therefore, Single Rank DIMMs cannot be used. DIMMs in a pair must be identical in type, size, and rank.

Memory Optimization

The memory subsystem can be optimized for various factors, including performance, capacity, or power

consumption. Refer to the following guidelines when you are selecting memory options:

Guidelines for maximum memory performance:

Use all available memory channels (four per processor, eight total per system).

Use identical DIMM populations in size and speed across channels.

Populate both processors with equal amounts of memory.

Populate the same number of ranks per channel.

Have at least two ranks available on each channel.

Guidelines for lowest memory energy consumption

Use fewer, higher capacity DIMMs. For example, a configuration of 8x 16 GB DIMMs often has

lower power requirements than a configuration of 16x 8 GB DIMMs, despite the same capacity.

Populating more DIMMs per channel—but using fewer channels (the opposite of the preceding

bullet)—further reduces overall system energy use, but at the cost of significant performance

reduction.
