14900kf game crash and fail in CPU 1 - Prime Number test

[acbli]

When I recently used my computer to play games, I had severe random crashes on all games. At first, I didn't think it was a CPU issue, I checked everything else. For example, RAM and XMP, and reinstalling the graphics card driver. I ran memtest64 to check the memory and reinstalled WIN11, but the problem still exists.  In addition I also updated the bios and set it to default. Then reset the c++ and some dll runtime libraries. I think I did all I could except just replace the hardware. Until I started to detect CPU problems, I first used the Benchmark test that comes with Intel(R) Extreme Tuning. As soon as I run the test system, it will automatically enter BSOD and restart. Then I further used the Intel® Processor Diagnostic Tool for testing. The test results show CPU 1 - Prime Number - Fail. I found similar questions to mine in the forum, and I would like to ask if this means that the CPU is broken? Should I apply for warranty? (Interestingly, the cooling of the CPU is very good, there is no overheating problem, and there is no overclocking. But now, only when I turn on the AI overclocking mode of the ROG motherboard, some games can run normally. If the CPU is at default settings, Then all games will crash after 2-3 seconds of loading.

In addition, this all seemed to happen suddenly. Three days ago, the computer had been running normally for three months. And this only seems to crash under heavy load games, not games like League of Legends. Then I entered the product number on the box into the Intel warranty page, but the web page said my product cannot be found, is this because I purchased this CPU on another website? Should I contact them for warranty?

Just now I performed another stress test on AIDA64, and it only showed hardware failure during the FPU test. Does this almost prove that the CPU is broken?

acbli, Thank you for posting in the Intel® Communities Support.

We will be more than glad to assist you with this matter. 

In reference to your question about the Intel® Processor Diagnostic Tool resulting in CPU 1 - Prime Number - Fail, here you will find further details about this subject:

https://www.intel.com/content/www/us/en/support/articles/000094564.html

AIDA64 is a third-party tool and it could have misreadings in the results related to the functionality of the processor. We recommend to contact the developers of the application for additional information on this topic.

And yes, pretty much you tried all the troubleshooting steps we recommended for this scenario. The only thing left, if you have the option of course, will be to either test your processor on a different board or test your board with a different processor to verify the source of the problem, board or processor.

If you do not have that option, then please get in contact with the place of purchase to check their warranty policies or, you can always get in contact directly with your local Intel® department through any of our support channels to claim the warranty on your unit:

Thank you, I have successfully applied for CPU warranty. I have purchased a new CPU as a replacement. If it doesn't work, I will consider trying to replace the motherboard.

acbli, You are very welcome. Thank you very much for your reply.

Perfect, it is great to hear that you were able to replace the unit. And yes, as you mentioned, if the problem persists after that, it indicates that the issue is actually related to a different component in your platform such as the board.

Any other inquiries, do not hesitate to contact us again.
