Figure 12: This configuration has one interleave set because identical memory modules were
distributed evenly across the mirrored channels. The absence of all channels being populated makes
this configuration near balanced.
Figure 13: This configuration has one interleave set because identical memory modules were
distributed evenly across both mirrored channels and columns. The absence of all channels and
columns being populated makes this configuration near balanced.
7. Unbalanced Memory Topology Illustrations
Unbalanced configurations create more than one interleave set by unequally
distributing DIMMs across mirrored memory channel columns. These configurations
can reduce memory bandwidth by up to 33% from its maximum potential. Dell
EMC does not recommend populating memory in an unbalanced configuration.
