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
