* For dual-channel configuration (3), you may:
• install identical DIMMs in all four sockets
• install identical DIMM pair in DIMM_A1 and DIMM_B1 (blue sockets)
and identical DIMM pair in DIMM_A2 and DIMM_B2 (black sockets)
• install same size DIMMs in DIMM_A1 and DIMM_B1 (blue sockets) and
another same size pair in DIMM_A2 and DIMM_B2 (black sockets)
