We are continuing to investigate with our partners the recent user reports of instability in certain workloads on these processors.

In the interim, the following BIOS settings are recommended to help maximize stability for currently installed processors while Intel continues investigating root cause:

* Please see the 13th Generation Intel® Core™ and Intel® Core™ 14th Generation Processors datasheet for more information

Intel continues to work with its partners to develop appropriate mitigations going forward. And as noted previously, if you are experiencing these issues please reach out to Intel Customer Support for further assistance.

I have made the changes.     

 

Prior to doing so, I was able to get the 14900k working (to point of entering OS) by disabling VMD (maybe it is VDM....the one where you can map pcie or SATA under it).    That got me in.   

 

The reason for the purchase of the 14900k was due to the watchdog errors I kept receiving BSODs on the 12700k which I purchased I believe mid January 2024.    All of these are running on the ASUS ROG STRIX 670 DDR4 WIFI MTHRBRD.     

 

I had gone with Puget's recommendations for Video editing in Premiere Pro.    The 14900k with the RTX4090 I figured might help encoding go blazing fast, but when not crashing, it is about the same as the 12700k .....I am encoding a video file at about the same speed on average:   ~for every minute of video content Prores HQ 422 processed it takes about a minute to process......4 hr video 30fps = roughly still 4 hrs of encode time.   January to the 12700k was after realizing a gaming chip like the i5 10700k was perhaps fast in single thread gaming applications, but not so much when needing cores.    Any guidance in that area is also appreciated.   Not sure what to say about the 12700k.   I thought it was great until the watchdog BSOD errors kept coming.     Usually resulting in corruptions and backups wouldn't fix the problem if they were also corrupted.     So on average I've had to do a full OS reinstall.....which isn't difficult except for the 100+ actually used video and sound applications.    Otherwise running 64GB 3200 DDR4 RAM and am stacked full with 4TB 990 Samsung SSDs (a couple Lexar SSDs as USBs) and given the need to restore from backups quickly, I am essentially copying a full image every 3 days of my OS SSD to an identical SSD.   BAR support is on and I did realize that unless IGPU mult-monitor was also on, the processors would not work with the Video card with regard to the encoding process.     Maybe AMD was the way as a video editor I should have gone, but  Intel has been my mainstay since DOS 3.0.    Not to mention, having to replace a board again plus ram.    So I am trying to avoid that scenario.       I am Round Rock, TX (about 2 miles away from DELL Headquarters) based and happy to collaborate on this if ever wanting a test example.    I work down at the Capital Complex for the state and it wouldn't be hard for me to swing by any Intel Austin location.    If you need log files or dump, just ask and I can include what I have.

Hello,

I have also encountered the issue on the non-K series.
I have tried both a i9-14900K and a i7-14700 both crash when I play in FHD while when I increase the resolution to 2K no problem.
So it seems that the stability problem is also present in non-K CPUs...

I should add that the crash also happens using NVIDIA DLSS UPSCALING technology.


Regards,
Matteo
