Engineer's Note

This RDIMM with ECC and registered signal type is engineered for enterprise servers and memory-intensive workloads such as virtualization, in-memory databases, and mission-critical applications where data integrity is paramount. Its dual-rank x4 configuration maximizes interleaving and memory bandwidth efficiency at 3200 MHz, while the registered buffer ensures stable operation across densely populated 288-pin channels, and ECC provides robust single-bit error correction to prevent data corruption.

Technical Specs & Insights

1. Registered signal type stabilizes command and address buses under heavy load, allowing dense memory populations without compromising data center uptime.
2. ECC error correction eliminates single-bit faults in real time, protecting transactional integrity for databases and financial services that cannot tolerate silent corruption.
3. 64 GB capacity per module maximizes virtual machine density per rack unit, directly lowering cloud infrastructure cost per tenant.
4. 3200 MHz speed boosts memory bandwidth to the sweet spot for in-memory analytics, cutting query latency on large datasets during concurrent user spikes.
5. Dual rank x4 organization interleaves requests across internal banks, keeping server memory channels saturated for consistent throughput in heavily consolidated workloads.

Why These Specs Matter

The Micron MTA36ASF8G72LZ-3G2 is a 64GB DDR4-3200 registered RDIMM, purpose-built for enterprise servers and data center workloads. In high-density virtualization clusters, its registered architecture buffers command and address signals, which stabilizes large memory populations and prevents signal degradation as you scale up VM hosts. Paired with ECC error correction, the module actively detects and corrects single-bit flips that can silently corrupt hypervisor state or transactional data—an essential defense when a single undetected error could bring down dozens of tenant applications. The dual-rank x4 organization interleaves memory accesses across internal banks, boosting sustained bandwidth and lowering effective latency for throughput-hungry workloads. For an in-memory database like Redis or SAP HANA, this translates directly into higher queries per second and consistent response times under load, because the module can service overlapping read and write streams without stalling. With a 3200 MT/s transfer rate and 1.2V energy efficiency, it also keeps the power envelope manageable across fully populated 24-slot servers, reducing thermal strain and TCO in always-on environments where reliability, density, and data integrity are non-negotiable.

Endurance & Reliability

General Virtualization
This 64GB DDR4-3200 RDIMM is ideal for dense virtualization hosts. A dual-socket server populated with 8 identical modules (512GB total) comfortably supports 50+ moderate VMs. Configure memory in balanced channels per CPU to avoid NUMA bottlenecks and maintain consistent latency under mixed workloads.

In-Memory Database
For in-memory databases like Redis or SAP HANA, capacity and reliability are paramount. Install 16 of these 64GB ECC registered DIMMs to achieve 1TB per host, enabling large datasets to reside entirely in RAM. Populate all memory channels symmetrically and enable mirroring or sparing if the platform requires extra resilience against uncorrectable errors.

High-Performance Computing
HPC clusters demand maximum bandwidth and low latency. Use multiples of 8 modules per 8-channel CPU (e.g., 256GB) to saturate memory interleaving and fully utilize the 3200MT/s speed. The dual-rank x4 design delivers superior signal integrity for sustained floating-point throughput in simulation and modeling workloads.
