The M386B2K70DM0-YK00 is a 16GB DDR3L-1600 Registered ECC RDIMM engineered for server platforms, making it ideal for virtualization, in-memory databases, and data-critical enterprise workloads. Its Quad Rank x4 configuration maximizes capacity density per channel, while the registered signal topology and ECC deliver robust signal integrity and bit-level error correction under heavy multi-DIMM loading.
1. Generous per-module capacity elevates virtualization density, allowing a single server to host substantially more active virtual machines and larger in-memory datasets without expanding hardware footprint.
2. High data rate ensures ample throughput to fully utilize multi-core server processors, keeping latency low under intense concurrent transactional and database workloads.
3. End-to-end error correction protects data integrity against silent bit-flips, delivering the mission-critical reliability demanded by financial services and enterprise analytics.
4. Registering buffers stabilize the memory bus under heavy loads, enabling dependable large-capacity configurations that maintain uptime for always-on enterprise infrastructure.
5. Quad-rank organization saturates memory channels with deeper bank parallelism, preventing bandwidth starvation and maintaining consistent performance in heavily consolidated virtualized environments.
The M386B2K70DM0-YK00 is a DDR3-1600 Registered DIMM purpose-built for enterprise servers, where reliability and density are not optional. Its ECC protection silently detects and corrects single-bit errors in real time, a non-negotiable safeguard for long-running virtualization clusters—without it, a cosmic-ray-induced bit flip could silently corrupt guest machines and bring critical workloads to an unpredictable crash. The Registered buffer reinforces signal integrity when every channel is populated, allowing you to deploy high-capacity Quad Rank configurations without the electrical loading that would destabilize unbuffered modules in a fully loaded 24-DIMM server, so your VM density can scale with confidence. That Quad Rank x4 organization further accelerates in-memory databases like Redis or SAP HANA by maximizing bank interleaving, enabling parallel accesses to dramatically reduce latency under heavy transactional queries. Operating at just 1.35V, the module slashes power consumption by roughly twenty-five percent versus standard 1.5V DDR3, directly shrinking cooling overhead in dense data centers and preventing thermal throttling that degrades sustained performance. These features converge to deliver uncompromised data integrity, massive consolidation ratios, and responsive analytics—turning raw infrastructure into a continuously available business engine.
General Virtualization
For general virtualization hosts, this 16 GB DDR3L-1600 ECC Registered DIMM strikes an excellent balance between density and power efficiency. Deploy six to eight modules per dual‑socket server to reach 96–128 GB, which supports 20–30 typical virtual machines comfortably. Always install in matched sets of three or four per CPU to maintain triple‑channel or quad‑channel operation and avoid performance bottlenecks.
In‑Memory Database
In‑memory databases demand both capacity and data integrity, making this ECC RDIMM a solid building block. Populate all available DIMM slots—often 12 or 16 per server—with identical 16 GB modules to achieve 192–256 GB, enabling large datasets to reside entirely in RAM. The 1.35 V low‑voltage design also reduces thermal load in dense configurations, critical for sustained database uptime.
High‑Performance Computing (HPC)
HPC clusters benefit from the registered, quad‑rank architecture that allows high capacity per channel while maintaining signal integrity. Use balanced configurations of 8 or 16 modules per node to supply 128–256 GB, keeping memory channels fully populated for maximum bandwidth. The ECC protection and low CAS latency of CL11 help ensure result accuracy during long-running, compute‑intensive simulations.
Rigorously tested, compatible with Dell PowerEdge R720, HP ProLiant DL380p Gen8, IBM System x3650 M4, and more.
Q: Can I mix this M386B2K70DM0-YK00 with other memory modules of different brands or speeds?
A: Mixing with different brands or speeds is strongly discouraged. Variations can cause instability; all DIMMs should be identical in type, rank, speed, and ECC to ensure server reliability.
Q: Is this memory compatible with my Intel Xeon E5-2600 v2 server?
A: The M386B2K70DM0-YK00 is compatible with platforms supporting DDR3L-1600 Registered ECC, such as Intel Xeon E5-2600 v2 or AMD Opteron 6300 series. Always verify against your server's memory QVL.
Q: What is the recommended DIMM population order for optimal performance?
A: For Quad Rank RDIMMs, populate identical modules starting from the slot farthest from the CPU per channel. Follow your server manual; balanced loading across channels prevents clock speed downgrades.
Q: Does this module support overclocking or XMP profiles?
A: No. This server memory adheres to JEDEC DDR3-1600 CL11 standards. Overclocking or XMP is not supported, as it would compromise ECC protection and system stability.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. Enterprise-class RDIMMs exhibit very low annualized failure rates, typically under 0.2%, delivering high reliability for 24/7 operation.
