Designed for legacy server platforms requiring reliable operation, this Micron 4GB DDR3-1333 Registered ECC RDIMM (PC3-10600, CL9, 1.5V) ensures data integrity in virtualized environments and light in-memory databases. Its dual-rank x4 configuration with 240-pin registered signaling enhances signal stability on densely populated motherboards, while ECC actively corrects single-bit errors to prevent silent data corruption in mission-critical workloads.
1. Registered signal type buffers command and address lines, allowing the server to support higher memory densities without compromising signal integrity across fully loaded channels.
2. ECC error correction detects and corrects single-bit faults in real time, shielding virtualized databases and critical applications from silent data corruption.
3. Dual rank x4 organization enables rank interleaving that maximizes channel utilization, boosting throughput for concurrent virtual machines and memory-intensive analytics.
4. DDR3 technology provides a proven, energy-efficient foundation for legacy enterprise servers, ensuring seamless drop-in compatibility with older backplanes and processors.
5. 1333MHz operation delivers dependable bandwidth per channel for steady transactional workloads, keeping response times predictable under moderate multi-tenant pressure.
The Micron MT36JSZF51272PY-1G4D1BA is a 4GB DDR3-1333 Registered RDIMM engineered for servers where reliability dictates business continuity. Its ECC circuitry actively corrects single-bit memory errors in real time—a critical safeguard for in-memory databases like Redis or SAP HANA, where a flipped bit could silently corrupt transactional records and lead to costly analytical discrepancies. The registered buffer on the module stabilizes address and command signals, enabling your virtualization cluster to populate all DIMM slots without signal degradation. This lets you run dozens of VMs per host, scaling memory capacity without random reboots under heavy load. The dual-rank x4 organization interleaves memory banks to boost effective bandwidth; when multiple VMs compete for data, the module delivers higher throughput and lower latency, keeping applications responsive. Operating at 1.5V with CL9 latency, it strikes the proven balance of performance and power efficiency that data centers demand for 24/7 operation.
General Virtualization
For general virtualization, populate all memory channels symmetrically with these 4GB ECC Registered DIMMs—install at least one module per channel, e.g., six DIMMs for 24GB in a triple-channel server or eight DIMMs for 32GB in quad-channel systems. This ensures interleaved memory access, provides ample capacity for multiple VMs, and avoids bandwidth bottlenecks from empty channels.
In-Memory Database
To serve in-memory databases, maximize capacity by fully populating every DIMM slot. In a dual-socket server with 24 slots, install 24 of these 4GB modules to achieve 96GB, suitable for moderate datasets. Always balance modules across memory controllers for optimal interleaving and low latency.
High-Performance Computing
HPC requires peak bandwidth: configure symmetric populations with identical 4GB RDIMMs in all channels. For an 8-channel node, use two modules per channel for 64GB to exploit channel interleaving. Even at 1333MHz, the combined bandwidth from multiple channels effectively supports memory-bound MPI jobs; never mix ranks or leave channels unbalanced.
Rigorously tested server memory, compatible with Dell PowerEdge R710, HP ProLiant DL380 G7, and similar platforms.
Q: Can I mix this MT36JSZF51272PY-1G4D1BA with other memory modules of different brands or speeds?
A: Mixing is not recommended. Server platforms require identical RDIMM specifications. Combining different brands, speeds, or ranks can cause POST failures, signal integrity issues, and invalidate your system stability.
Q: Is this memory compatible with my Intel Xeon or AMD Opteron server platform?
A: This DDR3-1333 Registered ECC RDIMM is compatible with dual-processor platforms supporting 1.5V operation, such as Intel 5500/5600 series or AMD G34/C32 chipsets. Verify your board’s qualified vendor list.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs in sets of three per memory channel. Follow your server manual: start with slots A1, B1, C1 for triple-channel balance. All channels must use matched dual-rank x4 RDIMMs for best throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a registered server DIMM built to strict JEDEC standards. It does not support overclocking, voltage adjustments, or XMP profiles. It operates solely at 1.5V, DDR3-1333, CL9 for guaranteed stability.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Typical annualized failure rate is well below 0.5% in controlled server environments, provided proper ESD handling and cooling per ASHRAE guidelines are maintained.
