Overview of Samsung M386A8K40BM1-CRC4Q DDR4 LRDIMM

The Samsung M386A4G40DM0CPB 32GB DDR4 2133MHz PC4-17000 Reg SDRAM LRDIMM 288-Pin Memory Module belongs to a specialized category of enterprise-grade server memory engineered to deliver exceptional reliability, scalability, and performance stability in demanding data center environments. This category focuses on Load Reduced DIMM technology combined with Samsung’s advanced DDR4 manufacturing processes, enabling high-capacity memory configurations without compromising signal integrity or system efficiency. Designed for modern server platforms, this memory category plays a critical role in virtualization, cloud computing, enterprise databases, and mission-critical applications where consistent uptime and predictable performance are essential.

DDR4 2133MHz Performance Characteristics

This memory category centers around DDR4 technology operating at 2133MHz, also identified as PC4-17000. DDR4 represents a significant generational advancement over DDR3, delivering improved bandwidth efficiency, lower operating voltage, and enhanced data integrity. The 2133MHz speed grade ensures balanced performance for enterprise workloads that prioritize stability and compatibility across a wide range of server platforms rather than peak clock speeds.

Signal Integrity and Timing Stability

Within this category, precise timing and signal integrity are essential attributes. The Samsung M386A4G40DM0CPB module is engineered to maintain consistent latency characteristics under sustained load. This ensures predictable system behavior, which is critical for enterprise environments where performance consistency often outweighs marginal speed increases. The DDR4 architecture improves command/address bus efficiency, reducing electrical noise and enhancing overall system stability.

Load Reduced DIMM (LRDIMM) Technology Overview

A defining characteristic of this category is the use of Load Reduced DIMM technology. LRDIMM modules incorporate a memory buffer that isolates the electrical load of the DRAM chips from the memory controller. This design significantly reduces the load presented to the CPU’s memory controller, allowing servers to support higher memory capacities while maintaining signal integrity and stability.

Comparison with RDIMM and UDIMM Categories

Unlike Unbuffered DIMMs, which are commonly used in consumer systems, and Registered DIMMs, which buffer only the address and command signals, LRDIMMs buffer both data and control signals. This comprehensive buffering approach allows servers to populate more DIMM slots per channel without compromising stability. As a result, this category is positioned above standard RDIMM memory in terms of maximum achievable capacity and scalability.

High-Density Memory Deployments

Servers utilizing memory modules from this category are often deployed in virtualization hosts, in-memory databases, and analytics platforms. These workloads benefit from high memory density, as it reduces the need for disk I/O and improves overall application responsiveness. LRDIMM-based systems can consolidate more virtual machines or handle larger datasets within memory, delivering improved performance efficiency.

32GB Capacity Advantages in Enterprise Systems

The 32GB capacity of the Samsung M386A4G40DM0CPB positions this category as a versatile solution for both mid-range and high-end servers.
