God oh this is really bad oh this is
terrible wait what there's no way this is okay what why is this
on I just got six gpus for only
$1,700 because they're all dead although by the end of this video with any luck a
couple of them will be alive and huge thanks to origin PC for sponsoring this
the gpus we have here go from boots up but crashes
to I haven't looked at this one yet so
let's have a gander brand in boxes seen better days okay it's just a loose
graphics card excellent oh water we also
have um a variety of loose screws that's
never a good sign if you want to do what we did and go on ebay.com and just get
it for parts GPU make sure someone else hasn't already had a crack edit like
this one right here it looks pretty decent and as far as I can tell from the
description the old owner didn't really put a whole lot of effort into trying to
fix it as for like this one it's clearly
already been used for a parts card um if we get this guy back I will be shocked
980 TI for 10 and a couple bucks worth a
try first step when you have a dead GPU is to verify that it's dead in order to
do that we have our our test bench here from origin it's their Millennium 5000t
and it is certifiably a good one I guess we should probably make sure this works
first Brandon oh fancy so in here we have all
of the best stuff so 12900 K 3080 TI
good looking board from MSI and a
peel wow the best feel in a while yeah that was a really good peel I have to
say one thing that's super cool about these PCS is that even though it you
know comes with a warranty you can swap out the parts and you still maintain
that warranty I don't know if they intended you to put something like this
in it but we're going to test it out well the rest of these gpus we just got
from eBay this one right here is jonos yep so what's wrong with it it would
kind of like disconnect like the monor would just disconnect randomly and it'll
do that in a series and stop and it'll
do it in the series again so it like happen like every couple hours so I'm
kind of hoping you can fix it or see at least what's wrong with it that sounds
very hard to diagnose I don't
know also I've just been running firm mark on this PC and it's looking great
gpus is at 70° everything's kind of in line with what I would expect yeah the
memory is kind of hot it's at 94° but that's not too crazy NVIDIA says
you can do 20 so that's a good Baseline to go off of now check jonos in I'm
sorry origin you did actually do quite a nice little job of cable managing here
and I'm going to have to ruin it we have loads of power easily available though
thank you for running it like that origin I don't know Brandon you say it's like their system builder but I've seen
some pretty shoddy stuff from system Builders that's fair but not origin yeah
not origin I think step one for this guy is going to be just to give it a little
clean one thing to note when blowing compressed air make sure that it doesn't
spin your fans it can just overload the motor and turn your fan into a generator
not great there are apparently like diodes and stuff in this that should
prevent it from killing your stuff but either way just don't let them
spin wow that helped a lot brand new if
your GPU seems to be dying try out the easy stuff first make sure your drivers
are up to date and check if your temps are okay so we're just going to be doing
a quick driver install here and then we're going into Hardware info 64 it's a
free program just install it check your stuff run something like maybe a firmar
or something just any game that you run
see if anything in your GPU temperature starts looking weird so temperatures
that you're looking for GPU shouldn't be over about 80 and memory is normally
fine if it's around 100 120 at the
highest what you really want to look for though is that their performance isn't
just tanking so we have something like fir mark here we can run it and we'll
see that at the start we're getting 225 FPS it's going to go down a little bit
at first as the turbo runs out but it shouldn't like become half of that or
just completely fall off a cliff well I have some bad news for jonno he thought
that the temps might have been the problem here and they aren't I didn't
think it would be we could leave this for longer but it's at 50° right now
like there's clearly nothing wrong with the GPU temps one thing that people
almost never do with their gpus is update the firmware on it even though it
can fix things like what jono's been seeing they might have patched it like a
year ago and he's just never updated it we've done everything easy on jono's GPU
so drivers firmware temps are looking
good I can't get it to crash so that's kind of where we're at with that right
now what I'm doing is just running 3D Mark with a GoPro pointed at the screen
to see if it does crash eventually there's so many things that could have
been causing his problems I don't even know where to start like I personally
had a problem that was similar to that a while ago and updating my monitors
firmware fixed it so like there's too
many variables at this point until we see it actually crash and can go through
the logs while it runs though we're going to test out the rest of these gpus
to make sure that they're safe to put in our system and just look for anything
obvious so first thing we're just going to check for shorts it's highly unlikely
that there will be shorts but if there is and you plug it into your computer
you might blow up your power supply so it's cheap and easy Insurance got our
multimeter here it'll go Bing there's a short
like that and we're just going to go across these pins it's going to be
something like this thank you Gamers Nexus so if these guys are shorted to
those ones you're going to have a bad
time uh that one a sense pin it's fine
it's the sort of thing where if your power connectors are shorted your gpus
is probably never going to come back you done when you're getting it off eBay you
might as well check yeah so none of these are going to blow up our power
supply super easy probably don't have to do it but I would recommend doing it if
you have multimeter cuz cheap easy
Insurance oh shut up now what I want to do is just take
these apart put them back together see if there's anything obvious and I find
that a lot of the time just disassembling and reassembling stuff
that's dead is the easiest way to fix it you won't know why you fixed it but it
just does first one we're going to look at is this rx580 and we paid $150 for it
uh what do you think the chance are this was minded on David 100% 100% yeah
probably one thing that I do like about this card is that there is still a
sticker on the back so chances are it hasn't been taken apart and no one's
really taking a look into what's gone wrong with it this one smells kind of
weird like you know how there's those thrift shops that get cool stuff in oh
yeah then there's those ones that just like someone's nand died and her whole
house is there oh no this one smells like that this might be completely
unnecessary it might just work so easy to take it apart and just have a look
there we go okay this card it looks fine now there is just some crud on it
there's like a little bit of corrosion in some spots that's kind of what I like
to see cuz that's the sort of card where if you just give it a clean it might
just come back should give a little wash hell yeah just using a little bit of
Vice alcohol and toothbrush those spots
that are kind of gnarly
just last a little bit for this
580 sorry David if I was going to do this properly
I would also replace the thermal pads but they seem like they're fine and if
it actually works later maybe I'll replace them this card's good to put in
the system but I just want to keep running jono's 2080 TI to see if it
eventually crashes it is entirely possible that we fixed it when we just
blew all of the crap out of it and put it in a case with good air flow so it
might have just been thermal throttling before it's so hard to say our next card
is this GeForce GTX 1080 now I'm a little bit scared about this one because
I had the exact same card in my system and these early ones from EVGA had a bit
of a bad habit of kind of like exploding there's just something wrong with the
capacitors whatever you updated the firmware it was totally fine whoever
owned this might have not and it might have just killed itself let's take it
apart though give it a little clean and then it should be good to put in this
system this one's also just like pretty Gro filed like look I think those are
supposed to be holes but it's just like solid I really miss the days of the
capacitor plague used to be that something was dead you could just take a
look at it one of these guys would be bulging replace it it's all good now
it's so much more difficult even if a capacitor goes it's like one of these
stupid little things and they're super hard to deal with that yeah that really
looks like someone spilled a bunch of water on it well sticking in some rice I
say yep sticker in some rice that's actually really satisfying in a weird
way yeah this is I really have been loving this I am a bit scared for this
one though and this part you can really see just whatever was spilled on this
it's like all sticky up here collecting dust it's even kind of wet like right
there still M
tasty well I think I found what's Dead with this GPU and if we just take a look
uh yeah that's now how rough is this going to be to fix this is a smaller
Phillips and if we look right here it looks like a really large Phillips when
you put it against this chip but yeah I am very confident that this is what is
wrong with this GPU now can we get another one of these
chips I'm not sure but there is one right here and we might have something
that's dead around that has one of those I don't know I found what's wrong with this do
you want to have a little look someone like just extinguish a cigarette on top
of that icy oh there's also like a massive solderable brigina resistor yeah
that seems um do you think that's the culprit or do you think someone tried to
fix it she's had some work done the sticker were still on the GPU so no one
could have had like I don't think anyone took it
apart what the heck's attack oh I was
like this is just disintegrating it possibly caused like a short then scent
whatever this is looks like a mosfet I'm going to say it's a mosfet uh yeah it's
probably it's dead it's dead yeah it's very dead oh yeah you might be able to
get the I markings of the the not dead guy yeah I did oh you and you bought it
I haven't bought it yet okay if it failed short then like replacing it
doesn't matter right cuz it's already shorted duting is bad yeah this is one
bucket of short mate oh jeez have you tried running it I have not I'm going to
turn off this Benchmark of jono's cart it's been running for 3 hours straight
with a stress test and it hasn't failed yet so I think it's safe to say it's
fine or the problem was with jono's system that exploded mosfet that we saw
is shorted so even if we replace it it's
a L doing what it's going to do when it's on anyway well one of the tests that we wanted to do was what if we just
shorted it and see if the card boots up we don't have to take it off to test
that cuz it's already shorted if you wanted to work properly as an actual
like load switch we would replace it so that if it need to turn off it can yeah
the worst thing that could happen has already happened I think that's a that's
a power supply trip man yeah that sounded like a power supply trip to me
that still smells fine send it again yeah
oh oh maybe you just needed the magical
hands man do we have a do we have an output no no well it still is post
coding so like oh yeah maybe it hasn't posted yet I feel like we're in Windows
right now so wait if we're in Windows then yeah then man then we can do stuff
yeah no nothing it's G it's
G knowing what P fets do I Would S I
would assume that it would have to be closed for the graphics card to work so
it is closed permanently not by choice
um so yeah I know I think there might be something else wrong okay so what we're
going to do now is see if we get core voltage this is a Jank way to do it um
there's no there's no AC it's all DC it's all low voltage um one of the
easiest ways to do it is probably the end of one of these um capacitors never
mind I'm getting 12 volts cuz I got it the other the wrong way around but there
you go 12 volts okay we have voltage uh
um well that means the power supply is working wait are you plug to the GP
right now like for display wait what the
display working uh we gain coal voltage it's working wait what yeah it's
working like we got GTX 1080 we co voltage man it works but I have no idea
what we did to make it work and you know what we call that like if it if so we
removed the back plate although wait
there might have been some stuff in there there was some liquid uh yeah have
you tried to replace these yeah because those touch the Caps right is is this
game can you can you do a stress test and do we have a like a thermal camera
to see if this actually gets warm I can get a thermal camera oh oh maybe it's
not so worky she picks you up just to put you down again it's less dead than
before at least so we can potentially take off the back plate look at it with
like a thermal camera or something and see if we can find out some stuff that's
an after lunch problem I'm disa pointed I'm probably going to do most of it off
camera we're going to just move on see if like where did that 580 go see if
this 580 after we cleaned it just works now we have
lights we have
fans interesting I'm suspicious that
it's going to keep doing this one thing that's interesting about this card is it
has a bio switch on it
so no way no way oh wow okay so this is
I didn't want to say what I thought might have happened cuz it's so stupid
but I was a bit suspicious there might have just been a mining BIOS on this
with no video output and you just switch it over to a normal gaming BIOS and it
just boots up uh because we did switch from NVIDIA to
AMD I'm just running ddu getting NVIDIA
drivers off there and then this might work that would be crazy 150 bucks for
580 can you believe it David that's what it should cost yeah that is what it
should cost we'll let it run through but I think
she's good it would be so embarrassing to put up a video on fixing gpus and not
fix one well did we actually just fix this
thing with the flick of a switch maybe hopefully it's not like that stupid 1080
yeah we'll leave it running for a little bit let's see what the next one is which one do you want to do let's do this one
what is that oh this one's bad so this
one's this is a 5700 XT beautiful card
not great things have happened to this one and someone's already had a crack at
fixing it we need to come over the microscope to show you what's on the go here you probably can't see it but on
this pciu Trace there's a little capacitor that's missing right there
also it's all burned to heck up here now
there's kind of two things that I could have happened this cap might have fallen
off card died and whoever tried to
repair it cuz someone's clearly tried to repair this was a big dum dum and put
their soldering iron right here and burned it that's kind of best case
scenario other option this memory chip like destroyed itself and in the process
blew up this cap if that happened she's dead never coming back so in the
microscope you're able to see it it looks like that this might have just
completely blown itself off although more likely someone scratched this off
trying to repair it got a big old ball of solder right there that's definitely
not helping anything that also might have been this cap blew up and in trying
to repair it they ended up just screwing up this one you can also see some solder
on this Trace up here where they presumably tried to you know add some
solder to the trace and Bridge it or whatever now what you might think that
you'd want to do is just attach like a wire there wire there and add a cap but
the problem is that PCI traces are
length matched and very fiddly basically
this capacitor being gone is a huge
problem because there are two traces on each one of these pins and those need to
be the same length within I looked it up and I think for Gen 3 it's like 5,000 of
an inch or something stupid like that that's just because the signal is
switching so incredibly fast that if one
of them takes longer than the other the whole thing just kind of falls apart I'd
like to say that I have a good fix for this but I have a really dumb fix for
this that might work well that was a success this 580 seems to be working
great it's pretty much raid on what we'd expect for a 3D Mark score this card has
16 PCI lanes and the very last one is the one that's blown up no if we just
put it in an adex slot and don't use
these ones maybe it'll work let's try it well
this slot right here is adx as you can see there's only pins up to there
nothing at all it doesn't even know that there's something in there like we're
just in Windows fans haven't spun cards
yeah I think we're going to just call this one a loss for now I'll come back
to it later and maybe have another look but this one's bad vibes 1080 TI 980 TI
980 was afraid of that there's nothing obviously wrong besides that it's
clearly been stripped and presumably is
dead one of the many unfortunate things about this card is that it came with a
PCIe power pin that just fell off in shipping we need to reattach that before
we can try and power it on given the burn marks on this I don't think it's
the first time it fell off pins back on now we just have to
figure out which way these connectors are on cuz if we put our power supply
cables on the wrong way the card explodes or our power supply shuts down
either way don't want to do that that's ground yay so the end of this that has a
little clip is a side that has ground we just need to make sure that goes on the
right way oh God this is really
sketchy do not do this ever any of
it we did it how confident are you that this one will turn on I feel like this
one's hovering just above zero picked up the thermal camera the reason
that I want this is just to try and see if there's a short anywhere it should
just be hotter than everything else and then hopefully we can go from there oh
wow look at this though it has all of the covers for the display outs that's
uh impressive wait what no what the No
No Way what how would this turn oh my
God gForce gtx980 T what why is this
on I'm flabbergasted you should go buy a
lot of T yeah holy I just applied thermal paste I can't believe this is
just working this is crazy this is actually crazy that 980 TI we got for
$103 it ran score is a little bit low like it's 1,700 points under the average
but there wasn't a cooler on it so like pretty good yeah let's see if HDMI just
doesn't work is it working oh it is this
card just works wow yeah this card going for like 350 400 bucks we got it for 103
hell yeah call that one a big win I don't want to take these connectors off
I'm going to break the pin probably just going to use a little bit of thermal
adhesive and stick some mini heat sinks onto the memory chips that aren't going
to be getting direct contact to the heat sink the rest I think is going to be
totally fine with just airflow directly hitting them here I hope it still
works for cool I'm going to zip tie this fan to the card hell yeah yeah now we
just have to plug it in without breaking the pin off again this pin is falling
off so I'm going to just use our PCI to hold it in place can't believe this card
is working the only thing I can think of with this card is that it had the stock
thermal compound on the GPU die and it was just completely dried out so maybe
it was just booting up almost immediately overheating and they were
just like ah it's dead well the score did increase a fair bit by turning the
fan up now it isn't quite as fast as I want it is getting up to about 83° and
we're probably losing clocks because of that although like look at this thing
it's working I can't believe it this thing's sick Big W here's our final card
and it's another one that literally had work done on it we have parts of it
right here like look even just on the PCIe all scratched up we're going to see
what we can do though let's take it apart and we might have another water
damage card these thermal pads seem a little bit wet it's not looking good
David what's on the go here oh this is
bad this is really bad just look at the corrosion on this card right around
here I feel like this card one of two
things is going to happen either we clean it up and whatever is shorted by
Shmo up in here just kind of solves itself or it's completely dead it's
probably completely dead oh this is terrible this thing's not surviving this
David so oh where do we even start with
this it's completely black and there's just I don't even know what's all over
it like it looks like the PCB here yeah
is just completely lifted up there's a pad here that's no longer really
attached yeah the pcps kind of exploded
all through here some of it just came off as I touched it that's a good sign
it's also really hairy I'm not a huge fan of that uh let's see what else we
can find on here yeah so so this resistor is just crumbling I don't know
what to say other than I don't know enough about Electronics to really
comment on this besides just complete destruction of everything that's kind of
around this area we'll give it a clean at least see what it
exposes this poor
card what I find really interesting about this card is that it's water
cooled and it appears to have water damage but I don't think that the water
damage is related in any way to the water cool
everything around the Dy and around this all looks fine it just kind of seems
like someone spilled their drink on this corner it's kind of hard to see through
this camera here but uh if I look in
this there's a literal hole in this PCB and I don't think it's a via or it might
have been at one point but uh it's much more than a via at this point it's a
almost resistor sized hole that just kind of goes through a couple layers
like it looks like a cap exploded and corroded everything but like there's no
caps around here that exploded it's just something very bad got on this stayed on
it for quite a while oh yeah that just came right off I think we just Chuck
this in the PC see if it does anything there's no coming back from this I don't
think the only way to save this card that I can think of it's just full
zombie it like just pretty much everything from here never use it again
get like an external 12vt power supply for this and hook it up like right to
the vrms or something we might as well try the card but this thing so mangled I
don't even think it's worth the time to put that cooler back on I'm just going
to hold this Intel stock heat sink up to the die I have been wrong before but
nothing yeah I don't think it's worth looking more into this card it's mangled
this one's an L we paid $400 for this
David by a steam deck though yeah that's bad aside from what we just tried with
these gpus there are a couple more methods to try and bring them back from the dead like for instance our rx580
here you're able to rescue from a bad BIOS by just getting lucky and there
being a switch but on most cards you don't have dual BIOS to try and fix
those you can use one of these guys right here a BIOS flasher and you can
pick these up on AliExpress for under $5
with this you can Flash the BIOS on your card without even needing to power the
GPU on the best resource I found for this is a video from De dog that goes
over the operation in excruciating detail if all else fails there's also
the good old oven trick lonus did make a video on this a couple years ago but
maybe don't watch that like half the video is him just cleaning a toaster
maybe just read this article by I fix it basically by heating your GPU to around
200° C if a solder joint is cracked it
might expand just enough that the connection gets well connected again I
have heard people describe this as reflowing the solder but realistically
the ovens are not getting hot enough and if they did it'll be a really bad time
because all the flux is gone this is pretty much just a Hail Mary though and
even if it does fix your GPU it's probably going to last a month or two so
should you buy a for parts GPU from eBay and try and fix it no I I think you
agree David absolutely not this was fun
like I enjoyed looking at how just mangled this card is that I paid $400
for I wouldn't recommended sure you
still can get lucky like with our 580 or 980 TI but multiple of these already had
serious attempts at repair done to them if you're looking at less powerful cards
than maybe you can find one and it can be fun it's not too expensive but given
the current price of gpus there's a lot of incentive for repair shops to try and
fix these and sell them as working cards on top of that even if you have a
fullblown board repair level shop like
you might just not be able to get some of the stuff if something breaks like a mosfet you can get it from Digi key and
replace it but memory or die and a lot
of other special components you just can't buy them and it's sucks if someone
out there knows how to get gddr6 let me know so huge thanks to origin PC for
sponsoring this video their Millennium 5000t worked awesome as our test bench
and it was really nice knowing that performance and thermals are not going
to be a bottleneck in our testing the fact you can swap a components without
avoiding the warranty is straight up awesome and also like just look at it so
much RGB it looks cool so thanks for watching this video hit like get
subscribed and if you want to watch something else maybe watch your crazy
trying Tik Tok Tech hacks that they were bad
