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.

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?

@user-mm7ot5zq2c Год назад

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.

@jacksonsneed7689 Год назад

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.😀👍🐧🐧

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.

@herseem Год назад

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.

@FlorinArjocu Год назад

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.

@Arexodius Год назад

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.

I’m working in one CPU manufacturing site in the lithography department and to be honest I’m still learning and catching up on many terms and phrases you guys used in this series of videos but one thing is for sure, I’ve learned more from your videos then from one year of working with those products every week for 40 hours. 😃 And I’m not expert but I’m pretty sure that even nuclear catastrophe which happened in Chernobyl wasn’t investigated in such a precise manner with so much effort for all smallest details. Great job guys 💪it’s amazing to see so many new discoveries and to learn more about products which we all use every single day in our life and yet 99% of us have no clue what it really is or how it actually works. Can’t wait for the next episode ❤

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?-

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".

@DustinRodriguez1_0 Год назад

I got to tour a lab that does analysis like this (slight chance it might've been the actual one that was used I suppose) decades ago and it was cool as hell. I was in high school then and they showed off stress-testing equipment they used to test parts on the space shuttle, showed how they determined that replaced cables on a suspension bridge were failing sooner than expected because the older cable accumulated more road grime that protected them from the elements better and now that cars run cleaner, there isn't as much grime so the newer cables stay clean and exposed, just all kinds of neat stuff. It seemed like it would be a very interesting place to work. I looked into applying with them when I was finishing college, but they didn't need any software people at that time.

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.
