Product Description
This Samsung M386A8K40BM2-CTD6Y module leverages DDR4 technology to deliver enhanced performance and power efficiency compared to previous generations. As a Load-Reduced DIMM (LRDIMM), it incorporates a memory buffer chip that reduces the electrical load on the memory controller, allowing for higher densities and improved signal integrity, especially in systems with many memory modules. The 4Rx4 configuration indicates a quad-rank design with x4 data width per rank. This architecture can offer advantages in terms of bandwidth and performance in certain server workloads by allowing the memory controller to access different ranks concurrently. The CL19 latency, while not the lowest, provides a balanced performance profile suitable for a wide range of enterprise applications. Designed for mission-critical environments, this memory module supports Error-Correcting Code (ECC) functionality, which detects and corrects single-bit errors and detects multi-bit errors, ensuring data integrity and system stability. Its 2666MHz speed makes it compatible with a broad spectrum of server platforms that support this memory standard.
