Installing a memory module

The following notes describe the types of DIMMs that the compute node supports and other information that you must consider when you install DIMMs.

  1. You can install DIMMs for microprocessor 2 as soon as you install microprocessor 2; you do not have to wait until all of the DIMM slots for microprocessor 1 are filled.
  2. DIMM slots 9-16 are reserved for microprocessor 2; thus, DIMM slots 9-16 are enabled when microprocessor 2 is installed.
The following illustration shows the location of the DIMM connectors on the system board.

The following memory-channel configuration table shows the relationship between the processors, memory channels, and the DIMM connectors.
