I also have the NPU showing as an issue in Device Manager, also code 43. I am on a similar configuration to yours, MSI Z890 Tomahawk motherboard, Intel Core Ultra 7 265K processor, and Corsair Dominator DD5 7200 MT/s CL36 (CMP48GX5M2X7200C36) - I wanted to get CUDIMM memory as it unlocks more of this platforms potential but this is very rare to come by here in South Africa.
I've searched around and found quite a lot of people reporting the same on other forums (ASUS, Reddit, Spiceworks). I ultimately resolved mine by changing my XMP profile from 2 to 1. I initially put memory back to standard and the NPU loaded normally, put it to XMP1 and it still loaded, when I put it to XMP2 the NPU showed as a problem again, but when I put it back to XMP1 it worked again.
I cannot say whether this alone resolved the problem as various other things were tried in all sorts of combinations, some of them I'll list below:
- uninstalling and deleting drivers from the driver repository store using RAPR
- trying the initial set of drivers installed
- disabling 200S boost
- changing performance profiles in the BIOS (only relevant and possible once 200S boost is disabled)
- changing PCIE power management settings)
I have restored most of the settings back now, I think the only thing I haven't is the PCIE power management settings. 200S Boost and XMP is enabled again, as otherwise I'm not getting the performance out of the hardware purchased. Technically speaking the XMP2 profile is an overclock profile for the memory modules I have, it pushes them up to 7400 MT/s from the 7200 MT/s it is rated/specced as being, so am happy at least to be getting the stated performance and not have to fall back to "standard" at 4800 MT/s.
Given the postings on other forums with motherboards from different vendors, different memory and different SKU processors I'm inclined to think there is either a hardware issue or limit or an issue in the drivers and firmware of the platform. I say this as I also note that I have the following warning in my Windows System logs for event ID 219, the hardware ID referenced in the message is for that of the NPU, but this warning is appearing even though the device has loaded normally and is working (confirmed by an OpenVINO framework benchmark run in Geekbench AI). It is possible that this message is due to one of the security features in Windows though (e.g. core isolation/memory integrity etc.) as I have seen this elsewhere before with completely different devices and drivers.
The driver \Driver\WUDFRd failed to load.
Device: PCI\VEN_8086&DEV_AD03&SUBSYS_7E321462&REV_01\3&11583659&0&20
Status: 0xC0000365
I've posted as much information that I think is relevant as I'm hoping you may find commonalities and either resolve your issue or the people at Intel are able to find the issue and note it (that it may give issues in certain configuration setups) or resolve it (if it is a driver/firmware issue).
