Optimizing Memory Performance

Revision: 1.4

Issue Date: 4/21/2020

Abstract

Properly configuring a server with balanced memory is critical to ensure memory

bandwidth is maximized and latency is minimized. When server memory is configured

incorrectly, unwanted variables are introduced into the memory controllers’ algorithm,

which inadvertently slows down overall system performance. To mitigate this risk of

reducing or even bottlenecking system performance, it is important to understand what

constitutes balanced, near balanced and unbalanced memory configurations.

Dell EMC has published this brief to educate PowerEdge customers on what balanced

memory means, why it is important and how to properly populate memory to 2
