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 bank

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 27 when populating DIMMs.
