Product Overview

The Micron MTA72ASS8G72LZ-2G61ZR is a 64GB DDR4 Load-Reduced DIMM (LRDIMM) operating at 2666MHz with CL19 latency, built on 8Gbit die technology in a 4Rx8 configuration. Designed for enterprise-grade servers, this single-pack module delivers the maximum memory density required by modern workloads that demand large addressable RAM pools. As a brand-new, factory-sealed unit, it meets the stringent reliability standards expected by data centres, cloud operators, and enterprise IT teams across the GCC and beyond.

Key Features & Benefits

• 64GB High-Density Capacity: Maximises memory per slot using 8Gbit DRAM die technology, enabling servers to reach multi-terabyte total memory configurations without additional slots.
• DDR4-2666 (PC4-21300) Speed: Delivers 21.3 GB/s peak theoretical bandwidth per module, supporting fast data access for latency-sensitive enterprise applications.
• Load-Reduced (LRDIMM) Architecture: The buffer chip reduces the electrical load on the memory controller, enabling higher DIMM counts per channel and greater overall system memory capacity compared to RDIMMs.
• ECC Error Correction: 72-bit bus width (64-bit data + 8-bit ECC) provides hardware-level single-bit error correction and multi-bit error detection, critical for non-stop enterprise operations.
• 1.2V Low-Voltage Operation: Optimised power consumption reduces thermal output and operating costs in high-density server environments where hundreds of DIMMs may be deployed simultaneously.

Technical Architecture

Built on a 288-pin DDR4 DIMM form factor, this module uses a 4-rank, x8 organisation (4Rx8) that maximises storage density per module. The LRDIMM design incorporates a data buffer (DB) and register clock driver (RCD) that isolate the DRAM load from the memory bus, enabling platforms to populate more DIMMs per channel than RDIMM designs allow. The 8Gbit monolithic die architecture ensures consistent electrical characteristics across the module, supporting the tight timing tolerances required for CL19-19-19 operation at DDR4-2666 speeds.

Performance & Capacity

At DDR4-2666 with a 64-bit wide data bus, each module delivers up to 21.3 GB/s of theoretical peak bandwidth. In a dual-channel configuration, two modules provide over 42 GB/s, and in typical 8-channel server platforms such as dual-socket Intel Xeon Scalable or AMD EPYC systems, full population enables hundreds of GB/s of aggregate memory bandwidth. The 64GB capacity per DIMM allows a 24-slot server to reach 1.5TB of total installed memory, meeting the demands of the most memory-intensive enterprise workloads.

Compatibility & Integration

The MTA72ASS8G72LZ-2G61ZR is compatible with a broad range of enterprise server platforms that support DDR4 LRDIMMs, including Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem, Supermicro, and Fujitsu PRIMERGY server lines. It adheres to JEDEC DDR4 standards and is validated for use in systems with Intel Xeon Scalable (Skylake, Cascade Lake, Ice Lake) and select AMD EPYC processors. Before deployment, administrators should verify platform-specific Qualified Vendor Lists (QVLs) to confirm slot population rules and maximum supported memory configurations.

Ideal Use Cases

• Virtualisation & Private Cloud: Large RAM pools are essential for hosting hundreds of virtual machines per physical host; 64GB LRDIMMs maximise VM density on VMware vSphere, Microsoft Hyper-V, and KVM-based platforms.
• In-Memory Databases: Workloads such as SAP HANA, Oracle TimesTen, and Redis Enterprise require terabytes of low-latency RAM; high-density LRDIMMs make these deployments economically feasible.
• High-Performance Computing (HPC): Scientific modelling, financial risk analysis, and AI/ML training tasks benefit from the wide memory bandwidth and large working-set capacity this module provides.
• Enterprise Data Warehousing & Analytics: Real-time BI platforms and columnar databases like Vertica and SAP BW perform best when entire datasets reside in RAM, making maximum DIMM density a key infrastructure requirement.
