Designed for legacy server infrastructures, this 32GB DDR3-1866 Registered ECC module leverages a Quad Rank x4 organization to deliver exceptional memory density per channel, making it ideal for virtualization hosts and in-memory databases that demand large, reliable footprints. Its 13-cycle CAS latency and registered signal buffering ensure stable operation under heavy multi-DIMM configurations, preserving data integrity across enterprise workloads.
1. ECC detection automatically corrects single-bit errors and flags multi-bit faults, preserving financial transaction integrity and preventing silent data corruption in mission-critical databases.
2. Registered signal buffering stabilizes command and address signals across heavily loaded motherboards, enabling large memory populations without compromising signal integrity in virtualized clusters.
3. RDIMM form factor ensures compatibility with enterprise server platforms, allowing IT administrators to scale memory capacity predictably for growing SaaS workloads.
4. 32-gigabyte capacity increases VM density per physical host, directly lowering licensing costs and rack space requirements in consolidated private cloud environments.
5. Quad Rank x4 construction packs more DRAM devices per channel, maximizing throughput for in-memory analytics and large-scale content caching under sustained load.
Designed for mission-critical server environments, the Samsung M386B4G70DM0-CMA 32GB DDR3-1866 RDIMM turns raw specifications into tangible data center reliability. Its ECC technology silently detects and corrects single-bit memory errors, preventing silent data corruption that could crash a virtualized cluster or poison a financial transaction—this means your hypervisor maintains consistent VM integrity 24/7. The registered buffer acts as an intelligent signal amplifier, stabilizing commands across densely populated channels, so when you populate all 24 DIMM slots in a virtualization host, you avoid the signal degradation that causes unpredictable reboots. The quad-rank x4 organization leverages rank interleaving, overlapping activation cycles to sustain higher effective bandwidth under concurrent loads, directly translating to faster response times when hundreds of users hammer an in-memory database like Redis or SAP HANA. Finally, the CL13 latency at 1866 MT/s balances burst throughput with prompt data access, reducing stalled CPU cycles during complex query execution. For virtualized clusters and database nodes, this module isn’t just memory—it’s the insurance that uptime and performance won’t silently degrade under pressure.
This is a 32GB DDR3-1866 ECC Registered RDIMM (quad rank, 1.5V), designed for server platforms. Use the following capacity planning guidance for typical enterprise workloads.
General Virtualization
Equip dual-socket servers with one 32GB DIMM per memory channel – typically 8 modules for a 256GB total when using 8 channels per CPU. This avoids the performance penalty of mixing quad‑rank DIMMs on a channel, maintains the 1866 MT/s speed, and provides ample memory for dozens of VMs. For light consolidation, 4 modules (128GB) is a cost‑effective starting point.
In-Memory Database
Maximize capacity with 16 or more modules per host, populating two DIMMs per channel where supported, even if speed drops to 1600 MT/s. A 512GB to 1TB config with 16–32 of these registered 32GB sticks allows entire datasets to reside in RAM, critical for Redis or SAP HANA. Ensure the system’s memory controller can handle quad‑rank loads on each channel.
High-Performance Computing
Deploy one DIMM per channel to sustain the full DDR3-1866 clock speed, minimizing latency for bandwidth‑sensitive HPC applications. For a typical dual‑socket node with eight channels, an 8‑module setup yields 256GB at peak throughput. If capacity demands grow, add a second quad‑rank DIMM per channel only after validating the resulting speed reduction is acceptable for the workload.

Q: Can I mix this M386B4G70DM0-CMA with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is not recommended. The system defaults to the slowest module’s timings and may face stability issues due to signal integrity variations in Quad Rank configurations.
Q: Is this memory compatible with my server? It's using an Intel Xeon E5-2600 v2 processor.
A: Yes, this DDR3-1866 Registered ECC module is compatible with platforms like Intel Xeon E5-2600 v2 series. Please verify your motherboard supports Quad Rank x4 32GB RDIMMs and a 1.5V operating voltage.
Q: What is the recommended DIMM population order for optimal performance?
A: For optimal performance, populate identical Quad Rank RDIMMs in sets of three per memory channel. Follow your server's specific slot numbering—typically slots 1, 4, 7 first—to balance load and maximize bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-grade Registered ECC memory running at standard JEDEC DDR3-1866 specifications, this module does not support overclocking or XMP profiles to ensure data integrity and platform stability.
Q: What warranty and typical failure rate can I expect with this memory?
A: This module includes a one-year warranty. Enterprise RDIMMs like the M386B4G70DM0 typically exhibit AFR below 0.5%, reflecting the high reliability of rigorously tested, ECC-protected server memory components.
