Supermicro MEM-DR416L-SL04-ER26 DDR4 Memory

Supermicro MEM-DR416L-SL04-ER26 is a 16GB 2666MHz PC4-21300 ECC Registered DDR4 SDRAM module designed for high-performance enterprise server environments. Featuring a 288-pin RDIMM form factor, this memory module ensures maximum reliability, data integrity, and optimized performance for demanding workloads. It is ideal for data centers, virtualization platforms, and high-performance computing (HPC) clusters, where stable and scalable memory solutions are critical.

Capacity:16GB Memory

The MEM-DR416L-SL04-ER26 module offers a 16GB capacity per DIMM, allowing for efficient scaling in memory-intensive applications. With a frequency of 2666MHz and PC4-21300 performance rating, this DDR4 memory provides high-speed data transfer to support server workloads, including database management, virtualization, and large-scale computing tasks. The 1.2V operating voltage reduces power consumption while maintaining excellent performance, making it suitable for modern energy-efficient server architectures.

Error-Correcting Code (ECC) Technology

This Supermicro memory module employs ECC (Error-Correcting Code) technology, which detects and corrects single-bit memory errors automatically. ECC ensures data integrity and prevents system crashes caused by memory corruption, which is especially critical in enterprise environments where uptime and reliability are essential. By using ECC Registered modules, organizations can achieve higher system stability and protect mission-critical workloads.

Registered (RDIMM) and Single Rank Design

The MEM-DR416L-SL04-ER26 is a registered DIMM (RDIMM), which means it includes a register between the memory module and the system memory controller. This register reduces electrical load on the memory controller, allowing for higher memory density and better stability when populating multiple DIMMs per server. Its single rank x4 configuration offers an optimized balance between latency and throughput, making it ideal for servers that require reliable performance without compromising scalability.

Form Factor and Physical Attributes

The MEM-DR416L-SL04-ER26 uses a standard 288-pin RDIMM form factor compatible with most server DIMM slots. The module measures 133.35mm in length, ensuring proper fit in Supermicro server chassis. Its low-profile design allows for better airflow and thermal management inside dense server racks. With a single rank x4 layout, the module balances density and signal integrity, supporting multiple DIMM installations without degrading performance.

Memory Bandwidth and Latency

The 2666MHz frequency delivers a high data transfer rate of 21,300 MB/s, ensuring smooth handling of memory-intensive applications such as virtualization, database processing, and scientific simulations. With a CAS latency of 19 (CL19), the module provides a balance between speed and stability, minimizing memory access delays while maintaining reliable performance across all server workloads.

Thermal Management

Operating at a low voltage of 1.2V, the MEM-DR416L-SL04-ER26 consumes less power compared to traditional DDR3 or higher-voltage DDR4 modules. This reduced power draw not only decreases operational costs but also lowers heat generation inside server racks. Efficient thermal management ensures consistent performance and reduces the risk of server throttling or memory-related errors in high-density environments.

ECC and Registered Reliability

ECC and registered architecture are critical for mission-critical applications. Supermicro MEM-DR416L-SL04-ER26 undergoes rigorous testing to comply with enterprise reliability standards, ensuring that single-bit errors are corrected on-the-fly and multi-bit errors are detected before they impact system operations. Registered memory further stabilizes multi-DIMM configurations, making this module a reliable choice for 24/7 server operations.

Applications and Use Cases

In modern data centers, memory density and reliability are critical. MEM-DR416L-SL04-ER26 provides 16GB per DIMM, allowing IT managers to deploy high-capacity memory configurations across multiple racks. Its ECC and RDIMM design protect critical workloads in cloud environments, storage solutions, and virtualization platforms.

Registered vs. Unbuffered DIMMs

Registered DIMMs like MEM-DR416L-SL04-ER26 offer better stability for servers with multiple memory channels. In comparison, unbuffered DIMMs (UDIMMs) are typically used in desktops and small servers with fewer DIMM slots. RDIMMs help reduce electrical load on memory controllers, enabling higher memory capacities and improved signal integrity for enterprise applications.

DDR4 vs. DDR3 Memory

Compared to DDR3, DDR4 memory offers higher frequencies, increased bandwidth, and lower voltage operation. MEM-DR416L-SL04-ER26 delivers 2666MHz performance with ECC support, surpassing most DDR3 modules in speed, efficiency, and reliability. This makes DDR4 modules more suitable for modern server environments with demanding workloads.

Single Rank vs. Dual Rank Memory

Single rank x4 modules like MEM-DR416L-SL04-ER26 provide a good balance of performance and latency for multi-DIMM installations. Dual rank DIMMs offer slightly higher throughput but may introduce additional latency. For servers with high memory density, single rank modules help maintain stable performance across multiple populated DIMM slots.

Firmware and BIOS Updates

Keep server BIOS and firmware updated to support the latest memory features and compatibility improvements. MEM-DR416L-SL04-ER26 modules may require specific memory profiles (XMP or JEDEC) for optimal operation. Updating server firmware ensures reliable detection and performance of all installed DIMMs.
