Supermicro MEM-DR464L-SL01-ER29 64GB Memory Overview

The Supermicro MEM-DR464L-SL01-ER29 64GB DDR4 RDIMM memory module is part of the enterprise-grade server memory category engineered for high reliability, scalability, and sustained performance in professional IT environments. This category focuses on DDR4 ECC Registered memory solutions designed specifically for servers and workstations that operate under continuous load and mission-critical conditions. Unlike consumer-grade memory, enterprise RDIMM memory is built to meet stringent requirements for data integrity, signal stability, and platform compatibility.

DDR4 Registered DIMM memory plays a fundamental role in modern data center architecture by enabling higher memory capacities and improved system stability. The inclusion of a register between the memory controller and DRAM chips allows servers to support more memory modules per channel without electrical degradation. This architectural advantage makes RDIMM memory essential for multi-socket servers, virtualization platforms, cloud infrastructures, and enterprise databases.

Positioning Within the DDR4 SDRAM Ecosystem

Within the broader DDR4 SDRAM ecosystem, this memory category occupies a performance-optimized and reliability-focused segment. DDR4 technology offers higher data transfer rates and lower operating voltage compared to previous DDR3 generations, making it more suitable for power-efficient and high-density deployments. The Supermicro 64GB DDR4 RDIMM module operates at 2933MHz, aligning with a widely supported speed tier across enterprise server platforms.

This speed class ensures broad compatibility while delivering sufficient bandwidth for demanding workloads. DDR4 RDIMM memory at 2933MHz is commonly deployed in balanced systems where performance, stability, and energy efficiency must coexist without compromise.

Error Correcting Code Registered Memory Architecture

Error Correcting Code Registered memory defines a critical subcategory within enterprise memory solutions. ECC functionality automatically detects and corrects single-bit memory errors during operation, significantly reducing the risk of data corruption and unexpected system failures. In environments where data accuracy is paramount, such as financial services, healthcare systems, and enterprise databases, ECC memory is not optional but a fundamental requirement.

The integration of ECC with registered buffering enhances both reliability and scalability. Registered memory reduces electrical load on the memory controller, while ECC ensures data integrity, creating a robust memory subsystem capable of supporting complex and long-running workloads.

Impact of ECC on System Reliability

ECC memory continuously monitors data integrity as information is written to and read from memory. By correcting errors in real time, ECC prevents silent data corruption that could otherwise propagate through applications and storage systems. This capability is especially important in virtualized environments where a single memory error could affect multiple virtual machines.

Enterprise IT infrastructures depend on predictable and stable operation. ECC Registered memory contributes directly to system uptime and operational continuity, making it a cornerstone of enterprise server design.

64GB High-Density Memory Classification

The 64GB capacity places this Supermicro memory module within the high-density server memory category. High-capacity DIMMs are essential for modern workloads that require large memory footprints, including virtualization clusters, in-memory databases, data analytics platforms, and enterprise resource planning systems.

Using high-density memory modules reduces the total number of DIMM slots required to achieve target memory capacities. This approach improves airflow, simplifies system configuration, and preserves expansion flexibility for future upgrades.

Advantages of Fewer High-Capacity DIMMs

Deploying fewer, larger-capacity RDIMM modules can improve overall system efficiency. Reduced DIMM counts lower power consumption associated with memory channels and minimize heat generation. This configuration strategy also decreases the complexity of memory population rules, making it easier to design and maintain enterprise server systems.

High-density memory modules support scalability by allowing organizations to increase memory capacity without replacing existing infrastructure, extending the lifespan of server investments.

DDR4 2933MHz Performance Characteristics
