Designed for server-class platforms, this 16GB DDR3-1866 RDIMM with ECC and registered signal buffering ensures robust data integrity and stability under heavy multi-threaded workloads such as virtualization and in-memory databases. Its dual-rank x4 configuration and low 1.35V operating voltage optimize memory bandwidth and power efficiency, while the CL13 latency delivers consistent performance in dense rack environments.
1. ECC memory actively detects and corrects multi-bit errors, preserving data integrity for mission‑critical database and financial transaction systems.
2. Registered signal buffering stabilizes command and address buses under heavy DIMM populations, enabling reliable operation in high‑density rack servers.
3. Dual Rank x4 organization keeps memory channels fully saturated, sustaining consistent virtual machine performance during aggressive consolidation.
4. A generous per‑module capacity footprint expands headroom for in‑memory caches and containerized workloads, minimizing costly storage I/O bottlenecks.
5. Elevated clock speed accelerates real‑time analytics and large‑dataset computations, directly shortening query response times in data‑intensive applications.
The Samsung M393B2G70BH0-YMA08 is a server-grade DDR3 RDIMM built for relentless reliability. In a virtualized cluster hosting multiple VMs, its Registered buffer stabilizes signal integrity across fully populated DIMM slots, preventing a single memory error from crashing the entire hypervisor and all resident workloads. Integrated ECC actively corrects single-bit errors induced by cosmic radiation or electrical noise, a capability that becomes vital for an in-memory database like Redis where a flipped bit silently corrupts financial transaction records. The dual-rank x4 design maximizes bandwidth utilization, effectively lowering latency under heavy OLTP patterns during peak trading hours when parallel access demands surge. Operating at a low 1.35V, this 16GB module substantially cuts power consumption across a dense data center, turning energy efficiency into direct OpEx savings for your always-on infrastructure. Ultimately, this memory serves as a critical foundation, defending data integrity and service uptime against invisible, unpredictable hardware faults.
Capacity Planning Guide for M393B2G70BH0 (16GB DDR3-1866 RDIMM)
This module’s ECC, Registered, and 240-pin design identifies it as server memory. Used in dual-socket or high-density platforms, it suits the following workloads.
General Virtualization
Populate all memory channels identically—install eight 16GB modules (128GB) across two channels per processor for balanced capacity and throughput. Scale to sixteen modules (256GB) on dual-socket systems to host numerous VMs, support live migration, and absorb peak demands without swapping.
In-Memory Database
Maximize capacity by filling every available slot; aim for 16 identical 16GB RDIMMs (256GB) or higher to hold entire datasets in RAM. The specified dual-rank x4 construction provides reliable high density, minimizing access latency and ensuring real-time transaction performance under heavy loads.
High-Performance Computing
Configure one DIMM per channel at minimum, but install two matched 16GB modules per channel (e.g., 8×16GB = 128GB for a quad-channel node) to enable rank interleaving and peak bandwidth. Keep all channels identical to sustain stable, synchronized memory throughput during parallel simulations and large‑scale data processing.
Rigorously tested server memory, compatible with Dell R720, HP DL380p Gen8, Lenovo x3650 M4, and more.
Q: Can I mix this M393B2G70BH0-YMA08 with other memory modules of different brands or speeds?
A: Mixing RDIMMs with different brands, speeds, or ranks is not advised in servers. It may cause POST failures or intermittent ECC errors. To guarantee signal integrity and reliability, always install identical Samsung modules with the same 1866MHz/CL13 specification.
Q: Is this memory compatible with my system?
A: This 16GB DDR3-1866 Registered ECC RDIMM is designed for dual-processor servers based on Intel Xeon E5-2600 v2 or AMD Opteron 6300 platforms. Verify that your motherboard supports 1.35V low-voltage registered DIMMs and features 240-pin DDR3 slots.
Q: What is the recommended DIMM population order for optimal performance?
A: For optimal performance, balance the memory across both CPU sockets. Populate one DIMM per channel symmetrically, then fill remaining slots. Always follow your server motherboard’s specific population sequence to ensure all memory channels and ECC functions operate correctly.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant enterprise server module. It strictly operates at DDR3-1866 with fixed CL13 timings and does not support overclocking or XMP profiles. It is engineered for stable, error-free 24/7 operation in data center environments.
Q: What warranty and typical failure rate can I expect?
A: This Samsung module includes a one-year warranty. Enterprise-grade RDIMMs demonstrate exceptionally low failure rates, typically an AFR below 0.2%, thanks to rigorous component screening and extensive application testing for continuous mission-critical workloads.
