what happens if you buy a brand new computer or you build a new one yourself
and you get a faulty ryzen cpu well in today's video i'm going to go
through this ryzen 3 3100 right here and we're going to look
at how it actually is faulty compared to a
normal ryzen cpu and this was the weirdest thing because
i went to boot this thing up again after i did the review
and it still runs the cinebench scores and it still does the cpu side of things
absolutely fine but there's one big problem it has
where it can't communicate with the graphics card properly and actually the
behavior differs from an nvidia card to an amd
card now in the past i've only had actually one
faulty cpu that still managed to do a little bit of
work here and there and that was an intel cpu i'll put the link to that
video up here but what happens if you get a faulty
ryzen cpu well in today's video i'll explain the
best i can about what the symptoms are of this cpu
and what are some of the things that you can do
if you come in to this very and i'm going to say this extremely
rare situation and before we go on i will say yes i've tried everything
different motherboard different power supply different memory
and different graphics cards of course different ssd and
it is definitely the cpu and i know there's going to be one guy in the
comments he's like dude have you even tried telling it not
to ride on the highway whilst listening to inxs
yes sir i have even tried that do you own
a smartphone in 2020 well i'm guessing most of you do and in that
case today's video sponsor philmore go has a very powerful free video editing
software and it's a very powerful tool where you can edit clips on your mobile
phone or even import clips from other camera sources and start
editing with even one hand it's got powerful transitions to choose
from and the best thing is it runs really smooth for a smartphone i
was actually blown away by how cool this application is so if
you want to download it or find out more information
about fillmore or go then i'll put some links in the description below for you
guys let's get back to the video so here we
are now in windows and what we can see now is
the display adapters here the 5600 xt
is showing an exclamation mark next to it
and so naturally one would think if they built their whole pc and they were
seeing this exclamation mark here they probably
think wow my my graphics card's faulty and this graphics card believe me it
works on every other system here in my studio so i know it's not the
gravis card and so that's when i started testing out everything else and i was
like wow this is the cpu that's faulty but
this is a bizarre thing it locks in the display resolution at the native 1080p
it's as if the graphics card drive is installed on the amd side of things but
it's not installed so if we even go to boot
up something simple like the unigine heaven benchmark which
we'll quickly do now it'll just crash out it won't do
anything so let's quickly do that so this is what happens when we boot up
unigene heaven it gives us this fatal error here and it spits out like
a mammoth list of errors so this is getting to be a little bit
interesting so what we're going to do now is jump into the bios
and just see what's going on but one thing i will say with this problem right
here is it's actually a little bit dangerous
because this is the one reason and this is how
i initially knew something was terribly wrong was i booted up my system and
usually when i boot up my test systems i've got
20 other things here to do in the studio and then this whole system just
shut off like i was like why did this shut off and then i felt the gpu
and it was burning hot so this gpu currently
basically the fans are not spinning and even in idle the gpu will still use up
some power so the problem is is that it's
just going to keep getting hotter and hotter and hotter
and then it will just switch off and thermal like thermal throttle and
thermal trip and so that's a dangerous thing because
this faulty cpu could cause the gravis card to become
faulty if it gets too hot i mean usually the safety measures are pretty good
but if you become unlucky in some scenario
it could make your gpu faulty so when we're looking in the bios here
nothing is out of the ordinary everything was on default values the
memory wasn't even overclocked either however what we're going to try to do
now is what i call a hail mary attempt and then we're just going to up the
voltages of literally everything and see if we can get
something different out of this cpu this is the final
attempt before we move on to the behaviors on say an rx 470
and also an nvidia graphics card um excuse me brian but have you tried
just simply turning it off and on again i've tried that i've tried reinstalling
the drivers on different ssds like 10 times
even with the hail mary voltage throw at this cpu right now
it's unfortunately still not working this
this is no chance for this but what i'll quickly show you is something really
cool and that is it still runs a cinebench r20
[Music]
[Music] so this graphics card right here i'm
glad i got this on camera because this one just went to
like a void where it made the whole screen
like sort of like a cream pixel color and now it's
actually restarting so you would think just like the 5600 xt that this
is a faulty gpu but we'll quickly try um the last thing we'll try is an nvidia
gpu one that i've actually never tried before let's go with a gtx
645 old school and so this thing actually boots up into
safe mode and within safe mode it's saying that the gpu the rx470
is being displayed properly but upon trying to boot up a benchmark again
unfortunately we are met with an abrupt end let's finally try that nvidia gpu
but it still says here as well like pci device so
i'm guessing the pcie controller is what's really
busted in this cpu
[Music] and then the cpu said to the gpu in a
bogan-like voice sorry can't help you mate so instead of
finishing this video off last night i decided to
do a bit of research and digging on google to see if anyone else has had
this particular problem and from what i could see is there was
only maybe one person who potentially had this problem
it's just they never really replied to the thread so you never knew but
the symptoms they were talking about were pretty much exactly the same as me
but the thread sort of put it down to the
power supply and motherboard and stuff like that
and here's the funny thing after thinking about it i was
i went back and there was one reply on the thread that said try all the
different pcie lanes i had tried only the top two pcie lanes
or the 16x slots on my motherboards now with a lot of am4
motherboards the bottom slot even though it's a 16x
slot is actually truly an x4 slot and it runs off the chipset rather than
going directly to the cpu so what i decided to do here was put it
on this real like at the bottom of the board where
it then blocked out the power button on my test bed and trust me it was kind of
awkward trying to turn the pc on you're like going
hey yeah trying to do a little like uh flick shots
in there to get your power button on but anyway we gotta boot it up
and the graphics card is now being recognized completely normal and it's
benchmarking absolutely fine so that was definite proof
that the cpu has buggy pcie lanes and so this right now is just an
extremely rare example of what can happen in the land of pc or it
can happen really in any new product with electronics on it you
can get a weird fault that makes it through
testing phases but then after a few weeks of using it
something just becomes faulty and really what we put it down to now is
what you can do if you come into a very rare scenario like this
and the news is kind of fortunate and unfortunate depending on which side of
the fence you're on i know a lot of you guys out there who
watch my channel you guys delve in a lot of different hardware especially used
stuff and the good thing about that is if
you've got spare motherboards and spare power supplies and
spare memory and stuff like that you can quickly diagnose
what the problem is in my case i changed the motherboard the gpu
and uh the ram and the power supply and straight away i was like okay it's
really just the cpu that's left to go and so it only took me a small amount of
time to figure out what was wrong but if you're in that side of the fence
where you've got the spare hardware or you've got a friend who has
a very similar setup and you can quickly diagnose via pretty much
trial and error what the problem is then you are on what i consider the fortunate
side of the fence but then we move on to the unfortunate
side of the equation and this would be someone who's built their first pc
and they don't have someone close by or they don't have any compatible
hardware to test out what could be potentially faulty
now in this case the worst case scenario would be
you've bought all your components from different hardware vendors
and you don't exactly know what the problem is because if you take a working
graphics card that maybe in this case appears faulty back to the hardware
vendor they're just going to get it and say hey
there's no problem with this graphics card send it straight back to you and
then you're going to be still scratching your head and then
you'll have to eventually be paying all these shipping costs and all this time
and money when it could have been something else that's faulty so
in this case i would say coming out of this video if you're building your first
pc and you're gonna be buying all the parts individually
i would try to buy them all from the same retailer because this when i built
my first pc there was a place um about 40 minute drive from where i
was and it was called game do computers and
i bought all my components from that same retailer now
i actually had a faulty stick of memory and so when i built the whole pc i'd
bought all the parts from them built the pc and i said to them when i took the pc
there i said guys i built this pc but i bought all the components here
and when i play brood war it's just randomly crashing out and they then took
the pc they said we'll take a look at it they called me
the next day and they said yep one of the sticks of memory was faulty
and so because i bought all my components from there they were happy to
take that whole pc that i built and run some diagnostics for me so i
guess that was one of the benefits of buying all the parts from the same
retailer but i guess of course if you go out and buy
from different retailers on sales you're going to get
a better price performance rig put together but if it's your first pc
and you don't have any friends that have similar hardware or you don't have any
spare hardware to test things out on i would recommend
just going from that one retailer just because of what you've seen in
today's video here so now back to the ryzen 3 3 100 and
if you're a consumer and you've bought a cpu and it's faulty you can get warranty
on that you've just got to return it to where
it came from and they'll replace it for you no problems
amd however they won't i think warranty bent pins so that's one thing do be
careful with your hardware and don't make sure it's not physically
damaged in any way shape or form but in terms of the cpu i've got here
it's going to be a very different story because
this is a review sample so i'm not sure how warranty works
with review samples the only faulty part that i've had that i've claimed on and i
have had a couple of like minor issues with
parts in the history of the channel but there's only
been one that's just been flat out bad and that was an rtx 2080 ti
from morris and they they took it back they sent us out a replacement
they really wanted to fix that for us and amd
i'm i've reached out to them they want to do the same thing
but i want to keep this cpu because it's so rare like i've never seen this
problem and even on the internet i can't find a proper thread
with this problem in it and so my thinking is is it's like
that uh if you guys i remember like when i was a kid i used to collect basketball
cards and there was a thing called misprints
and a misprint could be worth some some good money
as a collector so i kind of see this cpu as kind of like a misprint
where it was it just came out the factory and it still runs cinebench and
it still works when you use the chipset pcie lanes
so it's um just one of those rare things that i kind of want to collect
personally and uh yeah that i mean that might be a
weird outcome from this video but i guess weird host weird outcome
what did you guys expect anyway recapping today's video the most
important thing to come out of this is that
if you're building pcs you are going to sooner or later come into faulty
hardware and it's just one of those things that
happens and it's not the company's fault in this case it's certainly not amd's
fault they sent me out of cpu it was
absolutely fine and then it just something happened it went bad
and in the case of the rtx 2080 ti same with auris they
they it came out of the factory absolutely fine then something went bad
and so as i said before it usually goes bad very quickly
in the first couple of months if it's prone to failure and in this case that's
exactly what happened so if you come into this situation just
understand that there are steps to diagnose what is wrong
and the best way to do that and i mean seriously the best way to do it
is trial and error swapping out the parts
and you will find out what is faulty sooner or later
via that process and that's really the only way i do it here at the studio
it's the only really way i recommend doing it because that way you'll get
visual proof and you know exactly what the problem or faulty part is
and so once you find that faulty part make sure you go get it fixed
and the other thing is is don't run faulty hardware if you know something's
bad or it's not running right turn it off because you as we saw in
today's video earlier on the fans weren't spinning up on my gpu
that can cause failure on another component anyway
realizing life that can happen and i think eminem and
d12 they wrote a track back in the day about this exact thing so it happens
the way you deal with it is just take a step back be calm
look for any research that you can and of course trial and error is always
going to be your best friend in the case of diagnosing faulty pc
hardware and with that aside i hope you guys enjoyed this video if
you did then be sure to hit that like button for us also let us know in the
comment section below what kind of faulty hardware have you
come into in the past and what were the symptoms and how did
you go about fixing it love reading your thoughts and opinions
as always just like this question of the day here
and this comes from pidspuder place and they ask would the results be different
if you taped the mouse to an intel box or maybe a zen 2 cpu box
just asking for a friend and they're referring to the last video we did on
input latency with amd versus intel and i even threw in nvidia versus amd gpus
i'll put the link up here for that video it's definitely a cool watch if you're
into that sort of very like minute differences in hardware
and stuff like that um but spoiler alert it wasn't that
eventful like it's not you know you're not really gaining a
huge competitive advantage by going with one over the other
uh anyway to answer that question what have the results been
different on an amd cpu box with a zen 2 box or a
intel box and the intel box probably yes because a lot of those intel boxes are
skinny so the contraption might have fallen over
and it could have been damaged the zen 2 box no because i think the shape of the
actual box is pretty much the same in dimension so
the reason i picked that box was uh i was looking
this is how i do things around my studio i'm just like we're making this
contraption and i think i even made a whole video on
how i made this thing it took a long time
and we're just looking around and i've i i'm like okay i need something that's
this this tall it'll fit in the frame but it won't block the monitor out
and i it needs to be quite big because i need to put the mouse on top the light
on the side and we just there's an amd box staring
right at me i'm like perfect and i even use a i think it's
like a 3 900 x box under my monitor now with the tech
yes loving taped over it the logo and stuff like that so
amd boxes they're pretty handy for not just having
holding your cpu you can use them for other things around the house
i think someone's even used them for a tissue box and yeah i've gone on long
enough guys if you guys enjoyed this video and you've stayed this far
