This 64GB DDR4-2400 Registered ECC RDIMM is purpose-built for enterprise servers and workstations handling virtualization and memory-intensive database workloads. The Quad Rank x4 architecture, paired with registered signal buffering, ensures robust data integrity and exceptional signal stability in high-density memory configurations.
1. The massive memory capacity allows a single server to host hundreds of virtual machines, drastically raising consolidation ratios without sacrificing performance.
2. ECC protection corrects single-bit errors and detects multi-bit corruption in real time, preserving data integrity for financial transactions and critical databases.
3. Registered signal buffering stabilizes high-density memory configurations, enabling fully populated server boards to operate reliably under 24/7 workloads.
4. Quad Rank architecture maximizes memory density per module, letting data centers pack more RAM into constrained slot counts for large in-memory datasets.
5. The PC4-19200 bandwidth delivers smooth throughput for concurrent analytics streams, preventing memory bottlenecks when multiple cores request data simultaneously.
The Micron MTA72ASS8G72LZ-2G3 is a 64GB DDR4-2400 registered ECC memory module built specifically for enterprise servers, and its four defining characteristics directly address the critical pain points of data center operators. The ECC functionality actively detects and corrects single-bit memory errors caused by cosmic radiation or electrical interference. In a dense virtualization cluster hosting dozens of virtual machines, even one uncorrected bit flip can silently corrupt a financial transaction or a customer record, so this real‑time error correction guards the data integrity your business depends on.
The registered signal type buffers command and address lines, stabilizing the electrical load across high‑capacity configurations. When you populate a server with multiple 64GB DIMMs to support memory‑hungry in‑memory databases like SAP HANA or Redis, the register ensures clean signal distribution regardless of load, preventing intermittent crashes during peak transaction windows. Combined with quad‑rank x4 organization that maximizes interleaving, this module sustains higher sustained bandwidth under heavy concurrency. For database engineers, that translates into faster query responses and more consistent virtual machine performance, directly improving user experience and SLA compliance. It turns raw specifications into measurable operational resilience.
Capacity Planning Guide for 64GB DDR4-2400 ECC Registered RDIMM
This is a server-grade ECC Registered DIMM designed for reliable, high-density deployments.
General Virtualization
Populate all memory channels symmetrically for optimal throughput. In a dual-socket server with eight total channels, one 64GB DIMM per channel delivers 512GB, comfortably hosting 30–50 moderate VMs. Because of the quad-rank design, adding a second DIMM per channel often throttles speed to 2133MHz—balance density and frequency based on consolidation needs.
In-Memory Database
Maximize capacity and data integrity. Install one DIMM per channel to maintain the full 2400MHz speed; a 16-slot platform yields 1TB, with ECC guarding against bit-errors critical for datasets. For extreme capacity, populate two DIMMs per channel to reach 2TB, accepting a minor speed reduction while the registered buffer ensures stable operation.
High-Performance Computing (HPC)
Sustained bandwidth is paramount. Use exactly one quad-rank 64GB module per memory channel to keep 2400MT/s, delivering roughly 19.2GB/s per channel. An eight-channel platform achieves over 150GB/s aggregate throughput. Deploy identical modules across all channels to eliminate NUMA imbalances and maximize parallel simulation efficiency.
Rigorously tested, this 64GB DDR4-2400 RDIMM fits Dell PowerEdge R740, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650.
Q: Can I mix this MTA72ASS8G72LZ-2G3 with other memory modules of different brands or speeds?
A: Mixing RDIMMs is not recommended. This module's registered ECC design and quad rank configuration require matched sets to maintain signal integrity and reliable server operation. Mismatched specs can cause instability.
Q: Is this memory compatible with my Intel Xeon or AMD EPYC server platform?
A: This 64GB DDR4-2400 ECC RDIMM is compatible with most Intel Xeon E5-2600 v3/v4 and scalable platforms, and select AMD EPYC systems. Always verify your server's qualified vendor list for RDIMM support.
Q: What is the recommended DIMM population order for optimal performance with this quad rank module?
A: Populate identical DIMMs in sets per memory channel, starting with the first slot of each channel. For quad rank modules, balanced loading across memory controllers is critical; consult your server's population guide.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-class registered ECC DIMM, it strictly adheres to JEDEC DDR4-2400 standards for stability and data integrity. Overclocking or XMP is not supported and could compromise system reliability.
Q: What warranty and typical failure rate can I expect for this enterprise memory?
A: It includes a one-year warranty. Enterprise RDIMMs like this Micron module have a typical annualized failure rate (AFR) well below 0.5%, ensuring high reliability for mission-critical workloads.
