Product Description
The Samsung M393A8K40B21-CTC is a high-performance 64GB DDR4 Registered DIMM (RDIMM) memory module, engineered for demanding server and workstation environments. With a substantial capacity of 64 gigabytes, this module is ideal for applications that require extensive memory resources, such as large databases, virtualization, complex simulations, and high-performance computing tasks. The DDR4 technology offers significant improvements in speed, power efficiency, and bandwidth compared to previous generations of RAM. This memory module operates at a frequency of 2400MHz, providing a data transfer rate of PC4-19200, which ensures rapid access to data for the CPU. The CAS Latency (CL) is rated at 17, indicating the number of clock cycles required to access a particular column of data. The 4Rx4 configuration signifies a quad-rank design, where each rank is composed of x4 DRAM devices. This multi-rank architecture can enhance memory performance and density, allowing systems to utilize memory more effectively, particularly in multi-processor configurations. As an RDIMM, the M393A8K40B21-CTC includes an onboard register that buffers address and command signals, reducing electrical load on the memory controller and enabling higher memory capacities and speeds. It also features Error-Correcting Code (ECC) functionality, which detects and corrects single-bit errors in real-time, crucial for maintaining data integrity and system stability in mission-critical applications. This Samsung memory module is a reliable choice for upgrading or populating servers that demand high capacity, speed, and data accuracy.
