KVR21L15Q4/32 Kingston 1x32GB DDR4 LRDIMM ECC RAM

High-Density DDR4 ECC LRDIMM Server Memory Expansion with the KVR21L15Q4/32

The KVR21L15Q4/32 is a 32GB DDR4-2133 ECC Load-Reduced DIMM engineered for enterprise CPU platforms that support DDR4 ECC LRDIMM operation, enabling higher memory capacity per socket without compromising signal integrity. In virtualized clusters and database nodes, the quad-rank x4 architecture of KVR21L15Q4/32 helps reach target memory footprints with fewer populated slots than smaller RDIMMs, improving platform stability under heavy consolidation.

Designed for 288-pin DDR4 server channels, KVR21L15Q4/32 operates at 2133 MT/s with JEDEC CL15 timings at 1.2V, aligning with standards-based BIOS training across mainstream server boards. ECC protection on the 72-bit data path reduces soft-error exposure in 24x7 workloads, while the low-profile form factor supports dense rack servers and airflow-constrained chassis. For balanced systems, KVR21L15Q4/32 complements PCIe expansion and NVMe/SAS storage architectures by preventing memory bottlenecks that can limit I/O-driven services and in-memory processing.

Why Choose the KVR21L15Q4/32?

The KVR21L15Q4/32 is selected when capacity scaling and predictable reliability are architectural priorities: LRDIMM buffering supports higher DIMM population on compatible DDR4 platforms, and the quad-rank design enables efficient capacity growth per slot. This results in strong density-to-performance characteristics for consolidation, with ECC-focused operation supporting consistent service levels as fleets scale.

Kingston designs ValueRAM for standards compliance and controlled interoperability, emphasizing JEDEC alignment, traceable manufacturing, and compatibility validation for enterprise deployment cycles. This engineering approach supports modern data centre requirements for predictable behavior, maintainability, and long-term availability planning.

Key Applications:

• Server memory expansion for DDR4 ECC LRDIMM platforms
• Virtualization hosts and VDI density scaling
• Database and transactional application nodes
• Private cloud and hyperconverged infrastructure
• Enterprise application servers requiring 24x7 ECC reliability
