This 32GB DDR3-1600 RDIMM is purpose-built for legacy server platforms running memory-intensive virtualization or in-memory database workloads, where its ECC and registered signal type ensure end-to-end data integrity under sustained high-load conditions. The quad-rank x4 organization maximizes capacity per channel while the low 1.35V operating voltage improves power efficiency in dense rack deployments, making it a reliable choice for scaling older dual-socket systems.
1. ECC error correction actively detects and fixes single-bit memory errors, preserving data accuracy for financial transactions or database operations where even one flipped bit is unacceptable.
2. Registered signal buffering stabilizes command and address lines across heavily loaded memory channels, allowing dense server nodes to run stably without signal degradation.
3. Quad Rank x4 organization packs more logical banks per DIMM, delivering the memory footprint needed to host large virtualized environments without sacrificing channel stability.
4. A generous 32-gigabyte capacity per module enables in-memory caching of massive datasets, accelerating real-time analytics and reducing storage I/O bottlenecks.
5. Low-voltage 1.35-volt operation trims overall server power draw and thermal output, directly lowering cooling costs in scale-out data center deployments.
The Samsung M386B4G70DM0-YK04 is a registered DDR3 server memory module engineered for mission-critical enterprise workloads, where undetected memory errors are simply unacceptable. In a dense virtualization cluster running dozens of virtual machines, the integrated ECC continuously detects and corrects single-bit errors, preventing silent data corruption that could crash hypervisors or corrupt critical databases. Its registered architecture buffers command and address signals, so adding multiple high-capacity DIMMs per server does not degrade signal integrity—this means you can confidently populate all channels to maximize memory density without sacrificing stability. At 32GB per module built on quad-rank x4 construction, this RDIMM is ideal for memory-hungry in-memory databases like SAP HANA or Redis clusters: it delivers the deep capacity needed to keep entire datasets in volatile memory, slashing latency and accelerating real-time analytics. Operating at 1.35V, it reduces memory subsystem power draw and waste heat, which becomes immensely important when you scale across racks of servers—lower thermal stress directly translates into higher platform reliability and longer component lifespan. Together, these four characteristics turn raw specifications into tangible operational gains: fewer downtime events, predictable performance under heavy multi-tenant loads, and a lower total cost of ownership for your data center.
General Virtualization
For a quad-rank 32GB RDIMM, populate two modules per channel for a balanced 64GB per host to support moderate VM density. Avoid fully populating all channels with quad-rank DIMMs, as this may force the memory controller to downclock to 1066MHz, hurting latency-sensitive VMs. Stick to a 2 DIMMs-per-channel configuration on dual-socket servers for an optimal blend of capacity and speed.
In-Memory Database
Deploy six to eight of these 32GB ECC Registered DIMMs per socket to reach 192–256GB, enabling large in-memory datasets like Redis or SAP HANA. The CL11 latency and 1600MHz speed are sufficient, but prioritize populating one DIMM per channel first to maintain full bandwidth—critical for high-throughput database operations.
High-Performance Computing
Use one DIMM per channel to avoid rank proliferation penalties, capping at four modules per socket for a 128GB footprint that keeps 1600MHz frequency intact. For memory-bound HPC workloads, this layout maximizes bandwidth while ECC guards against silent data corruption during long simulation runs. If greater capacity is required, consider 2Rx4 modules instead to sustain clock speeds.
Rigorously tested server RAM, compatible with Dell PowerEdge R720, HP DL380p Gen8, Lenovo RD430 and more.
Q: Can I mix this M386B4G70DM0-YK04 with other memory modules of different brands or speeds?
A: Mixing brands or speeds is not recommended, especially in server environments. Registered ECC DIMMs require matched specifications to ensure signal integrity and avoid stability issues in mission-critical workloads.
Q: Is this memory compatible with my system?
A: This is a DDR3-1600 ECC Registered DIMM designed for specific server platforms (e.g., Intel Xeon E5-2600 v2 series with C602 chipset). Verify your motherboard or server's qualified vendor list for RDIMM support.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server board's manual. With this quad-rank DIMM, typically populate the first slot of each memory channel, using identical DIMMs. Balancing ranks per channel maximizes throughput in multi-channel architectures.
Q: Does this module support overclocking or XMP profiles?
A: No, server-grade Registered ECC memory operates only at standard JEDEC timings (CL11). Overclocking and XMP profiles are not supported, as reliable data integrity takes priority over overclocking in server environments.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. The failure rate is extremely low thanks to rigorous factory testing and ECC technology, which detects and corrects single-bit memory errors for enhanced reliability.
