Recommended Memory Configuration
This section explains the recommended DIMM population order rules for the B200 M4 blades.
All DIMMs must be DDR4 DIMMs.
Do not mix:
DIMMs with different clock rates in a channel
RDIMMs and LRDIMMs
There are blue, black, and white DIMM slots. Populate blue slots first.
When DIMMs ranks are mixed in the same channel, always populate the highest rank DIMM in
the blue DIMM slot and lower rank DIMM(s) in the black and white DIMM slots.
Many memory configurations are possible. For best results, follow Table 24 when populating 2133-MHz
DIMMs for Intel Xeon E5-2600 v3 CPUs.
Table 24 Recommended Memory Configurations for Intel Xeon E5-2600 v3 CPUs (with 2133-MHz DIMMs)
