This Samsung M393B2G70BH0-CK04 16GB DDR3-1600 registered ECC module is purpose-built for server platforms tasked with virtualization, in-memory databases, and data-integrity-critical workloads. Its dual-rank x4 configuration and registered signal buffering deliver superior electrical stability in high-density memory deployments, while ECC error correction actively guards against data corruption during sustained operation.
1. With ECC protection, single-bit errors are detected and corrected in real time, drastically reducing the risk of silent data corruption in mission-critical databases and financial transactions.
2. Registered signal buffering stabilizes the command and address buses at higher densities, allowing servers to scale up to large memory footprints without compromising signal integrity under full load.
3. Dual Rank x4 organization interleaves multiple banks for higher sustained bandwidth, keeping virtualized workloads responsive even as consolidation ratios increase.
4. A 16 GB capacity per module raises the memory ceiling per server node, enabling more virtual machines and larger in-memory caches without adding physical hosts.
5. 1600 MHz data rate delivers the throughput necessary for memory-bound analytics and virtualization tasks, balancing latency and bandwidth in legacy and mid-range server deployments.
The M393B2G70BH0-CK04 is an RDIMM engineered for servers where data truth and continuous uptime are non-negotiable. As you consolidate dozens of virtual machines onto a single hypervisor, its registered architecture buffers command and address signals, allowing you to fully populate every memory channel without the signal degradation that would crash an unbuffered design—this directly maximizes VM density and protects your virtualized infrastructure investment. In an in-memory database like Redis or SAP HANA, the integrated ECC constantly corrects single-bit soft errors caused by background radiation, stopping a silent bit-flip from corrupting a financial transaction or altering a critical dataset; the module simply refuses to let your data drift. The dual-rank x4 organization interleaves memory access across two internal rank groups, which elevates sustained bandwidth and lowers access contention during heavy analytical queries, keeping latency predictable. At 1600 MHz with a 16 GB capacity, this 1.5 V module delivers the stable, error-free throughput your transactional systems and virtualization clusters demand day after day.
Server Memory Module Identified
This M393B2G70BH0-CK04 is a 16GB DDR3-1600 Registered ECC DIMM (RDIMM), designed for server platforms requiring data integrity and stable operation under sustained load.
General Virtualization
Populate servers with a balanced number of identical modules—typically six or eight per dual-socket system—to leverage multi-channel architecture and ECC error correction. Plan for 2–4 GB of RAM per virtual machine, so a host with 96–128 GB total comfortably supports dozens of mixed-load VMs without memory contention.
In-Memory Database
Maximize capacity by filling all available DIMM slots with these 16GB RDIMMs, reaching 256 GB or more on supported platforms. A low-latency CL11 rating and Registered buffering enable stable, high-throughput data access, reducing swap overhead for real-time analytics. Deploy in sets that match the CPU memory channels (e.g., four or eight modules) to preserve bandwidth.
High-Performance Computing (HPC)
Use a fully populated and symmetrical memory configuration—ideally one DIMM per channel across all sockets—to deliver uniform memory bandwidth for parallel workloads. Dual-rank x4 organization improves bank-level parallelism, benefiting large-scale simulations and model training. Combine 16 or more modules to achieve the hundreds of gigabytes often required, while ECC guards against silent data corruption during long compute runs.

Q: Can I mix this M393B2G70BH0-CK04 with other memory modules of different brands or speeds?
A: Mixing different brands or speeds is strongly discouraged in server environments. It can lead to signal integrity issues, ECC errors, and system instability. Always use identical modules for guaranteed compatibility and reliable 24/7 operation.
Q: Is this memory compatible with my Intel Xeon E5 or AMD Opteron server platform?
A: This DDR3-1600 Registered ECC RDIMM is compatible with Intel Xeon E5-2600 v1/v2 and AMD Opteron 6300/6200 series platforms. Ensure your server board supports 1.5V, 240-pin DDR3 RDIMM memory.
Q: What is the recommended DIMM population order for optimal performance on my server board?
A: Balance identical DIMMs across memory channels per CPU socket, filling the slot farthest from the CPU first. For dual-processor boards, populate memory symmetrically to maximize interleaving and overall memory bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. As a Registered ECC server DIMM, it strictly follows JEDEC specifications to ensure data integrity and system stability. Overclocking and XMP are not supported, as reliability takes priority over speed in server workloads.
Q: What warranty and typical failure rate can I expect for this server memory?
A: This module includes a 1-year warranty. Server-grade ECC RDIMMs typically exhibit an annualized failure rate (AFR) below 0.5% under specified conditions, offering excellent reliability for mission-critical enterprise applications.
