This is our Failure Analysis report of the AMD Ryzen 7800X3D CPUs that exploded on our test benches -- some as a result of over-current, some as a result of degradation leading to failure. We worked with an external Failure Analysis Lab to evaluate the result of AMD 7800X3D CPUs getting too much voltage (VSOC especially) and likely too much current, especially in scenarios where ASUS OCP fails to do anything useful. This complements our prior Root Cause Analysis we performed in part 1, linked below, and uses a scanning electron microscope, C-mode scanning acoustic microscopy, and more to investigate a burned CPU that came out of an ASUS board.

Explain it to me like im congress
Seems correct since you're talking about ultrasonic frequencies.
Lab was in Japan, wasn't it?
Edit: Or you used footage from one to provide an example of the machines in use.
What's there to test for? The problem is that the BIOS is allowing the motherboard to supply excessive voltage to the CPU. Which electrical product in this world can withstand a voltage higher than its design including OCP?
Even though Gamers Nexus do not ever produce paid content or "sponsored content", that doesn't mean Gamers Nexus won't make misleading reviews. This so-called problem is very simply that the BIOS is allowing the motherboard to supply excessive voltage to the CPU, so it is very simple to fix this problem, that is, it is forbidden for users to increase the voltage at will. This incident is simply that the user abused the high degree of freedom of the BIOS to set the voltage. Now motherboard manufacturers have greatly restricted the freedom of voltage setting, and similar incidents will not happen again in the future.
I'm telling you right now: this series of videos has permanently raised the bar for what will be expected from channels doing hardware reviews and investigations. This is next level.
truly.
Seriously, this was the real deal.
Well, YES, some have put themselves forward, some have retreated, some have targetted science over CASH...
It took 15 years for GN to finally have content that isn't just complaining to keep their meme status :)
first time here I take it? I mean.... not a first for GN, so de-flowering verbage is yours to own atm LOL
This is fantastic! I'm a senior nondestructive evaluation engineer and use the analytical tools you've showcased on a daily basis. The scale and quality of your presentation is something that just... Doesn't exist in the public domain, and I'm thrilled to see this kind of work; you've certainly done the topic and field justice.
Are you also work in place you couldn't tell us about for reasons you can't tell us?
@@maxdefire what reason would this person have to lie? Clout in this one comment thread? Come on.
@@maxdefire Go back to truth social with your anti-science. It is not hard to admit that the lab GN used likely works with hardware manufacturers and that disclosing their name would lose them business. The best part of science is that the measurements and evidence stand on their own, the lab company name does not matter. You are free to buy a chip and pay your own lab to corroborate the findings if you are unable to recognize facts on your own. It is absurd to suggest GN is faking data which would get them sued.
@@TAP7a 4:03 maxdefire was making a reference to the video.
That's so awesome! And thanks for saying that. We're fascinated by this kind of work and have huge respect for it.
As a professional with a background in RCA and FA, I've never seen it presented in a public forum quite so accessibly. This has definitely set a new benchmark for TH-cam based public forum discussion!
What is RCA?
@@Melanie16040 root cause analysis
@@Melanie16040 FA is flight attendant.
Very interesting combination of professions 😂
@@Melanie16040 root cause analysis and failure analysis. Basically why did it fail and how did it fail.
Not only are you guys developing your own expertise and equipment for hardware analysis, you are gathering a group of experts outside your immediate company. The world needs more of this.
For those interested in cars, the car review equivalent to this channel would be savagegeese. A guy who started the business because he was fed up with untrustworthy industry shilling, and he doesn't play a clown act for lowest mass appeal and doesn't move from Idaho to L.A. just because everybody says you gotta go there for car review industry success. He talks personally and advocates for passion about what matters, the core substance. I.e. his focus is on journalism over entertainment. Like the antithesis to Top Gear.
Even when he feels the pressures of his chosen extra-hard path and has to make some business compromises, he tells you about it in depth and sincerity.
Born too late to explore the frontiers. Born too early to explore the galaxy. Born at just the right time to enjoy Gamers Nexus thoroughly breaking down manufacturing, faults, failures, mishaps and responses. Love it.
@@aaronmoore3050 You can
I'd say this is a good enough compromise... though tbh I would not want to be on the frontier. That stuff just seems like it was a whole wagon load of suck
The adventure of starvation/ dysentery vs the adventure of freezing / imploding
Also born at the right time to explore infinite worlds created by AI. Just don't die in the next 5 years or you're going to miss out on so much.
The only thing I really enjoy about this body is the computers and stuff on the computers, sadly the quality of people is often the quality of a GIgabyte power supply connected to an ASUS board with the soul of an 11th gen processor.
I really like how GN is able to take a current issue and talk about it in a way that they're able to provide an interesting response on so many different fronts
Thank you! We'll keep doing this!
@@GamersNexus a current issue, and a voltage one too!!
@@GamersNexus Thanks GN… as an update since I rebuilt my 7950x3D/MSI Mag x670e Tomahawk system on 4/23 and updated to new BIOS on 4/28 I have ran with EXPO on and no issue… SOC voltage has been locked at 1.3v. Any further part failure issues I will contact you!
@@iamastrangeloop96 hehe good one
@@manitoba-op4jx yeah I'll tell you watt, was pretty Amped to make that joke
As a doctor that utilizes all these imaging modalities in the medical field, it is absolutely stunning to see them applied in this way. I mean, the epoxy/cross section technique is literally how we do histopathology with tissue samples. It is obvious what an incredible effort the team has put into this investigation and it is presented in such a thorough and accessible manner. You are doing huge things for the community 👏 and we appreciate you all so much!
This is super well done, GN. Might I recommend more of those "bearings shots" like at 14:55 in the future? Or a 3D model of a deconstructed CPU in the corner to clarify where you're looking at each stage of the analysis?
Definitely can do!
@@GamersNexus TH-cam recommended this 4 days late… but yeah totally agree these images were super helpful and quite frankly cool to see in general
I find the amd copyright mark fascinating because it's dated before the CPU was actually released. Just shows how long it was actually in development.
Definitely a great point on that!
I thought the same thing. 2021, release 2 years later.
The development cycles on cpus/gpus are measured in years and have been for at least a decade!
Yeah, and you can bet they were working on it for a couple years before that mark was made too, so they are always thinking about 5 years into the future, teaching sand to think takes a long time and so much work, it really is amazing.
@@Dan-Simms if you ever felt the need to travel to the future this thing looks like a good start xD
I did some IT work years ago and once a coworker was sick and I went to their client, a small failure analysis lab. The place was tiny, but filled with equipment everywhere. This was decades ago, but it was a ton of fun to see all the equipment and the photos they had all over, and on their monitors.
As an NDT inspector to see our industry methods of inspection applied like this is so cool. Thank you for doing this inspection.
stop lying about your occupation.
@@Warhorse469 lol
@@K4nj That guy uteopia uhg... He has made similar childish snotty yammerings to several commenters.
I think his mom needs to take his pixie stix away and get him to take a nap.
@@phlogistanjones2722 I'll still take the kid trolls over the giveaway spam any day.
@@Warhorse469 understandable you wouldn't believe him considering the large amount of people that just happen to stumble upon a video of an incident that they just happened to be involved with somehow. in this case though they're really an NDT inspector, not like it's that rare of a job they're all over the world and more then likely would be the type to watch tech videos to begin with.
Ohhhh my god. I cannot stress enough how awesome these images are! As a material scientist myself, I have worked with all these techniques myself in the past years, but this has been done on an extremely impressive level of detail and technical skill! Hats off to that FA lab, they really know their stuff!
Why can't they talk about it? Is the nature of the work highly secretive? I guess I'm wondering if it's industry standard, or something different, because I'm interested in this stuff.
@@warhokn4178 With this amount of tools and knowledge, they likely work with big chip manufacturers directly (maybe not AMD/Intel, they probably have their own, but maybe Qualcomm etc.). Don't want to break any bridges by allowing the public eye to see stuff that usually is reserved for internal use only.
Me too! Love these SEM images. "Maybe better magnification than you can get with a normal microscope" is a big understatement though lol
@@vocassen Not to mention, there is probably some expansive and gnarly NDAs in play here.
@@vocassen That makes sense to me.
That is an impressive amount of test. I can't believe you went through all of this to find a specific issue.
Remember the hands-on we did was mostly Root Cause Analysis -- our Failure Lab contact externally did the stuff you're seeing today! It's an awesome amount of stuff all combined!
@@GamersNexusI think maybe he meant at least coughing up the amount of money for this testing. This could not have been cheap getting all of this done.
This was fascinating! I feel I learned some things.
@@GamersNexus Guys this was amazing!
Thank you for this Steve, we definitely would never have gotten to see anything like this if AMD had gotten their hands on it instead, and they no doubt still got enough data from other boards to fix it themselves.
THANKS STEVE
AMD got their hands on a whole bunch of RMA'ed dead CPUs by now, and they're not making a peep, hahaha.
If I was them I would say thanks we will pay great attention to this. Bummer that this was a 3D chip. I upgraded my 3000 series processor to the 5800X3D and it was an excellent upgrade.
@@haldorasgirson9463 This failure has been reported for non-X3D chips as well. This seems completely specific to AM5, and from Buildzoid's analysis this is purely a voltage regulation issue that is entirely preventable with firmware.
@@arkain1 Well, it is possible they are seeing the failures themselves and are working on a solution for both hardware and firmware. I mean, let's be completely fair here, as this issue mainly affects ASUS boards, so maybe AMD didn't know about this issue right off. I'm sure they will correct the issue in the interest of public relations.
This just reiterated to me how amazing it is that they manufacture these products in such vast quantities. It really is hard to believe how small all of the connections are and that it works at all.
It's mad isn't it? Especially when we get down to that scale and you can't even see a hint of a transistor.
@@memitim171 Its instane tbh how a light beam can make transistors and do this on such a scale seems almost impossible that some metals can make something like a cpu.
@@synapse5791 Yes it is amazing! To be accurate transistors aren't made from metals they are made from different metal doped semiconductor material which is usually Silicon.
@@linmal2242 Yeah Its still kinda amazing how they work. Like how do you tell a bunch of materials to do something in a linear way which you can easily control? Its really
yep we can´t even inagine there is a big AMD logo in there lool
Thanks for the insane effort, Gamers Nexus team! That must have been expensive as hell.
Here's the video we've all been waiting for! Great work as always GN - your contribution to this industry cannot be understated
Very kind of you to say! I don't know that we've changed a ton yet, but we're doing our best to influence companies in a positive way!
@@GamersNexus The power supplies no longer blowing up, AIOs being avoided etc say different. Seriously its not just the changes from manufacturers but also awareness for consumers. You've changed so much and the fact that you're still here and have somehow managed to keep that integrity is awesome.
@@GamersNexus You've really made an impact. GN has been able to put pressure on manufacturers in a way no one else has - Nvidia with the 12 pin issue, Gigabyte with their PSU issue, Nzxt with their riser cable - the list goes on. The combination of your thoroughness and experience and your journalistic integrity and independence makes GN a force to be reckoned with, and manufacturers know that now
@@GamersNexus OH you HAVE. Personal example: The Fractal Torrent Case. They ***CAME TO YOU*** and told you about an issue AFTER you gave it a glowing review. They pulled the product. FIXED the issue. I bought one for EXACTLY that reason.
So yes, you DID make a difference.
Thanks for a great video, normally I don't donate but this time is different. A lot of effort put into it, and absolutely your vid raises the bar. Congrats for the entire team. I only wish you included more behind the scenes from the scans and the analysis, but totally get it why you couldn't. Cheers.
Thank you so much for the support! Yeah, would love to show more of the lab itself, but sadly they have too many confidential projects in the background so they can't be shown. Still thrilled with what we got!
@@GamersNexus Understandable, especially in this age of aggresive privacy invasions, data & information theft. Keep it to yourselves, isolate those from the internet, even avoid speaking about them around your phones. You probably know better than us how much our electronics that can connect to the internet are compromised.
This is really incredible reporting. I used to work in a clean room and had to do SEM and similar type measurements on our wafers. This is truly Ph.D. and academic level analysis. This is like what many researchers would be publishing in academia. What's more is you did it all in just a couple weeks. Very well done. I joined your channel over this. You guys deserve it. Great reporting! Nothing like this on any other channel I know of.
I have seen PhD students who aren't half as thorough or scientific during their thesis defense. You really set the bar high. Heartfelt thanks to Steve, Patrick, Mike & Vitalii and the rest of the team.
Feeling good about the mats I ordered last week. Happy to support this content, thank you for your work on this.
Thank you so much for doing that!
Thanks for investigating so deeply GN team it's wonderful to know there's a TH-cam channel out there to inform the consumer. Hope you guys continue to grow and have fun can't wait to see the next big project.
I feel like I absorbed 100% of this video's information despite how technical it all gets. Your presentation and breakdown is amazing. This hits that perfect spot in being "edu-tainment".
You guys are amazing! The work you do is incredible. I'm so glad that someone is letting the public in on this instead of any analysis results disappearing deep in a drawer at the manufacturer. Big thanks also to your partner who is setting new standards with their methods and tools.
This was absolutely fascinating. But honestly, the more I learn about the structure of CPUs, how they are made, and how they work, the more I am convinced that they really are magic. The fact that you can zoom in so far, with all sorts of advanced equipment, and yet still not be able to resolve the transistors, is absoutely wild. It's one thing to hear "20 nanometers, 11nm, 7nm" etc but another entirely to understand just how infinitesimally small that really is.
Yeah, when people say that we will eventually won't be able to shrink the transistors more because on the quantum scale physics goes out of whack it sounds like Sci-Fi, but we are almost there already.
@@AlleonoriCat we are almost there already. The different layers are barely more than one atom thick and because it's so thin they're limited at how much more they can shrink while still keeping electric flow under control - the risk of cross-talk and shorts becomes greater every time they shave a nanometer off
@@thesteelrodent1796 The transistors are small, but once you get to the vias and interconnect layers, they become huge in comparison, thousands, tens of thousands of angstroms ;)
But on the silicon it's damn small.
Imagine the machines (ASML) that make these chips ;)
They should be able to resolve the transistors if they zoomed in and took the time to adjust the astigmatism and focus with the SEM
Love the content, very thankful that the tech community has a group like Gamers Nexus that loves both tech, the community, and troubleshooting to this extent. Thanks Steve and Crew for all the reviews and content you provide. Also, thanks to the fantastic work at the failure analysis lab.
Thank you so much! And we've let the lab know the community appreciates the work!
As a retired EE this BLOWED me AWAY ! I wasn't expecting this level of Science displayed in such a PROFESSIONAL Manner & DEPTH, "BRAVO" !! 🎓 I think you have out-done yourself this round. LINUS would be PROUD of YOU ! 😎
You deserve a "bonus donation" from AMD you did their job for them. AS a Technician myself this is an awesome video. Thank you
In all honesty, while it is clearly a problem that this has happened, I can't help but be truly impressed at the astonishing scale engineering and knowledge that has to go into the design and manufacture of chips. And stellar content like this allows me a brief but incredibly meaningful glimpse into that world. Thanks Steve and team. You guys are slaying!
Even more mindblowing is how fast this technology progressed.
chips are basically magic labirynths for electrons made from sand
Yeah it's pretty mind blowing that these things work at all, considering the absurd number of microscopic parts.
@@TheSaival yeah the "graving runes into rocks" thing from stories
amd made a mistake and put a bit too much lightning and it created fire
It bothers me that there are so few companys in the world even legally allowed to know how this tech works.
Government protected trade secrets make me wonder why we tolerate the existence of patents in the first place.
The decision of separating this situation into 2 video definitely paid off, well done!
Incredible analysis and detail! Thanks for taking us along!
This video is incredible Sam, even including video of the equipment used in the diagnostics with great explanations. Thank you!
Btw that Fractal North in the background looks like a proper decoration.
Thanks again for the video GN! It’s always interesting to see the insides of these CPUs.
Super educational to see all this!
You expect us to believe some "lab" has all of this high tech testing equipment and just happen to test CPU's for you? Sure Steve, the gig is up. Show the secret testing facility you have out back!
hahahaha
He did say "testing we *currently* can't do" Give them time... the fan tester is just the beginning it looks!
It's a DOD lab, Steve has clearly become a DIA asset in the past couple years. Probably the only one there who speaks Chinese.
Why do you think they released a 15 year anniversary shirt? Gotta find some way to pay off all that hardware!
Area 51 ☠️
those microscope shots are incredibly cool. the scale at which these devices are manufactured is fascinating and frankly unbelievable
Unless someone somewhere someday is finally going Planck-scale and even further/deeper, nah, this is still considered "too large" and "nothing out of ordinary" by laser-etching automated industry's (DUV, EUV, etc) "standards". There's still a helluva lot of "spare room" for "improvement" and "downsizing".
This is true forensic reporting that stands completely unmatched in the industry. I have run SEMs ( a phenom xl similar to the model used) and this testing is many thousands of dollars, not to mention time consuming. The depth, detail, and technical competence of this report is outstanding. You really should write a white paper about this and submit it to a journal. You did all the work why not get some extra credit and show the industry that we are paying attention.
Despite not being an engineer with a perfect understanding of everything you described, this content is still amazing to see. Highly looking forward to part 3 of this series!
26:02 is basically a list of metal band names. Incorrect Doping. Stress Induced Void. Mechanical Overstress. Excessive Pressure. Hot Carriers, Oxide Defects...
Stress Induced Void sounds more like doomer's band, than metal. Maybe punk rock?
Respekt. Tolle Aufarbeitung auf besonders hohem Niveau!
I'm so happy to see you all doing this level of in depth. We have been needing something like this in the industry for years. Keeps the companies honest and teaches at a level most have never seen. I really love the work and detail you have put in to this.
That this level of independent testing is being done is absolutely incredible.
I assure you, the cost for this amount and type of FA is not trivial.
I just wonder why that FA lab prefers to stay anonymous. do they want individuals to stay away from them that much?
GN really is a champion for the consumer. Like we'd never, ever get full disclosure or anything like it if it wasn't for GN, it's contacts and the community support enabling in-depth analysis like this.
Absolutely brilliant work, Steve & co. Nobody else produces content this detailed, not even on TV.
THe work you guys do, is awesome, i find that there are very few youtubers, willing to go the lengths needed to truly inform the public of the problems out there and even fewer willing to spend cash to acquire failed hardware to test, at their own cost. thank you guys!!!
This was really cool to see! I can't believe it got hot enough to melt copper. Crazy.
I already bought a shirt when part one launched, so I guess I'll try this thanks button.
Anyway I'm off to look for that GN sandwich shop.
I do really want a substrate sandwich shop now...
Thanks so much for the additional contribution and the shirt purchase! That's all very kind and we're humbled to receive the community support and appreciative.
@@GamersNexus Dude, you guys don't even have a fully functional kitchen in the break room! I spent four (?) years being low-grade annoyed that nobody could even make a grilled cheese and tater tots at old office. Feed GN!
Great content, as always!
@@GamersNexus Would love some melted copper on that sandwich 🤣❤️
The imagery and explanations are awesome beyond belief. Happy to be a GN Patreon and play a part, no matter how minuscule, in getting this sort of data available to a bigger audience.
Thanks! Appreciate the effort put into this investigation.
This is unbelievably fascinating, and to think we'd never know about any of this if the issues were left to the manufacturers to remedy. If anything, they should be thanking you guys. You probably saved them a ton more RMAs.
Many thanks to you and the team for all you do.
As an electronics engineer - that was fascinating to watch, some amazing content there. Great job to everyone.
Man... it's gotta be hard for PC hardware manufacturers to pull the wool over the eyes of the consumer base, when you have objective engineer-grade examination & testing coming from one of the most reputable critics in the scene.
Unironically... thanks, Steve. Keep being a thorn in the side of PC hardware companies.
I love videos like this! It helps to explain the reason why something failed, instead of saying "It failed" and that's it, you go in depth into finding the reason. Thanks for sharing.
materials science grad student here - always love it when y'all get to do failure analysis videos and get all this neat microscopy and XPS data. you present it in an extremely accessible way and i love seeing materials science analysis techniques being put front and center. wonderful journalism as always, keep up the good work
BS in MSE, class of 1999 here - this brought back some memories and showed off some new techniques / equipment. GN never fails to deliver!
Finished my MatSci PhD last year, working in the industry now and yeah I'm always tickled when I see youtubers sharing this sort of stuff
Your work is unrivaled. Thank you so much for your hard work and dedication.
Thank you so much for the support!
I am thoroughly impressed with all of your diagnostic capabilities. This is really well done and what separates your channel from the others. Nice work.
I haven’t been keeping up with the channel that closely in the last few years (busy in college). Even so, I couldn’t miss this! This is some of the coolest, most well produced content I’ve seen in a long time.
Wow this is so damn cool to see! I'd love to see what the day-to-day is like in that lab! Thanks to everyone involved to bring us this video!
I work in a FA Lab, its quite fun to see different things every day. The FA lab that GN sent the sample to did a pretty good job.
I worked in one for a while (and still regularly use similar lab services, and have a cross sectioning lab setup minus a SEM ) once you are over the shock and awe of the capabilities ... its about as exciting as a dentist office, but since its full of nerds there's a lot more pranks
Ironic considering that these failures are coming from a lack of cooling.
I'm not home and decided to watch this while out and I just HAD to log in to show my appreciation for this video. This was one of the coolest videos I've ever seen on this entire platform and you all outdid yourselves on this one. I already was gushing over that 3dfx recreation video you guys did and if this is the kind of quality you guys are doing for your "specials" from here on out then y'all have clearly evolved into something far more than just the regular tech journalism we've seen in the space for years. Fantastic job by the team, fantastic job by the FA lab, and we should all consider ourselves lucky that you even exist in this space where this would have likely just been blown over as a few unlucky people with blown cpus rather than the educational masterpiece this has become. Awesome work.
-Also hey, when are we getting a GN Burger Substrate Sandwich shirt?-
One of the coolest tech videos I have seen in ages! Love all the effort that went into this and the detailed scans. Never seen content like this before, bravo to the entire team and everyone that worked on this!
Oh man, i can't imagine how much effert it took to figure everything out. To channel stuff and everyone who participated in this investigation: thank you! You guys rock!
This is absolutely world class work. Amazing effort, as usual. Thank you to the unnamed lab, and engineer.
uNvidianamed failure lab that knows semiconductors and is setup for them lol just guessing, but ittd make sense why this would cause the engineer to be terminated if anyone found out...
This analysis is unbelievably cool! It's so rare to see these chips in such detail and magnification.
Massive props to both GN and the failure analysis lab for their brilliant work.
I've got to hand it to you, this analysis is next level. You've really gone above and beyond. This is why - even though I'm not really a gamer - I find myself gravitating back to this channel. It wouldn't surprise me if AMD themselves are watching this to try to understand the issue better.
Pretty sure they know everything about it by now. Or should. It would be a huge error not to, as you cannot fix the errors you don't know. Anyways, it should not have happened in 2023, they had problems with (lack of) CPU sensors in 2003ish.
AMD probably does watch this, as well as doing their own lab assisted analysis.
They will learn from this and shape up for a while after.
If Asus stops blowing up CPUs with faulty parts on their motherboards.
Omg this video was awesome!!! Having them breakdown the investigation as they ruled out possible causes. Amazing
Awesome work and really appreciative of this kind of investigation and analysis. Can't wait for the next video.
I work on semiconductor devices and have ordered many of these techniques for FA before. Being able to see a full FA analysis (very well explained btw) for the CPU I just bought is simply a treat I never thought I'd get. You guys did a great job explanaining the techniques, and it was so cool to see cross sections! The materials science / characterization nerd in me was thrilled to watch this and is also quite proud of you guys. Excellent video.
This is my favorite video from this channel. Great job explaining what is happing. Thank you.
Fantastic analysis of the issue. Keep up the amazing work !!!
THIS IS AMAZING! The amount of detail you can get out of SEM, just, blew me away. Also the fact that we can make things this small and reliably is just insane, and it's even things we take for granted now in days. We just expect CPUs to just work at such a small scale.
"Also the fact that we can make things this small and reliably is just insane." Ironic comment, considering. You win today's Internetz! 🤣🤣🤣👍👍👍
ABSOLUTELY NEXT LEVEL! The fact that y'all, as an independent group, invest so much time and money investigating these types of situations, AND that y'all disclose everything that's legally possible to disclose is incredible! Obviously there are limits, and y'all can't violate NDAs or expose sensitive IP, but y'all do walk right up to that line, so thank you!
Putting this whole thing together, and educating the public on the possible failure paths is something y'all should be extremely proud of, because as far as I know, nobody else is doing this kind of work, with this much detail, with this much transparency!
I cannot express how grateful I am for this channel and the entire GN team, and I'm damn sure that I'm not alone in that!
Thank you again to everyone involved, and even though you had to keep the failure analysis lab and the FA tech's name confidential, please pass along a massive thanks to said FA tech & lab.
Awesome, just awesome.😀👍🐧🐧
That was a lot of science. You've really pulled out all the stops for this one. Great work! Fascinating stuff!
Thanks for your hard work from an EE student who loves the truth and not the marketing lies.
I work in the semiconductor sector in Metrology. So seeing this in-depth analysis is awesome and concerning at the same time. Thanks guys for the education, long hours, money spent investigating!
know you don't.

Absolutely incredible. Peering into the heart of a cutting edge process, and the damage that can be caused by gross negligence. I'm astounded that such temperatures can be reached when things do fail. I'm blown away by the effort and the content. Thank you for all you do, GN. ❤
absolutely amazing video series. thank you for diving so deep into these issues!
The level of detail here is crazy! Amazing work!
12:10 I swear to the Simulation Gods that computers are just simply magic. This microsopy puts into perspective how far modern technology is, not only seeing that tiny, but creating something even smaller and giving it a freaking function. What the hell man
honestly the amount of depth you go into is literally insane but if companies know there is a group of people who can do digging like this they will probably react better(one would hope). You and your group really do this community a service and I appricate it a lot.
Yep, Gamer's Nexus is to hardware what Digital Foundry is to software.
Keep up the fight for the consumer, we genuinely appreciate it.
CPU CSI in action! This is probably the most detailed investigation of any CPU failure ever. Good job!
Outstanding investigative journalism, fellas! The amount of data presented here was so cool, and amazing!
Thank you for this awesome, ridiculously detailed look into this!
Thank you so much!
I used to work at a microelectronics plant in the 90s. The designers were always putting logos and letters at the micron level, partially because they could... but also because corporate espionage is a thing. If some company copied a chip (easier to do back then, as chips were not as complicated), they would often copy those logos as well.
The right level of educational, investigative and nerdy content, boiled down to one video. Thanks for all the hard work GN!
This kind of high level reporting with incredibly expensive imaging is so impressive to see and I cannot praise GN and their contacts enough for bringing this kind of data (and going to the effort of explaining it!) to the public. Keep up this kind of reporting boys, you are doing the work we need and want!
Imagine just how quickly and quietly ASUS and/or AMD would try to sweep this under the rug with a superfical and shallow statement if GN wasn't around
leave Britney alone, AMD are flawlesssss!!!!
AMD set limits Asus did not follow . If you over clock by default it is not AMD at fault
100%
In the previous video GN quoted their source from AMD. So they already figured out the problem at the time. ¯\_(ツ)_/¯
asus saying nothing basicly gaslighted everyone to think its amd
I never expected to see highly-reputable science publication-grade images on GN and yet here we are.
Calling the work done here "outstanding" wouldn't even scratch the surface of it all.
Thank you for all you do for consumers ! :D
I am glad your having fun doing this. Im worried as this new build cost me a lot a loan over 12 months and now I dont know if my pc is going to go bang or not
This was an awesome video! Nice work Steve to you and your team.
Great job as usual and gives a once in a lifetime insight on how these types of tests work and what they reveal. Can't wait for the third and final video in this trilogy saga. Just befuddled on this whole dilemma and hopefully my setup doesn't go caput as well.
This is the stuff that the manufacturer doesn’t want us consumers to see or… the stuff we really want/need to see. Thank you for always pushing the bar GN.
...what a dumb comment
Impressive initiative and analysis. Good video. Thank you!
You guys ROCK! Thanks so much for looking out for Consumers like you do!
Beyond excellent. Beyond top tier. IMHO the most excellent, informative and useful YT channel I’ve ever seen. Just wow!
Great, informative piece! Amazing detail. Love the humor!
This was SO interesting!
I always wondered what they really looked like underneath that die, but I had no idea of the level of complexity! this is SO COOL!
Wow amazing work GN.
It was a blast watching this analisys.
Thank you all for putting in the effort and making the video and the Lab for making it possible. This is pretty much a first in the YT tech channels.
It's great to see someone provide this level of detail and professionalism when it comes industry problems. Providing digestible information to not only inform the users but manufactuers as well and hold them accountable for their actions. These in depth analysis videos are great, keep it up! 👍
Wow, the quality and love behind this video is amazing.
Outstanding! Wicked cool work you guys are doing, never stop!
Man, it is fascinating to find this whole world of insight and learning you never knew existed. Kudos to the FA lab, hope we keep seeing their work.
