You must load memory modules in valid configurations:
If loading only one DIMM, install it in slot 1. Otherwise, DIMMs must be loaded as matched pairs.
If loading two DIMMs, install them in slots 1 and 3.
If loading four DIMMs, install them in slots 1, 3, 5, and 7.
If loading six DIMMs, install them in slots 1 through 5, and 7.
If loading eight DIMMs, install them in all slots.
