a lot of corrected MCE errors occuring constantly on i5-12600k, but computer is otherwise stable

I was about to go to bed until my computer's terminal gave this as an output:

I tried running memtest86, memtest86+, occt and prime95 for hours at this point and I can't get it to crash or make it show an MCE error whlie running one while recording them with rasdaemon. I do however rack up a lot while just using my computer normally (playing games, rendering short videos or doing my usual work on the computer which is not CPU/GPU heavy), I racked up more than 30 in one day. I have other computers on which I have ran rasdaemon before and I have never gotten this many, ever. I am dual booting on Windows 10 and I looked through the event viewer to find that Windows complained about the same exact core and issue too. I also booted up in an EndeavourOS live cd to see if that is gonna give any MCE errors and sure enough, it did.

Hardware wise, I tried disabling XMP, e-cores, c-states, I ran intel's own cpu validaion software, I observed the motherboard for any visible damage, tried one stick of ram only, tried the other in single channel and I even removed my dGPU from my system, only to keep getting them. I will reseat the CPU one of these days and get a PSU tester and a different ram kit from a friend soon, so I can at at least scratch these variables as possible problems. I do not have friends who use the LGA1700 socket that live close to me. Thanks for the tips in advance.

And yes, the computer does not run like it should as well, which is why I am taking these more seriously than I normally would. Counter Strike 2 on Windows 10 either runs about as well as my expectations or it will drop to ~120fps for one or two minutes, only for it to come back up to where it usually stays.
Other games like Gunfire Reborn, GBVSR and Helldivers 2 run about as good as I would expect them to run on my system, but they do stutter in places I wouldn't expect them to do so. Not as serious as CS2 though.

These are my computer specs:
Nobara Linux 42 (I was on 41 when I first experienced those MCE errors for the first time)
Kernel: Linux 6.14.5-200.nobara.fc42.x86_64
Intel Core i5-12600K (never been overclocked, undervolted or overvolted)
Gigabyte B660M GAMING X DDR4 (I am using the microatx version)
2x8GB of Kingston ram at 3600MHZ 16-20-20-39-85-1.35V
Radeon RX 6700 10GB
Seasonic Focus GX-650

I have attached some images associated with me troubleshooting the computer as well.

As a point of comparison, I had rasdaemon running on my Ryzen 5 5625U laptop while using it like I would my i5-12600k pc and it reports no MCE errors at all. It's running Arch Linux. These are the errors only from today (the 07.05.2025) when entering "sudo ras-mc-ctl --errors" on my i5-12600K system.
All of these were caused while my computer was idling or running a computer game like GBVSR and Gunfire Reborn, both light games:

Hi @crsorsmth,

Thank you for sharing this information. I will begin investigating the issue. I'll post an update here or notify you directly once there are any developments. If I need further details, I'll reach out to you here. I appreciate your patience as I work on this matter.

Hi @crsorsmth,

A Machine Check Exception (MCE) is a type of error detected by your computer's processor when it encounters a hardware problem.

To effectively diagnose and address the issue you're experiencing, I kindly ask you to provide detailed responses to the following questions. This information will help us isolate the problem and determine the most appropriate course of action.

When did you first start noticing the MCE errors?
Have you made any recent hardware changes or upgrades to your system?
Have you checked the system temperatures to ensure the CPU is not overheating?
Have you updated the BIOS and all relevant drivers to the latest versions?
Is the power supply unit (PSU) providing stable and sufficient power to the system?

If you encounter an MCE error, it's often a sign of faulty or misconfigured hardware. You may try the following recommendations on this articles:

Overheating Symptoms and Troubleshooting for Intel® Boxed Processors

Troubleshooting Tips for Random System Crashes on an Intel® Boxed...

Regarding to the other issues: (Gunfire Reborn, GBVSR, Helldivers 2): Generally perform within expected parameters but encounter stuttering in specific scenarios. Please submit or post a new thread for each game as we can only accommodate one issue per case.

I look forward to your response and am committed to resolving your issue promptly.

Warm regards,

Randy T.

Hello, thank you for your response.

1. I first noticed them on the 3rd of May, but it occured to me shortly after writing my first post here, to do a "journalctl | grep mce" fetch with my terminal. I noticed that I have been having MCE reports everyday, ever since I installed my current Linux on this machine. I hadn't gotten any of the stutters I mentioned in my first post until recently (around mid April, I never saw them as alarming) and Linux did not notify me about those MCE reports either until the 3rd of May, so I can't say how severe they were back then compared to how they are now. I did not have Linux installed for a few months prior to this Linux installation, but I did have Windows and it never warned me about cache hierarchy problems.

2. No. Last time I changed anything on the inside was in 2023. I have unplugged or reseated some parts since then, but just for maintenance, to get rid of dust and so on.

3. Yes, I forgot to mention this in my previous post, the CPU is running cool during operations. It does not reach anything higher than 50°C during gaming sessions and during stress tests, it hovers around 60-70°C, depending on the workload. Prime95 brings it to 70°C, OCCT brings it to around 65°C. I have an image attached.

4. Excuse me again for failing to bring this up. I did update the BIOS upon noticing all these corrected MCE errors. I was previously running on F28 and I upgraded to F31. It did not help unfortunately. I am using the Gigabyte B660M GAMING X DDR4 (microatx version)

https://www.gigabyte.com/de/Motherboard/B660M-GAMING-X-DDR4-rev-1x#kf - just in case, here's the link to my motherboard

5. The power supply should be more than sufficient. I had plans to meet up with a friend who has a PSU tester, but things got in the way. I do not know if this helps, but at the very least, I can say that running the system with the minimal amount of components, does not help the situation. I took out the GPU, kept only one stick of ram and ran it on standard ddr4 speeds, took every SATA drive I usually have hooked up, removed my wifi card and only had a basic keyboard attached. The errors still persisted. And I have never had any random shutdowns or anything typical leading to a PSU defect.

However I do want to bring up a few new discoveries I have made.

The computer does not error out a single time while running any stress test or when it's completely idle. Be it Prime95 on the blend option, smallest FFTs (tests L1/L2 cache) or the small FFTs (tests L1/L2/L3 caches), then it simply refuses to error out. Same story with every other stress test I ran on the computer, such as OCCT, Intel Validation's Tool or Stress-ng. Errors occur only during light operations like web browsing, communicating through Discord, Cisco Packet Tracer and light games such as the ones I already mentioned. I also left it running at idle while I was away from home and after 5 hours of runtime, no new errors had occured.
With this in mind, I ran Cyberpunk 2077 and Helldivers 2 to see if I would get any errors in those games, they do max out my CPU. And sure enough, after running the benchmark of Cyberpunk 2077 multiple times and playing Helldivers for a good while, none of those errors occured while either of the two games was running on the computer. I am starting to believe that my CPU really is not failing, but I still cannot comprehend what exactly could be happening.
Also, since I have one month left of warranty on the CPU, does this lead you to something worrying like a defect, or are you sure that it is a case of misconfiguration or something as minor? I am mostly asking just to know if I should take more advanced courses of action.
One last thing on the topic of stability, can those errors lead to file corruption if they go uncorrected? I know that defective RAM can do this, so I am curious if the L1 cache of the CPU can get this destructive.

Anyways, I also decided to take pics of HWInfo stats while Prime95 (blend) was running on Windows 10. I could not get readings as reliable as HWInfo on Linux, but I also did not have the most of time to research this topic, so if you know good software for me to use in place of HWInfo but on Linux, make sure to let me know! I will look for something on my own in my free time too. If I come around a good piece of software, I will just reply and send more pics of the voltage my pc is running on. I am sending them mostly because I am not an expert and I am prone to missing out on things that may be obvious to others who know more.

Thank you in advance!

Hi @crsorsmth,

Thank you for your detailed response and for the extensive checks you've conducted on the hardware components. It seems you've thoroughly ruled out the possibility of defective components. Based on your observations, the next step I recommend is reinstalling the operating system. Since the issue began after Linux was loaded onto the system, it's worth investigating whether the Linux kernel is conflicting with the overall system configuration.

Additionally, you might consider testing the CPU by swapping it into another motherboard or system to see if similar Machine Check Exceptions (MCE) occur after the swap test. This can help isolate any potential issues with the CPU cores. I will also attach a download link for software that can help determine if there is anything wrong with the CPU. You can also use Intel's Extreme Tuning Utility (XTU) to check the CPU cores and performance.

Intel® Processor Diagnostic Tool

The Intel® Processor Diagnostic Tool Overview, Download, and...

Intel® Extreme Tuning Utility (Intel® XTU)

While you have tested the system using third-party applications, please note that we typically rely on our own software designed for Intel chips. However, we respect the use of third-party tools, as many users and gaming enthusiasts, like yourself, find them valuable.

Please feel free to share screenshots of your observations and findings here once you've completed these steps. This will allow us to begin looking into the issue more closely. I appreciate your efforts and look forward to your response.

Warm regards,

Randy T.

Greetings,

excuse my late response, I simply have nothing new to report. I have some new remarks, but nothing concrete. At the very least, I can report that the system is still very much stable on the surface. I have been using it like I usually do for the last few days and it has not let me down. There have even been periods where hours had passed without a single MCE report happening.

Things I did in an attempt to fix the MCE reports:

I used the software you mentioned. I tried stress testing with Intel XTU and nothing tangible came out of it. Could not do a whole lot with the sliders, but I would assume it is because of my B660 motherboard. I also tried the validation program, ran in a loop 40 times and no errors came out of it.

Remark:

However one remark about this whole experience was that my CPU can't reach its turbo boost clock of 4.9ghz on Windows at all. It reaches it very frequently on Linux, but never on Windows for some reason. Tried reinstalling the drivers already, played around with the BIOS settings (voltage, boost clock behaviour settings and so on) and I cannot get it to do that. I got rid of the turbo boost altogether and it still errors out on Linux and once again, only during light tasks or light gaming. The fact it behaves right on Linux still leads me to believe that it is caused by a poor installation of Windows or drivers. End of remark.

However, my friend and I finally got around to testing the PSU with a tester. The values returned normal, even after letting it run for a while. We have not tried it in a separate system, because that would take us too long, and because frankly, I do not suspect the PSU to be the problem.
I also have not tried running the CPU on a separate motherboard or a different CPU on my motherboard. Do not have the means of doing it exactly now, and I was never planning on getting another LGA 1700 CPU. I will try to win an auction on a cheap LGA 1700 CPU, it was one of the pentiums, but I keep looking for more. Unfortunately, none of my friends are on the LGA 1700 socket, so I can't just get a different CPU from them.

And about installing a different OS on it, I already tried a different Linux distro, I tried EndeavourOS and it had MCE reports already in the LiveCD environment. If I run out of things to do, I will end up formatting the partition of my current Linux, but for the time being, I see not reason to do so.
And Windows hasn't reported any CPU errors since last time actually. I will actually switch to Windows 10 for now to see if I can observe anything weird remarks like the one I mention on the paragraph below.

Remark:

I realized that my pc clicks when it errors out, but very rarely. I actually noticed this from the first ever MCE error I got, but I thought it was the hard drive, so I dismissed it. However, just yesterday, I knew for sure I heard a weird click that doesn't really correspond with what I would usually hear from my hard drive, so I reacted fast. And sure enough after inputting "ras-mc-ctl --errors" there was a corrected error that had happened seconds ago, like 10 seconds ago. I tried triggering it and then listening closely to the computer, but all I could observe was just usual coil whine from my CPU or VRMs that have always been there since the very beginning. Not sure what to make of this click that I heard, but it did seem to correspond to the MCE report. End of remark.

With all this, sadly my time is running out. I am going to be out of town for a good while in less than two weeks and I would not be able to do any testing on the PC during that time. Unfortunately, the timing is very poor as the warranty period for both my CPU and motherboard will be ending next month too and I do not think I will be back before it ultimately ends. With this, I want to know, if I request an RMA for my CPU, will I have to pay for shipping, if the CPU turns out to be fully functional? If it is all covered by you guys, I would not mind sending it just to be safe. Keep in mind that none of the validation software you provided me with errored out, so I am not confident that the RMA will result in anything other than wasted time for both you guys over at Intel and me. So I would like to hear what you think about this course of action.

Other than that, I have nothing else to say. Thank you for your dedication on the matter!

Warm regards.

EDIT: I have attached the (so far) only error report I got on Windows. It was hidden deep in the event viewer. I unfortunately only have a photo taken from my phone with it and it is in German. The report is now gone, I did not know that Event Viewer deletes past entries, so my bad on this front.
The error was corrected,
it was reported from a core of the CPU (much like how it is on Linux),
the source is unknown,
the type of error is "Cache Hierarchy Error" and the processor APIC ID is 32.
It also tells me that there is more information to be found in the advanced tab, but there was just one more additional entry as far I recall. I remember it was something in the lines of "0x0000008", not sure how many zeroes it had. I thought I took a pic of it, but I have seemingly not.

Hi @crsorsmth,

Thank you for your detailed response. I appreciate the thorough investigation you've conducted on your end. Based on the software tests you ran and the results obtained, we can initially conclude that the CPU is not faulty. Concerning the frequency issue it's important to note that processors do not operate at their maximum frequency constantly; they automatically adjust to the optimal frequency based on workload demand. If the demand is high and there are no physical constraints, the processor may run at or near the turbo frequency.

In my personal opinion, the differences between Linux and Windows in terms of initialization could be contributing to the frequency readings you're observing. You can find more information on this topic in the articles I've attached.

I understand that swap testing with a different motherboard or CPU may not be feasible due to availability. However, conducting such tests could help us accurately identify the root cause of the Machine Check Exception (MCE) error, as we are currently uncertain about its origin.

Regarding the noise you mentioned, it's important to note that the CPU itself cannot generate noise, as its components are not capable of doing so. The noise you're experiencing is likely "Coil Whine," which originates from the inductors on the motherboard, graphics card, or power supply. You can explore possible workarounds in the article I've attached.

Why Is a High-Pitched or Whining Noise Coming from Computer CPU...

For warranty options, I've checked your area, and the only RMA we can offer, if applicable, is a standard warranty replacement if the CPU is indeed faulty. You can find more information and create a ticket using the links provided.

Lastly, I investigated the error message you provided. While it's somewhat unclear, I'm not entirely certain it's a CPU issue, as other factors may contribute. Error code 0x0000008 indicates a Cache Hierarchy Error, typically related to issues within the processor's cache system, affecting performance and stability. The APIC ID 32 refers to the specific processor core that encountered the error. Common causes include hardware faults, overheating, power supply problems, or software conflicts.

To summarize, I believe swap testing is the best step we can try, if possible, with either the motherboard or CPU. I hope this information is helpful. If you need further assistance, please do not hesitate to respond to this thread. I look forward to your response.
