Maybe this MOBO is just choking on the combination of the type and quantity of
ram. Maybe the ram timing is just slightly under spec, and pulling one stick
puts the board into single channel mode. Have you tried pulling a stick from
the other channel also, so the board goes back into dual-channel mode, and
testing again? You could also see if you can change the memory timing slightly
with the 8 gigs of ram. See if the bios will let you turn off SPD mode and let
you set timings manually.

You hope everybody uses it, and
you notice quickly if they don't!!!!
