• T he DIMM sockets are placed 450 mils (11.43 mm) apart, center-to-center in order to provide

enough space for sufficient airflow to cool stacked DIMMs.

• T he PowerEdge R610 supports up to 12 DIMMs. DIMMs must be installed in each channel

starting with the DIMM slot farthest from the processor. Population order will be identified by

the silkscreen designator and the System Information Label (SIL) located on the chassis cover.

• M emory Optimized: {1, 2, 3}, {4, 5, 6}

• A dvanced ECC or Mirrored: {2, 3}, {5, 6}

• Q uad Rank or UDIMM: {1, 2, 3}, {4, 5, 6}

Memory Speed Limitations

The memory frequency is determined by a variety of inputs:

• S peed of the DIMMs

• S peed supported by the CPU

• C onfiguration of the DIMMs

The memory speed of each channel depends on the memory configuration:

• F or single- or dual-rank memory modules:

• O ne memory module per channel supports up to 1333MHz

• T wo memory modules per channel supports up to 1066MHz

• T hree memory modules per channel are limited to 800MHz regardless of the memory

module speed.

• F or quad-rank memory modules:

• O ne memory module per channel supports up to 1066Mhz

• T wo memory modules per channel are limited to 800MHz, regardless of memory

module speed

If memory modules with different speeds are installed, they will operate at the speed of the slowest

installed memory module(s).
