Rank sparing mode
In rank sparing mode, one rank of a DIMM works as the spare rank for the other ranks on the same channel.
The spare rank is not available as system memory.
Notes:
• All DIMMs to be installed must be the same type with the same capacity, frequency, voltage, and ranks.
• If the rank of installed DIMMs is one rank, follow the installation rules listed in the following tables. If the
rank of installed DIMMs is more than one rank, follow the installation rules of independent mode.
The following table shows the DIMM population sequence for rank sparing mode when only one processor
(CPU1) is installed.
