Dell™ PowerEdge™ M610 Technical Guidebook

•The 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.

•The PowerEdge M610 memory system supports up to 12 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: {1, 2, 3}, {4, 5, 6}, {7, 8, 9}

•Advanced ECC or Mirrored: {2, 3}, {5, 6}, {8, 9}

•Quad Rank or UDIMM: {1, 2, 3}, {4, 5, 6}, {7, 8, 9}

Memory Speed Limitations

The memory frequency is determined by a variety of inputs:

•Speed of the DIMMs

•Speed supported by the CPU

•Configuration of the DIMMs

The table below shows the memory populations and the maximum frequency achievable for that configuration.

Note: For QR mixed with a SR/DR DIMM, the QR needs to be in the white DIMM connector. There is no requirement in the order of SR and DR DIMMs.

Not Supported

NOTE: For Quad-Rank DIMMs mixed with single- or dual-rank DIMMs, the QR 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
