This Micron 16GB DDR3-1866 RDIMM (PC3-14900) with ECC and registered signaling is engineered for server platforms demanding data integrity in virtualized environments and memory-intensive databases. Its dual-rank x4 organization improves interleaving efficiency for sustained bandwidth, while the CL13 latency at 1.5V delivers a responsive 1866 MHz clock rate for legacy enterprise workloads.
1. ECC protection guards against single-bit memory errors, preserving data integrity for financial transactions and mission-critical database operations.
2. Registered signal type buffers the command and address lines, enabling large-capacity memory configurations while maintaining signal stability across multiple DIMMs per channel.
3. Dual Rank x4 organization interleaves memory access across internal banks, sustaining high throughput for virtualization platforms hosting numerous concurrent workloads.
4. The 1866MHz speed increases peak transfer rates, directly accelerating in-memory analytics and reducing response latency under heavy query loads.
5. Sixteen gigabyte capacity per module strikes a balance between density and cost, allowing a single server to allocate more memory per virtual machine without exhausting available slots.
The Micron MT36JSF2G72PZ-1G9E3H is a server-class Registered DIMM built for modern data centers, and its four defining characteristics directly solve the pain points of high-density enterprise computing. ECC technology silently intercepts single-bit errors caused by background radiation, which means your virtual machine fleet avoids random crashes and your financial records remain mathematically intact, even under 24/7 load. The registered buffer cleans and re-drives address signals, allowing you to fully populate all channels with 16GB dual-rank modules without electrical loading instability; this translates into confidently packing dozens of virtualized hosts per node without memory-related hypervisor faults. Its dual-rank x4 architecture uses interleaved access to squeeze out higher effective bandwidth, so an in-memory database like Redis or SAP HANA slices query latency during thousands of concurrent transactions. Finally, the 1866MHz speed with CL13 keeps the data pipeline fluid, accelerating analytics and live migration. This memory turns fragile, scalability-limited platforms into deterministic, always-on infrastructure where data integrity and rapid in-memory processing are non-negotiable.
General Virtualization
Balance capacity and bandwidth by installing one DIMM per memory channel. For a typical dual‑socket server with three channels per CPU, six of these 16 GB RDIMMs (96 GB total) efficiently support dozens of VMs. For heavier consolidation, scale to 12 identical modules (192 GB) while keeping ECC consistency across all slots.
In‑Memory Database
Maximize capacity and exploit dual‑rank x4 interleaving for lower latency. Fully populate a 12‑slot server to achieve 192 GB, which comfortably hosts mid‑sized Redis or Memcached datasets. Use only identical part‑number modules to maintain uniform timing and reliable error correction.
High‑Performance Computing (HPC)
Memory bandwidth is often the bottleneck. Populate two DIMMs per channel (2DPC) using these dual‑rank modules to reach 192 GB per node while preserving channel interleaving. Be aware that 2DPC at 1866 MHz may trigger a speed downgrade to 1600 MT/s; validate BIOS settings and voltage margin to sustain full frequency if supported.
Thoroughly tested server memory, compatible with Dell R720/R620, HPE DL380p Gen8, Lenovo RD640.
Q: Can I mix this MT36JSF2G72PZ-1G9E3H with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is not recommended. It can cause instability or failure to POST. For guaranteed performance, use identical Micron modules with the same speed, rank, and CAS latency.
Q: Is this memory compatible with my system?
A: This ECC Registered DDR3 module is designed for server platforms supporting 1866MT/s. It is compatible with Intel Xeon E5-2600 v2 series or AMD Opteron 6300 series using DDR3 RDIMM slots. Verify your server motherboard QVL.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate memory channels identically, starting with the farthest DIMM slot per channel (typically slot 1). For dual-rank x4 modules, fill all channels equally to maximize memory interleaving and bandwidth. Consult your server manual.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a server-grade Registered DIMM with ECC, operating at JEDEC standard DDR3-1866 CL13. It does not support XMP or overclocking; stability and data integrity are prioritized over adjustable clock speeds.
Q: What warranty and typical failure rate can I expect?
A: This Micron module comes with a 1-year warranty. Enterprise-class RDIMMs exhibit very low annualized failure rates (typically <0.5%) under specified environmental conditions, ensuring reliable 24/7 operation in data center environments.
