The DELL KTD-PE421/16G memory module is a collaboration between Dell and Kingston, designed to provide high-speed, high-capacity memory for Dell servers and workstations. This 16GB DDR4 module operates at 2133MHz, providing a significant boost in data processing speed and efficiency compared to older DDR3 modules. The use of DDR4 technology not only increases the bandwidth but also reduces power consumption, making this module an eco-friendly option for businesses looking to minimize their energy usage. The 2Rx4 configuration signifies that this module has two ranks of x4 organization, enhancing its ability to handle parallel data streams and resulting in improved overall performance. The PC4-17000P classification indicates the physical and electrical design standard that the module complies with, and the P denotes it is a registered (buffered) DIMM, which ensures stability and reliability by adding a register between the memory modules and the system's memory controller. This feature is crucial in environments where many DIMMs per channel are required, as it helps to maintain signal integrity and system stability. Compatible with a wide range of Dell systems, this Kingston-manufactured module is an ideal choice for upgrading Dell servers and workstations, offering a blend of performance, reliability, and compatibility backed by two of the most reputable names in computing.
