Memory Riser and DIMM Configuration

The memory riser configuration rules for the server are as follows:
The 2-processor server contains eight memory risers. The 1-processor server contains four
■
memory risers. Four memory risers are supported per CPU.
Each of the memory riser slots in the server must be filled with a memory riser.
■
There are only two possible memory configurations: Fully populated and half populated.
DIMM configuration rules for each memory riser are as follows:
For a fully populated configuration, DIMMs must be installed in all four DIMM connectors
■
on each memory riser.
For a half populated configuration (with 16GB or 32GB DIMMs), DIMMs must be installed
■
in the two black DIMM connectors (labeled J701_ZA and J701_ZB) on each memory riser.
All memory risers must contain the same rank, size, and type of DIMM.
