Samsung M392A4K40BM0-CPB40 32GB DDR4-2133MHz VLP RDIMM 2Rx4 Memory

Product Description

This Samsung memory module, identified by SKU M392A4K40BM0-CPB40, offers a substantial 32GB capacity, making it suitable for memory-intensive server applications, virtualization, and large database operations. It operates at DDR4 speeds of 2133MHz, providing significant bandwidth for data processing. The module is a Registered DIMM (RDIMM), which includes an onboard register to reduce electrical load on the memory controller, enhancing stability and allowing for higher memory capacities in systems. The 2Rx4 configuration indicates that the module has two ranks, each composed of x4 (4-bit wide) DRAM chips. This dual-rank design can improve performance in certain server workloads by allowing the memory controller to access data from different ranks concurrently. The module also features a Very Low Profile (VLP) design, which is crucial for densely packed server chassis where height restrictions are a concern, enabling more DIMMs to be installed in a given space. As a DDR4 memory module, it operates at a lower voltage (1.2V) compared to previous DDR generations, contributing to reduced power consumption and heat generation within the server. It also supports ECC (Error-Correcting Code) functionality, which detects and corrects single-bit errors in memory, crucial for maintaining data integrity and system reliability in mission-critical server environments.
