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.
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 20 ).
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 20 ).
4. Remove the access panel (on page 23 ).
5. Open the DIMM slot latches.
