Update of my previous issue thread on u7 265k which now I found the solution of

[LR_Daring]

The previous thread is here: Re:my ultra 7 265k platform experiencing NPU issue and Blue Screen on starting - Intel Community

About the NPU issue, intel's official stuff told me to set everything to default, it did solve the issue but the cost is high and it does not worth it.

Recently I've been told that there's another solution, which did solve my issue, once for all.

Let me repeat my issue here:

(I was and I am using the latest NPU driver from intel official as well as Windows11 23H2)

When XMP of 8000c38 hynix new Mdie enabled, integrated graphics and NPU are somehow unable to work together. I got a "Windows has stopped this device because it has reported problems.(Code 43)" when I enable integrated graphics in that case.

How did I solve the issue without setting everything to default or disabling XMP?

I was told by a friend to install a special NPU driver that supposed to be used on Dell's product, it's here:英特尔 AI Boost 驱动程序 | 驱动程序详情 | Dell 中国

To be clear again —— I am using DIY desktop hardwares, nothing is OEM and nothing's from Dell.

After installing this driver, my issue solved. Integrated graphics and NPU work well with XMP enabled.

Why do I wanna update and post my experience again?

Well, I'd like to warn intel: there must be something wrong with this gen of Core CPU or NPU drive according to what I experienced.

What's more, I was also told that this issue happens not only for those who has integrated graphics like me(u7 265k), but also for those who doesn't have integrated graphics (e.g. u7 265kf, etc).

Intel has got to look deep into this or maybe, just contact to Dell and see what's going on. That's quite disappointed for me to have such a product experiencing.

Hi, LR_Daring.

Thank you for taking the time to follow up and share your findings in such a detailed and structured manner. Your persistence in troubleshooting and ultimately identifying a workaround using the Dell AI Boost driver is both commendable and incredibly insightful for our technical escalation path. Clearly, for users running high-performance memory like Hynix 8000MT/s CL38, this is not a sustainable or acceptable long-term solution. Your successful use of a Dell-specific NPU driver on a DIY system points to a potential compatibility or validation gap within the current driver stack that warrants deeper analysis. I would like to proceed with the following

1. Could you provide a System Support Utility (SSU) report from the affected system? This will help me evaluate BIOS settings, driver versions, and hardware context holistically.
2. Did you encounter any BSOD error codes or bug checks prior to installing the Dell driver? If so, please share any minidumps or logs available.
3. Have you tested the system under sustained workloads (e.g., AI workloads or GPU compute) since installing the Dell driver? I’d like to know if the solution holds up under full load conditions.

Best regards,

Von M.

1. Attachment fb.txt uploaded.

2. No, nothing.

3. I'm not a pro here so I'm not sure, but I can offer some information for you to help anarlyse:
I tried “benchmark_app -m models/intel/face-detection-adas-0001/FP16/face-detection-adas-0001.xml -d NPU -nireq 1” by python, its output is in the attachment npu bench.txt I uploaded. Key part might be

"

[ INFO ] Compile model took 1019.05 ms
[ INFO ] First inference took 75.92 ms

"

and

"

[ ERROR ] Exception from ...
ZE_RESULT_ERROR_DEVICE_LOST
code 0x70000001 - device hung, reset, was removed, or driver update occurred

"

I also tried Geekbench AI with OpenVINO, it provided an instant load on NPU but later showed an error of "Internal error code: 0x0f00580f", I'm not sure if it's because I operate wrongly or it's unstable.

[VonM_Intel]

Hello, LR_Daring.

Thank you for providing the detailed information and the attachments. Based on your output and the error messages you've shared, it seems like the NPU is encountering issues under certain workloads, potentially related to device stability or driver compatibility. The "ZE_RESULT_ERROR_DEVICE_LOST" error you encountered during the benchmark test suggests that the device may be getting disconnected or losing communication with the system during processing, which can be caused by driver instability or a hardware issue. The error code from Geekbench ("Internal error code: 0x0f00580f") might indicate an issue with the NPU's handling of certain operations or workloads, and it could be related to a misconfiguration or instability in the driver or hardware.

In the meantime, I’ll need to conduct additional research on this issue and will post an update in this thread once I have more information about this matter.

Best regards,

Hello, LR_Daring.

Thank you for your patience as I work to resolve the issue you're facing. To further isolate the problem, could you please check if you have attempted to install the Intel® NPU Driver from our website? You can download the driver using the link below:

Download Intel® NPU Driver

If you need guidance on how to install or update the driver, I recommend referring to our helpful article:

How to Install or Update the Intel® NPU Driver

Additionally, it’s worth noting that it is unusual for a DELL driver to resolve this issue, especially since you are not using a DELL system. This suggests that the problem may lie elsewhere, and installing the official Intel® driver could help address it. Please give this a try, and let me know how it goes. I'm here to assist further if needed.

Best regards,

Von M.

I did and I just did some more again.

There's a new discover —— I tried different version of intel's official NPU driver from 32.0.100.2714 to the latest(.3967).

Only version 3104 makes the NPU work, all others encounter Code43 and not work at all.

Meanwhile, the driver offered by Dell is the same version - 32.0.100.3104

So it's not about Dell, it's about driver version 3104

[VonM_Intel]

Hello, LR_Daring.

Thank you for the update, and I truly appreciate your continued diligence in testing and sharing these insights. It's very helpful to know that only version 32.0.100.3104 of the Intel NPU driver successfully enables functionality without triggering Code 43, while other versions, including the latest releases, continue to present issues. Your observation that Dell’s provided driver aligns with this same version further reinforces that the behavior is indeed driver-specific and not OEM-related.

As a next step, I recommend testing the latest version of the driver under a variety of conditions to help me better isolate the issue. Please try the following:

• Test with Different System Loads: Run the system with various applications running in parallel to observe how the driver behaves under different workloads.
• Modified BIOS Settings: Test with different BIOS configurations, such as adjusting C-States, enabling/disabling Overclocking, and using Default settings to see if any configuration changes impact the NPU performance.
• Different OS Power Modes: Test in various Windows power modes (e.g., Balanced, High Performance, Power Saver) to see if the issue persists across different power management settings.
• Power Cord (For Laptops): If you're using a laptop, try testing both with the power cord plugged and unplugged to assess any power-related impacts.
• NPU Driver in Device Manager: Try disabling/enabling the NPU driver in Device Manager to see if this alters the behavior of the integrated graphics and NPU.
• Reduce Parallel Processes: Test with a reduced number of processes running in parallel to minimize system resource contention and see if that helps resolve the issue.

Please let me know the results after testing these conditions, as it will assist us in further diagnosing the root cause of the issue. I am committed to resolving this matter and ensuring the best experience possible for your setup.

Thank you again for your patience and cooperation.

Can do but sorry, not now.

I may delay these tests for few weeks, cuz I need to get my own jobs done first.

Everyone needs to work and I have my own life as well u know
