I9 12900k clock watchdog timeout

[frandan]

Hi to everyone,

I have a system with Intel i9 12900k not overclcocked on a Gigabyte z690UD (DDR4 RAM), no dedicated graphic card, Samsung 970 EVO V-Nand NVME SSD, Samsung 860 EVO 1TB as storage, 32 GB Samsung 2667 MHZ and a Coolermaster 750 W as power supply.

I usually use this system for video encoding (4k HDR) and it worked fine for about two weeks but in the last days it became very instable with very frequent  "clock watchdog timeout" blue screens.

I have changed RAM and system SSD without success.

I have reinstalled WIndows 11 and also tried with Windows 10 without success.

I have upgraded system bios to last release with a CMOS reset without success.

I have upgraded system drivers to the newest available but the situation remained very unstable.

If i try a CPU test with XTU i obtain clock watchdog timeout  immediately.

The same with memory test.

With another cpu (i3 12100) the system is stable.

What else can i try?

Thanks in advance for your answer. 

PS i attached my SSU Scan

Hello frandan,

Thank you for posting on the Intel️® communities.  

Since you mentioned that by swapping the processor to an i3 12100 the issue disappears, this may indicate that the issue is related to your i9 12900k. I would recommend you performing processing the RMA for your unit.

After verifying that your warranty is still active here, directly contact Intel Customer Support to initiate the RMA process (you cannot do this through the forums). Here are pages where you can look up contact information, including local/country phone numbers, by geography:

U.S. and Canada: Intel Customer Support

Europe, Middle East, and Africa: Intel Customer Support EMEA 

Asia-Pacific: Intel Customer Support APAC 

Latin America: Intel Customer Support LAR
