Registered Dual Inline Memory Modules, commonly referred to as RDIMMs, are widely used in enterprise servers because they incorporate a register between the memory controller and DRAM modules. This design significantly improves signal integrity, especially in multi-DIMM configurations, allowing servers to scale memory capacity without compromising stability. The Supermicro MEM-DR464L-HL02-ER32 belongs to this advanced RDIMM category and is optimized for compatibility with Supermicro server platforms as well as other enterprise systems that support DDR4 registered memory.

High-Capacity 64GB Memory for Scalable Server Deployments

With a substantial capacity of 64GB per module, this DDR4 RDIMM category is ideal for memory-intensive applications such as virtualization, cloud computing, large-scale databases, enterprise resource planning systems, and in-memory analytics. High-density memory modules like this enable organizations to maximize memory per server socket, reducing the overall number of servers required and improving operational efficiency.

The dual-rank configuration further enhances memory performance by allowing better interleaving of memory access operations. Dual-rank memory can offer improved throughput compared to single-rank modules in many server workloads, making this category particularly suitable for enterprise environments that demand consistent and predictable performance under heavy load.

3200MHz PC4-25600 Performance Optimization

Operating at 3200MHz, the Supermicro MEM-DR464L-HL02-ER32 falls under the PC4-25600 classification, which delivers a theoretical bandwidth of up to 25.6GB/s per module. This level of performance is essential for modern processors that rely on high-speed memory access to feed multiple cores efficiently. As CPU core counts continue to rise, memory bandwidth becomes a critical factor in overall system performance.

This memory category is engineered to maintain stable operation at high frequencies, ensuring that enterprise servers can fully utilize the capabilities of Intel Xeon and AMD EPYC processors that support DDR4-3200 memory speeds. The optimized timing configuration, including a CAS latency of CL24, strikes a balance between speed and reliability, making it suitable for both compute-intensive and memory-bound workloads.

CAS Latency CL24 and Its Impact on Workloads

CAS latency, often abbreviated as CL, refers to the delay between a read command and the moment data becomes available. With a CL24 rating, this DDR4 RDIMM category is optimized for enterprise stability rather than aggressive overclocking. In server environments, predictable latency and error-free operation are far more important than marginal gains in raw speed.

The CL24 timing ensures compatibility with a wide range of server motherboards and BIOS configurations, reducing the risk of instability during continuous operation. This makes the Supermicro MEM-DR464L-HL02-ER32 an excellent choice for 24/7 data center deployments where uptime and consistency are paramount.

Dual Rank x4 Memory Organization

The dual-rank x4 configuration of this DDR4 RDIMM category plays a crucial role in performance and reliability. Dual rank means that the memory module is organized into two logical ranks, allowing the memory controller to alternate access between them. This interleaving can improve effective bandwidth and reduce latency under certain workloads.

The x4 organization refers to the width of individual DRAM chips used on the module. x4-based ECC memory provides stronger error detection and correction capabilities compared to x8 configurations, which is why x4 RDIMMs are often preferred in enterprise and mission-critical server environments.

DRAM Is Preferred in Enterprise Servers

x4 DRAM chips allow ECC to detect and correct a wider range of memory errors, including certain types of chip failures. This enhanced fault tolerance is especially important in large memory configurations where the probability of hardware faults increases over time.

For organizations prioritizing maximum data integrity and long-term reliability, the x4 dual-rank design of the Supermicro MEM-DR464L-HL02-ER32 category provides an added layer of protection that aligns with enterprise best practices.

1.2V Low-Voltage Operation for Energy Efficiency

This DDR4 RDIMM category operates at a nominal voltage of 1.2V, which is standard for DDR4 technology and represents a significant improvement over previous DDR3 generations that required higher operating voltages. Lower voltage operation translates directly into reduced power consumption and heat generation, both of which are critical factors in modern data centers.

By reducing overall energy usage, servers equipped with low-voltage DDR4 memory can achieve better thermal efficiency and lower cooling costs. This makes the Supermicro MEM-DR464L-HL02-ER32 an attractive option for organizations focused on optimizing total cost of ownership while maintaining high performance.

The 288-pin RDIMM form factor is the standard for DDR4 registered memory modules, ensuring broad compatibility with enterprise server motherboards. This category is designed to integrate seamlessly into supported Supermicro systems as well as other OEM platforms that adhere to DDR4 RDIMM specifications.

Proper pin configuration and adherence to JEDEC standards ensure reliable electrical connectivity and signal integrity. This compatibility reduces deployment risks and simplifies memory upgrades or expansions in existing server infrastructures.

Seamless Integration with Supermicro Server Platforms

Supermicro memory modules are rigorously tested and validated for use with Supermicro server motherboards and systems. This validation process ensures optimal compatibility, performance, and reliability, minimizing the likelihood of firmware conflicts or unsupported configurations.

For organizations standardizing on Supermicro hardware, selecting memory from this category helps maintain a cohesive and fully supported infrastructure, simplifying maintenance and support processes.

Use Cases Across Enterprise and Data Center Applications

This DDR4 RDIMM memory category is well-suited for a wide range of enterprise applications. In database servers, the high capacity and bandwidth support faster query processing and improved transaction throughput. In virtualization hosts, large memory capacity per module allows higher virtual machine density without sacrificing performance.

High-performance computing workloads also benefit from the reliable, high-speed memory access provided by DDR4-3200 RDIMMs. Scientific simulations, data analytics, and AI preprocessing tasks can all leverage the consistent performance characteristics of this memory category.

Database and In-Memory Computing Performance

Modern databases increasingly rely on in-memory processing to achieve low latency and high throughput. With 64GB per module, this memory category enables large portions of active datasets to reside directly in memory, reducing reliance on slower storage tiers.

The combination of ECC protection, high bandwidth, and stable latency makes the Supermicro MEM-DR464L-HL02-ER32 an excellent choice for enterprise database environments where data accuracy and performance are equally critical.
