7.3 DIMM Slots
The PowerEdge R210 II has 4 DIMM slots for memory, supporting up to 2 DIMMs per channel.
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
The memory speed of each channel depends on the memory configuration:
For single-rank memory modules
o One memory module per channel supports up to 1333 MHz
o Two memory modules per channel supports up to 1333 MHz
