Engineer's Note

This 32GB DDR4-3200 RDIMM with ECC and a registered signal architecture ensures data integrity and signal stability, making it ideally suited for virtualization, in-memory databases, and mission-critical server workloads. Its dual-rank x8 configuration enhances memory interleaving efficiency, while CL22 latency delivers reliable, sustained throughput in dense multi-DIMM deployments.

Technical Specs & Insights

1. Registered signal buffering stabilizes high-density memory configurations, enabling seamless scaling for memory-intensive enterprise workloads.
2. ECC error correction safeguards transactional data integrity, preventing silent corruption in mission-critical database operations.
3. 32GB per module maximizes server memory footprints, allowing denser virtual machine consolidation without sacrificing performance.
4. DDR4-3200 data rate elevates memory bandwidth, accelerating real-time analytics and reducing latency in large in-memory datasets.
5. Dual Rank x8 organization leverages rank interleaving to boost sustained throughput, essential for virtualization hosts juggling multiple concurrent tenants.

Why These Specs Matter

In enterprise server environments, unplanned downtime or data corruption directly translates into revenue loss. The Samsung M393A4G43BB4-CWEGY is a DDR4-3200 Registered DIMM engineered to eliminate those risks, and its four core attributes make it indispensable for virtualization clusters and in-memory databases.

First, ECC technology silently corrects single-bit errors that cosmic rays or electrical noise can introduce. In a dense VMware farm running dozens of virtual machines, a flipped bit in a financial transaction or a customer record is catastrophic; ECC ensures data fidelity without administrative intervention. Second, the Registered signal buffer stabilizes high-capacity configurations by managing electrical loads on the memory bus. This lets you populate all channels with 32GB dual-rank modules without compromising signal integrity, maximizing the memory footprint your hypervisor needs for hundreds of VMs. Third, the dual-rank x8 organization interleaves accesses across internal banks, delivering visibly faster data throughput for latency-sensitive workloads like Redis or SAP HANA, where every microsecond counts. Finally, the 3200MT/s speed at a low 1.2V feeds modern multi-core CPUs a sustained 25.6GB/s of bandwidth per channel, keeping large datasets constantly in flight. This combination isn’t just a specification sheet—it’s the hardware guarantee your infrastructure demands for uncompromising reliability and performance.

Endurance & Reliability

Server Memory Capacity Planning Guide
The module is a 32GB DDR4-3200 Registered ECC RDIMM (dual-rank, CL22, 1.2V), purpose‑built for server platforms.

General Virtualization
Deploy six or eight identical 32GB RDIMMs across balanced memory channels to achieve 192–256GB total capacity. This configuration optimally populates dual‑socket systems for hosting 20–30 moderate VMs while maintaining memory bandwidth and hardware error correction. ECC protection is critical to prevent silent data corruption in multi‑tenant environments.

In‑Memory Database
Maximise capacity and populate all channels with identical modules, targeting 512GB–1TB using 16–32 DIMMs. Low CAS latency and dual‑rank design improve per‑channel throughput, accelerating large in‑memory datasets like Redis or SAP HANA. Always maintain balanced DIMM population per CPU to ensure predictable latency and bandwidth.

High‑Performance Computing
Leverage the 3200MT/s speed and registered buffering to combine eight modules per node for 256GB, ensuring two DIMMs per channel. Dual‑rank x8 RDIMMs deliver robust bandwidth for simulation and modeling workloads while ECC guards against compute‑silent errors. Scale linearly by replicating this kit across cluster nodes to sustain parallel file system and MPI job efficiency.

Verified Compatibility

This server RDIMM is rigorously tested and compatible with Dell PowerEdge R750, R650, HPE DL380 Gen10+, and Lenovo SR650 V2.
