This Micron VLP RDIMM module, with its registered signal type and ECC support, is engineered for server platforms where data integrity is critical, making it ideal for memory-intensive workloads like virtualization and in-memory databases. Its dual-rank x8 configuration at 1.35V low voltage and CL11 latency delivers efficient, stable 1600MT/s performance while the very low profile design excels in dense 1U and blade server deployments with constrained vertical clearance.
1. ECC protection catches and corrects single-bit memory errors instantly, safeguarding transactional data integrity in always-on enterprise servers.
2. Registered clocking buffers the command and address lines, stabilizing signal paths so dense memory configurations run reliably under continuous virtualization workloads.
3. Very Low Profile form factor fits seamlessly into space-constrained rackmount servers, optimizing airflow and reducing thermal buildup in high-density data centers.
4. Mainstream DDR3 data-rate delivers consistent bandwidth per channel, comfortably supporting concurrent database queries and light multi-tenant hosting environments.
5. Dual-rank organization enables rank interleaving, keeping memory pipelines fully utilized and improving effective throughput when multiple VMs access memory simultaneously.
When deploying business-critical workloads, the integrity and efficiency of your memory subsystem directly dictate uptime and performance. The Micron MT18KDF51272PDZ-1G6M1 is a server-grade VLP RDIMM, and its four defining characteristics solve real infrastructure pain points. ECC error correction proactively hunts down and corrects single-bit flips caused by background radiation—a silent threat that, without ECC, could corrupt a financial transaction or crash your virtualization hypervisor, taking dozens of virtual machines with it. The Registered signal buffer stabilizes address and command lines, letting you populate all 24 DIMM slots on a dual-socket board for dense memory pools without signal degradation, essential when an in-memory database like Redis demands consistent sub-millisecond latencies across hundreds of gigabytes. The Very Low Profile form factor fits seamlessly into 1U blade servers and compact nodes where standard modules would obstruct airflow, preventing cooling dead zones that cause throttling. Finally, 1.35V low-voltage operation cuts power consumption and thermal output, which is critical for colocation billing and prolonging component lifespan in a 24/7 virtualized cluster—saving you from premature hardware refresh and late-night heat-related outages. Each design choice is a deliberate safeguard for always-on IT environments.
This module is a server-grade DDR3L Registered ECC DIMM (VLP RDIMM). Below is the capacity planning guidance for typical server workloads using this 4 GB, 1600 MHz module.
General Virtualization
Populate one 4 GB module per memory channel in a dual-socket server—eight channels total—to achieve 32 GB per CPU and 64 GB overall. This balanced configuration guarantees full quad-channel bandwidth, stable latency for mixed VMs, and the 1.35 V low-voltage design helps sustain energy-efficient operations in consolidated environments.
In-Memory Database
For in-memory databases demanding maximum data protection, fill every available DIMM slot with these ECC modules. A 24-slot server delivers 96 GB of resilient capacity, ideal as a development node or a small dataset server. To scale further, cluster multiple low-voltage nodes; the reduced thermal footprint allows dense packing without compromising reliability.
High-Performance Computing (HPC)
Deploy two modules per channel (2DPC) to leverage dual-rank interleaving and memory burst performance. In a dual-socket quad-channel system, this yields 128 GB at full 1600 MT/s speed, providing the high bandwidth needed for compute-intensive simulations. The VLP form factor improves airflow in blade enclosures, while ECC and low power draw ensure data integrity over prolonged runs.
Rigorously tested server memory. Compatible with Dell PowerEdge R760, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650.
Q: Can I mix this MT18KDF51272PDZ-1G6M1 with other memory modules of different brands or speeds?
A: Mixing different brands is possible but not recommended. All modules must be DDR3-1600 Registered ECC with identical voltage and rank. Mixing speeds forces all to run at the lowest common speed, risking instability.
Q: Is this memory compatible with my system?
A: It is designed for server platforms supporting DDR3 Registered ECC, such as Intel Xeon E5-2600 or AMD Opteron 6300 series. Verify with your server's Qualified Vendor List and ensure the board accepts 240-pin VLP RDIMMs.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical modules per channel, filling slots farthest from the CPU first. For multi-channel platforms, balance memory across channels as specified in the server motherboard manual to maximize bandwidth and maintain interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-grade Registered ECC module, it strictly adheres to JEDEC DDR3-1600 standards for maximum stability and data integrity. XMP and overclocking are not supported and would compromise reliability.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Built with high-quality, rigorously tested components, the typical annualized failure rate (AFR) is well below industry average at around 0.2% under normal server operating conditions.
