This registered ECC memory module (DDR3-1333 16GB RDIMM, CL9, dual-rank x4) is purpose-engineered for legacy server platforms, delivering dependable data integrity for virtualization hosts and in-memory databases. Its registered architecture with ECC ensures stable signal integrity and single-bit error correction across dense memory configurations, making it ideal for sustained 24/7 enterprise operations.
1. ECC error correction detects and corrects single-bit memory faults in real time, safeguarding financial transactions and database integrity in always-on enterprise servers.
2. Registered signal buffering stabilizes high-density memory configurations, enabling reliable operation across fully populated DIMM slots in virtualized data centers.
3. 16GB module capacity provides ample headroom for dense server virtualization, allowing more simultaneous virtual machines without costly node expansion.
4. DDR3 technology at 1333MHz delivers consistent mainstream bandwidth that balances power and performance for mid‑range web servers and caching workloads.
5. Dual Rank x4 organization interleaves memory accesses across internal banks, maximizing channel utilization to prevent throughput bottlenecks during heavy multi‑tenant cloud processing.
The Samsung M393B2G70BH0-CH908 is a server-class Registered DIMM with ECC, purpose-built to solve the reliability and scalability challenges that keep data center managers awake at night. Its four defining characteristics translate directly into operational confidence. First, ECC error correction is non-negotiable for memory-intensive workloads. In a virtualized cluster hosting dozens of VMs, a single cosmic ray-induced bit flip in unprotected memory can silently corrupt a database transaction or crash a critical application. This module detects and corrects single-bit errors in real time, preserving data integrity across your entire stack. Second, the Registered signal buffer re-drives clock and command signals, which allows a server motherboard to populate all 24 DIMM slots without signal degradation. When you run an in-memory database like Redis or SAP HANA, populating multiple 16GB RDIMMs behind a buffer ensures stable, high-capacity memory pools that simply are not feasible with unbuffered modules. Third, the Dual Rank x4 organization engages parallel interleaving: the memory controller can issue commands to one rank while the other is busy, effectively hiding precharge latency. For virtualized environments, this means consistently low latency under the bursty I/O patterns of multiple tenants. Finally, the combination of 16GB density and DDR3-1333 CL9 speed hits an energy-efficient sweet spot, delivering the capacity per channel your hypervisor demands without excessive power draw. Every one of these features is engineered to turn hardware provisioning from a source of risk into a foundation of predictable performance.
The M393B2G70BH0 is a 16 GB DDR3-1333 Registered ECC DIMM (server memory). Use the following configuration guidelines for capacity planning.
General Virtualization — For dense VM hosting, install 8 to 12 identical modules (128–192 GB) equally across all memory channels in a dual‑socket system. This balanced layout ensures predictable performance under multi‑tenant loads and avoids remote memory access penalties.
In-Memory Database — Capacity takes precedence. Fill all available slots with these 16 GB RDIMMs. A server with 24 DIMM slots achieves 384 GB, suitable for large in‑memory datasets. Even if the memory speed drops to 1066 MHz at full population, the extra capacity compensates for latency‑sensitive database operations.
High-Performance Computing (HPC) — Minimize latency and maximize bandwidth. Configure one DIMM per channel (1DPC) to maintain 1333 MHz. In a dual‑socket server with four channels per CPU, eight modules (one per channel, identical dual‑rank) deliver the highest throughput for memory‑bound scientific simulations.
Always comply with the server platform’s population rules and use matching modules for all channels.
This server RAM is rigorously tested for compatibility with Dell PowerEdge R720, R620, HP DL380p Gen8, and similar systems.
Q: Can I mix this M393B2G70BH0-CH908 with other memory modules of different brands or speeds?
A: Mixing is not recommended for registered server memory. Different brands, speeds, or ranks can cause instability. For optimal reliability, populate all channels with identical Samsung 16GB DDR3-1333 RDIMMs.
Q: Is this memory compatible with my system?
A: This RDIMM is designed for servers using Intel Xeon E5-2400/2600 v1/v2 or AMD Opteron 6300/4300 series platforms. Verify your board requires 240-pin DDR3 registered ECC memory at 1.5V before ordering.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per channel starting with the farthest slot from the CPU. For dual-rank x4 modules, balance across memory channels to maximize interleaving. Consult your server's specific memory population guide.
Q: Does this module support overclocking or XMP profiles?
A: No. This is an enterprise-grade registered ECC DIMM operating at JEDEC-standard DDR3-1333 CL9. It does not support overclocking or XMP profiles, as stability and data integrity are prioritized over speed.
Q: What warranty and typical failure rate can I expect?
A: This module is covered by a one-year warranty. Samsung server memory boasts extremely low annualized failure rates, typically under 0.5%, ensuring dependable long-term operation in 24/7 enterprise environments.
