Need Help on CPU Instability

[Dhanesh9397]

I have a laptop with Intel Core i9 14900HX CPU and have faced stability issue 2 months ago. I did research many laptop consumer globally are facing with this issue as well.

I experiences games / apps crashes during high load or shader compilation with the following error:

1. "Access Violation" 0x000005 with NvGPUComp64.dll, especially during game background shader caching
2. BSOD CLOCK_WATCHDOG_TIMEOUT

I have contacted laptop manufacturer on this issue, and they are aware of 13th gen and 14th gen Intel Core CPU instability issue, and have replaced the mainboard (CPU + GPU) as my device still covered under warranty. Currently, I am not experiencing any issues after Mainboard (CPU + GPU) replacement. However, I am concern on about potential future occurrences for this issue as other users reported that they have done mainboard swap for over 3 times due to same CPU related issue. The current BIOS in my system is latest with old microcode patch 0x129.

The main bring up of this matter is to highlight the following:

1. Suspect 13th and 14th Gen Intel Core Mobile HX CPU are also likely affected with instability issue (based on my device issue and global users reports)

2. Laptop manufacturer are not align with Intel on latest delivery on microcode patches (0x132) via BIOS update.

Appreciate for any advice / help from your team about this, as I receive poor outcome from any I feedbacks to manufacturer support team to contain this problem.

Hello Dhanesh9397,

Thank you for posting in Intel Communities and for

I want to acknowledge your concerns regarding the stability issues you encountered, including the access violations and BSOD errors. I'm glad to hear that the mainboard replacement has resolved the immediate issues for your system.

Regarding the 13th and 14th Gen processor instability, I'd like to clarify Intel's current position: Based on our analysis of the reported Intel® Core™ 13th and 14th Gen desktop processor instability issues, Intel has determined that mobile products are not exposed to the same issue. However, I understand your concerns given your experience and the reports you've mentioned from other users.

Given the specific details you've provided about your HX-series processor and the symptoms you experienced, I will further check on this matter. This will help ensure we have a complete understanding of any potential issues that may affect mobile processors. I will share an update with you once our investigation is complete and additional information becomes available.

Thank you for taking the time to report this issue and for your patience as we look into this matter further.

Best regards,

JeanetteC.

Hi Intel Support Team,

Thanks for the reply. I would like to point out that I have did some testing on my own and document some valuable logs and shared to Manufacturer community support before the warranty support. Therefore, I would like to share the details to your team as well.

Refer to the link for my post to manufacturer community forum. At the end of my post, you will find the attached zip files for the crashes and logs.

Hope this will help your team further.

Thanks.

Hello Dhanesh9397,

Thank you for reaching out and sharing your detailed testing documentation and logs from the Acer community forum. I appreciate the time and effort you've put into documenting these issues. However, I'd like to share some important information regarding Intel® Core™ 13th and 14th Gen processor instability issues:

Based on Intel's comprehensive analysis of reported instability issues, mobile products are not exposed to the same Vmin Shift Instability issue that affects certain desktop processors. This is documented in our official community post: https://community.intel.com/t5/Mobile-and-Desktop-Processors/Intel-Core-13-14th-Gen-Instability-Update-Future-Products/td-p/1627440

Unaffected Products Include:

• Intel Core 13th and 14th Gen mobile processors (including HX-series processors like your i9-14900HX)
• 12th Gen Intel Core desktop and mobile processors
• Intel Core 13th and 14th Gen i5 (non-K) & i3 desktop processors
• Intel Xeon processors
• Intel Core Ultra (Series 1) processors

While your i9-14900HX is not affected by the known Vmin Shift issue, the crashes and BSODs you're experiencing still warrant investigation. I'll review the logs and crash data you've provided in your Acer forum post to help identify the root cause of these stability issues.

Thank you again for the comprehensive documentation - it will help us better understand what might be causing these problems with your system. I'll post an update once it is available.

Best regards,

JeanetteC.
