Description
The Kingston KVR21N15D8/16BK is a high-capacity 16GB DDR4 Unbuffered DIMM (UDIMM) memory module. It operates at a standard DDR4 speed of 2133MHz, identified as PC4-17000, and features a CAS Latency (CL) of 15. This module is built with a 2Rx8 configuration, meaning it consists of two ranks of memory chips, each with an x8 data width, which can offer performance benefits in certain system architectures by allowing the memory controller to access data from different ranks concurrently. This memory module is designed for compatibility with modern desktop computers and entry-level servers that support DDR4 memory. The UDIMM form factor indicates that it is unbuffered, suitable for systems that do not require the additional signal buffering provided by Registered DIMMs (RDIMMs). The standard operating voltage for DDR4 is 1.2V, contributing to lower power consumption compared to previous DDR generations. With its 16GB capacity and DDR4-2133MHz speed, this Kingston module is an excellent choice for upgrading system memory to improve multitasking capabilities, enhance application performance, and ensure smoother operation for demanding software. It is crucial to verify system compatibility with DDR4-2133MHz UDIMMs, including the number of ranks and total capacity supported, before installation to ensure optimal performance and stability.
