Optimizing the Performance of System Memory

Compute-intensive applications typically require as much system memory bandwidth as can be provided. For this reason, it is very important that system memory be correctly configured and installed. Microway reviews all systems to ensure proper performance (both during the sales and production/integration stages), however we provide this resource as a reference for those who would like to understand the options.

Improperly-configured memory can result in significant performance reductions. For example, a misconfiguration on the latest Intel Xeon CPUs with 6-channel memory controllers can result in a 65% reduction in memory throughput. This can result in an application running at half the anticipated speed. As you’re considering a new system deployment, please work with our experts to ensure success.

The correct configuration depends upon several factors, including the type of CPUs, the product generation, and the design of the system motherboard. To use the tables below, first select which type and generation of system CPUs will be in use. Then look to the rows which show the optimal memory capacities.

It should be noted that we consider a 64GB DIMM to be the largest available capacity in a single memory slot. Although 128GB and 256GB DIMMs are available, their extreme price and limited availability have made them impractical for most customer use cases.
