Dell R610 manual Speed

Dell™ PowerEdge™ R610 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 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.

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

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

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

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 memory speed of each channel depends on the memory configuration:

•For single- or dual-rank memory modules:

•One memory module per channel supports up to 1333MHz

•Two memory modules per channel supports up to 1066MHz

•Three memory modules per channel are limited to 800MHz regardless of the memory module speed.

•For quad-rank memory modules:

•One memory module per channel supports up to 1066Mhz

•Two 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).
