Cisco UCS C240 M3 High-Density Rack Server (Large Form Factor Hard Disk Drive Model)

SUPPLEMENTAL MATERIAL

Recommended Memory Configuration

This section explains the recommended DIMM population order rules for the C240 M3 server.

■

All DIMMs must be DDR3 DIMMs.

■

Do not mix:

— DIMMs with different 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 37

when populating 1600- and

1866-MHz DIMMs for Intel Xeon E5-2600 v2 CPUs and

Table 38

when populating 1600-MHz DIMMs for Intel

Xeon E5-2600 CPUs.

NOTE: These tables list only some recommended and suggested configurations.
There are numerous other possible configurations supported by Cisco. Cisco supports
all mixing and population configurations of the Cisco DIMMs as long as the mixing
does not violate the few fundamental rules noted in this document.
