Engineer's Note

This 64GB DDR4-3200 RDIMM is a server-class memory module purpose-built for virtualized environments, in-memory databases, and data-intensive enterprise workloads that demand high capacity and uncompromising data integrity. Leveraging a registered signal architecture with full ECC and a dual-rank x4 organization, it ensures superior signal stability on heavily loaded memory channels and maximizes interleaving efficiency for consistent throughput in dual-socket server platforms.

Technical Specs & Insights

1. A 64 GB capacity per module dramatically increases memory density per server node, enabling robust virtualization footprints and smoother operation of large in-memory databases without frequent scaling out.
2. Operating at a 3200 MHz data rate, it supplies the sustained high bandwidth necessary for real-time analytics and transactional workloads that cannot tolerate data bottlenecks.
3. Integrated ECC actively corrects single-bit errors in the background, preserving end-to-end data integrity for financial records and mission-critical enterprise applications.
4. The registered signal architecture reinforces command and address stability across fully populated channels, delivering the reliable uptime expected in high-availability data center deployments.
5. A Dual Rank x4 organization leverages bank interleaving to keep the memory pipeline saturated, which translates into consistent virtual machine responsiveness under peak consolidation loads.

Why These Specs Matter

The Micron MTA36ASF8G72PZ-3G2R is a server-grade 64 GB DDR4-3200 RDIMM purpose-built for data centers where integrity and uninterrupted operation define the business. In a dense virtualization cluster, its registered architecture actively buffers command and address signals, allowing you to fully populate servers with dozens of VMs while eliminating the signal degradation that would destabilize unbuffered memory. ECC error correction runs silently in the background, protecting hypervisor page tables and guest data from single-bit upsets that cause silent corruption—a critical safeguard when a flipped bit in a financial batch or a customer record goes unnoticed until it triggers a costly incident. For in-memory databases like SAP HANA or a high-frequency Redis cache, the dual-rank x4 organization enables rank interleaving that overlaps refresh cycles and saturates the 3200 MT/s bandwidth, so millions of database queries complete with predictable low latency instead of stalling under load. The 1.2 V supply and CL22 timing further strike an exact balance between power-conscious operation and responsive access, directly lowering cooling demands in multi-node rack deployments. Every one of these characteristics translates your infrastructure investment into hardened application availability—the peace of mind that data errors, virtual machine stalls, and thermal runaway are engineered out of the equation.

Endurance & Reliability

This 64GB DDR4-3200 Registered ECC RDIMM is a server-grade module. Capacity planning guidance for typical workloads follows.

General Virtualization
Install at least four identical modules (256 GB) evenly across the memory channels to maintain symmetrical NUMA access and solid bandwidth. For dense consolidation, scale to eight or twelve modules (512–768 GB) to avoid hypervisor swapping and keep virtual machines responsive under heavy multi-tenancy.

In-Memory Database
Populate all available DIMM slots with these 64 GB RDIMMs to build a multi-terabyte footprint that holds entire datasets in RAM. Standardize on the same dual‑rank, registered DIMMs across sockets to guarantee predictable latency, full ECC coverage, and stability under sustained high‑throughput loads.

High-Performance Computing
For maximum speed, configure one DIMM per channel (1DPC) to sustain the full 3200 MT/s data rate, delivering up to 256 GB per socket across eight channels. When capacity outweighs pure bandwidth, move to two DIMMs per channel (2DPC); the memory may downshift to 2933 MT/s, but dual‑rank interleaving still provides strong aggregate throughput for memory‑intensive simulations.

Verified Compatibility

This 64GB DDR4 RDIMM is rigorously tested and compatible with Dell PowerEdge R750, HPE ProLiant DL380 Gen10 Plus, Lenovo ThinkSystem SR650 V2.
