MEM-DR564L-CL01-ER64 Supermicro 64GB DDR5 6400MHz RAM

High-Performance DDR5 Server Memory for Enterprise Workloads

The MEM-DR564L-CL01-ER64 Supermicro 64GB DDR5 6400MHz PC5-51200 CL52 ECC Registered 2Rx4 1.1V 288-Pin RDIMM Server Memory Module belongs to a new generation of high-speed server memory designed to meet the increasingly demanding requirements of enterprise IT infrastructures. This category of memory, often referred to as DDR5 ECC Registered RDIMM Server Memory, delivers unprecedented bandwidth, energy efficiency, and reliability.

DDR5 Technology: A Leap Forward from DDR4

As part of the fifth generation of Double Data Rate Synchronous Dynamic Random-Access Memory (DDR SDRAM), DDR5 delivers significant enhancements over its predecessor, DDR4. The DDR5 architecture includes improvements in data transfer rates, capacity scaling, power efficiency, and error correction features. The 6400MHz clock speed of this Supermicro module far surpasses traditional DDR4 speeds, which top out around 3200MHz.

Bandwidth and Transfer Rate Enhancements

With a data rate of PC5-51200, this memory module offers a peak transfer bandwidth of up to 51.2 GB/s per module. This allows servers to handle more data-intensive tasks simultaneously—ideal for workloads such as AI inference, real-time analytics, virtualization, high-frequency trading, and enterprise-level databases.

Reduced Latency and Higher Clock Speeds

Despite operating at significantly higher frequencies, DDR5 memory like this Supermicro module maintains a low CL52 CAS latency, making it highly responsive. This is critical in latency-sensitive environments such as data centers, research clusters, and financial modeling platforms.

ECC Registered RDIMM Architecture for Server-Grade Reliability

The ECC (Error-Correcting Code) and Registered DIMM (RDIMM) design play a critical role in maintaining data integrity. ECC is indispensable for server-grade memory because it automatically detects and corrects single-bit memory errors, thereby reducing data corruption risks. RDIMMs include a register between the memory controller and DRAM modules that help manage heavy workloads and enhance scalability.

2Rx4 Organization for Parallelism and Stability

This Supermicro 64GB DDR5 memory module uses a 2Rx4 rank structure, which allows for improved signal integrity and efficient data transfers. Multi-rank modules like this one help maximize the CPU memory channel utilization, especially when installed in multi-module configurations across dual or quad-channel architectures.

Low Voltage Operation for Energy Efficiency

Operating at just 1.1 volts, this DDR5 RDIMM consumes less power than older DDR4 equivalents (typically running at 1.2V), which leads to reduced thermal output and energy costs in data centers. This low-power profile is particularly important in hyperscale computing environments and sustainable IT initiatives.

Form Factor and Compatibility

The 288-pin DIMM form factor is a standard across server-grade memory, ensuring compatibility with a wide array of motherboards and server platforms that support DDR5 RDIMMs. The Supermicro MEM-DR564L-CL01-ER64 is engineered specifically for Supermicro systems but is generally compatible with most industry-standard motherboards and chipsets that support DDR5 Registered ECC memory.

Ideal for Supermicro Servers and Beyond

This module is optimized for integration with the latest Supermicro X13 platforms, which are built on Intel’s 4th Gen Xeon Scalable processors and AMD EPYC Genoa platforms. These systems leverage DDR5’s capabilities to achieve higher throughput and workload efficiency.

Use Cases and Applications for DDR5 64GB Registered ECC Server Memory

The high-capacity, high-frequency capabilities of the MEM-DR564L-CL01-ER64 module make it suitable for a wide range of enterprise and professional environments.

Cloud and Virtualization Platforms

Hosting virtual machines or containers requires memory that can support large data volumes with minimal latency. The 64GB capacity enables administrators to allocate substantial resources to each VM instance, maximizing server utilization and efficiency in cloud-native environments.

AI, Machine Learning, and Deep Learning Systems

Training neural networks and running inference algorithms necessitate high memory bandwidth and reliability. DDR5 RDIMMs with ECC are crucial in ensuring data accuracy while moving large datasets through pipelines and memory layers.

High-Performance Databases and In-Memory Analytics

Platforms like SAP HANA, Oracle, and SQL Server benefit greatly from high-density DDR5 memory. In-memory computing minimizes storage I/O bottlenecks, and ECC protection ensures database reliability and data integrity.

Financial Modeling and Real-Time Trading

Financial environments demand ultra-low latency and data accuracy. The MEM-DR564L-CL01-ER64 supports these use cases by delivering high-speed access to real-time trading platforms while preserving data integrity.

Component Quality and Thermal Management

Enterprise-grade modules like this Supermicro memory undergo rigorous testing and are built with premium DRAM chips, often from leading semiconductor vendors. In addition to performance, thermal characteristics are vital.

Thermal Sensors and Management Features

The module includes on-die thermal sensors that report real-time temperature data to the system’s firmware. Advanced BIOS/UEFI tools in Supermicro motherboards allow IT administrators to monitor these readings and adjust fan curves accordingly.

Passive Cooling Considerations

While the RDIMM itself is passively cooled, server chassis with high airflow are recommended to maintain optimal operating conditions—especially when running fully populated DIMM slots across multiple CPU sockets.

Future-Proofing Your Infrastructure with DDR5 RDIMMs

Investing in DDR5 memory like the MEM-DR564L-CL01-ER64 ensures that your infrastructure is prepared for upcoming developments in compute-intensive enterprise applications. With support for future generations of processors and chipsets, DDR5 memory modules offer long-term value for data center deployments.

Scalability for Multi-Terabyte Deployments

DDR5's capacity scalability means each DIMM can eventually scale up to 256GB, paving the way for servers with several terabytes of RAM. This Supermicro 64GB module is already a step toward that high-capacity future.

Compliance with JEDEC Standards

This module complies with JEDEC DDR5 RDIMM standards, ensuring cross-vendor compatibility, quality, and standardized performance metrics. Enterprises relying on multiple server brands or mixed memory configurations can safely integrate this module into their ecosystem.

Security Benefits Through ECC

ECC not only corrects single-bit errors but also detects multi-bit errors, which adds a crucial layer of protection against memory corruption—a growing concern in cybersecurity-sensitive workloads.

Comparing DDR5 RDIMM to DDR4 and LRDIMM Modules

While DDR4 RDIMMs and Load-Reduced DIMMs (LRDIMMs) remain in circulation, DDR5 RDIMMs provide clear advantages in performance and efficiency.

DDR5 vs DDR4 RDIMM

• Up to 2x data transfer rate (6400MHz vs 3200MHz)
• Lower operating voltage (1.1V vs 1.2V)
• Improved channel architecture with dual 32-bit subchannels per DIMM
• On-die ECC in addition to module-level ECC

DDR5 RDIMM vs LRDIMM

• LRDIMMs use a memory buffer for load reduction but introduce additional latency
• DDR5 RDIMMs offer a balanced approach with better latency and similar scalability
• Lower power consumption per bit transmitted

Dual and Multi-Channel Configuration

To take full advantage of DDR5 performance, configure memory in dual, quad, or even octa-channel modes, depending on the CPU and motherboard specifications. This allows the memory controller to distribute workloads evenly.

Firmware and BIOS Updates

Ensure your Supermicro server's BIOS and firmware are up to date to recognize and fully support the MEM-DR564L-CL01-ER64 module. Performance improvements and compatibility enhancements are often introduced via BIOS updates.
