Just to elaborate a little on that, even a different BIOS version between the 2 boards could cause OS inconsistencies. It is one thing to update the BIOS and another to swap the board to one with a different BIOS, there are numerous hidden values in any UEFI that are particular to a given board. Windows 10 in particular seems to be sensitive to some of these. When you set up windows on a system there are changes made to the UEFI by the installation process (the hidden values I eluded to above) if the OS was not installed on this board there may be entries on the new one that differ from the old.
If you have a spare drive knocking about you could try installing Windows 10 on that with the raid array disconnected and see if that resolves the issue (after hooking up the RAID array again). It may require another raid array to properly set the values though. Worth a shot considering how quick an OS install is these days.
