Cisco UCS C240 M4 High-Density Rack Server (Small Form Factor Disk Drive Model)

SUPPLEMENTAL MATERIAL

Recommended Memory Configuration

This section explains the recommended DIMM population order rules for the C220 M4 server.

■ All DIMMs must be DDR4 DIMMs.

■ Do not mix:

— DIMMs with different clock rates in a channel

— RDIMMs and LRDIMMs

— ECC and non-ECC DIMMs

■ There are blue, black, and white DIMM slots. Populate blue slots first.

■ When DIMMs ranks are mixed in the same channel, always populate the highest rank DIMM in

the blue DIMM slot and lower rank DIMM(s) in the black and white DIMM slots.

Many memory configurations are possible. For best results, follow Table 38 when populating 2133-MHz

DIMMs for Intel Xeon E5-2600 v3 CPUs.
