    NUC5i5RYH M.2 Detection Issues (Dead M.2 interface?)


      Hi All,


      I'm a first time NUC-owner, so I may be ignorant to certain aspects, however I've been putting together tech for many years. NUC-Pros: your advice is appreciated here!


      My configuration is:



      2x8 GB DDR3 1600 (no problems)

      M.2 SATA Drive*

      2.5" 2TB Samsung SATA Disk


      My problem:


      Since first unboxing, the NUC's bios will not detect anything in the M.2 slot. By this I mean: in the visual bios, in advanced, devices, SATA, the NUC lists under M.2 "[Not Installed]", when an M.2 stick is in place (also the sae in the PCIe menu, although they are SATA M.2).


      *I have tried the following M.2 sticks:


      ADATA Premier Pro SP900 M.2 256 GB SSD (22x80 M-key, SATA)

      Samsung 850 EVO, 250 GB SSD (22x80 M-key, SATA)


      Both should work, but after the ADATA was not detected, I thought perhaps I had acquired an incompatible M.2, so I looked through the boards here and noticed people had been successfully using the Samsung EVO SATA SSDs. I picked up an EVO, but I have the same result - neither are detected/listed in the visual bios.


      Other information:


      The 2.5" drive is detected correctly by the visual bios. Only M.2 is never detected (whether or not the 2.5" is connected).

      No errors are reported anywhere during power-up.


      What I have done:


      Read through every related forum post I could find on here.

      Powered on the NUC 'naked' (just memory), powered off, reinserted the M.2 and powered on again  - no joy.

      Reset the visual bios settings to default (F9) - no joy.

      Upgraded the bios to the latest version - no joy.


      What I'm considering:


      I can't think of anything else I can change/tinker-with to affect the configuration, so I'm wondering if the NUC is just not functioning correctly. Hence, I'm considering returning it for a replacement.


      I'd love to hear some comments and feedback first though!
