This DDR3-1333 registered ECC module is purpose-built for legacy server platforms handling virtualization, in-memory databases, and mission-critical workloads where data integrity is non-negotiable. The dual-rank x4 organization drives improved memory interleaving for higher throughput, while the registered Command/Address architecture and ECC work in tandem to maintain signal stability and silently correct single-bit errors under sustained 24/7 operation.
1. ECC error correction silently detects and repairs single-bit faults in real time, preserving data integrity for transactional databases and financial processing workloads.
2. Registered signal type buffers the command and address bus, allowing fully loaded memory channels to operate stably and minimizing unplanned outages in dense virtualization clusters.
3. Dual Rank x4 organization interleaves accesses across internal bank groups, boosting effective channel utilization to sustain consistent throughput under heavy multi-tenant traffic.
4. The 1333MHz clock with PC3-10600 bandwidth delivers 10.6 GB/s per channel, preventing memory bottlenecks during concurrent data analytics and high-volume caching operations.
5. A 4 GB per module capacity provides a fine-grained scaling unit, enabling cost-efficient memory rightsizing for lightweight containers and small virtual machines without wasting provisioned resources.
When deploying mission-critical servers, every component must be deliberately chosen. The Micron MT36JSZF51272PY-1G4 is a 4GB DDR3-1333 Registered DIMM with ECC, explicitly engineered for servers where stability and data integrity trump raw speed. Its ECC capability actively corrects single-bit errors, a silent threat that can corrupt virtualization clusters or in-memory databases. For a VMware host running dozens of virtual machines, this means preventing random crashes and safeguarding transactional consistency. The registered design employs an on-board buffer to stabilize address and command signals, allowing you to populate all memory channels without signal degradation. This is non-negotiable for scaling memory-hungry database servers like Redis or SAP HANA, where large capacities are needed to keep hot datasets in RAM. Dual-rank x4 organization further amplifies performance via bank interleaving, boosting bandwidth for concurrent read/write operations that accelerate query response times under heavy loads. Complemented by a predictable 1333MHz clock and CL9 latency, this module delivers consistent, battle-tested reliability, ensuring your server infrastructure runs uninterrupted when every computational moment counts.
General Virtualization
For efficient virtual machine density, populate all memory channels identically to balance load. With 4 GB RDIMMs, start with at least six modules per CPU (24 GB) for light workloads, scaling to 12 or more modules (48 GB) to avoid swapping under moderate multi-VM environments. Always install in matched sets per memory controller to enable ECC and maintain stability.
In-Memory Database
In-memory databases demand capacity over speed, so maximize total RAM using the largest supported configurations of these 4 GB modules. Aim for 128 GB or more by fully populating all DIMM slots (e.g., 16 modules of 4 GB each) to keep entire datasets resident, significantly reducing storage I/O latency. Dual-rank x4 modules improve signal integrity at high densities, but verify system-specific population order to maintain performance.
HPC
HPC clusters favor memory bandwidth for parallel processing; populate every memory channel with identical modules to sustain peak throughput. A typical dual-socket node with three channels per CPU benefits from six 4 GB RDIMMs (24 GB) or twelve modules (48 GB) for memory-bound simulations, ensuring balanced NUMA access. Registered ECC is critical here to correct transient errors during long-running computational jobs.
Rigorously tested server memory. Compatible with Dell PowerEdge R710, HP ProLiant DL380 G7, IBM System x3650 M3, etc.
Q: Can I mix this MT36JSZF51272PY-1G4 with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is strongly discouraged. For server reliability, all installed DIMMs should match in speed, rank, latency, and voltage. Mismatched modules may cause system instability or failure to boot.
Q: Is this memory compatible with my system?
A: This DDR3-1333 ECC Registered DIMM is designed for servers based on Intel Xeon 5500/5600 series or AMD Opteron 6100 series platforms that accept 1.5V RDIMMs. Please consult your motherboard's qualified vendor list to confirm compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs across memory channels per CPU, starting with the slots farthest from the processor. For triple-channel architectures, install in groups of three; for dual-channel, use matched pairs. This ensures balanced interleaving and maximum throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant server Registered ECC DIMM built for data integrity and stability. It does not support overclocking or XMP extensions, as server environments prioritize error-free operation over frequency adjustments.
Q: What warranty and typical failure rate can I expect?
A: The module includes a 1-year warranty. Enterprise RDIMMs like this typically have an annualized failure rate well below 1% under normal operating conditions, providing dependable performance for critical workloads.
