KVR21E15D8/16 Kingston 1x16GB DDR4 ECC RAM

High-Performance DDR4 ECC UDIMM Server Memory Expansion with the KVR21E15D8/16

The KVR21E15D8/16 is a 16GB DDR4 ECC Unbuffered UDIMM engineered for entry server and workstation platforms that require ECC UDIMM support and predictable JEDEC operation. In CPU-bound infrastructure nodes where core count and cache efficiency matter more than GPU acceleration, this module strengthens memory capacity while maintaining data integrity through ECC, helping reduce soft-error impact in always-on services.

Designed for DDR4-era Intel Xeon E3/E and comparable workstation platforms that expose ECC UDIMM channels, the KVR21E15D8/16 operates at DDR4-2133 (PC4-17000E) with CL15 timings at 1.2V to align with validated motherboard QVL baselines. As an unbuffered DIMM, it preserves low latency characteristics for small virtualization footprints, directory services, and file/print roles. While it does not change PCIe generation or storage topology, adding the KVR21E15D8/16 helps keep expansion resources effective by minimizing paging and supporting consistent I/O servicing under mixed workloads.

Why Choose the KVR21E15D8/16?

The KVR21E15D8/16 provides a practical density-to-stability improvement for compact servers where each DIMM slot is valuable and operational continuity is mandatory. Its ECC UDIMM architecture supports scalable growth from baseline deployments to larger memory footprints without shifting to registered DIMMs, making it suitable for standardized builds and incremental upgrades across branch or SMB infrastructure.

Kingston designs server memory with an emphasis on controlled component selection, standards-based JEDEC profiles, and compatibility discipline aligned to modern data centre operational requirements. The KVR21E15D8/16 follows this approach with a low-profile 288-pin form factor and RoHS compliance for enterprise procurement consistency.

Key Applications:

• File and print services
• Light virtualization on ECC UDIMM platforms
• Active Directory and DNS/DHCP
• Infrastructure monitoring and logging
