Samsung M321R8GA0BB0-CQK 64GB DDR5-4800MHz RDIMM 2Rx4 CL40 Memory

Product Description

The Samsung M321R8GA0BB0-CQK is a high-capacity 64GB Registered Dual In-line Memory Module (RDIMM) engineered for demanding server and workstation environments. It operates on the DDR5 platform, offering significant advancements in speed, bandwidth, and power efficiency over previous generations. With a clock speed of 4800MHz, this module is capable of handling intensive multitasking and data-heavy applications with ease, providing a substantial performance boost to systems that require high memory throughput. The module's 2Rx4 configuration indicates it is dual-rank, with each rank utilizing four data bits per memory chip. This configuration can improve performance by allowing the memory controller to access different ranks independently, effectively doubling the burst length and improving efficiency. As an RDIMM, it incorporates a register chip that buffers command and address signals, reducing electrical load on the memory controller and enabling higher memory capacities and speeds, which is crucial for server stability and scalability. Furthermore, this DDR5 RDIMM features a CAS Latency (CL) of 40, which is a measure of the delay between the memory controller requesting data and the data being available. While DDR5 introduces higher latencies compared to DDR4, the overall performance gains from increased speed and bandwidth typically outweigh this factor. This memory module is designed to be compatible with systems that support DDR5 RDIMMs and often includes ECC (Error-Correcting Code) functionality, which detects and corrects common types of internal data corruption, enhancing system reliability and data integrity.
