Energy Efficiency Features

Operating at 1.2V, the DDR4 standard provides significant power savings compared to DDR3's 1.5V operation. Additional power management features include temperature-controlled auto-refresh, which adjusts refresh rates based on die temperature, and partial array self-refresh capabilities that enable power savings during idle periods. These features contribute to reduced total cost of ownership through lower power consumption and cooling requirements in large-scale deployments.

Workload-Specific Performance

Virtualization and Cloud Workloads

The 64GB capacity per module enables higher virtual machine density by providing substantial memory resources in a single DIMM slot. This is particularly valuable in VxRail environments where memory availability often determines the number of virtual machines that can be hosted per node. The 3200MHz speed ensures responsive performance during memory contention scenarios when multiple virtual machines compete for memory resources, while the ECC protection maintains data integrity across diverse workload types.
