PCIe samsung 970 EVO not recognized while installing Win 10

@lebesgue  check your BIOS Setup by pressing F2 during startup and go to the System Information/Summary section, which should be at the top of the list in the left-hand column.  Check the information in the area on the right.  Do you see the 970 Evo listed there?  If so, then change the SATA Operation setting in your system from RAID to AHCI.  Despite the "SATA Operation" name, that setting affects NVMe SSDs.  You should then be able to install Windows 10 onto that SSD.  Technically you could keep RAID mode enabled and still install Windows 10 by supplying the Intel Rapid Storage driver during Windows Setup, but unless you plan to use a RAID setup, then there's no benefit to that mode when you're installing Windows onto an SSD.  An in fact if you want to use the Samsung NVMe driver later, you have to use AHCI mode anyway.

If you don't see the 970 Evo listed even in your BIOS, then try disconnecting and reseating the SSD in the slot if you haven't already.  Otherwise, it's possible that it's not compatible.  That shouldn't really happen, but there are a few confirmed cases of certain Dell models not working with the 970 Evo and Pro SSDs even though those same models work fine with the 960 Evo and Pro models.  Nobody that I've seen has found a fix, or even identified the underlying cause.

Did you manage to make it work? I'm wondering that to see if I buy that memory upgrade too.

Thanks.

That was an old post about installing a ssd -solid state drive-not ram. Start a new post with your computer model and OS to ask about upgrading your memory. Or just go to crucial.com to see what ram you can use.
