P21676-001 Kingston 1x64GB DDR4 ECC RAM

High-Performance DDR4 RDIMM Server Memory Module enabling capacity-driven scaling with the P21676-001

P21676-001 is a 64GB DDR4-3200 ECC Registered DIMM engineered for enterprise DDR4 CPU platforms where predictable memory behavior and signal integrity are required at scale. As an RDIMM, it supports registered buffering to improve electrical loading characteristics versus UDIMM designs, enabling stable population across multi-channel memory controllers in rack servers and dense virtualization nodes.

The P21676-001 module uses a dual-rank x4 organization with 72-bit data width to deliver ECC protection aligned with uptime-focused workloads. This architecture helps reduce the operational risk of memory faults in database, VDI, and VM consolidation scenarios, while maintaining JEDEC-compliant parameters for broad platform compatibility. With DDR4-3200 bandwidth and a server-grade profile (non-XMP/non-EXPO), P21676-001 is suited to configurations where consistent firmware training and deterministic boot behavior matter more than overclocking features. For systems with limited PCIe expansion headroom, increasing memory density per socket via P21676-001 can be a more efficient path to performance by minimizing paging, improving cache hit rates, and sustaining throughput under mixed read/write pressure.

Why Choose the P21676-001?

P21676-001 provides a practical density-to-performance balance for enterprises standardizing on 64GB RDIMMs to scale RAM capacity without increasing node count. It supports resilient operation through ECC and registered signaling, while offering a straightforward upgrade path for DDR4 server fleets that need predictable scalability across hypervisors and data tiers.

Kingston focuses on qualification-driven engineering for data center memory, emphasizing compatibility, controlled component selection, and consistent manufacturing to meet modern server platform requirements and lifecycle-managed deployments.
