Engineer's Note

This Samsung M393B2G70EB0-YK0 is a registered DDR3-1600 ECC RDIMM engineered for server platforms, delivering critical data integrity and reliability for virtualization clusters and in-memory database workloads. Its dual-rank x4 configuration and 1.35V low-voltage operation enhance memory bandwidth and energy efficiency, while the registered signaling stabilizes high-capacity deployments in dense rack servers.

Technical Specs & Insights

1. ECC protection detects and corrects single-bit errors in real time, preventing silent data corruption that could crash critical enterprise workloads.
2. Registered signal buffering stabilizes command and address lines, enabling high-density memory configurations essential for large-scale virtualization hosts.
3. Dual Rank x4 interleaving maximizes memory bus utilization, reliably delivering the server-grade bandwidth required by data-intensive databases.
4. A low 1.35V operating voltage significantly reduces datacenter power consumption and thermal stress, improving total cost of ownership in always-on environments.
5. 16GB per module capacity allows denser memory population within limited server slots, directly increasing the number of virtual machines a single node can support.

Why These Specs Matter

As a server-grade Registered DIMM, the Samsung M393B2G70EB0-YK002 is engineered to address the critical demands of data center environments, where unplanned downtime and performance bottlenecks are simply unacceptable. Its ECC functionality is your frontline defense against single-bit memory errors, which cosmic rays or electrical noise can trigger and silently corrupt transactional data—for an in-memory database like SAP HANA or a financial trading system, this means the difference between audit-grade accuracy and a multimillion-dollar anomaly. The registered buffer enables stable population of all 24 slots in a dual-socket server without signal degradation, so your virtualization cluster hosting 100+ VMs never suffers from memory-related host crashes during peak load. Operating at just 1.35V, this DDR3-1600 module cuts the power draw per DIMM by nearly 20 percent versus standard 1.5V designs; when multiplied across a 512GB farm, that directly shrinks your cooling opex and raises rack density. Finally, the dual-rank x4 organization with CL11 timing balances low latency and high bandwidth, ensuring that a Redis or memcached caching layer can sustain millions of operations per second while keeping 16GB of hot data instantly available. For the infrastructure owner, this translates into hardened reliability, denser consolidation, and tangibly lower total cost of ownership.

Endurance & Reliability

The M393B2G70EB0-YK002 is a 16 GB DDR3L Registered ECC RDIMM built for servers.

General Virtualization
Populate memory channels evenly across both processors. Install six or eight of these DIMMs per CPU (96–128 GB) to combine balanced capacity with the bandwidth of a quad‑channel architecture. Use identical dual‑rank x4 modules to preserve reliable ECC operation and avoid rank‑configuration pitfalls.

In‑Memory Database
Capacity and data integrity are paramount. Fill every available DIMM slot with this 16 GB RDIMM, targeting 256 GB or more per server. The 1.35 V low‑voltage design cuts power draw while registered ECC keeps large memory arrays stable, supporting demanding real‑time transactional workloads.

High‑Performance Computing
HPC nodes need high sustained bandwidth. Configure two DIMMs per channel in a quad‑channel setup to deliver 128 GB per node at 1600 MHz. The dual‑rank construction provides a slight bandwidth edge over single‑rank parts, and the registered interface maintains signal integrity at density.

Verified Compatibility

Strictly tested, compatible with Dell PowerEdge R720, HP ProLiant DL380p Gen8, Lenovo ThinkServer RD530 and more.
