7.4 Speed

The memory frequency is determined by a variety of inputs:
•
Speed of the DIMMs
•
Speed supported by the CPU
•
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.
