B450M Pro4 NVMe storage not recognized

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hey I just built a new mATX computer, finally got everything together and booted it to install Windows but it is not recognizing my NVMe storage.  I initially used a Samsung 970 EVO and then today picked up a cheaper Inland to compare.  Neither were recognized.

I installed them both in the M2 Ultra slot, not the M2_2.  My other HDDs and SSD are all recognized.  I even left the SATA3 open even though that is just for the M2_2.

Everything else seems to be working.  Is there something about the PCIe timing or something I need to initialize in BIOS?  Or is it perhaps just faulty and (ugh!) do I need to RMA my motherboard and have the fun time of putting it all together again?

Thanks for any input or help y'all can offer!
