Lockstep Memory population guidelines

For Lockstep memory mode configurations, observe the following guidelines:

• Observe the general DIMM slot population guidelines (on page 33).

• Always install DIMMs in channel 2 and 3 for each installed processor.

• Do not install DIMMs in channel 1 for any processor.

• DIMM configuration on channel 2 and channel 3 of a processor must be identical.

• In multi-processor configurations, each processor must have a valid Lockstep Memory mode

configuration.

• In multi-processor configurations, each processor may have a different valid Lockstep Memory mode

configuration.

Population order

For memory configurations with a single processor or multiple processors, populate the DIMM slots in the

following order:

• LRDIMM: Sequentially in alphabetical order (A through F)

• RDIMM: Sequentially in alphabetical order (A through F)

• UDIMM: A through C, sequentially in alphabetical order. Do not populate DIMM slots D through F.

After installing the DIMMs, use RBSU to configure Advanced ECC, online spare, or lockstep memory support.
