This DDR3-1866 RDIMM with ECC and registered signaling is purpose-built for server platforms handling virtualization and memory-intensive databases where data integrity is non-negotiable. Its dual-rank x4 organization and CL13 latency ensure stable, high-throughput operation in multi-DIMM configurations, while hardware error correction safeguards against silent data corruption in 24/7 enterprise workloads.
1. 16 GB capacity per module lets a single server host more virtual machines and containers, directly increasing consolidation ratios without sacrificing memory headroom.
2. ECC support silently detects and corrects single-bit errors in real time, protecting long-running database transactions and financial calculations from silent data corruption.
3. Registered signal buffering decouples the memory controller from the electrical load of multiple DIMMs, preserving command integrity in densely populated systems that require terabytes of reliable RAM.
4. Dual Rank x4 organization interleaves accesses across internal banks to sustain channel saturation, providing predictable bandwidth for analytics and virtualized workloads under heavy consolidation.
5. 1866 MHz speed raises the peak transfer rate to PC3-14900, shrinking the response time for in-memory caches and data-intensive decision-support queries on multi-core servers.
The Micron MT36JSF2G72PZ-1G9E1KF is a 16GB DDR3-1866 registered DIMM engineered for server environments where uptime and data integrity directly impact revenue. Its ECC technology actively detects and corrects single-bit errors in real time, preventing silent data corruption that could crash a virtualization host running dozens of VMs or taint transaction ledgers in an in-memory database like SAP HANA. The registered buffer re-drives address and command signals, so you can fully populate all six or eight memory channels without signal degradation—a decisive factor when scaling a VMware cluster to maximize VM density without unexpected reboots. Dual-rank construction with x4 DRAM organizations interleaves internal banks to sustain higher throughput under concurrent access patterns; in a heavily fragmented Redis caching layer or during complex online analytical processing, that translates into lower tail latency and smoother query performance. With a full 16GB capacity per module at 1866MHz, IT teams can extend older-generation server life cycles, consolidate mixed workloads onto fewer physical nodes, and retain the bulletproof reliability that regulatory and business-critical applications demand.
Server Memory – ECC Registered DDR3-1866 16GB RDIMM
This module is designed for server platforms. Below are capacity recommendations for typical workloads.
General Virtualization
In virtualized environments, memory capacity and reliability are critical. Install these 16GB DDR3-1866 RDIMMs evenly across all available memory channels—one DIMM per channel for optimal speed or two per channel for extra capacity. A common dual-socket build uses eight modules (128GB) for dozens of VMs, leaving room for upgrades; always use identical DIMMs.
In-Memory Database
In-memory databases require maximum capacity and low latency. Fill all DIMM slots with these dual-rank x4 RDIMMs to reach platform limits, often 384GB or more. Populating multiple DIMMs per channel may drop speed to 1600/1333MHz, but the capacity gain outweighs the bandwidth reduction. Balance modules across channels and NUMA nodes. This fits large Redis or HANA deployments.
High-Performance Computing (HPC)
HPC workloads demand peak bandwidth. Install one DIMM per channel to sustain the full 1866MT/s speed. For a dual-socket server with eight channels, eight 16GB RDIMMs deliver 128GB of uniform high-bandwidth memory, minimizing latency and maximizing throughput for parallel computations. Never mix ranks or capacities to ensure deterministic performance in tightly coupled simulations.
Server-grade, rigorously tested compatible with Dell PowerEdge R720/R730 and HPE ProLiant Gen8/Gen9 systems.
Q: Can I mix this MT36JSF2G72PZ-1G9E1KF with other memory modules of different brands or speeds?
A: Mixing RDIMMs is strongly discouraged. Mismatched brands, speeds, or ranks often cause server instability, ECC errors, or boot failures. Always populate identical modules for mission-critical reliability.
Q: Is this memory compatible with my Intel Xeon E5 v1/v2 or AMD Opteron server platform?
A: Yes, if your server uses DDR3-1866 Registered ECC RDIMMs. This 1.5V module is validated for Intel C600 and equivalent AMD G34/C32 platforms. Confirm your system's Qualified Vendor List for compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server manual's memory population sequence. Typically, populate in sets of four identically-ranked RDIMMs per channel, starting with the blue slots. This dual-rank x4 module requires balanced loading across memory channels.
Q: Does this module support overclocking or XMP profiles?
A: No. As an ECC Registered server memory, it strictly adheres to JEDEC DDR3-1866 specifications. Overclocking and XMP are unsupported, as server platforms prioritize data integrity and 24/7 stability over variable clock speeds.
Q: What warranty and typical failure rate can I expect?
A: This module carries a one-year warranty. Enterprise-grade RDIMMs typically exhibit an annualized failure rate below 0.5%, ensuring reliable operation under continuous workloads when kept within specified thermal and voltage limits.
