In a fully populated triple channel 24-module configuration, there was no difference in memory performance. The only difference we found was in a dual channel configuration where HP SmartMemory achieved slightly higher performance (2133 vs. 1866 MT/s). However, with the sheer number of memory-intensive server applications that are often being used, memory must be fully populated at the triple channel level in order to achieve maximum system density. For IT professionals, this comes down to the classic bandwidth versus capacity tradeoff, but as servers trend towards higher installed memory capacities, dual channel configurations are often only necessary for certain types of workloads.
No one configuration is the right configuration. It’s all about configuring memory to the demands of your workload. Based on the applications you’re running, you’ll want to configure your channels accordingly to achieve optimal performance.
