•
The M710HD memory system supports up to 18 DIMMs. DIMMs must be installed in each
channel starting with the DIMM farthest from the processor. Population order will be
identified by the silkscreen designator and the System Information Label (SIL) located on the
chassis cover.
Memory Optimized or Sparing: {1, 2, 3}, {4, 5, 6}, {7, 8, 9}
o
Advanced ECC or Mirrored: {2, 3}, {5, 6}, {8, 9}
o

7.2 DIMMs Supported

If DIMMs of different speeds are mixed, all channels operate at the fastest common frequency.
•
UDIMMs are not supported.
•
The first DIMM slot in each channel is color‐coded with white ejection tabs for ease of
identification.
The M710HD's DIMM sockets are placed 380 mils (11.43 mm) or 400 mils apart (spacing is increased in
some areas to allow for more airflow); center‐to‐center in order to provide enough space for
sufficient airflow to cool stacked DIMMs. DIMMs must be installed in each channel starting with the
DIMM farthest from the processor (DIMM1). Population order is identified by silkscreen and a label.
The order is dependent on the memory configuration used. For detailed information, see the System
Memory section of the Dell PowerEdge Modular Systems Hardware Owner's Manual on
Support.Dell.com/Manuals.

7.3 DIMM Slots

Figure 3 illustrates the M710HD DIMM slots. For detailed information, see the System Memory section
of the Dell PowerEdge Modular Systems Hardware Owner's Manual on Support.Dell.com/Manuals.

7.4 Speed

The memory frequency is determined by a variety of inputs:
•
Speed of the DIMMs
•
Speed supported by the processor
•
Configuration of the DIMMs
Table 7 shows the memory populations and the maximum frequency achievable for that
configuration.
For quad-rank DIMMs mixed with single- or dual-rank DIMMs, the quad-rank DIMM needs to be in the
slot with the white ejection tabs (the first DIMM slot in each channel). There is no requirement for
the order of SR and DR DIMMs.
