WHEA-Logger Event 19

[DTB1337]

• Operating System: I have performed multiple fresh Windows installations.

• BIOS/UEFI: I have updated the BIOS to the latest version.

• Driver Installation: I frequently encounter Blue Screens of Death (BSODs) specifically during graphics driver installations, which further points away from the GPU itself.

• Cooling: I have replaced the CPU cooler and reapplied thermal paste multiple times, consistently monitoring temperatures to ensure they are within normal operating ranges.

• No Overclocking: My system is running at stock speeds for all components; I have not applied any overclocking.

• GPU Tests: I consistently encounter WHEA errors during the GPU Variable test in OCCT. Crucially, I have tested this with two different graphics cards (my original Intel Arc A750 and a separate NVIDIA GeForce RTX 5060). The error persists with both GPUs, unequivocally ruling out the graphics card itself as the primary cause.

• CPU Tests: I ran comprehensive CPU stability tests in OCCT, and no errors were detected.

• RAM Tests: I performed thorough memory tests using Memtest86. I tested with both my original RAM configuration and with newly purchased RAM (32GB DDR4 3200MHz (16x2) and 64GB DDR4 3600MHz (16x4)). In all configurations, including testing with and without the XMP profile enabled, Memtest86 found no errors, indicating the RAM is not the issue.

• Power Supply Unit (PSU) & Cabling: I have also systematically ruled out the power supply. I've replaced the PCIe power cables connecting the PSU to the graphics card and even tried a completely different, known-good PSU. The WHEA errors continued to occur under GPU Variable test load, confirming that the power supply and its cables are not the root cause.

Hi DTB1337,

Thank you for reaching out to the Intel Community Forum. To assist us in investigating the issue, please provide the following details:

• When did the issue starts?
• Did you do recent changes with the system?
• Is there any physical damage?
• Are you using Intel Default settings?
• Does the issue still occur on both processors?

Additionally, to gain a comprehensive understanding of your system, please use the System Support Utility (SSU). This tool will generate a text file compiling all your system information. You can follow the instructions at this link and send the text file here. Help Guide for the Intel® System Support Utility.

If you have any questions, please let us know. Thank you.

I have contacted support via email. If there is anything further, I will write an explanation again.

Let me answer your question first
- I don't know when or where it happened
- I don't know if anything is damaged or not, but everything seems normal to me. I've never dropped or hit anything. I've worked in computer assembly for many years. I know the basics of how to assemble correctly, so I don't think any parts are damaged from the assembly.
- I didn't overclock and set everything to default. I have RAM that I use XMP profile, but even if I turn off XMP profile, it still has problems.
- I don't have another CPU because I sold it.

I want to update more.
I tested on Intel PDT 64 4.1.9.41.W.MP Everything looks normal
Now the problem is
Event Viewer notifies WHEA Logger 19
Reported by component: Processor Core
Error Source: Unknown Error Source
Error Type: Cache Hierarchy Error
Processor APIC ID: 40

And

HWINFO64
reports CPU Cache L1 Error

And

In OCCT
reports WHEA Error from GPU test whether 3D Adaptive or VRAM test
