The M386B2G70DM0-YH9 is a server-grade DDR3 RDIMM explicitly designed for data-center platforms where data integrity and high memory density are critical. Its quad-rank x4 organization and registered signalling ensure stable operation under heavy loads, making it ideal for virtualization clusters and in-memory databases that demand robust ECC protection and consistent 1333MHz low-voltage performance.
1. Registered signal type ensures robust signal integrity across fully populated memory channels, safeguarding data reliability in large-scale server deployments.
2. ECC protection actively corrects single-bit memory errors, preventing silent data corruption that could compromise financial transactions or long-running analytics jobs.
3. Quad Rank x4 organization maximizes memory density per channel, enabling higher virtualization consolidation ratios without sacrificing performance predictability.
4. 16GB module capacity empowers dense server configurations to host more virtual machines and memory-hungry in-memory databases, directly reducing per-gigabyte infrastructure cost.
5. 1.35V low-voltage operation cuts data center power consumption and cooling demands, delivering tangible energy savings across hundreds of nodes running 24/7 workloads.
The M386B2G70DM0-YH9 is a server-grade DDR3 RDIMM, engineered for environments where uptime and data fidelity are non-negotiable. Its ECC technology actively detects and corrects single-bit memory errors, which is vital in a virtualization cluster: a flipped bit in a hypervisor's memory could silently corrupt multiple guest operating systems, leading to cascading failures. This module prevents such silent corruption, safeguarding every VM running on the host. The registered architecture buffers command signals, allowing a platform to support high-density Quad Rank configurations without signal degradation. In a memory-hungry in-memory database like Redis or SAP HANA, this means you can populate all 24 DIMM slots with 16GB modules and still enjoy rock‑solid stability, turning terabytes of system memory into a reliable cache for real-time analytics. The 1.35V low-voltage operation reduces thermal load and power draw across a full rack, lowering both cooling costs and carbon footprint. Combined with its Quad Rank x4 organization—which delivers deep interleaving and bandwidth needed for concurrent database queries—this RDIMM ensures that your dense compute nodes deliver consistent, error-free performance under 24/7 load.
General Virtualization
This 16GB DDR3L-1333 RDIMM with ECC is ideal for dense VM hosting. Deploy modules in multiples of 3 or 6 per populated memory channel to leverage triple-channel architecture and keep balanced interleaving. For a typical dual-socket server, start with six modules (96GB total) to comfortably consolidate 20–30 light-to-medium VMs while maintaining data integrity and low-latency access.
In-Memory Database
In-memory databases like Redis or SAP HANA demand large, reliable footprints, making registered ECC compulsory. Populate all memory channels identically with this quad-rank DIMM to maximize throughput and minimize rank contention. A 12-module configuration (192GB) per host suits moderate caching workloads; scale to 24 modules (384GB) for heavier OLAP datasets, ensuring 1.35V operation reduces thermal load in 24/7 deployments.
High-Performance Computing
HPC clusters benefit from this module’s low voltage and registered buffering, which stabilizes dense node configurations. Fill each memory channel with one DIMM per channel (1DPC) at 1333MHz to achieve the best speed bin while preserving quad-rank interleaving. Plan for at least 96–192GB per node using 6–12 identical modules to feed bandwidth-hungry MPI jobs, always matching ranks per channel to avoid performance cliffs from unbalanced access patterns.
Rigorously tested, this server memory is compatible with Dell PowerEdge R720, R620, HP ProLiant DL380p Gen8, and more.
Q: Can I mix this M386B2G70DM0-YH9 with other memory modules of different brands or speeds?
A: Mixing is not recommended. Different brands or speeds may cause instability. Registered ECC modules require matched ranks and timings for reliable server operation, especially with quad-rank DIMMs.
Q: Is this memory compatible with my system?
A: This RDIMM suits servers using Intel Xeon E5-2400/E5-2600 v1/v2 or AMD Opteron 6300 series platforms with C600-series chipsets. Verify your board supports quad-rank, 1.35V DDR3 Registered ECC memory.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical quad-rank DIMMs per channel, starting with the furthest slot from the CPU. For dual processor systems, balance memory across both to maintain uniform interleaving and bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No, server RDIMMs like this prioritize reliability over speed. It adheres strictly to JEDEC DDR3-1333 standards without XMP. Overclocking is not supported and would compromise ECC data integrity.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. Typical annualized failure rate for enterprise DDR3 RDIMM is under 0.5% under proper thermal conditions, ensuring very high reliability in 24/7 operations.
