Optane DCPMM does not have storage driver in Windows 2025?

Hi, I just my 2 DCPMM 100 series 512GB. I configured them in 51/49 mix mode in windows 2025. The memory side is fine, I can see INVDIMM driver are loaded and system is showing 512GB available. However, the storage side, it’s missing driver for it. I can’t use it at all right now. The New-PmemDisk command does not work either.
Does anyone know where to find the driver?

that’s not great

Is the disk populating under storage spaces or device manager?

here’s a reference from Server 2019 days:

I haven’t checked my NVDIMMs on Server 2025 yet, will try to get around to it before week’s end.
