Engineer's Note

This 16GB DDR4-3200 Registered ECC RDIMM is architected for server platforms, targeting virtualization clusters, in-memory databases, and transactional workloads that require uncompromising data integrity. Its dual-rank x8 organization boosts interleaving efficiency for higher effective bandwidth, while the registered (buffered) signal path maintains stable command/address integrity across heavily populated memory channels with hardware error correction.

Technical Specs & Insights

1. A 16GB capacity per module allows dense memory footprints in 2U servers, preventing swapping and latency spikes when hosting dozens of virtualized workloads on a single node.
2. The 3200MT/s throughput translates to 25.6 GB/s of bandwidth per channel, accelerating large in-memory datasets and real-time analytics without data starvation.
3. ECC protection silently corrects single-bit errors from cosmic particle strikes or electrical noise, preserving transaction integrity in financial and database systems.
4. The registered clock driver buffers command and address lines, ensuring clean signal integrity across fully populated multi-DIMM channels for non-stop operation.
5. Dual rank x8 organization interleaves memory pages across internal banks, maximizing channel utilization and sustaining steady state performance under mixed enterprise workloads.

Why These Specs Matter

When evaluating memory for enterprise servers, the true measure is how it performs under relentless 24/7 loads and safeguards your data. The Samsung M393A2K43EB3-CWEBQ 16GB DDR4-3200 RDIMM is built to answer exactly those demands with four defining characteristics that directly solve real-world infrastructure pain points. Its ECC technology is your first line of defense against silent data corruption, automatically correcting single-bit errors that could otherwise crash an entire virtualized cluster or silently poison financial records in an in-memory database like SAP HANA. The registered buffer makes large-scale deployments stable: it reduces electrical load on the memory controller, allowing you to populate all channels to support dense VMware or Hyper-V hosts without signal degradation or unexpected reboots. This RDIMM’s dual-rank x8 organization then takes performance further by enabling interleaved access across ranks, boosting bandwidth and slashing latency for write-intensive database transactions. Powered at an energy-conscious 1.2V yet delivering swift 3200MT/s with CL22 timings, it gives your virtual machines responsive throughput while helping control operating costs in a packed data center. For your virtualized environments and high-performance databases, this translates directly to fewer service interruptions, faster query results, and the confidence that comes from memory engineered for unwavering reliability.

Endurance & Reliability

Server Memory – Capacity Planning Guide

This 16GB DDR4-3200 RDIMM (ECC, Registered, Dual Rank x8) targets server platforms requiring reliability and moderate capacity. Optimal configuration depends on workload demands.

General Virtualization
A balanced host running multiple VMs benefits from 6 to 8 such modules (96–128 GB) per CPU, populating one DIMM per channel for best bandwidth. Dual-rank RDIMMs at 3200 MT/s ensure consistent performance under mixed workloads.

In-Memory Database
For Redis or SAP HANA-like applications, maximize capacity per socket. Install 8 or 12 modules (128–192 GB) to keep entire datasets in RAM. Registered ECC memory guarantees data integrity, critical for transactional consistency.

HPC (High-Performance Computing)
HPC clusters favor memory bandwidth. Equip all 8 memory channels per server with one 16GB RDIMM to achieve 128 GB with maximum interleaving. For memory-bound simulations, double to 16 modules (256 GB) to avoid swapping and sustain throughput.
