I9-12900KS very unstable constant clock watchdog timeout (Stock Settings)

[mcfaddenad]

I have just finished a new system and my 12900KS is very unstable at stock settings. At stock settings for the CPU and motherboard, I'm getting constant clock watchdog timeouts when benchmarking. I tried benchmarking with Intel XTU, Cinebench r23, and OCCT. All my benchmarks stop early due to a BSOD clock watchdog timeout. I'm unsure why the CPU is this unstable at stock. The system works fine when not under load, but once I load the system it BSODs.

Hello mcfaddenad,

Thank you for posting on the Intel® communities.

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

• Picture of BSOD if possible.
• Make sure the BIOS is updated or check with the board manufacturer if a BIOS update is needed.
• Download the Intel® SSU https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows- 

Open the application and select "Everything", click on "Scan" to see the system and device information. By default, Intel® SSU will take you to the "Summary View". Click on the menu where it says "Summary" to change to "Detailed View". To save your scan, click on "Next", then "Save". Please attach the file to your reply.

As well, please be aware that using an XMP profile with the memory speed set over the processor specifications (up to DDR5 4800 MT/s), it changes the frequencies and possibly the voltages, which are internal to the CPU. This means that the processor is being overclocked, which could be affecting the processor performance and thus, it voids its warranty, even if the cores are not overclocked.
