Intel is refusing to disclose serial number ranges of the fundamentally defective processors?
Followup question: How do owners of that series of CPU, who suspect theirs is one of the defective units, exchange it for a non-defective CPU before it fails?
Something similar happened a few years back with the Atom CPUs. The downside is that these were typically found soldered on expensive devices like Cisco routers, firewalls, etc. The company I was working at the time had to RMA a ton of devices that could be faulty. I thought for sure that this would result in earnings hits and lawsuits but none of that seemed to happen.
Avotons keep degrading even if you do the resistor mod to temporarily get the clock signal back within range. I had a repaired one die again a few years afterward.
I had high hopes for Pat Gelsinger too. I suspect most management expects the consequences of short-sighted corporate culture to manifest in products as maybe a 1% failure rate within 90 days of sale, not a 25%+ failure rate slowly manifesting over more than a year. The former is the cost of doing business, the latter is an existential problem. I suspect Gelsinger didn't know about it and lower management buried it thinking it was a <1% problem, and he's only found out about it as it's become clear what a massive problem it is.
When Gelsinger promised (in 2021) zettaflop systems by 2027, although there is still time, it seemed so absurdly optimistic that it is hard to trust anything he says.
However, I think people really want to give him a chance on his long term plans to make Intel competitive again.
Interesting. I bought a 13900 (non-k) in mid April this year for a new server build. It ran fine for a couple of weeks and then started randomly crashing. Having never had a cpu go bad on me before and not having another one laying around to test with, it took me a long time to figure out what the issue was. Finally, by the end of May, I had ruled everything else out and RMA’d it. The system has been running fine ever since.
I assumed I had just got a bad unit. Now I’m wondering if this might have been the cause.
Prediction: Intel is stalling the recall until after the earnings report to avoid tanking the stock.
Glad I switched to using AMD. Although some RUMINT indicating quality assurance troubles in 9000 series though. They were supposed to push out new product by end of July. But delayed to mid August.
Is there any RUMINT about specifically why it's delayed? The delay itself is not RUMINT, and it's obviously some QA issue, but beyond that?
The only rumors I've seen are generic guesses: something AMD wasn't screening for, maybe coincidence, or maybe detected after the Intel mess sent AMD's QA teams scurrying to make sure they don't have any similar issues.
It could even be a combined issue with 3rd-party motherboards with AMD's new chipsets, the combination of which they wouldn't have been able to thoroughly test much earlier.
Isn't RUMINT on the Intel problem that, even though it's nominally a chip problem, it may occur primarily due to motherboards not following guidance? For instance, if a spec says the chip and mobo should lower max voltage by 100mV under certain conditions, but the chip still sometimes requests the full original voltage under those conditions, and the mobo provides it, whose fault is that? Maybe not exclusively Intel's, depending on how the specs are documented (a classic should vs must issue).
It seems likely that small process sizes and pushing the limits of performance are going to cause more problems like this Intel one. Notice Intel didn't have this problem before they had to push their chips to compete against the high-end Ryzens.
> Isn't RUMINT on the Intel problem that, even though it's nominally a chip problem, it may occur primarily due to motherboards not following guidance?
That was merely Intel's first attempt at deflection / damage control. Kernel of truth to it, of course.
There hasn't been anything official but there were rumors about some reviewers got unexpectedly bad performance that AMD narrowed down to bad packaging for the SOC die.
If it is the SOC it doesn't have anything to do with pushing nodes as it's on a larger node and the soc itself should be a mature architecture because it's reused from zen 4
> Glad I switched to using AMD. Although some RUMINT indicating quality assurance troubles in 9000 series though. They were supposed to push out new product by end of July. But delayed to mid August.
I had a theory that the "quality issues" are a marketing ploy (see? we don't send customers bad products, unlike those other guys) combined with an excuse to delay the release date (and thus the review embargo date) until after the proposed Intel microcode release, since the updated microcode was expected to negatively impact Intel in the performance comparison.
AMD has its issues too, from time to time. I even replaced a processor through them once. As chip complexity increases, both companies are going to have these issues more often. The solution is to let other people be guinea pigs for a year.
The headline isn't clear, but the claim so far is that the microcode update will fix any CPUs that haven't begun exhibiting instability. Nothing can fix the ones that are already broken. For those that are somewhere in between, hope it fails within the warranty period I guess.
The way I understand it, they had a bug that will run the CPU on higher voltage than the hardware can tolerate.
Those who pushed the limits physically damaged their CPU and these are now cooked. The microcode update will limit the voltage, which will result in degraded performance but will prevent damage under load.
You mean everyone who owns a motherboard from a manufacturer that was given unclear guidance on power delivery from Intel, but also encouraged to make sure their boards benchmarked competitively (by providing enough voltage for clock boosts)? That's pretty much every enthusiast.
Right, so maybe a better phrasing would be: They had a design flaw and the voltage they run the CPU would actually be over the limits of what the hardware can tolerate.
Those who pushed their CPU to its maximum loads damaged their CPU physically and these are now cooked. The microcode update will limit the voltage, which will result in degraded performance but will prevent damage under load.
I don't think you intend it, but your explanations read as pushing culpability to the end user. Running Chrome, webpack, and Docker at the same time will get me to maximum load. Am I at fault for that?
The YouTube channel Moore's Law is Dead has info from Intel leakers (grain of salt) that the ring bus is most sensitive to overvoltage and is what's failing. In addition, the leakers say that with Intel's poor earnings they've been under pressure to ship higher margin parts (like a 14900K over a 14700K), and that they've been relaxing the binning standards to ship chips that barely meet the standard as 14900Ks. This is one of reasons 900K parts seem to be most affected.
In the channel's analysis, this overbinning exacerbates the failure rate as more cores require more power/voltage delivered to the common power rail the ring bus shares. This is why disabling E cores seems to help stability. This also leads him to conclude that if ring bus failure is on this knife's edge, then those who haven't experienced it likely have golden samples that fully meet the binning standards.
All of this is to say: damage has little to do with the workload you've run, and everything to do with your silicon lottery luck on the chip you got.
Level One Techs' Wendell was saying the same thing after asking companies running server farms independently. Both got some sketchily-high numbers, in the 25-50% range. This is only looking worse for Intel as days go by.
Server boards don’t mean it’s being run in-spec. The workstation boards will let you configure many parameters out-of-spec and in fact some vendors will configure them out-of-spec by default. For example W680 is definitely capable of configuring memory speeds higher than the official spec (which is only 4400 for any quad-slot board even if not fully populated!). But also things like disabling the current limiting or setting an increased or unlimited power limit.
Insofar as GN was saying that, it was because Steve was out of his depth and Wendell has had to go out of his way to correct this in subsequent interviews like the one with Ian Cutress. Not the first or the last time GN makes an innocent (or overtly malicious, in some cases) journalistic boo-boo. Not even the first problem with their coverage of this topic, in fact.
People are letting the outrage way overtake the facts here. And this includes the tech media themselves. No, it’s not in-spec just because it’s a server board with w680. Actually asus in particular was shipping with very out-of-spec defaults.
People don’t like it when IHVs keep the partners on a short leash. People literally whined about nvidia capping the voltage on Turing, for example. And then things happen (like this, or like AMD’s problems last year with chips physically exploding and deforming from over voltage) and people indignantly ask why the IHVs were allowed to do these things.
At the time people said this was utter crap, everyone knows electromigration isn’t really a big deal and takes years to even slightly affect anything, assuming it ever does at all. Like you have to really cook a modern processor, like 4.7 GHz sandy bridge for a couple years.
2-3 prompt-electromigration disasters later, it appears that maybe “the community” doesn’t actually have a particularly firm grasp of silicon aging mechanics. Or gpu costs/economics, for that matter ;)
I've been building my systems since 1999 and I've been pragmatic. Buying what was best at the time. I never had stability problems with both AMD and Intel.
That's a legitimate strategy for some Amazon trinkets but CPUs are a major purchase for most people such that they won't likely let them sit in a closet beyond the warranty period.
I would guess Intel is counting on the fact that most people are not knowledgeable enough to pinpoint a defective CPU being the issue when the computer starts crashing.
Heck, even as a SWE building my own computers for almost 20 years, I still have no idea how to properly diagnose a hardware issue when it arises. Beyond checking for explicit errors in journals/logs, and the usual memtest/BIOS update/reinstall the OS from scratch, I resort to replacing each component one by one until the issue disappears. But it's time consuming, and sometimes quite costly. I suspect most people simply replace the entire thing if it's not a prebuilt PC still under warranty.
I was similarly peeved with AMD a few years ago. There was a window of time where an AMD chip would not work with many deployed motherboards. AMD would ship you a loaner, outdated chip so you could boot the motherboard and apply the latest compatible BIOS.
Knowing this, I felt confident to purchase a certain configuration. Parts arrive and I reached out to AMD support for my loaner chip. They gave me the third degree. Insisted I provided documentation of previous attempts to reach out to the motherboard manufacturer before they would lift a finger. So, reach out to the manufacturer and say I am an idiot who cannot read the compatibility warning slathered all over their product material? I was furious at what was an obvious roadblock to not deliver on their support promise.
What a mess. Intel should be out in front of this, but they are going to kick the can down the road and hope some of the problem goes away.
No system integrator has the infrastructure to handle replacing vast numbers of CPU's and entire systems where the CPU is soldered to the mainboard and cannot be replaced.
Also, there's no way this problem suddenly snuck up on them without warning. They had customers returning massive numbers of them, but Intel kept selling defective units instead of stopping production. They absolutely knew about this as soon as problems started popping up.
A microcode patch may make it stable, but if you have a dud, you have a dud. There's no way to patch around defects in manufacturing of this nature. Microcode can reduce frequencies, but a defective part is still defective.
Unless they have specific evidence to delineate heat damage from excessive voltages and "oxidation" from a manufacturing process, then they're just playing coy at admitting their chips are burning out.
Try to avoid using it until the microcode fix in a week or two. If you bought it last week, you probably haven't used it enough to permanently damage anything from the voltage issue yet.
Keep careful watch of problems in the future: the oxidation issue for the 13th gen is a physical defect not fixable by the microcode update, but we don't know how widespread it is yet (and Intel is keeping mum). If possible, it might well be worth returning and getting a 14th gen chip, which doesn't suffer from the latter problem and the former will be fixed by microcode.
No known safety issue. Both issues (the overvoltage in both 13 and 14 gen chips, and the oxidation that's limited to 13th gen) lead to system instability. How quickly these occur is unknown from the Intel reports. Claims are as little as a few weeks, but independent verification is needed on that one.
The microcode update will probably be automatic but it might also be distributed as a bios update.
Realistically there’s no way to tell if you have an affected unit or not (Intel hasn't provided any information that would help). Nor is there any guarantee that the microcode update will prevent future issues. It appears that there is both microcode and manufacturing issues at play here.
Good question, if you set any obvious power limit in the BIOS to say 10-20% below the advertised TDP*, would that bring the actual voltages down or would it just underclock the CPU but still use the same dangerous voltages?
Or do you need to go through every obscure voltage setting and bring it down? Will even that be obeyed?
* which has no connection to the real TDP but at least it will tell the CPU ... something ...
I feel like the language is intentionally vague and intended to link the voltage issue with the oxidization issue. However, I would not feel comfortable knowing my chip may randomly become unstable way before the expected end of life.
Tell that to my 2950x, the thing is a heap of garbage...
80% of the time it won't boot at xmp memory speeds...
If it does, it trashes the pcie bus during boot...
Either way, I also had to turn off ASPM, because my nvme drives will crash during boot, or shortly afterwards...
Then there's all the random amdgpu errors it also throws, it's better with everything turned off, but the machine is basically on life support until I can build a new PC.
Zen began to be really better than the competition only with Zen 2 (Ryzen 3000), when the production of its CPU chips was transferred to TSMC.
For Zen 1 or Zen 1+, only the Epyc CPUs seem to have been free of problems.
I have a 24-core Zen 1 Epyc that has always worked flawlessly, but when I have preordered the very first Ryzen, the 1750X, I had to dump it as useless garbage after only a couple of weeks, because I was using it in Linux, where any intensive multi-threaded task was crashed by a nasty bug that was not seen on the Ryzens used just for playing games in Windows.
AMD has never given any explanation about their bug, and they did not recall their CPUs, which were completely unusable for professional purposes. However, like Intel today, they at least honored the RMA requests. However I did not bother with an RMA, especially because the procedure would have been complicated, as I do not live in the USA and I would have had to ship internationally the bad CPU. I have just dumped both the Ryzen 1750X and the expensive motherboard, keeping only the DIMMs, and then I have bought a Kaby Lake instead.
Nevertheless, I did not hold a grudge against AMD, despite losing more than EUR 800, and later I have bought an Epyc and then a Zen 2 Ryzen and then a Zen 3 Ryzen, all of which have worked perfectly.
I got a buggy 1800X, shipped for RMA to a logistics center in IIRC the Netherlands from Germany. RMA took about 2 weeks altogether and it was worth it.
Since then, I've upgraded to the new top of the Ryzen line everytime there was a significant (>40%) increase in compilation performance. The 5950X was a notable dud in that regard.
Recently, setting power limits to get 90-95% of the performance at 60% of the TDP became a thing.
Other than the chips that are significantly damaged prior to the updated microcode, why should this be treated differently from the meltdown saga? Fixes for that required significant slowdowns, except in niche applications with trustworthy code or air-gapped systems such that the vulnerability could be ignored. No Recall. Class actions ongoing, but everyone's mostly forgotten about them.
More conservative voltages will only lead to small (low single-digit) performance decreases, right? Isn't that less significant a performance hit than meltdown countermeasures? The only way I can imagine performance really tanking would be if Intel has to severely down-rate supported memory speeds as well, if the ring bus can't handle higher memory speeds at slightly reduced voltages.
Maybe off topic but I am old enough that I remember when AMD were inferior and should be avoided. It is one point in the famous "Is your son a computer hacker [1]
> If your son has requested a new "processor" from a company called "AMD", this is genuine cause for alarm. AMD is a third-world based company who make inferior, "knock-off" copies of American processor chips
I've seen multiple rumor-style explanations to this issue, including:
- it may have to do with oxidation of metallic copper deposited inside through-sillicon via(TSV)
- it may have to do with improper connection between die and substrate(that hard green plate) causing higher resistance and temperature somewhere, which is by the way the true limiting factor for socket Tjmax
- it could have to do with VCORE values used to meet the performance target being too high for the on-die ring bus logic including L1
- it is possibly related to big-little heterogeneous configuration and how voltages for big-core and little-core/uncore/IO are generated
- I've heard they had an HVAC outage in one of US fabs and it ruined some dies
- Yeah they just flew too close to the Sun, frankly
- ...
I have absolutely no skin in this game, and my question is: are there any more plausible technobabbly stories around? It all sounds intriguing to me. Some of it could be correct or relevant.

I bet they all are bad. Intel just hopes failure rate is low enough to RMA instead of recall.

Another bet: class action suits.
Something similar happened a few years back with the Atom CPUs.

At least you could fix that yourself with a resistor and a soldering iron... whatever is up with raptorlake is inside the CPU itself.
Avotons keep degrading even if you do the resistor mod to temporarily get the clock signal back within range. I had a repaired one die again a few years afterward.
Man, this really does seem like a replay of their FDIV mess (IIRC).
I was really hoping that Pat Gelsinger would restore some of Intel's respectability. This gives me doubt.

The context of what came before you: https://news.ycombinator.com/item?id=41058791 https://news.ycombinator.com/item?id=41039708
I've only ever bought Intel, mostly because I perceived them to be more stable and reliable. I think next time, I will give AMD a try.
I've been building my systems since 1999 and I've been pragmatic. Buying what was best at the time. I never had stability problems with both AMD and Intel.
Given that some reports put failure rates as high as 50% for some models/conditions this may as well be a recall.
Would almost think a recall would be easier to handle that hundreds of thousands/millions of individual RMA/warranty claims.
They're hoping a large fraction of people won't bother with the RMA process and will just shut up and go away.
Unfortunately for Intel, "away" here means "to buy an AMD processor"
That's a legitimate strategy for some Amazon trinkets but CPUs are a major purchase for most people such that they won't likely let them sit in a closet beyond the warranty period.

So, capitalism is the worst and nobody is good.
Recall likely affects shareholders so, you know, waste more time and money to ensure your corporate profits
How would a recall work, given that half of these chips are soldered onto mobos, not socketed?
What a mess. Intel should be out in front of this, but they are going to kick the can down the road and hope some of the problem goes away.
No system integrator has the infrastructure to handle replacing vast numbers of CPU's and entire systems where the CPU is soldered to the mainboard and cannot be replaced.

How PG still has a job is beyond me.
Rapid oxidation is another way of saying "burn".
Unless they have specific evidence to delineate heat damage from excessive voltages and "oxidation" from a manufacturing process, then they're just playing coy at admitting their chips are burning out.
Oxidation can also mean rust. Intel is saying that the oxidation problem and the degradation problem are separate.
I’m out of the loop. If I bought a 13700KF last week, is there anything I need to know or do? BIOS update when one is available soon?
Try to avoid using it until the microcode fix in a week or two. If you bought it last week, you probably haven't used it enough to permanently damage anything from the voltage issue yet.
Keep careful watch of problems in the future: the oxidation issue for the 13th gen is a physical defect not fixable by the microcode update, but we don't know how widespread it is yet (and Intel is keeping mum). If possible, it might well be worth returning and getting a 14th gen chip, which doesn't suffer from the latter problem and the former will be fixed by microcode.
Is there a safety issue like fire or just a “I need to buy a new CPU” issue?
No known safety issue. Both issues (the overvoltage in both 13 and 14 gen chips, and the oxidation that's limited to 13th gen) lead to system instability. How quickly these occur is unknown from the Intel reports. Claims are as little as a few weeks, but independent verification is needed on that one.
No fire. It just ruins some of the micro-electronics inside so that it won't run reliably (or at all).
Maybe just return it. Microcode “fix” is more of a band aid
and the microcode fix could means another performance impact.
like heart bleed?
You mean Spectre? Heartbleed was the SSL bug.
The microcode update will probably be automatic but it might also be distributed as a bios update.
Realistically there’s no way to tell if you have an affected unit or not (Intel hasn't provided any information that would help). Nor is there any guarantee that the microcode update will prevent future issues. It appears that there is both microcode and manufacturing issues at play here.
Good question, if you set any obvious power limit in the BIOS to say 10-20% below the advertised TDP*, would that bring the actual voltages down or would it just underclock the CPU but still use the same dangerous voltages?
Or do you need to go through every obscure voltage setting and bring it down? Will even that be obeyed?
* which has no connection to the real TDP but at least it will tell the CPU ... something ...
return it and buy amd
A decent motherboard isn't cheap.
I feel like the language is intentionally vague and intended to link the voltage issue with the oxidization issue. However, I would not feel comfortable knowing my chip may randomly become unstable way before the expected end of life.
I just wanna say that the AMD / Intel battle is cyclical and there will always be downfall of AMD or Intel.
What people ought do is just undervolt the chip by .05 at least and reduce the clock speed.

What people ought to do is get the processor they paid for.
Blacklisting Intel. We don't need them anyways, AMD already has plenty powerful chips that don't come broken.
Intel lost their engineering abilities years ago. Got eaten by sharks.
Tell that to my 2950x, the thing is a heap of garbage...
80% of the time it won't boot at xmp memory speeds... If it does, it trashes the pcie bus during boot... Either way, I also had to turn off ASPM, because my nvme drives will crash during boot, or shortly afterwards... Then there's all the random amdgpu errors it also throws, it's better with everything turned off, but the machine is basically on life support until I can build a new PC.
Zen began to be really better than the competition only with Zen 2 (Ryzen 3000), when the production of its CPU chips was transferred to TSMC.
For Zen 1 or Zen 1+, only the Epyc CPUs seem to have been free of problems.
I have a 24-core Zen 1 Epyc that has always worked flawlessly, but when I have preordered the very first Ryzen, the 1750X, I had to dump it as useless garbage after only a couple of weeks, because I was using it in Linux, where any intensive multi-threaded task was crashed by a nasty bug that was not seen on the Ryzens used just for playing games in Windows.
AMD has never given any explanation about their bug, and they did not recall their CPUs, which were completely unusable for professional purposes. However, like Intel today, they at least honored the RMA requests. However I did not bother with an RMA, especially because the procedure would have been complicated, as I do not live in the USA and I would have had to ship internationally the bad CPU. I have just dumped both the Ryzen 1750X and the expensive motherboard, keeping only the DIMMs, and then I have bought a Kaby Lake instead.
Nevertheless, I did not hold a grudge against AMD, despite losing more than EUR 800, and later I have bought an Epyc and then a Zen 2 Ryzen and then a Zen 3 Ryzen, all of which have worked perfectly.
I got a buggy 1800X, shipped for RMA to a logistics center in IIRC the Netherlands from Germany. RMA took about 2 weeks altogether and it was worth it.
Since then, I've upgraded to the new top of the Ryzen line everytime there was a significant (>40%) increase in compilation performance. The 5950X was a notable dud in that regard.
Recently, setting power limits to get 90-95% of the performance at 60% of the TDP became a thing.
I assume you haven't heard of some of AMD's 7000 chips burning themselves/exploding?
Other than the chips that are significantly damaged prior to the updated microcode, why should this be treated differently from the meltdown saga? Fixes for that required significant slowdowns, except in niche applications with trustworthy code or air-gapped systems such that the vulnerability could be ignored. No Recall. Class actions ongoing, but everyone's mostly forgotten about them.
More conservative voltages will only lead to small (low single-digit) performance decreases, right? Isn't that less significant a performance hit than meltdown countermeasures? The only way I can imagine performance really tanking would be if Intel has to severely down-rate supported memory speeds as well, if the ring bus can't handle higher memory speeds at slightly reduced voltages.
Maybe off topic but I am old enough that I remember when AMD were inferior and should be avoided. It is one point in the famous "Is your son a computer hacker [1]
> If your son has requested a new "processor" from a company called "AMD", this is genuine cause for alarm. AMD is a third-world based company who make inferior, "knock-off" copies of American processor chips

Citing an obvious satirical piece?
The only thing keeping me on Intel (for my homelab) is QuickSync. If Plex supported AMD’s equivalent I’d drop Intel in a heartbeat.
You could consider Jellyfin, it claims to support it: https://jellyfin.org/docs/general/administration/hardware-ac...
If this does not justify a recall, what would then?
Will multi CPU systems be resistant or fail if one CPU dies?
Raptor Lake doesn't support SMP, but generally a bad CPU will cause the entire system to panic/bluescreen.
I've seen multiple rumor-style explanations to this issue, including:
I have absolutely no skin in this game, and my question is: are there any more plausible technobabbly stories around? It all sounds intriguing to me. Some of it could be correct or relevant.I'm starting to want the FTC to get involved with this
