This 64GB DDR4-2666 Registered ECC RDIMM is engineered for enterprise server platforms handling memory-intensive workloads such as virtualization, in-memory databases, and high-availability applications, where its Quad Rank x4 configuration maximizes capacity per channel and registered buffering ensures robust signal integrity across fully populated DIMM slots. The built-in ECC and 1.2V low-power operation collaboratively protect data integrity and improve energy efficiency in always-on, mission-critical environments.
1. 64GB per module maximizes memory density in server nodes, enabling more virtual machines per physical host and reducing costly data center footprint.
2. ECC error correction silently detects and fixes single-bit memory errors, safeguarding transactional data integrity in mission-critical databases and financial applications.
3. Registered signal buffering stabilizes high-capacity memory configurations, allowing fully loaded server boards to operate reliably under heavy concurrent access loads.
4. Quad Rank x4 organization leverages rank interleaving to boost effective memory bandwidth, essential for analytics workloads that stream large datasets continuously.
5. 2666MHz memory speed delivers a balanced throughput for virtualized environments, keeping latency-sensitive applications responsive without exceeding power budgets in dense server racks.
For data centers and enterprise servers, the MTA72ASS8G72PSZ-2S6G1QG module embodies four critical characteristics that translate directly into operational resilience and performance. Its massive 64GB capacity empowers dense virtualization clusters, letting you run far more virtual machines per host without resorting to crippling disk swap, while in-memory databases like SAP HANA can hold entire working sets for real-time analytics. ECC technology actively corrects single-bit errors triggered by cosmic radiation or electrical interference, preserving transactional integrity in financial ledgers and preventing silent data corruption that could otherwise poison critical records. The Registered DIMM architecture buffers command and address signals, enabling fully populated memory channels with multiple DIMMs while sustaining unwavering signal stability—essential when dozens of VMs contend for resources on a single physical server. Finally, the quad-rank x4 organization amplifies effective bandwidth through rank interleaving, dramatically accelerating parallel database queries and complex analytical workloads where every nanosecond of latency compounds across millions of operations. Together, these attributes mean fewer crashes, higher consolidation ratios, and predictable, fortified uptime for the mission-critical services your enterprise depends on.
Memory Type Identification
This 64 GB DDR4-2666 module features ECC, Registered (RDIMM) signaling, and a quad-rank x4 organization, unequivocally classifying it as a server-grade memory module.
General Virtualization
Install at least four modules (256 GB total) evenly across the memory channels to support dense virtual machine consolidation without resource contention. In dual-socket systems, populate two DIMMs per channel to maximize capacity while maintaining reliable memory interleaving and availability.
In-Memory Database
Max out all DIMM slots with these 64 GB RDIMMs to keep the entire dataset in RAM, targeting terabytes of capacity. A symmetrical population across all channels ensures uniform access latency, allowing the database engine to scale linearly without memory bottlenecks.
High-Performance Computing
For bandwidth-sensitive HPC workloads, deploy one module per memory channel—yielding 512 GB on an eight‑channel platform—to sustain the full 2666 MT/s speed. This configuration reduces rank loading and delivers the high throughput required for parallel simulations and large‑scale data analysis.
Rigorously tested for compatibility with Dell PowerEdge R740, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650, and similar servers.
Q: Can I mix this MTA72ASS8G72PSZ-2S6G1QG with other memory modules of different brands or speeds?
A: Mixing registered ECC modules from different brands or speeds is not recommended. It may cause system instability, unbootable states, or force all DIMMs to the lowest common speed and relaxed timings.
Q: Is this memory compatible with my system? It’s an Intel Xeon Scalable platform.
A: Yes, this 288-pin DDR4-2666 RDIMM is compatible with Intel Xeon Scalable (Purley) and similar platforms supporting registered ECC memory. Verify your board’s qualified vendor list for 64GB quad-rank x4 modules.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate according to your server’s memory slot numbering. Typically, install quad-rank DIMMs starting farthest from the CPU per channel, leaving one slot empty per channel to balance load and maintain 2666MT/s speeds.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant DDR4-2666 registered ECC module operating at 1.2V. It does not support XMP profiles or overclocking, as server memory prioritizes data integrity and stability over frequency manipulation.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Enterprise-grade RDIMMs like this have typical annualized failure rates below 0.5%, ensuring high reliability in properly cooled and managed server environments.
