Memory guidelines

There are a number of criteria that must be followed when installing memory modules in your compute node.

Populating memory modules for best system performance

The DIMM (memory) population sequences in this document show all memory population combinations that are supported by your compute node. Some of these combinations will perform better than others because they balance the distribution of memory across processors, memory controllers, and memory channels. Balanced memory configurations enable optimal interleaving across all populated memory channels of a processor to boost memory performance. To populate balanced memory configurations for the best memory performance, observe the following guidelines:

Where supported by specific memory population configurations, performance can be further enhanced by following these guidelines:
