Engineer's Note

Designed for server platforms handling memory-intensive workloads such as virtualization and in-memory databases, this 64 GB DDR4-3200 RDIMM leverages ECC and registered signaling to ensure data integrity and signal stability in dense, multi-DIMM configurations. Its dual-rank x4 organization strikes an optimal balance between capacity and memory bandwidth, making it particularly effective for sustained throughput under heavy concurrent access.

Technical Specs & Insights

1. ECC memory continuously detects and corrects single-bit errors, safeguarding data integrity for mission-critical server workloads and financial transactions.
2. Registered memory buffers command and address signals, enabling stable operation with high-capacity configurations essential for large-scale virtualization.
3. With 64 GB per module, this memory allows dense server packing, maximizing virtual machine density without sacrificing performance.
4. DDR4-3200 speed delivers high memory bandwidth, ensuring rapid data access for in-memory databases and real-time analytics.
5. Dual Rank x4 organization interleaves memory accesses across two ranks, enhancing throughput and maintaining consistent performance under heavy multi-threaded server loads.

Why These Specs Matter

Every component in your data center must earn its place. The Micron MTA36ASF8G72LZ-3G2F1 64GB DDR4-3200 RDIMM delivers four capabilities that directly impact your most demanding workloads. In a dense virtualization cluster, its ECC corrects single-bit errors seamlessly, preventing silent corruption that could crash VMs or corrupt a database instance without warning. The registered buffer re-drives command and address lines for rock-solid stability even with all 24 DIMM slots populated, letting you scale memory to terabytes confidently. For in-memory databases like Redis or SAP HANA, the 64GB capacity keeps entire hot datasets on a single module, slashing latency and licensing overhead. Most critically, the dual-rank x4 organization unleashes the full potential of 3200 MT/s: interleaved access across bank groups yields far higher effective throughput than a single-rank module. Complex queries return faster, and high-concurrency transaction processing remains fluid—because for your revenue, every millisecond of delay is lost opportunity.

Endurance & Reliability

General Virtualization
For dense virtualization hosts, this 64GB RDIMM is ideal. Deploy a balanced configuration, typically populating 8 or 16 identical modules across all memory channels to maximize bandwidth and capacity. Plan for 2–4 modules per CPU socket to comfortably support dozens of general-purpose VMs, leaving headroom for memory overcommitment and live migration.

In-Memory Database
Low-latency in-memory databases like Redis or SAP HANA demand both capacity and data integrity. Install a full set of 8 or 12 of these dual-rank ECC modules to reach 512GB or 768GB per node, ensuring all channels are populated for peak throughput. The registered ECC design guarantees end-to-end error correction, which is critical for transactional consistency.

High-Performance Computing
HPC workloads thrive on memory bandwidth. Equip each node with one 64GB RDIMM per channel—typically 8 modules in a dual-socket server—to fully utilize the 3200MT/s speed. This configuration provides 512GB of registered ECC memory, balancing large per-core capacity with the sustained bandwidth required for simulation, modeling, and parallel I/O patterns.
