Description
The Samsung M393AAK40B41-CTC4Q is a high-capacity 128GB DDR4 Registered DIMM (RDIMM) memory module, engineered for demanding server and workstation applications. This module utilizes DDR4 technology, offering significant improvements in speed, power efficiency, and density compared to previous generations of RAM. The 'Registered' aspect (RDIMM) means it includes a register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and greater stability in systems with many memory modules, such as servers. Operating at a frequency of 2400MHz (often designated as PC4-19200), this memory module provides substantial bandwidth for data-intensive tasks. The CAS Latency of CL17 indicates the number of clock cycles required to access a particular column of data, offering a balance between speed and performance. The '8Rx4' designation signifies an Octal Rank configuration with a x4 data width per rank, which is common for high-density modules and impacts how the memory is addressed by the system's memory controller. Crucially, this module supports ECC (Error-Correcting Code) functionality. ECC memory can detect and correct common types of internal data corruption, significantly enhancing data integrity and system reliability. This makes the M393AAK40B41-CTC4Q an ideal choice for mission-critical applications in enterprise environments, scientific computing, and data analysis where data accuracy and uptime are paramount. Its large capacity and robust design make it suitable for memory-hungry applications and virtualized environments.
