6. Near Balanced Configurations
Near balanced configurations satisfy NPS 1 or 2 conditions by populating either four or
twelve identical DIMMs per CPU. These configurations are not optimized because the
channels are partially populated, which creates disjointed memory regions that reduce
performance (making it near balanced). Performance for near balanced configurations
will undergo degradation when compared to balanced configurations. Although the
below configurations are adequate for implementation, they are not highly
recommended. *Note that CPUs 7282, 7252, 7232P and 7272 were designed to reduce the
performance impact of populating four DIMM channels.
