flux to do micro

UV559. I've tried this flux to do micro soldering instead of a crack. And it

actually worked to my surprise. Very

interesting. So, we're going to need an end gate somewhere. And uh I'm guessing we might need a resistor as well. Hard

to say. Most likely it's either a resistor on the bottom or a capacitor.

Who knows? We'll check. We can look at a donor board or we can look at the board view. So, let's see if um I'm not sure

view. So, let's see if um I'm not sure if we're going to need to solder anything on the top, but the U get is definitely need to be replaced or soldered rather placed rather than

replaced cuz it's not there. So, as you can see, that flux wiped wiped out pretty good. I I also tried it to

pretty good. I I also tried it to reball, but it didn't work. Who cares?

Let's do this. Let's wipe that out. And

uh I'm trying to get this thing fixed without taking that apart. Hopefully

that worked. And uh hopefully I will not have to blow air on this thing. That's

why I cleaned the pad so that way I would not have to take away the uh plastic shroud. That's right. The shroud

plastic shroud. That's right. The shroud

here is plastic and I do not want to deal with it. So, but I could cover it up and uh do it that way. So, for now, let's just try to solder this little guy

one pin at a time. We might have issues with ground. I don't know. We'll see.

with ground. I don't know. We'll see.

So, the input one, input two. The ground

felt okay. Then we got this here, this here, and then we're kind of wondering about these two pads. So, let's go look at any kind of board view that matches

closely. So, some kind of a board view

closely. So, some kind of a board view here that doesn't look anything like it, but we do have this uh U gate logic that we're interested in. And it suggests a

10 koohm resistor. And I will believe that if one of these pads is connecting to the middle pin as well as this one connects to the 1.8 volt or the voltage

in for this guy basically to confirm that we're going to need to see. I think

that's true. Yeah, I think that's what it is. So, we're going to have to check

it is. So, we're going to have to check and see if this connects to here.

Correct. And if this connects to here, correct. So, it's going to be 10k. Here

correct. So, it's going to be 10k. Here

we go. 10k is the most common resistor ever. So, be sure to get hundreds of

ever. So, be sure to get hundreds of these. So, let's go and solder that

these. So, let's go and solder that down. Using them tweezers like this.

down. Using them tweezers like this.

Maybe add a little bit more solder on this end. Looks a little dry. Maybe see

this end. Looks a little dry. Maybe see

if we can do it this way. Can't. I think

I mean it looks good, but I want that resistor to float to kind of flow a little bit on the board there. That's

what I wanted to see. All right, let's wipe this off and uh try to boot the cord. See if it posts. I don't think

cord. See if it posts. I don't think we're missing anything else, though. We

could look around and see if anything else is knocked off. Uh there could be memory errors, too. So, we just need to run the card first and see. Don't know

if uh there are any more components that I don't think anything else needed to be populated on the top of that U gate, but who knows? We'll see. So, 1280 Ti.

who knows? We'll see. So, 1280 Ti.

If it posts, we're going to go straight into the memory so we can run the test.

Make sure there's no secondary problems and uh which I'm sure there will be such as need new paste and the card is posting. Perfect. One card is fixed

posting. Perfect. One card is fixed almost. Need to make sure that we don't

almost. Need to make sure that we don't have any errors on the memory and then run some tests. Make sure it's not overheating, which most likely it probably will cuz it's kind of old. So,

let's see. We're going to go two and three. Two, three. And uh let's Oh,

three. Two, three. And uh let's Oh, that looks beautiful. Holy cow.

Jeez. I have never seen anything like that before. Um, makes me wonder if

that before. Um, makes me wonder if there are any more resistors that are knocked off or the card was tossed around, played football with, and now it's got damaged core. Hard to say. We

will see. More than one chip, serious problems. One chip, eh, small problem.

All right. And we're almost there. Two

chips. Uh, two adjacent chips. Most

likely small problem. So A1 B 0. Let me

note that on my notepad. No detect. Uate

ripped off. Uate replaced. Errors

on a 1B zero. Perfect. All right. Shut

this thing down and uh we can probably have a look around in the general area of those chips which will be A1. A1 A

A1. Wait, what did I say? A1 B 0. Oh,

that's not good. So, the A1's going to be here and the B 0 is going to be here.

So, these two chips are 300 mi away from each other, which means that the damage is not there are no ripped off components or anything. That means that the damage is actually we actually need

to redo these chips. Most likely

Samsung. So, let's take the thing apart, see uh what's under there, and uh get those chips either reballed or replaced.

Probably Samsung. Wow, I am shocked.

We have Samsung here. Wow. And we have these pads that still have a film attached to them. Why is that? Why? What

these pads do and why they have film?

Let's remove the film. So, with the film. Oh, this must be some kind of a

film. Oh, this must be some kind of a Wi-Fi wireless heat transfer film. I

don't know. Who cares? And uh one more here. Yes. See, that's special film. I'm

here. Yes. See, that's special film. I'm

not exactly sure what brand. Who cares?

We're going to That's probably what the brand is. So, we'll try to reuse this as

brand is. So, we'll try to reuse this as much as possible. And uh I got a feeling that this this uh pad not even supposed to be here to begin with. I do not

recall seeing that here in my uh 2080 Ti DIY repaste manual, but regardless. So,

we get error. We got errors on this chip and this chip. So, either the board was bent like this, which would potentially disconnect the chips from the board

under the core or the chips. Hard to

say, but given the fact that this is Samsung and someone had already opened this card, um I'm going to try I'm going to try to lift these chips, see if I can

find anything under them, and uh and hopefully that's it. Hopefully we won't have to rebol this thing cuz I do not want to be rebing this thing today. I

just simply don't have time. So, let's

do that. See if that helps.

All right, four chips did not survive. I

redone the fifth one just in case. And

I'm back from redesigning my thing. This

is like the ugliest version of it. It's

like a 1.0. I'll be redesigning that. If

anybody knows, this is a Refflow Pro. I

absolutely despise this piece of trash.

terrible design. Software is piece of crap and the whole workflow is just terrible. There's no manual controls.

terrible. There's no manual controls.

You can't just set the temperature to what you want. That is why I'm reusing this mechanic uh heat plate to allow me to set the temperatures super easy and super quick. Something that the

super quick. Something that the developer of this thing is completely neglected and u not listen to my advice to implement a simple temperature

setting interface. So, uh I will be

setting interface. So, uh I will be implementing the this uh connector here.

That's going to be like one connector, two connector that's going to uh accept um temperature probe like this. So,

that's going to go, you know, in here and then that's going to go into your microwave or whatever, what have you.

Then the switch is going to select. I'm

going to have this one here. This one's

going to stay on the left. And this

switch is basically going to uh change which of the unit are connected to which of the probes because otherwise there will be reading uh conflicts between the two units cuz I cannot connect them in

parallel. So obviously I have to have a

parallel. So obviously I have to have a switch. Uh but they will be both powered

switch. Uh but they will be both powered at the same time. So that's why I need a switch two ports and um this one will have a a separate temperature controller

or monitor rather sitting on top of it like this. And then this one has two

like this. And then this one has two sensors built in. This one only has one sensor that's going to display it here.

And this going to be a second sensor reading. So that's basically what I'm

reading. So that's basically what I'm doing here. Uh and uh let's get back to

doing here. Uh and uh let's get back to this 2080 Ti. No short memory. This is

probably 12. This probably 1.8. I think

we're good. All right, let's plug it in.

Run the memory test and hopefully hopefully it's fixed.

Once again, Samsung has given us problems. No surprise there. It always

doesn't. I do not like Samsung, but at the same time, I like it because it's cheaper to replace a Samsung chip or however many there are that broke their

pads than it is to replace, say, oh, forgot to plug in the uh USB cable, then it is to replace the board. So Micron

will rip the pads off the board whereas Samsung will lose its own pads. However,

you have to consider the amount of force required for the Micron to rip the pads off the board is quite significant.

Whereas Samsung to lose its pads is very little. You can literally fart on your

little. You can literally fart on your graphics card and the Samsung's going to be shedding its pad. So, in that regard, Samsung car card cards with Samsung memory are much more fragile, are going

to break a lot sooner because people can't handle graphics cards gently enough, but it is what it is. All right,

let's uh What are we doing here? Yes.

Okay, so that looks a lot more healthier now. And also on the bright side of the

now. And also on the bright side of the Samsung is that even though there are hundreds of RIP pads, the core might still be okay. But I'm going to have to put it together, run some tests, hot and

cold, just to make sure that everything's great, you know. So, uh,

but as far as that goes, we're done with the 2080 Ti. I'll be testing that later.

Make sure that the there are, uh, no micro cracks would manifest themselves under the core as a result of heat cycles when we're going hot, where we're

going from hot to cold, cold to hot, etc. And, uh, we're done here uh, almost. And uh and since it's already

almost. And uh and since it's already late, I probably going to do this one tomorrow. A 2080 some errors on memory.

tomorrow. A 2080 some errors on memory.

Um uh that I always forgot which ones there were. And uh hopefully this was uh

there were. And uh hopefully this was uh educating, maybe entertaining. Um don't

forget to like and subscribe maybe. And

I'll see you later in the next video.

Goodbye.

Another day, another dollar. Actually,

it's the same day. Um, I figured mama's cooking up some soup for tomorrow. And

um, and I'm going to be cooking up some memory chips. This one's a 2080 from the

memory chips. This one's a 2080 from the same customer, Gigabyte, with the exact same problem. Um, Samsung is what the

same problem. Um, Samsung is what the problem is. These two chips reporting

problem is. These two chips reporting errors. The strange thing about this is

errors. The strange thing about this is that normally it's either the corner chips or one's on the bottom here, but none of them are at the bottom. And uh I

don't know how that could have happened to be honest. I don't see any signs of damage. There's no broken traces or

damage. There's no broken traces or anything. Uh unless something fell down

anything. Uh unless something fell down in here. Uh no missing capacitors or

in here. Uh no missing capacitors or none of that. The one funny thing though, let me go ahead and show you what is so funny about this particular

card is that it's got two fuses soldered for double the power. Right there.

That's how you get double the power. If

one fuse isn't enough, put it just to put in a second fuse. So, this is like a shunt mod basically is what this is. So,

let's fix that with some uh whiskey tango. Put a comment below if you know

tango. Put a comment below if you know what I mean. I have some whiskey tango smells really good. I love that stuff.

And let's remove this Sean mod. Not

exactly sure why he put that there. Um

maybe this one blown and he couldn't remove it. So, we're just going to do

remove it. So, we're just going to do this and then put that one there. The uh

replacement that was on top of it. All

right. clean it up and go for a rebal before we go anywhere. Actually, I need to make sure that this fuse is actually good. So, who knows what people solder

good. So, who knows what people solder on their boards. This fuse is good. Or

at the very least, in theory, who knows how it will handle the load. We're going

to find out one way or another during the testing. And here comes the time for

the testing. And here comes the time for the preheater. And uh if you watched

the preheater. And uh if you watched Alex's uh last video about the connector replacement, the connector replacement

guru, he said you do not need a preheater or the oscilloscope to repair consumer electronics. So, we are not

consumer electronics. So, we are not going to be using the preheater today as you can see because graphics cards are

not consumer electronics, let alone motherboard with so many damaged sockets that replacing a socket can be done with

a simple hot air station like this one.

This hard air gun, just give it 600° and you'll be good to go. Or at least that's according to him.

I'm kidding. He never said that. But he

implied so whiskey tango first revision.

This stuff smells good, but it is not for BGA. No sir. This thing's going to

for BGA. No sir. This thing's going to boil. It's going to foam.

boil. It's going to foam.

It's going to it's going to smell nice.

I like that. Uh but it sucks for BGA. I

can solder the chip on the board using that flux, no problem. But I just cannot rebol anything with it. I mean, you can solder anything to the board with just spitting on the board. As long as

there's some kind of liquid that provides some kind of acidity between the solder ball and the pad, you can solder the BGA. So, the flux can be the

cheapest locks possible. You can even scrape some of the resin off of the tree in your backyard if you have that kind of tree growing out there, you know, or whatever, and it'll do just fine. But

where it comes to sticking to the surface, you know, all these other properties that flocks offers you, you know, it's not evaporating as quick or, you know, it's got gives you a little

bit of flow, you know, viscosity, surface tension, all that good stuff.

Obviously, flux is a winner. And that

sap that off the tree will probably not give it to you, you know. And this stuff smells really nice. I like the way it smells. I can just sit here and just go,

smells. I can just sit here and just go, "Oh, yes, that smells good." I don't know. I'm just kind of hallucinating at

know. I'm just kind of hallucinating at some point sitting and sitting around just kind of the brain just clicks and I start smelling that smell. I don't know.

It maybe it's just me, but just like out of nowhere, no one around me smells like this and I just start smelling that and it just reminds me and just wants me and

it just forces me to go back and do some soldering. And that's what we're going

soldering. And that's what we're going to do here today. We're going to be doing some soldering them balls. And I'm

guessing what are these? 14s or 16s? Uh

HC HC16. Yes. Good. As a matter of fact,

HC16. Yes. Good. As a matter of fact, let me show you. These are indeed HC16.

Here's my anti-glare lens.

Yeah. See,

no need for any kind of anti-glare light. All you need is an anti-glare

light. All you need is an anti-glare lens. That's right. North Ridge fix. My

lens. That's right. North Ridge fix. My

solution cost me 10 bucks versus 110s, but whatever. I'm not a businessman. So,

but whatever. I'm not a businessman. So,

by the way, if anybody's interested, I do have a video about this. It's titled

something along the lines of turn your 600 microscope into a 6,000 microscope or something like that. Yeah. So, we're

going to wait for the board to warm up.

I will lift these two chips. And I'm

guessing we're getting screwed by Samsung again. That's why I have a whole

Samsung again. That's why I have a whole bin of them here and a whole bunch of these chips. So, we're probably going to

these chips. So, we're probably going to end up replacing them. And if I'll see any of them ripped pads on these two chips, I will lift the adjacent chips as

well for inspection. Just like I did with the previous card, just to be safe.

And hopefully, just like with the previous card, no rebing of the cord is necessary. Not that it scares me by any

necessary. Not that it scares me by any means. cuz I can reball at least 20

means. cuz I can reball at least 20 times a day and not get bored. I'll get

tired and exhausted and depressed.

Probably won't sleep at night hallucinating about the reballs and all that kind of stuff, but it's not going to hurt me. At least not on the outside.

Who cares? All right, let's get these two replaced. See what happens. Speaking

two replaced. See what happens. Speaking

of 1590s founders editions, look what I got. Let me show you what I got.

got. Let me show you what I got.

Do you see what I see?

This is a socket I believe that I think should fit I don't know uh

1590 founders edition board. Uh if it does then I'm going to have to find a male end for this. And the problem with these damaged sockets is fixed. all of

them customers that are going to Alex and him crying about the lack of parts may actually not be as bad. Um, but I

will not know 100% until I get a Founders Edition 5090 um on my bench. I

did have two, I think, um, but I ended up fixing them without replacing anything. So, eh, better luck next time,

anything. So, eh, better luck next time, I guess. Here's the uh packaging from

I guess. Here's the uh packaging from the DG key where I got that connector so you can figure out the mail end for this. Let me know part number,

this. Let me know part number, manufacturer number, all that kind of stuff. That's the connector I got.

stuff. That's the connector I got.

That's the one that looked closest. So,

and it wasn't even that expensive. I

think it was like 10 bucks or something plus shipping, six bucks, whatever.

So, that's a little sketchy. Uh, none of the chips that I removed have any rip pads. At least it doesn't look like they

pads. At least it doesn't look like they have. So, uh, what's sketchy about that

have. So, uh, what's sketchy about that is that normally you do not get errors on two different chips side by side, unless there are issues under the core with a solder crack and whatnot. Um, or

some resistor that connects both chips went bad. Uh, ZDC or something like

went bad. Uh, ZDC or something like that. I don't remember the name of that

that. I don't remember the name of that resistor or the signal, whatever you want to call it, that connects two chips. Um I'm also guessing it could

chips. Um I'm also guessing it could have disconnected from the chip in that particular area and then interfering with the other chip as a result. Uh

there could be basically many uh ways to explain the errors on uh two chips at the same time and I didn't see the need to remove the adjacent ones. So let's

just go and check for short real quick.

Make sure there's no short and run some tests. So 13 ohms USBC 1.8 8x 1.8's

tests. So 13 ohms USBC 1.8 8x 1.8's here, I think. Or this five or here. Who

cares? All the same. All right, the card did post before, so it'll post now.

We're going to go straight into the memory and see if the test passed. And

if it does, we are done. Or at the very least, in theory, if it posts, then the chips just gone bad. Or or maybe they just needed to be reflown. I I don't

know. It's I I would prefer to throw

know. It's I I would prefer to throw them away and not second guess. So that

way I do not solder them onto another board and then start chasing those for 2 days. That happened to me several times.

days. That happened to me several times.

I do not want to do that again. So two

and three. Let's see if that runs. Oh,

we getting artifacts. Okay, so that's good. But where are we getting the

good. But where are we getting the artifacts at? Let's wait and see. It'd

artifacts at? Let's wait and see. It'd

be interesting if the artifacts are at the adjacent chips now. That would mean we could just refflow the other chips or rebol them or whatever. Uh, nope. B1C0.

Very interesting. Let's shut this thing down. So, the chips that we have are

down. So, the chips that we have are good. I'm not going to throw them away.

good. I'm not going to throw them away.

Put them aside. We'll probably reuse them somewhere else. Now, what could possibly be the problem? Did the owner throw something under the core? Let's

have a look. See if we can Oh, there's a lot of dirt in there for sure. And I'm

guessing that's the source of our problem. Look at all that dirt under the

problem. Look at all that dirt under the core. It's clean under the memory. Oh,

core. It's clean under the memory. Oh,

more or less. But under the core, holy cow, there's a lot of dirt. I'm worried

about it being a reflow of some sort.

But no, it doesn't look like it. Just

looks dirty. So, I guess we're going to have to do a rebolt today after all, which sucks. But it's okay. I got

which sucks. But it's okay. I got

nothing better to do anyway. So, let's

go and reball this core real quick. And

uh hopefully that helps.

Okay, Rebball is done. Let's plug this thing in and go straight into the memory test without measuring the resistances or powering it on in a controlled manner. We don't care if it blows up,

manner. We don't care if it blows up, right? That's right. I'm kidding. I

right? That's right. I'm kidding. I

already checked. Everything's already

good. We just need to see if it's still posts still. Let's see. What do we got?

posts still. Let's see. What do we got?

Nothing. The screen is black. Perfect.

Okay. What could have possibly gone wrong? I don't know. Maybe connections.

wrong? I don't know. Maybe connections.

I will check for PEX. I've had voltages, but I did not check for all of them. So,

I think PEX is here. Where's PEX? Here.

So, do we get PEX? Yes, we got memory and we got core. Yes. So, we got everything, but it's not not detecting.

We have a we have a no detect situation.

Very interesting. Why is that? I wonder

if the silicone had gone under the pads, preventing them from adhering to the solder blob that we put on the board.

That could happen. That stuff is nasty.

So, all the data lines are good. Um,

what else could possibly go wrong here?

Um the let's check let's check for the obvious. So first data we've checked

obvious. So first data we've checked that already. Yes. Yes. Block is good.

that already. Yes. Yes. Block is good.

And the PEX reset is there. So we're

good there. Let's uh make sure that I think this is the PEX reset logic here.

No. Where is it then? It's not here. Is

it going in here? Why? Why are you not reaching? Looks like it would be here.

reaching? Looks like it would be here.

Why isn't it? No idea. Let's look around the board. I'm failing to understand

the board. I'm failing to understand where does Pex reset go. Okay, so it's supposed to go Okay, so it goes south.

Never mind. I thought it went here. So

this trace goes here and then it goes here and then it goes and then it goes south basically. Yeah, I have no idea

south basically. Yeah, I have no idea where that goes. Probably goes on the front of the board maybe. Uh we could probably check pretty much any U gate at this point. Not here either. Not here.

this point. Not here either. Not here.

None of that. Huh. Interesting. Probably

front. The uh that gate's probably here.

I wonder if it's this one here or something else. I have no idea. Um, so

something else. I have no idea. Um, so

what is happening? Let's uh let's uh wipe the pads here, contacts, and we're going to try and run the cord as a secondary and see if we are at the very

least detecting it and uh run the memory test if we do. Very interesting problem that we're having right now, I must admit. So, let's go into the memory test

admit. So, let's go into the memory test and going to go in here. Who knows?

Maybe the cord was dead and we finished it off. I do not know. LSPCI. The card

it off. I do not know. LSPCI. The card

is detected. Perfect. It just refuses to pull. Still, we're going to go two,

pull. Still, we're going to go two, three. That's going to take a while.

three. That's going to take a while.

We're not going to see anything on the screen cuz yeah, it's not testing it because the card is a secondary. But

let's shut down. So, if the card is detected, it should post. But somehow

we're not getting anything out the display. So, maybe oxidation after a

display. So, maybe oxidation after a heat cycle inside the uh HDMI port.

Let's try that. See if that works. That

actually does happen quite a bit.

Everything seems normal, but it does not post. So, let's see if it posts now.

post. So, let's see if it posts now.

There we go. Yeah, just a oxidation inside the port. So, perfect. See, you

learned something today. Let's go into memory and run the test. Hopefully, we

get a pass. Hopefully, it was just that silicone that made its way onto the core, that dirt. And it looks like it isn't.

This is not looking good already. So,

but who knows? It looks different though. I guess we have a resistor

though. I guess we have a resistor problem or something. Or maybe we have a dead core. Who knows? There's only one

dead core. Who knows? There's only one way to figure this out would be to check the resistors one by one. And if they all check out, then the core is toast.

So that's going to take a little bit of time, but whatever. Yep. Exact same

chips, exact same errors. T uh B1 and C 0. Uh unless I'm losing my mind here. So

0. Uh unless I'm losing my mind here. So

let's uh close this. B1 C 0. I'm

probably losing my mind here. So A, B, that's B1. That's B1. and C 0. Oh, wait.

that's B1. That's B1. and C 0. Oh, wait.

What did I uh see what happens when I do recording?

I screw up. So, yeah. C C1. No, wait. We

had errors on C1. This is the chip.

Where's the other chip? And uh and B 0.

Yeah. Okay. So, we Oh, so it all checks out. So, we had errors on these chips.

out. So, we had errors on these chips.

Right now, we have errors on these chips. So, we just need to reball these

chips. So, we just need to reball these two chips cuz we didn't have errors on them. Uh, so what I'm going to do is I

them. Uh, so what I'm going to do is I kind of want to try these chips. And uh

so that way I don't have to charge the customer for any chips. And uh that's great. That's great news. It means we're

great. That's great news. It means we're getting somewhere. We're just not

getting somewhere. We're just not getting there the way we want to, but we're getting there. And uh it's okay.

It's Friday. Doesn't matter if we take a little longer than we wanted to. I mean,

it's it's what it's um almost 1:00 in the morning, so that counts as Friday.

So, let's uh reblow these two chips and solder them in places of these two. That

way, nobody gets mad. Customer had to pay for four chips for the other card.

But this time, we're going to do everything we can so that we can reliably fix it. And I'm guessing we didn't even have to rebol the core. We

just needed to rebol the chips. And if I wasn't recording and talking gibberish all day, I would have noticed the problem and would not have done what I've already done. But then you wouldn't have anything to watch. So, it's a win

for both of us. That goes on. Balls go

in. Shake them. Shake them. Pour them

out. Take them out. Put it there. Heat

it up. That's it. So, that goes there.

Let's uh give these balls a heat treatment. Anti-glare light off.

treatment. Anti-glare light off.

Anti-glare light on. Anti-glare light

off. Anti-glare light on. Not a light, just a lens. Yeah. $10 lens. And the

glare is gone. Look at this. Look at

these chips. You see stuff that you haven't seen before. There. Amazing.

Look at this. What more do you want? Can

I get a like for this? Come on. Just a

couple more degrees. There we go. Looks

beautiful. This looks beautiful, man.

All right. Let's put this thing on a preheater and uh replace these chips real quick. Being careful, of course, we

real quick. Being careful, of course, we do not want to overheat the original chips because we plan on reusing them.

That's right. So that way we do not need to charge the customer for chips. If

anybody cares, the nano No, it's not a nano. Nano is this. Where's nano? This

nano. Nano is this. Where's nano? This

is nano here. Yeah, this is a 559 mechanic. And this is nano mechanic. Um,

mechanic. And this is nano mechanic. Um,

this is good for micro soldering like crack repairs. I've already said before,

crack repairs. I've already said before, not good for this stuff because it likes to foam. It's foaming up. It's not

to foam. It's foaming up. It's not

boiling. It's just kind of foaming a little bit. Uh which is annoying and it

little bit. Uh which is annoying and it doesn't want to flow under the the core.

So, I'm not going to be using that for this kind of stuff. Uh it's not foaming anywhere near as bad as the Blackbeard stuff. Uh but this stuff just smells so

stuff. Uh but this stuff just smells so good. You're just tempted to use it no

good. You're just tempted to use it no matter what. Even if it's boiling like

matter what. Even if it's boiling like crazy and foaming, I don't care. I just

want to sniff that stuff. So good. I

don't care what anybody says. I like

this stuff. It smells really nice. So,

and he promised me a free life supply of flux. So, yep. I'll be getting that. No,

flux. So, yep. I'll be getting that. No,

I'm kidding. I'm not going to be getting I'm not going to be making him give me a life supply. Uh, a flux. You kidding me?

life supply. Uh, a flux. You kidding me?

I don't want anything for free. You get

stuff for free. You don't value it. You

want to enjoy something in life. Doesn't

matter what it is. It's a car, your health, your home, your relationship, whatever it is. If you didn't pay for it, you will not value it. Cuz you only value things by the uh almost

proportionate to the amount of price you paid for it. Whatever the currency may have been, your blood, your sweat, your tears, your money, you know, whatever sacrifice. So now I lost track of what I

sacrifice. So now I lost track of what I was saying. I was giving you some kind

was saying. I was giving you some kind of a wisdom lesson of the day.

Who cares? You see this? all that's

boiling. It's not so much boiling, it's just foaming. And uh that foaming kind

just foaming. And uh that foaming kind of blinds me sort of when I do stuff.

When I try to solder, let's say I'm trying to solder the edges of the driver MOSFET here and I can't see the pins. If

that stuff is just foaming and when it's fresh, what once it boils out, it's fine. But it's just, you know, something

fine. But it's just, you know, something annoying sometimes. But it smells really

annoying sometimes. But it smells really good, though. I'll be paying for it. He

good, though. I'll be paying for it. He

sent me like um three at least three if not four free syringes. Two of them I throw away cuz they they just harden.

Can't use them with a needle and they even become hard inside of the syringe.

You can't even squeeze them out just like next day it's done. Can't squeeze

out of the syringe cuz it's a bad blend.

But he he got the blend fixed uh figured out I suppose. At least that's what he said in his videos. We're talking black horse here. So he's constantly improving

horse here. So he's constantly improving his formula and hopefully he'll narrow it down. All right, the chip is out. No

it down. All right, the chip is out. No

rip pads from what I can tell, at least on this one. Let's see if uh we get lucky with this one as well. And no

ripped pads. Perfect. So, let's prep these. Solder the other chips back on.

these. Solder the other chips back on.

And hopefully everything should work.

Easy clean up. Wipe it off and you're done. Same for when it's cold. Just wipe

done. Same for when it's cold. Just wipe

it out with alcohol and it's super easy to clean. I like the way it dissolves.

to clean. I like the way it dissolves.

So, but we're not going to use it to solder the chips down because all that boiling. We're going to be using my good

boiling. We're going to be using my good old trusty Skiri V2. If anything, I would recommend not using V2 because

it's thick. Just go straight to V3. Uh

it's thick. Just go straight to V3. Uh

V3 is a lot easier to apply. It's

thinner, but it behaves exactly the same way. So, there's really no need to buy

way. So, there's really no need to buy the old V2 anymore, and it's a lot easier to just work with the V3. The V4

was even more thinner if if not the same as V3. Um, but I think it started

as V3. Um, but I think it started degrading, started becoming worse, uh, for whatever reason. I'm not exactly sure. Uh, but everything else seems to

sure. Uh, but everything else seems to be the same. Um, and their newest V5, that was a completely different flux. It

just it looks completely different. It

behaves different. It just and it's just disaster. I don't know. It was it was

disaster. I don't know. It was it was the worst of them all. So, but I'm using it only for soldering the BGA chips down. That's the only use case for that

down. That's the only use case for that flux because it gives me that perfect uh acidity that I need to achieve during

the activation phase and it cleans in the ultrasonic very easily. So, just the two things that I was interested in, it delivers. Everything else, not so much.

delivers. Everything else, not so much.

So, let's solder this one down. That

one's done. And this one is done.

Hopefully, we won't have to reball any more chips. There we go. So, these two

more chips. There we go. So, these two chips work, then they have not suffered any damage from before, which would be a good thing. And uh I am sure that the

good thing. And uh I am sure that the other two work because they worked before. So, I'll probably be repurposing

before. So, I'll probably be repurposing them for a next repair. All right, let's go into the test and see if the other two chips are good. And hopefully I can

go to sleep tonight. That will be nice.

Already after 1:00 in the morning. Did I

press No, I did not. Oop, I did not press F8. Oops. Got to restart. Dang it.

press F8. Oops. Got to restart. Dang it.

Okay, let's try again. Got distracted.

Come on, hurry up. I'm getting old.

There we go. Let's run them mats. Two,

three, and hopefully this time it'll be clean. Looks good so far. We don't see

clean. Looks good so far. We don't see any funny squares that we've seen before at the very beginning of the test. So, I

think we're going to get a pass there.

We got a pass. Short is gone. That's

right. I said it. Sue me. Anyway, I'll

put this thing together, run all the usual tests. Hopefully, everything goes

usual tests. Hopefully, everything goes well. It should. And uh thank you for

well. It should. And uh thank you for watching again and thank you for sticking around all the way to the end.

All right, no sleep today. Looks like

the uh firmware doesn't want to run.

We're going to try again. Yep, there we go. Did you see that? I saw what I did

go. Did you see that? I saw what I did not want to see. Let's wait for this thing to close. We're going to close this. We're going to close that. We're

this. We're going to close that. We're

going to close that. The hide firmwork.

I saw nothing good. I saw that we wasted our time big time. Or we potentially need to rebold the rest of the chips, which is highly unlikely. So, let's see.

I'm trying to run this there and it seems to be stuck. So there we go. Where

is for mark? Firmark is still there.

Let's close this. And yep, there we go.

I wonder if running a memory test would show us anything interesting. I highly

doubt it, but who know? We're going to run mats and then we're going to run NVMT and analyze the results. I hope we get artifacts while running Matt so that way we know that there's a fault chip.

But I see nothing on the screen. We

completely blacked out. Did I run the wrong test? I don't think so. So, let's

wrong test? I don't think so. So, let's

go ahead and do a blind shutdown. I'm

starting to think we need to rebolt the rest of the chips. All right, let's boot one more time and repeat just in case I did something wrong. Ah, dang. That

stupid fan just cut my finger. I was

holding it down, let it go for a second, and it just shaved my finger out. Ouch.

That hurts. So, two and three. Yeah,

that's what we wanted to do. We wanted

mats. Man, that fan is strong and it hurt me bad. Gigabyte. I think Matt's going to pass. Yeah, Matt's pass. What

about the NVMT? Let's look at the NVMT.

I don't see anything that I want to see.

D1. So, possibly issues with the D1. So,

that's probably worth looking at. Yeah.

So, D0, D1. So, we're going to look at those two adjacent chips. Uh, let's uh let's run mass one more time. That

stupid fan almost cut off my finger. But

I'll do that tomorrow because right now I'm it's already late. I need to go get some sleep and my head hurts too. So

let's close this down. So both of the uh D chips we probably going to need the rebal unless something else went wrong.

My finger is not bleeding but it's kind of like a paper cut.

All right, no more errors on the NVMG.

Hopefully everything will work. Oh, I am seeing geometric distortions on that donut. Close this. Close this. Close

donut. Close this. Close this. Close

this. See if I can run this. Yeah, see

this. See all these little dots? That's

a dead core. And yeah, that's what dead core looks like, ladies and gentlemen.

All that flashes, freezing and crashes.

The timer is still going. Come on. Yep.

Uh, we can try to run something else.

Everything is freezing. Everything is

just kind of failing to unload, which is normal. But we can probably run uh super

normal. But we can probably run uh super position is probably not going to run.

See, there you go. What was this? Yep.

All these little tiny little pixels on the screen that you see. That's a dead core. Very unfortunate. See if we can

core. Very unfortunate. See if we can run a smaller resolution. That's so sad.

So much work. 2:00 in the morning and here we are with a dead core. Yep, there

we go. Oh, there are the aliens.

I was waiting for these aliens to show up. Perfect. Okay, shut down. Have a

up. Perfect. Okay, shut down. Have a

good day. Thank you for watching.

Hopefully, this was entertaining or educating. If you see these aliens and

educating. If you see these aliens and you have Samsung or Micron, well, Micron, it would be the Micron from 2018. But if you if you got Samsung or

2018. But if you if you got Samsung or and you see ali aliens like this on a 2080 or 2080 Ti, it's done. Goodbye.
