Recommended Memory Configuration
This section explains the recommended DIMM population order rules for the C220 M3 server.
■ All DIMMs must be DDR3 DIMMs.
■ Do not mix:
— DIMMs with different sizes or clock rates in a channel
— RDIMMs and LRDIMMs
— ECC and non-ECC DIMMs
■ There are blue and black DIMM slots. Populate blue slots first.
■ When single- and dual-rank DIMMs are populated for 2DPC, always populate the dual-rank
DIMM in the blue DIMM slot and the single-rank DIMM in the black DIMM slot.
Many memory configurations are possible. For best results, follow Table 34 when populating DIMMs.
