erstrauss — Sun, 25 Apr 2021 02:47:09 GMT

Hi All,

My system:

1. I'm running with default setting
2. CPU is not getting hot, up to 55C
3. the dmesg command output includes:

[93947.269384] mce_notify_irq: 2 callbacks suppressed
[93947.269387] mce: [Hardware Error]: Machine check events logged

my questions:

1. Are the above errors in dicate CPU issue or RAM issue.
2. What are the next steps to isolate it, and fix the issue?
3. What diagnostics tools evailable to isolate the root cause of the issue?

I'll appreciate your help.

Thank you.

Hello erstrauss,

Thank you for posting on the Intel® communities.

In order to better assist you, please provide the following:

1. Run the Intel® System Support Utility (Intel® SSU) to gather more details about the system.

· Download the Intel® SSU and save the application on your computer: https://downloadcenter.intel.com/download/26735/Intel-System-Support-Utility-for-the-Linux-Operating-System

· Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".

· To save your scan, click Next and click Save.

2. Do you receive the same errors or similar on Windows?

3. Have you tried reinstalling the operating system?

4. Have you performed any troubleshooting steps?

5. Is this issue recent or old?

6. Are you presenting issues with your computer? Ex: performance, low FPS, crashes, etc

Regards,

Deivid A.

erstrauss — Tue, 27 Apr 2021 00:02:51 GMT

Hi Deivid A,

Thank you for your reply.

1. Please see attached ssu output from the system, the files are a bit different as I installed additional packages which are mentioned in the script.

2. This box doesn't run Windows.

3. I installed the OS, and keep the kernel updated, I can run any other linux from live-usb-stick if needed, please suggest.

4. Yes, I looked in the ia32 architecture books, and tried to decode the Status, which got me to post this question.

I can switch the DIMMs but I suspect it is not a RAM issue.

5. The box was build early January, and was tested memory tester and passed the 24 hours run,

Checking the systems logs, I see the Machine check event, from January 19.

So it seems that it was never running without this event.

6. The system did crashed few times, and some applications get segmentation fault on instructions that do not access memory, like xor %rdi, %rdi or lea.

Other than that it works ok and no other issues.

I'll be happy to run any stress application to test it.

Please let me know if more information is needed.

Thank you.

Hi Deivid A,

In order to verify that it is not OS specific, I booted the system to Intel-Clear-Linux usb.

I ran the following commands to cause the system to generate these errors,

git clone http://github.com/erez-strauss/lockfree_mpmc_queue
cd lockfree_mpmc_queue/
make -j
make report

while running the 'make report' command, I got the following event, again:

DeividA_Intel — Tue, 27 Apr 2021 21:01:53 GMT

Hello erstrauss,

In order to help you further with the issue, I would like you to provide/try the following:

1. Have you overclocked the processor? Or have you taken it above the base frequency? (Processor Base Frequency 3.60 GHz)

2. Have you enabled Intel® Extreme Memory Profile (Intel® XMP? If so, try to disable it or choose the frequency supported by your CPU (2933 MHz)

3. Have you checked with Asus for any possible compatibility issue with the Linux family?

Troubleshooting steps:

1. Try a minimal configuration. CPU> 1 stick of ram> no video card

2. If possible, try with a different CPU or RAM.

3. Try a clear CMOS or BIOS recovery. You may need to check with Asus for the steps.

4. If possible, take the computer to a repair store.

Best regards,

Deivid A.

Hi Deivid,

Thank you for your follow up. Sorry I had few busy days.

The current system runs without graphic card, and uses the on chip graphics.

Yes, I tried plugging out one of the 16GB DIMM, moving the DIMM to different sockets, and retested - seeing the same machine check events.

next I'll try: resetting the BIOS, but it doesn't seems the issue.

1. I did not overclock the CPU or memory; should I play with the cpu/memory voltage or clock?

2. The computer was built from its components (CPU, RAM, MB, Fan, NVMe, PSU, Case). If I take it to a store, I would like to know what should I tell them to replace - which brings me to the question: is it CPU or RAM.

3. Is it possible that some of the default setting of the MB, place the CPU / MEM outside of the recommended zone?

4. Is there any stress/diagnostics program that I should try? for reproducing the issue and getting more detailed information.

5. If there are more diagnostics tools on Windows, I might boot a windows USB, and test it.

Thank you,

ErStrauss

What is the exact model number of your DIMMs? Did you try disabling XMP?

Re: HW Error i9-10850K - Is it CPU or RAM ?

erstrauss — Sun, 02 May 2021 03:27:02 GMT

The DIMMs:

Corsair Vengeance LPX DDR4
CMK32GX4M2E3200C16
DDR4 32GB(2X16GB) 205100197520892
3200MHz 16-20-20-38 1.35V ver 3.44

Re: HW Error i9-10850K - Is it CPU or RAM ?

erstrauss — Sun, 02 May 2021 04:47:54 GMT

Hi Deivid an Scott,

I cleared the CMOS and chose intel default settings.

I tested with each of the DIMMs and I get the same error.

Which leads me to the following options:

1. MB BIOS chooses wrong memory or CPU timing configuration.

2. CPU issue.

3. DIMM (both of them) have the same issue?

My next steps:

BIOS upgrade, just release few days ago.

Are there any other directions / testing I need to do?

How would you recommend to get the system to a stable state.

Please advise

Thank you for your help,

ErStrauss

Re: HW Error i9-10850K - Is it CPU or RAM ?

I upgraded the BIOS, no change, still same errors.

Re:HW Error i9-10850K - Is it CPU or RAM ?

DeividA_Intel — Mon, 03 May 2021 20:09:36 GMT

Hello erstrauss,

Thanks for the information provided, and I would like to let you know that there is no need to play with the CPU/memory voltages since this could damage the CPU and/or the motherboard with the time.

Also, I would like you to try the following:

1. If you are willing to use Windows, try to check if you have the same performance issue with Windows.

2. With Windows, use the Intel® Processor Diagnostic Tool to check if the CPU is defective:

- https://downloadcenter.intel.com/download/19792

3. You can explain the situation in the repair store and ask to run a diagnostic focusing on the CPU and RAM.

4. Make sure that the RAM is running at 2933MHz and the CPU at 3.60 GHz.

If you noticed any error with the Intel® Processor Diagnostic Tool, save the results and send them in your next post.

Best regards,

Deivid A.

-------------------------

Interesting note:

When I set the DIMM frequency to 2933MHz, and ran with a single DIMM, the benchmark application did not triggered the hardware event.

When I ran it with two DIMMs at the same frequency - I got the hardware event as before.

I'll continue testing it with linux and / or windows.

I need to get to a stable system.

Please suggest next steps.

Thank you,

Re:HW Error i9-10850K - Is it CPU or RAM ?

DeividA_Intel — Wed, 12 May 2021 19:21:53 GMT

Hello erstrauss,

Thanks for the information, based on the previous test this looks like an issue related to the motherboard (RAM slots) or CPU (memory controller hub), but to be completely sure I recommend you try with different hardware:

1. Use a new RAM with your current system or use the same RAM with a different setup.

2. Try a different CPU on your current system or try the same CPU with a known working setup.

3. try with a different motherboard and use the same RAM and CPU that you have.

Also, you can take the computer to a repair store for them to run the previous tests, however, this may not be for free.

Best regards,

Deivid A.

Hi Deivid,

I replaced the CPU with another i9-10850K, I replaced the DIMMs with Crucial 32GB, and got the same errors.

Hi Deivid,

Attached are the logs from the system with different CPU and different RAM, running ClearLinux.

Same error reported with and without the NVMe storage ( I booted linux from USB drive ).

Thanks
