Supermicro MEM-DR464L-HL02-ER29 64GB Memory Overview

The Supermicro MEM-DR464L-HL02-ER29 64GB 2933MHz PC4-23400 CL21 ECC Registered DDR4 SDRAM 288-Pin RDIMM memory belongs to a specialized category of enterprise-class server memory designed to support high-density workloads, mission-critical computing environments, and data-intensive applications. This category focuses on Registered DIMM (RDIMM) modules that deliver enhanced signal integrity, scalability, and reliability compared to unbuffered memory. RDIMM memory is widely deployed in rack servers, blade servers, and enterprise workstations where stability, error correction, and performance consistency are mandatory.

DDR4 SDRAM RDIMM memory modules operating at 2933MHz are engineered to balance bandwidth efficiency and power optimization. This category addresses the needs of data centers, virtualization clusters, private cloud infrastructures, and enterprise IT environments that rely on predictable memory behavior under continuous load. The 64GB capacity places this product within the high-density memory segment, allowing servers to scale memory footprints without increasing physical DIMM slots.

DDR4 SDRAM Technology and Architectural Benefits

DDR4 SDRAM represents a significant evolution in memory architecture, delivering higher transfer rates, improved power efficiency, and enhanced reliability compared to previous generations. Memory modules in this category operate at lower voltages, typically 1.2V, which reduces overall power consumption and heat generation in densely populated server systems. This efficiency is particularly important in multi-socket server platforms where memory density and thermal management directly affect system stability.

The PC4-23400 specification indicates a theoretical peak bandwidth of 23.4GB per second per module, enabling faster data access for processors handling parallel workloads. This category of DDR4 memory is optimized for modern server CPUs that rely on high memory throughput to maximize core utilization. The architectural improvements in DDR4 also support higher module densities, allowing 64GB RDIMM modules to operate reliably at scale.

Registered DIMM Signal Integrity Enhancements

Registered DIMM technology introduces a register between the memory controller and the DRAM chips, which buffers address and command signals. This design significantly improves signal integrity, especially when multiple memory modules are installed across several channels. The category of RDIMM memory is essential for enterprise servers that require large memory configurations, as it reduces electrical load on the memory controller and ensures stable operation.

The buffered design allows server platforms to populate more DIMM slots per channel without sacrificing performance or reliability. This makes RDIMM memory the preferred choice for database servers, virtualization hosts, and analytics platforms that demand high memory capacity with consistent performance characteristics.

64GB High-Density Memory Configuration Advantages

The 64GB capacity defines a premium segment within the RDIMM memory category, offering substantial memory resources per module. High-density memory configurations enable IT administrators to achieve greater total system memory with fewer modules, optimizing slot utilization and simplifying system design. This is especially beneficial in compact server chassis where physical space is limited.

High-capacity modules reduce the need for frequent memory upgrades and support long-term scalability. Servers equipped with 64GB RDIMM modules can accommodate memory-intensive applications such as in-memory databases, large-scale virtualization, and real-time analytics without constant hardware changes.

Memory Scalability in Multi-Socket Server Platforms

Multi-socket servers benefit significantly from high-density RDIMM memory. By using 64GB modules across multiple memory channels, systems can achieve several terabytes of total memory capacity. This category of memory supports balanced memory distribution across CPUs, reducing NUMA latency and improving application responsiveness.

Scalability is further enhanced by compatibility with enterprise server chipsets that support advanced memory interleaving and error correction features. The ability to scale memory efficiently ensures that server infrastructure can adapt to evolving workload requirements.

2933MHz Performance Characteristics and Bandwidth Efficiency

Operating at 2933MHz, this category of DDR4 RDIMM memory provides a strong balance between speed and stability. The 2933MT/s data rate is widely supported by modern server processors, making it an optimal choice for enterprise deployments seeking reliable high-speed memory. This frequency enables improved data throughput for applications that rely on fast memory access.

Memory operating at this speed is well-suited for virtualization environments where multiple virtual machines compete for memory bandwidth. The consistent performance ensures predictable response times and efficient resource allocation across workloads.

Latency Considerations and CL21 Timing

The CL21 latency rating reflects a carefully engineered balance between speed and reliability. In server environments, stability and error-free operation often take precedence over ultra-low latency. This category of memory prioritizes consistent performance under sustained workloads, making it ideal for enterprise applications that require continuous uptime.

Latency characteristics are optimized to work in harmony with registered buffering and ECC functionality, ensuring that data integrity is maintained without compromising throughput.

ECC Memory for Data Integrity and Reliability

Error Correcting Code (ECC) memory is a defining feature of enterprise RDIMM categories. ECC functionality detects and corrects single-bit memory errors while identifying multi-bit errors, preventing data corruption and system crashes. This capability is critical in environments where data accuracy and system stability are paramount.

Servers operating in financial services, healthcare, scientific research, and enterprise databases rely on ECC memory to maintain data integrity during long processing cycles. This category of memory ensures that transient errors caused by electrical interference or cosmic radiation do not compromise system reliability.

Enterprise Workload Protection

ECC memory significantly reduces the risk of silent data corruption, which can lead to inaccurate computations or system failures. By integrating ECC technology, RDIMM memory modules provide an additional layer of protection for mission-critical applications that operate continuously.

This level of reliability is essential for systems running virtualization platforms, transactional databases, and large-scale data processing workloads where even minor errors can have significant consequences.

288-Pin RDIMM Form Factor Compatibility

The 288-pin RDIMM form factor is the industry standard for DDR4 server memory. This category of memory is designed to fit enterprise-grade server motherboards that support registered DDR4 DIMMs. The standardized pin layout ensures broad compatibility across a wide range of Supermicro and industry-standard server platforms.

Form factor consistency simplifies system integration and upgrades, allowing IT teams to deploy memory modules confidently without compatibility concerns. The physical design also supports robust thermal management, which is crucial in high-density server configurations.

Thermal Stability and Power Efficiency

DDR4 RDIMM memory modules are engineered for thermal stability in densely populated server environments. Operating at lower voltages than previous generations, this category of memory reduces heat output and improves overall system efficiency. Efficient thermal performance contributes to longer component lifespan and reduced cooling costs.

Power efficiency is especially important in data centers where energy consumption directly impacts operational expenses. RDIMM DDR4 memory helps organizations achieve better performance-per-watt ratios.

Supermicro Memory Qualification and Platform Optimization

Supermicro memory modules are specifically designed and qualified for use in Supermicro server platforms.
