Lockstep Memory population guidelines
For Lockstep memory mode configurations, observe the following guidelines:
● Observe the general DIMM slot population guidelines.
● DIMM configuration on all channels of a processor must be identical.
● In multi-processor configurations, each processor must have a valid Lockstep Memory
configuration.
● In multi-processor configurations, each processor may have a different valid Lockstep Memory
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 L)
● RDIMM: Sequentially in alphabetical order (A through L)
● UDIMM: A through H, sequentially in alphabetical order. Do not populate DIMM slots I through L.
● HDIMM: All 12 DIMMs per processor must be populated.
After installing the DIMMs, use RBSU to configure Advanced ECC, online spare, or lockstep memory
support.
Installing a DIMM
The server supports up to 24 DIMMs. To install a DIMM:
1. Power down the server on page 18 .
2. Remove all power:
a.
Disconnect each power cord from the power source.
b. Disconnect each power cord from the server.
3. Extend the server from the rack on page 19 .
