Engineer's Note

This is a server-class DDR4 RDIMM module, ideally suited for virtualization platforms, in-memory databases, and any mission-critical workloads demanding high data integrity. Its Registered signal type and ECC error correction combine to ensure exceptional signal stability on densely populated motherboards, while the Dual Rank x4 configuration maximizes memory bandwidth efficiency for sustained heavy loads.

Technical Specs & Insights

1. High-density module supports expansive virtual machine deployments, maximizing consolidation ratios and freeing up rack space in data centers.
2. Error-correcting code protection eliminates single-bit memory errors silently causing data corruption, essential for financial transactions and mission-critical databases.
3. Registered buffer isolates the command and address bus from the DRAM chips, enabling robust signal integrity for fully populated large-capacity servers without compromising uptime.
4. Dual Rank x4 organization keeps per-channel bandwidth saturated through interleaving, delivering consistent performance under heavy multi-tenant workloads.
5. Elevated memory frequency accelerates in-memory compute and real-time analytics, reducing response times for latency-sensitive enterprise applications.

Why These Specs Matter

The Micron MTA36ASF8G72LZ-3G2B1R is a 64GB DDR4-3200 Registered ECC DIMM engineered for server workloads. Its ECC capability eliminates a key risk: silent data corruption. In a virtualized cluster, a single uncorrected bit flip can corrupt a database record or crash a service; ECC corrects these errors in real time, preserving uptime for your mission-critical services. The registered buffer is just as crucial—it buffers command and address signals, letting you populate every DIMM slot without signal degradation. This enables the multi-terabyte memory footprints required by hypervisors to maximize VM density. The module’s dual-rank design and 64GB capacity amplify bandwidth by interleaving memory banks. When powering an in-memory database like Redis or SAP HANA, this interleaving, paired with the 3200 MT/s speed, delivers the consistent low latency and high throughput that keep real-time analytics responsive under load. Ultimately, these characteristics mean greater consolidation, faster data insights, and absolute reliability for your data center.

Endurance & Reliability

General Virtualization
For dense VM consolidation, deploy this 64GB RDIMM in a balanced six- or eight-channel population to maximize memory bandwidth while retaining spare capacity. A dual-socket server with 16 modules (1TB total) comfortably hosts over 100 moderate VMs, and you can scale by populating half the slots initially and adding identical DIMMs later without sacrificing interleaving.

In-Memory Database
In-memory databases like SAP HANA or Redis demand both capacity and data integrity, making ECC registered memory mandatory. Start with eight 64GB DIMMs (512GB) per socket for mid-sized workloads and scale to 24 modules (1.5TB) to keep entire datasets in RAM, configuring symmetrical ranks across memory channels to avoid NUMA penalties.

High-Performance Computing
HPC clusters benefit from balanced memory-per-core ratios: install one 64GB DIMM per channel to sustain memory bandwidth during large-scale simulations. For compute nodes with 128 cores, populate all 16 slots with 64GB RDIMMs (1TB) to deliver over 200GB/s of sustained bandwidth, and always match module part numbers to prevent clock skew in registered designs.
