Solved - Ryzen/Win7 cannot see M.2 SSD

[D1398342003]

I'm running Windows 7 on an R7 1700 / Asus Crosshair Hero VI with the latest bios and drivers. My PCIE M.2 SSD shows up in the bios but Win7 doesn't see it. Device Manager reports no unidentified devices.

 

I'm not sure if I'm missing a driver or have the M.2 SSD configured incorrectly. Anyone have advice for how I can troubleshoot this?

what's the model of the m.2?

I think I remember hearing Ryzen doesn't support Windows 7/8? Somebody said that it only works with Win10, or is that just Intel Kaby Lake? Other than this, I have no idea what is causing the problem...

It's a Samsung PM951 MZVLV256HCHP.

I've been using Win7 on Ryzen for the last 3 months, and Asus offers drivers for Win7. I just haven't gotten the M.2 device to work. Other people have, and I can't seem to manage to replicate their fix.

You'll need Microsoft's NVMe hotfix. https://support.microsoft.com/en-us/help/2990941/update-to-add-native-driver-support-in-nvm-express-in-windows-7-and-wi

 

Either bake it in with software like NTLite, or install Windows on a SATA drive of some sort, install the hotfix, and clone the drive to the SSD

perfect. Just beware that Microsoft doesn't officially support Ryzen or Kaby Lake on anything earlier than Windows 10, and they like to break windows updates on those platforms occasionally.

Oh I know, but I've got no instability from Win7, so no problems there, and I just ran windows update today, after getting that unofficial open-source patch that prevents Microsoft from seeing the correct CPU.
