Sorry got busy and work. Any luck? None of lights stay on?
If not I would just double check and reseat everything, and for shits and giggles pull the cmos battery for 30s and put it back, if you haven’t already.
If nothing else works I would be thinking about RMAing the mobo.
Also remember that your parity has to be more or equal to the biggest drive in your array. If you buy a 10 but don’t have another 10 you must use the 10 as parity.
