I am only aware of 2 examples, the one that was posted on reddit and is now apparently being shipped to GamersNexus, and Der8auer, who didn't even notice pad discoloration (so may not have even been caused by an overcurrent event).
I wouldn't bet their "fast" response is due to them internally already knowing, so much as the PR hit from getting to the top of the PC enthusiast forums on reddit. None of the statements so far even suggest they've reproduced anything wrong, leaving vague statements of investigating it or adding more limitations in case that was an issue.
I remember a while ago something similar happened when someone read a lot into a comment into the open source AMD GPU driver as the "Shader Prefetch" feature of their GPUs was broken and disabled. AMD ended up having to issue a statement saying it's enabled and working where it benefits performance - and that shot to the top of those same forums and people "demanded" an explanation, and that was just an internal detail of hardware performance, not even a user-visible feature. To this day some commenters think the performance is somehow hobbled by this, so there may be more pressure to get faster responses.
I personally work on GPU drivers, AMD GPU drivers, but not on windows. I actively avoid commenting on things I have personal knowledge of, so I don't accidently leak something, but also because I see so much /wrong/ stuff repeated on the internet. In fact, I would say the majority of the specifics that are "generally accepted" on those subreddits are wrong to the point of being misleading. And a couple of times I've tried to question things I knew were incorrect I was heavily downvoted and dogpiled, so I gave up.
So while I have no direct knowledge of anything related to the CPU and it's power management, I'm trying to avoid Gell-Mann amnesia on "facts" repeated in those same subreddits.
So my current position is there may be an issue here, it may even be related to the SoC voltage regulation currently being blamed, but the "evidence" so far could also be caused by a thousand other things.
- ChoGGi 4y agoIn summary you're saying it's caused by GPU drivers. /s
- JimBo72 4y agoThe four motherboard makers that have issued public press releases about revised firmware that is designed specifically to limit the SoC voltage to prevent failures would disagree with you here. If that isn't a public admission of this being the source of the failure, what is?
- iLoveOncall 4y agoFour motherboard makers jumping on the FUD train isn't proof of anything.
- JimBo72 4y agoAMD has now specified that the issue is SoC voltage in a follow up statement. https://www.tomshardware.com/news/amd-issues-follow-up-statement-on-ryzen-burnout-issues-limits-soc-voltages https://www.tomshardware.com/news/amd-issues-follow-up-state...
- simplotek 4y ago> The four motherboard makers that have issued public press releases about revised firmware that is designed specifically to limit the SoC voltage to prevent failures would disagree with you here. What I'm seeing is four motherboard makers trying to win customers at the expense of ASUS by taking very public steps to state their product does not suffer from this issue unlike ASUS.

- kimixa 4y agoAnd I personally have an 8700k in my home machine. I work in a large company, I'm not really involved with anything or anyone working on CPUs. I have no internal knowledge of anything in this area. And I'm just pointing out how the statements of evidence presented here don't naturally lead to this conclusion as seem to be implied - not that this conclusion isn't correct, or some opinion about the quality of the hardware and software involved. I'm trying my best to not involve my opinion, and instead actually stick to the known facts. Which is my issue with this story as written. I'm not sure if you're reading the same statements, but the ones I've seen explicitly don't admit fault.
